 //When choosing your format keep in mind that our engine automatically runs the files through a compression µ-law algorithm. This means that all files will be down sampled to an 8-bit 8kHz. If you were to encode the files in a lower quality you would find the audio files you use would end up sounding better than your initial compression.// ​ //When choosing your format keep in mind that our engine automatically runs the files through a compression µ-law algorithm.

-There are three audio formats for development that are always recommended:​ 
-  * 8 kHz 16-bit linear PCM WAV 
-  * 8 kHz 8-bit µ-law WAV 
-  * 32 kbps 16khz MP3 (anything larger is overkill) 
-  * **(all audio files must be mono not stereo)**
