Build audacity with ASIO support on Windows

Build your own Audacity for Windows with ASIO driver support

Due to licensing restrictions the Audacity team cannot provide a prebuilt version with Windows ASIO driver support. But with this guide and script you can easily build your own Audacity with ASIO support.

This builds the latest Audacity release 3.4.2 by default. If you want 3.3.3 then use "build-audacity.cmd -v3.3.3".

ko-fi

Background

Drivers are the glue between an audio program like Audacity and external hardware like a mixer or sound interface. The drivers usually used on Windows have limitations which can be overcome if you use ASIO drivers for your hardware. Specifically, low latency (delay) and multi channel support are available with ASIO drivers.

The Audacity program is the "go to" solution for many audio recording and editing tasks. However, unlike many more advanced DAWs, it doesn't support Windows ASIO drivers "out of the box". Fortunately, Audiacity's standard MME support is fine for most uses. That said, common reasons for needing ASIO include using digital audio or music equipment that only comes with ASIO drivers, such as Behringer mixers (which actually suggest using the less efficient ASIO4ALL ASIO to WDM bridging driver). Another common reason is to take advantage of the low latency or multiple channels supported by ASIO. Note that Audacity really is not a good multichannel solution, so if that is required a DAW might be a better bet.

While it is possible to build your own Audacity with ASIO support by following the instructions this usually requires considerable technical skills.

But have no fear, the instructions and script provided here make it easy to build your own version of Audacity with ASIO support. You just need a suitable Windows PC. The script installs all required tools and builds a 64 bit release version of Audacity with ASIO for you using the official build instructions.

NB. If you do use this to build Audacity with ASIO support you must not redistribute it due to the ASIO SDK licensing terms - see below.

Here's a brief blog post explaining why I needed ASIO and it includes a screen shot. But note, since writing that, I discovered my McMillen K-Mix digital interface mixer facilities alow routing of inputs 3 & 4 to the main outputs on 1 and 2 so can use the default MME Audacity build after all. For playback from PC, I found the HiFi Driver and ASIO Bridge from VB Audio lets me re-route PC audio out to channels 3 & 4 on the K-Mix, Leaving Channels 1 & 2 free for instruments and Mics.

Licensing

The reason for Audacity's lack of ASIO support is licensing, not technical. Steinberg do not alow the ASIO SDK to be redistributed (as required by open source projects). In addition, Audacity is GPL licensed and so is incompatible with the ASIO SDK licence redistribution rules.

Development PC

The script installs a set of development tools that are known to build Audacity. Due to the complex nature of such tools, any other versions of them on your PC may interfere with this script. Thus this scipt should be run on a clean PC without any developer tools. No support can be offered otherwise.

If you would rather not install these tools (Git for Windows, Visual Studio, CMake, Python and Conan), or you already have versions of them or even if you are having build problems, you can use a one of the following Vitual Machines:

  • Windows Sandbox - Sandbox can be enabled on Windows 10/11 Pro/Enterprise and can also be installed on Windows Home with a bit of effort. If the build experiences memory errors you will need a configuration file to provide more memory than the default 4GB.
  • A virtualisation program - install a VM and and a matching Developer Virtual Machine Image from Microsoft. In most cases VirtualBox will be a good choice (import the Microsoft supplied .ova appliance file but the Visual Studio pre installed in the VM must be uninstalled first to avoid problems).

In both cases you can copy the built files to where they will be run from on you PC file system, possibly by sharing a PC folder with the VM.

Step by Step Instructions

  • Ensure you have a PC (or VM) with Windows 10 or 11 installed.
  • Make a new folder C:\projects.
  • Click on the 'raw' button at the top of the script (below) in this Gist.
  • Use the browser Save As (right click) feature to save the script as This PC -> C:\projects\build-audacity.cmd. To avoid it being saved as a text file type the filename in quotes, eg "build-audacity.cmd".
  • open a new Windows cmd terminal (Windows + R keys and then type cmd)
  • Type cd \projects and enter key.
  • Install required tools and build by typing build-audacity.cmd and enter (use -v3.3.3 if requred).
    • Follow the prompts, pressing a key to start each tool's installer (when previous has finished).
    • NB for Visual Studio, make sure you check the "desktop development with C++" workload
    • If you have a non English Windows or Visual Studio then you must also install the English language packs.
  • Come back later - it will take at least 10 minutes.
  • Audactiy will be launched to test it was built correctly.
    • See the program location printed out at the end of the build so you can run it again.
    • Optionally copy the specified folder to where you want to run Audacity from, optionally renaming it.

