Build audacity with ASIO support on Windows

Build your own Audacity for Windows with ASIO driver support

You might want Audacity to work with the ASIO drivers supplied with your sound devices. Commmon reasons for this are:

  • Only ASIO drivers are available for your hardware (eg Behringer mixers)
  • Performance - ASIO has low latency (delays)
  • You don't want to use the ASIO4All bridging driver with non ASIO drivers
  • Multi channel support - though Audacity is not so good at handling other than Stereo or Mono

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, on a Windows PC.

This builds the latest Audacity release 3.7.0 by default. Recent other versions can be built with the -v option

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

I might think it could be a driver compatibility issue but.. Which one ? I'll have to uninstall all the drivers to find out the messing one ! I'll try.

Sadly that is probably your sensible next step. Uninstall all and add one at a time. Don't you just love computers! I'd try only the 32 bit one first as that's a bit unusual. I assume Audacity supports 32 bit OK?

@Giermann

@Sky3RN

And I already tried to uninstall the tools and reinstall everything with your script !

Remember: the script offered here and the post-installed tools are only to compile Audacity!!
They neither affect the runtime of an ASIO build, nor are they necessary on every target machine.

You already wrote, that you checked your built portaudio_x64.dll with an original distribution and vice versa. Another option would be to share (NO - not to publish, only to share for testing) your built DLL with another person and/or get a running version from him or her. That way you could verify if it is really a driver issue with your drivers or a fault at build time.

@Sky3RN thanks @Giermann

I assumed you had no errors in the build and audacity was launched at the end? It seems so from what you say.

if you want to check for any errors / warnings you can run the following to build and send all output the file out.txt. But again I can;t really support you on build errors

build-audacity.cmd --clean > out.txt 2>&1

I just tried ! I've uninstalled all of my ASIO drivers, recompiled Audacity and.. Still doesn't work.
Yes it normally should support 32 bits float because it's working on Linux natively, didn't have to compile with ASIO.

It's easier on Linux.. I'm not really familiar with Windows.

Any reason not to stick with Linux? It's been a decent desktop experience for a long time now. Is it availability of other software? Out of Interest which distro?

The reason is more complicated than that ! I use Linux everyday for my "everyday tasks" as I could say. I use Windows only for two things : Recording / Mixing, and video editing. I never use Audacity, I'm not a big fan of this software. But the reason why I'm trying to get this thing fixed is : As a sound engineer and YouTuber talking about sound, a lot of my audience are noobs using Audacity and nothing else. I recently did a video testing the new Zoom UAC-232 which is capable to record in 32 bits float, and I noticed it doesn't work on Audacity. In fact, it works fine with Audacity on Linux, but not with Audacity on Windows. By "doesn't work" I mean it's recognized but doesn't record in 32 bits float in Audacity for Windows 10. That's why I'm trying to know why. And all of my researches led me to this point : Maybe it could come from this ASIO not supported natively on Audacity.

I tried with 2 different ASIO,

So it fails with two different manufacturer's drivers? Might be safe to assume doesn't work with any ASIO drivers? Hmm. I only have a McMillen ASIO driver. Will try to test a new build with it over next few days to ensure something did't go wrong when I bumped the Audacity build version.

Exactly, failed with the PreSonus driver and the Zoom driver. I've seen your script installs Audacity 3.3.2 and now the official release is 3.3.3, maybe it could be the cause ? I don't know. I'm not an expert in dev !

never use the sh*tty ASIO4All.

Good plan. AFAIK it's only for use with ASIO only apps when you have no ASIO drivers. Trouble is many manufacturers got lazy and suggest you use it rather than supplying ASIO drivers. Not multi channel and not latency gains. Sigh. As you say "sh*tty " :)

😁😁😁

The drivers from zoom for their smaller devices have always set the datachunk and native sample rate the computer will be "looking" for from the device. When this doesn't match up (usually DAW software to datachunk size for speed and memory use, Native sample rate to what's on the device itself) you can get all kinds of issues, from sound not showing up to driver not showing up. Also, 32bit windows doesn't exactly have an audio capability for 32bit float natively. I know this because every audio app I've tried in the 32bit versions only goes as high as 24bit. With Linux, you didn't have this problem because linux was 64bit only for a long while before 64bits became the norm for most Windows installations. If you are stuck with a 32bit windows, you are almost always limited to 24bits, 96k, accept with one or two software titles (can't remember which). If you are compiling a 64bit version and still don't get 32bit float (I've had no experience with your device here, so grain of salt), it may be connected to the driver, though I have seen that the device can use 24bit and the system 32 without problems in Adobe Audition. My experience with zoom devices has been that there is a driver interface that you can access to set the sample rate and the data chunk, but the device must be set to the right mode or you will not get audio; or you will get a message in your DAW that it isn't working. My H6 has 2 drivers installed. One is a simpler L\R stereo driver, another is the multitrack driver. If I set the device to Stereo for the connection and the PC for Multitrack, no go. If I set the data chunk wrong, the sound fragments. The sample rate can be higher than the project file, but lower and it'll stutter and possibly flag errors, showing you a thousand popup messages for all the samples you drop.
And the ASIO4ALL driver is not actually an ASIO driver, but an attempt at a clone of it. While I have always had access to the 32bit driver in 32bit Audacity, I haven't tried 64bits.
Here are the possibilities I can see:

  1. The DLL you are using is corrupted, replace it with a clean download.
  2. The DLL may be flagged as a "Dangerous" file by an AV like Windows Defender, fix that by allowing the file.
  3. The script is downloading new versions that mismatch (unlikely, but possible)
  4. If the DLL is the result of a Build operation, the build is done but one of the binaries or project files is missing or corrupted.
  5. You need to set your path variables on your own, since you may have UAC issues with that (a nasty little gift from Windows 7 that is helpful on occasion).

