- Description
- A lossy file format used to compress speech in Global Standard for Mobile (GSM) telecommunications. It is very effective for reducing audio file size. However, encoding and decoding audio signals severally is discouraged as the final product will have a lot of noise. Popular with some voice mail software but it is CPU intensive.
- Audio file encoded in Dialogic's ADPCM (VOX) format, a format used for saving human speech audio; saves digitized voice data sampled at a low rate; enables the audio data size to be small while still maintaining clarity; used by computer telephony systems.
