VOX

A headerless file of Dialogic/OKI ADPCM audio data

The VOX extension identifies files commonly known as A headerless file of Dialogic/OKI ADPCM audio data. It carries low-level audio samples with limited container information, so software may need the correct sample rate, bit depth, or codec assumptions. Audio utilities use those settings to interpret, play, or convert the data correctly.

AMR

Adaptive Multi Rate

The AMR extension identifies files commonly known as Adaptive Multi Rate. It is designed for speech, voice recording, communication, or related audio exchange. Players and conversion tools can decode the sound when the expected codec and stream parameters are available.
