I have two "sources" of audio:
- record WAV audio files (44.1kHz, 16bit, stereo) with Linux arecord and convert them with LameMP3Encoder to MP3 files (44.1kHz, 320kbps, 32bit**, CBR)***
- record MP3 audio files (44.1kHz, 320kbps, 16bit, CBR) directly* using Darkice and LameMP3Encoder
No I need to calculate MFCCs of the same section in both sources. As I was told here, it is important for MFCCs to keep the same format throughout my workflow. Will the coefficients come out different for the two cases? And if so, how could I solve my issue?
*whatever Darkice is doing in the background
**I think this could be changed to 16bit if needed
***Does it change the WAV files when I open them with Adobe Audition don't modify anything but click 'Save As' and keep the format the same?
