Look what I made! PCM-MCU-C Version 3.0 (SF2 support)! - Python utility for converting audio files to: .h .pcm .spack

https://github.com/Mejolov24/PCM-MCU-C/releases/tag/3.0

Ever wanted to play audio on your arduino embedded proyect using a .h file, but the converters require too many steps?
well, not anymore.
My python utility handles everything for you using ffmpeg-python and numpy, allowing for in place conversion, drop your audio at /input and get it at /output, you can tweak the bit depth, sample rate and padding for .spack files!

With the release of V3.0 of PCM-MCU-C, the app is much more stable due to the usage of my new libary: MenuCLI, and also with the adition of converting .sf2 files directly.