(This video by @Renamesk walks you through the process, but the tool installation method has changed.)

If you have any ASIO drivers installed for active connected hardware you should find ASIO is now available in the the Audacity driver selection combo box which probably currently shows 'MME' selected (you may need to show using menu item View -> Toolbars -> Device toolbar).

NB: The Audacity settings and preferences are stored in a folder "Portable Settings" next to the audacity program. If you want to use settings in the user's home directory then delete this folder.

When things go wrong

As with any complex software build there are many moving parts (including Windows itself) and things can sometimes go wrong. Here are some tips if you hit build errors.

If everyhting falls or you just want to shortcut lots of painful debugging then try a Microsoft Windows Virtual machine (VM) as mentioned above.

  • make sure you have latest script
  • make sure you are in a folder C:\projects in the cmd window
  • ensure you are an administrator on your Windows 10 or 11 64 bit PC (ie not a organisational PC)?
  • run the script with --cleanall and try again
  • uninstall all the tools and installers (Python, cmake, Visual Studio) and then reboot before trying again
    • note having other versions of any of the tools installed may well cause problems - remove them
  • ensure you ticked the specified options when installing Visual Studio and Python, reinstall if unsure
  • read the error output - clues are often buried in reams of impenetrable text
  • disable any Anti Virus - the built-in Microsoft one is usually not a problem
  • if your PC is not English make sure you have EN language packs installed for Windows and VS

Thanks

All I get is "Error: Cannot create Audacity buildfiles" over and over cmake just gives a conan error when I try to build in there. I have been at this all day somehow I feel Audacity is just not worth my time.

@ZardozXerxes So sorry to hear your frustration. Tech build can so often be like that, there are so many variables to get lined up. Can you use the release Audacity without ASIO while you try to figure this out?

I've just tried again and all is well with the script. So there's something not quite right with your setup. We'd need more info to help.

Are you building 3.3.3 (the default) or -3.4.1 (needs -v3.4 option)? 3.3.3 is still the most reliable.

Please ensure you have followed the instructions EXACTLY. Here are some key points

  • Do you definitely have the latest script version 2.2.2? Re download to be sure.
  • Are you an administrator on your WIndows 10 or 11 64 bit (ie not a organisational PC)?
  • Make sure you are in a folder C:\projects in the cmd window
  • If your PC is not English make sure you have EN language packs installed for Windows and VS
  • Ensure you ticked the specified options when installing Visual Studio and Python (you probably did)
  • You could try the --cleanall and then --cleaninstall options (seperately) to delete any files lying around

Best of luck!

@ZardozXerxes I did find a small bug but only if not using the specified --install option. Please try new script version 2.2.3

Copy link

ghost commented Nov 11, 2023

I already have Audacity but I need to record from my UA Apollo Twin X line in and that can only be done via ASIO.
Yes I had version 2.2.2, I just ran the scrip I did not change the version so I presume it was 3.3.3, yes I am admin, yes I am in the specified folder, I am in English, I had already specified the options from trying and failing to build it myself using Cmake, I tried the --cleanall a few times but not the --cleaninstall as I was just following the instructions as written, that said I did clear the entire project folder a few times. I will try the new script. Unrelated but I think this might be a typo "follow the prompts, pressing a ket to start each tool's installer in turn".

ghost commented Nov 11, 2023

I tried the new script many times and got the same error, I thought it might be a conan version error or conflict so I checked if it was already installed and it was not, so I tried installing it first and then with it uninstalled. Here is the error in full.

@ZardozXerxes Oh dear.

I just released script 2.2.4 so you should try that (though earlier should have worked) As there is so much I do not know about your set up best you do a clean build from the top.

