| """ Deep Auto-Encoder implementation | |
| An auto-encoder works as follows: | |
| Data of dimension k is reduced to a lower dimension j using a matrix multiplication: | |
| softmax(W*x + b) = x' | |
| where W is matrix from R^k --> R^j | |
| A reconstruction matrix W' maps back from R^j --> R^k |

Minimal example: transcode from MP3 to WMA:
ffmpeg -i input.mp3 output.wma
You can get the list of supported formats with:
ffmpeg -formats
Convert WAV to MP3, mix down to mono (use 1 audio channel), set bit rate to 64 kbps and sample rate to 22050 Hz:

| Compiling MEX function including RtAudio for audio mauipulation (Toy example) | |
| Tested on: | |
| - macOS Catalina 10.15 | |
| - Matlab R2019b (XCode clang++) | |
| - RtAudio v5.1.0 | |
| To use this .cpp file to compile mex function, you need to download RtAudio first | |
| (See https://www.music.mcgill.ca/~gary/rtaudio/). |
