Recording Speed for IVR Audio files

[LarryHudsonVO]

I am a voiceover artist and do IVR recordings for clients. Is there a "standard" recording speed (i.e. 44100Hz) and bit rate (i.e. 24-bit) to record at for IVR systems or is it specific to certain manufacturers? Thanks in advance for the answer! LH

Hi Larry,

For our platform, specifically, the audio recordings we support are of the following format:
(more details can be found at: http://www.plumvoice.com/docs/dev/devel ... ence:audio)

8 kHz 16-bit linear PCM headerless (*.l16)
8 kHz 8-bit µ-law encoded headerless (*.ul)
8 kHz 8-bit a-law encoded headerless (*.al)
8 kHz 16-bit linear PCM WAV (*.wav)
8 kHz 8-bit µ-law WAV (*.wav)
8 kHz 8-bit a-law WAV (*.wav)
MP3 (*.mp3) - Note: If the audio file is poorly encoded, the mp3 will not work.

However, this is specifically our standard and we cannot say for sure what other manufacturers might or might not support.

Regards,
Plum Support
