SPH

SPeech HEader Resources

The SPH extension identifies files commonly known as SPeech HEader Resources. 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.

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.
