Audio file requirements

Uploading to the audio library

Requirement	Value
Accepted formats	WAV, MP3, OGG, G.722
Maximum file size	50 MB
Sample rate, bit depth, channel count	Not validated on upload
Duplicate files	Deduplicated automatically — uploading the same file twice doesn’t create a copy

Recordings that Get2Dial makes of your calls (not uploads) are stored as WAV by default.