I did spot you have python 3.12 and I got errors building due to conan dependency problems. The script installs python 3.11 Use that!

  • Uninstall Visual Studio and Python and their installers - 4 programs
  • run "build-audacity.cmd --cleanall"
  • run "build-audacity.cmd" or "build-audacity.cmd -v3.4.1" The --install option is now the default

If that doesn work I'm at a loss

SteveALee commented Nov 11, 2023

[Update] The --install option is now the default as that is most likely what most people will want. The --build option will build with out installing build tools first.

ghost commented Nov 12, 2023

@SteveALee Yes I thought of that too and uninstalled all versions of python but the result was the same. 2.24 is not working, the same as the last. The only things installed now are Git For Windows and Visual Studio before I run the script. This is the first thing I have ever tried to build from git hub (and probably the last after this) so I have no idea why it isn't working.

2.24
What is that? The script will build 3.3.3 or 4.2.1. The dependencies are way too complex to support more

The only things installed now are Git For Windows and Visual Studio before I run the script
Why is VS installed. I suggested you uninstalled it first. I know it's slow but otherwise you are not in a state I can support. What VS pre installed before you tried to build? If s owhat version? i try to be clear in the instructions that if you already have a dev env setup then they may well be problems due to tool dependencies.

Oh you should check no CMAKE is installed.

You can't really blame github -this is gist (lol) though yes it does fetch the source from git. That's incredibly common. The problem is most likely something to do with your specific PC config being out side the tested bounds. It happens sadly. So do you build other software? Again that indicates you might have a dev env on your PC that might clash.

Stop complaining, spring up plain Win 1x VM in whatever (Hyper-V, Virtualbox, VMware player etc) and run the script. The result will be surprising, it will just work

after you can ditch the VM and get back to your setup

Hi @SteveALee , thanks for this amazing script.
I have used the Sandbox in Windows 11. Maybe a bit slower, the whole process took almost an hour, but worked great.
I had some issues with the result. It kept crashing. First it complained about missing avformat dll's. I installed FFMpeg to solve that issue. The second was the language. Audacity used 'Dutch' as language. After switching it to English, I was able to record all 15 tracks of the Rodecaster Duo.
BTW, I used the version of a few days ago. I will try to build the new script as well to get Audacity 3.4.2

Thanks again for the amazing script! And I just bought you a Ko-fi :)

@lammersma wow, I completely forgot about sandbox! I tried once when it launched and found it a bit buggy. Thanks for the tip. That is rather slow, but VirtulBox is not fast (VMware player is useless if using Hyper-V, eg for WSL).

I think there are plenty of crashing bugs left in 3.4.x :D but 3.4.2 does seem better. I'll leave the script defaulting to 3.3.3 for a bit longer.

The Language thing is weird. Maybe the sandbox is not quite localised correctly. Good to know you fixed it and it is actually useful!! Even better to know you brought me a ko-fi!!

@scerazy

I came here for help not trolling and disrespect, nothing I have said is complaining I am just trying to get it to work.
Creating a VM is not a solution, this should work without a clean version of windows or its not much use to anybody.

@SteveALee

I bumped the Audacity version to 3.3.3 - https://github.com/audacity/audacity/releases/tag/Audacity-3.3.3

Maybe I'm not sure what does "bumped" mean, but it looks like a real Audacity without ASIO. As I told you before Audacity works fine, it's the version compiled with ASIO who doesn't work. So yeah, the 3.3.3 works, but 3.3.3 with ASIO doesn't work. Same for the 3.3.2. I don't know if you see what I mean ?

Perhaps having all hardware connected at once is confusing audacity. But you say even with just one. Or all the drivers?

I tried with all hardware connected at the same time, and only with one connected. Something's blocking and I can't find what and why..

No I don;t speak French - looks good though. My wife is learning :)

👍👍

did you try an ASIO DAW or some such to confirm the problem is with Audacity?

Yep. As far as it's my job, I'm using everyday Mixcraft, sometimes ProTools or Cakewalk or Studio One. Never had any issues with them.

