At this time we only accept WAV or AIF/AIFF audio files for ingestion*.
We do not currently accept mp3 or FLAC audio files.
WAV and AIF/AIFF requirements:
Sample Rate: 44,100 kHz Sample Size: 16 bit Bit Rate: 1411 kbps
*Our mp3s are then transcoded from this source file at 320 Kbps CBR (Constant Bit Rate) using a LAME encoder. 320 kbps is the highest possible bit rate setting a LAME encoded mp3 file can have, and this higher bit rate generally results in superior sound quality as well as a closer representation of the original sound.
