- 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.
- CVU file is a CVSD Unfiltered Audio. Continuously Variable Slope Delta modulation (unfiltered) is an alternative handler for CVSD that is unfiltered but can be used with any bit-rate.