To resume : Audacity works fine but doesn't record in 32 bits float, that's why I'm trying to compile it with ASIO, and when it's compiled it doesn't open and get stuck on the splash screen. Sometimes it asks for the ASIO driver but still gets stuck, and most of the other times I don't have the popup for ASIO selection. I tried to compile and recompile again and again and again, I don't know how to force this popup to be shown ! It's seem to be a random thing.

Hey guys, it still doesn't work with me. 🙄
I've tried to turn my Windows in English only, installed EN lang-packages for VS, etc.. Done everything's written on this README part, also tried to download ASIO SDK as in the video, etc..
Nothing seems to work at all, I still get stuck on the splash screen of Audacity. Tried on 2 computers. Same result. Even with the new 3.4.2 version.
How-the-hell did you all make it work ?!

Maybe.. Can anyone send me his compiled and working Audacity-ASIO version ? To see if it works fine with me ?

"You can't really blame github -this is gist (lol)" - I am not blaming anything I just said that this will be the last time I try to build anything from Github, also I a am not just referencing this script page as I mentioned before I came here I was trying to build it on my own directly from github and that wasn't working thats why I ended up here.
I already said "The only things installed now are Git For Windows and Visual Studio" so no Cmake is not installed.

@scerazy @Sky3RN @ghost I'm sorry you are all having problems. Sadly there is such a incredibly wide range of possible PC configs that some will just fail. I have tested on the few I have access to. This all takes time and I provide this as a voluntary service for the Audacity community.

If you do not want to run a VM as a hopefully clean working environment then can you try another PC? You can just copy the built files. What you can't do is give to other people under steinbergs licence conditions. Someone just mentioned success building with the windows Sandbox, a kind of simple built in VM.

If it build but does not run then I suggest talking to the project devs. FYI Audacity on my main PC takes ages to start, the splash dissappears but it does eventually start up.

I wish you luck.

@scerazy @Sky3RN @ghost do make sure you grab the latest script and use the --cleanall. Also uninstall VS and python for the best chance of it working.

My goal is to make it work on a real Windows machine, not a VM. I need it to work for a real time usage, and most of all, not for me but for all the people who are trying to record in 32 bits float as I mentioned before. But this is a struggle.. Argh.
I don't know what Sandbox is and if it's too hard to make it work it's not worth it. I mean, I'm a sound engineer making videos on YouTube to explain why people should buy a 32 bits float soundcard and it works fine with any DAW but not with Audacity, and noobs people who are watching my videos use Audacity. 😅 If it wasn't for them, I would have never used Audacity. I hate this Audashitty. 😃
In that way, people won't use VMs or Sandbox or something else. They need it to work on their own machine. They don't even know how to access an URL without using Google. 🙄

I already tried to tell them but they are closed-minded like « The problem doesn't come from Audacity » blah blah blah.

After compiling Audacity with ASIO successfully for nearly one year by using this great build-tool I got strange results in the last week: The build process (build-audacity.cmd version 2.2.6) is running in my VM (Win 10) successfully, but the started Audacity version 3.4.2 is missing the "Libraries" command in Edit->Preferences. Normally it is listed between Import/Export and Directories. Therefore I can't use ffmpeg in Audacity any more and can only open .aup3 projects, no audio import or export. Looking in Help->About Audacity->Build Information it says ffmpeg is enabled. I also tried to install FFmpeg for Windows in my virtual machine and rebuild it, but without success. This problem started with version 3.4.1. I would be greatful for any advice.

@haberl333 I have just been informed there is a change to the build process to build everything but the build docs were not updated. You're the second person to have ffmpeg problems. My basic smoke test passed though.

I'll look at this ASAP.

Thanks for this quick answer. I just found a solution/workaround. Up till Version 3.4.0 alpha it was sufficient, to copy all files from release directory in my VM to any directory in my main machine, add subdir Portable Settings to get a new portable version (I cannot bring myself to delete old running versions). And that is the problem with the latest builds like you mentioned. To workaround this I installed an official Audacity without ASIO (exactly same version!) and then copied all the self builded files on it, and voila I found Libraries command again. Moreover I copied all the files of the official install directory in c:\program files\audacity... back to my personal local directory with Portable Settings subdir included and also this version now works well...

Nevertheless many thanks for your build-command file, and I hope you will find time for future updates .

