Compared to MixPad Multitrack Recording Software, Audacity supports various file formats, including OGG, FLAC, MP3, WAV, AIFF, MP2, and more. I am using Jupiterlab on Sagemaker for the runtime environment. I generated the files using Audacity and I saved the track to mp3 or wav.īelow is the code. I managed to implement an algorithm that can generate pictures passing files encoded mp3 or wav.Īt high level everything seems to work ok for Wav files but for mp3 I seem to generate a picture where the spectrum is faint (compared to the one generated by the wav file). You can open a WAV file as raw data and everything will be OK if know the format/parameters, except you’ll get a little glitch in. If it’s not audio it’s usually going to sound like random noise. I couldn’t find specific examples on internet and I attempted to put together a solution myself. If so you can use File Import Raw Data but you have to know (or guess) the bit depth, sample rate, and a few more parameters. I am trying to generate pictures from audio spectrogram.