@htdSoundTech2020 Thank you for your insights! It's a little hard to parse the one big paragraph but some thoughts.

  • This gist only automates the Audacity project build so any technical issues using Audacity need to be raised with the project team,
  • While the 32 Bit float audio resolution is not directly related to platform bit size, it makes sense 64 bits is required. To be honest older 32 bit platforms are likely to hit all sorts of support issues.
  • Yes ASIO4ALL is not ASIO - but this point confuses many due to the inaccurate name ASIO-fake or fauxASIO would be better. It makes normal windows sound appear to be the ASIO interface that Apps that require ASIO drivers demand. You don't get any of the ASIO benefits.

I use Windows 10 Pro (19045.3448).

I tried --cleanall a few times.

I will try build once again and I will try post the erros in the end of the proccess.

@mateusfig @Giermann O wow,

so it seems to be barfing when trying to link to create a libsndfile conan component

That in turn maybe caused by this:

C:\Program Files\Microsoft Visual Studio\2022\Community\MSBuild\Microsoft\VC\v170\Microsoft.CppCommon.targets(249,5): warning MSB8065: Custom build for item "C:\Users\mmachado.conan\data\libsndfile\1.0.31__\build\899d2c53f1b9e4a7deb461e3cf1716f2d4fd697d\build\CMakeFiles\bf18e4cabeda36cd82ee3e51ae56b6cc\sndfile.def.rule" succeeded, but specified output "c:\users\mmachado.conan\data\libsndfile\1.0.31__\build\899d2c53f1b9e4a7deb461e3cf1716f2d4fd697d\build\src\sndfile.def" has not been created. This may cause incremental build to work incorrectly. [C:\Users\mmachado.conan\data\libsndfile\1.0.31__\build\899d2c53f1b9e4a7deb461e3cf1716f2d4fd697d\build\sndfile.vcxproj]

There were a LOT of warnings for that file which to me is a code smell but might have been expected.

I noticed some output text "Versão do MSBuild 17.7.2+d6990bcfa para .NET Framework" and previously a French native had problems which caused us to mention in the Gist instructions that English language packs might be required for both Windows and Visual Studio. The errors don't indicate language filename problems, but perhaps something to do with incremental build (why?)

Otherwise I'll have to pass over the @Giermann

When I have time I'll compare to me logs

As we have no idea what kind of mess Microsoft might have made of language dependencies (if any) I I would uninstall/reinstall everything and be sure to run --cleanall. Sorry for this pain.

First of all, markdown language seems not to be the best choice to paste large text files. Maybe you should better use another service, for example pastebin.com and only copy the link to the files here.
If you are able to do that, it would be much easier to follow other comments if you paste your files there and then edit your comments - thank you very much!

But now to your issue: I just started a fresh run of the provided script on a (nearly) clean install of Windows (German) and the build succeeded without errors.
Then I compared the output and also identified the already mentioned warning "MSB8065" to be the main difference. For some reason, it is not creating the "sndfile.def" in libsndfile which finally leads to error "LNK1104".

A Google search returned a similiar issue (reported at StackOverflow) when the manually set date of a computer was before the creation of the source files. So I did some tricks to verify that, but was only able to verify it with a date after 12th of September, because git refuses to connect to sites with invalid SSL certificates.
But even this completed successfully (all runs with 121 warnings).
So, I don't know how to continue from here...

@Giermann Great work. Thanks for confirming it can work! I agree with your error detection - that was the first I saw.

As far as I recall git doesn't preserve file timestamps on clone/fetch (a right pain). So as long as a --cleanall or otherwise deleting the source was was done , forcing the files to be re fetched they'd have to be dated before current clock time - unless there is a really weird clock thing happening. Perhaps if localisation of time format is different between Windows GUI and command line - clutching at a straw there. I'm also stuck I'm afraid.

I don't have installed EN language pack still. I will try it. I guess also this is the problem.

I'm sorry for my long text post. I just corrected this with pastbin.com

My issue is kind of weird. I will try the build on another computer (no EN language package also) and see what I 'll get.

I installed EN language pack and got same issue.

Did you already try on another computer?
Can you also try to change line 137 in the script and modify "-Daudacity_has_asio_support=On" to "-Daudacity_has_asio_support=Off"?
I'm pretty sure, the problem is related to the build in general, not ASIO specific.

If this also fails, it would be time to open an issue to get support from the Audacity team:

Another idea: the issue leading to MSB8065 seems to be compiler dependent.
You could try to use another version of Visual Studio, i.e. 2019 instead of 2022.

To do so, uninstall all components (Python, cmake, Visual Studio and its installer), reboot and try again with a fork of Steves script, which I modified to choose the VS version:
https://gist.github.com/Giermann/c3f88ee2a147f9a688a2ca76e1334a54
Set VISUALSTUDIO_REL in line 34 to either 2019 or 2017 and then start from scratch with "--install" and so on...

I updated to Audacity 3.4.0 and switched to using the "cmake" that comes with Visual Studio. This means the cmake-gui option is no longer available.

I also cleaned up the flow so the --install option no longer required a new cmd window to be opened .

Due to the number of issues with Audacity 3.4.0 this builds 3.3.3. If you want 3.4 then use "build-audacity.cmd -- install -v3.4"

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

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".

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.

I found a program installed called something like conan version manager I think it was installed by Visual studio, I uninstalled it and got further and now have another error.