BTW: I also had problems in the beginning with version 3.4.0. And I solved it, by cleaning my VM from my Visual Studio Community version included C# support.

Hmm thanks. It was always possible to copy the built version files without officially making in any sort of portable app. Seems I need to dig. Progress hey!?

Updated script to build all components including plugins for FFmpeg etc. Also creates the "Portable Settings" folder for preferences.

Thanks @haberl333 and Ed Witles for helping to identify and fix the issue.

[Update] Version: 2.4.0 of script now installs Git for Windows. Also better at updating path on install.

@rhcaldwell definitely made with love and quite a bit of labour given windows cmd script! Lol. It usually just works. Good luck.

Hi Steve, I appreciate all the work you have done to generate the script. Thank You. You've more than earned my Kofi. Unfortunately I'm having some problems getting the script v 2.4.0 to work. I don't have the skills to fix it and I'm hoping you can give me some pointers please.
I'm running the script in Sandbox on a Win 11 laptop and aiming to build Audacity v 3.4.2 with ASIO. The first problem I hit was when it got to the build stage it halted on error "Python does not appear to be installed...". I had definitely ticked the 'Add python.exe to path' box and left the other installation options at the defaults. When I checked I found that python.exe, gw4.exe and vs.exe had all been installed in c:\projects\bin. So from an elevated cmd prompt I added that directory to the path and ran the script with "--build". It ran but produced over 100 warnings and over 330 errors and then reported 'unable to build Audacity. I repeated the process a few times to be sure I'd followed the instructions correctly but with the same results. I'd appreciate any pointers.

Then I tried to set the python install directory to C:\programs when the install window came up.. The installer still put it in C:\bin.

I'm guessing this is a Sandbox problem that the script can't fix and I need to try another VM?

Regards
Alan

@GrumpyOldDrummer (love the name) oh dear. I've not tried the sandbox for a while so will test again. The script might not need python to be on the path now - it uses relative paths - or it should. But you made a good call in trying to fix. I'll try on a really clean PC to check. Sorry for the problems.

@GrumpyOldDrummer oh shoot I don't have windows pro around anymore as didn't need the extra features to justify extra cost. I have an old windows 10 PC I can try.

@GrumpyOldDrummer OK I made small change to compensate for different Python installer behaviour in a Sandbox. Download the new script, uninstall Python and try a full install again (you can cancel the git and VS installs).

It worked! Thanks Steve. When I first ran it I got several hundred of out-of-memory errors. I understand the sandbox memory defaults to 4GB so I increased that arbitrarily to 10GB by creating a .wsb file and then it worked.

@GrumpyOldDrummer yay!

It just worked on my clean install Windows 11 Pro. But very slow and terminal font changed for the worse half way through.

Out of interest what will you be using ASIO with?

@GrumpyOldDrummer

@SteveALee
The build ran cleanly on my laptop after your tweaks and the memory allocation increase. I will be using it with a Behringer UMC202HD on my laptop and with a RME UFX+ on my studio setup. I just tested it with the RME and it works perfectly. I normally run Cubase there but I've been using Audacity macros to process some old band cassette recordings from the 1980's.
Thanks again Steve. Top Man!

@GrumpyOldDrummer nice, Behringer kit seems a common use case. The Audacity multi channel experience needs some work but latency will be better than the ASIO 4 All hack that's often proposed.

Now builds 3.4.2 by default

@SteveALee
You are right that multi-channel record needs some work. I spoke too soon about it working perfectly with the RME. I cannot find a way to display and record on selected channels only. i.e. If I want to record channels 11 and 12 only I have to select 12 inputs channels. It puts all 12 on the screen and records on 11 and 12. If I hide the unused channels it doesn't record on 11 and 12. Sigh... Playback is fine. All is fine with the 2 channel Behringer box.

Yeah, it sucks big time. One day if I get more time!.... In my notes in the gist I mention a little app that will route channels. It might help.

@GrumpyOldDrummer just discovered VB Audio Matrix which might provide a partial workaround for Audacity's lack of multitrack usability,:

I think it will let me use both of my interfaces without lots of config changes.
