CVSD
Continuously Variable Slope Delta modulation
The CVSD extension identifies files commonly known as Continuously Variable Slope Delta modulation. 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.
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.
