- 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.
- A headerless file of IMA ADPCM audio data. IMA ADPCM claims 16-bit precision packed into only 4 bits, but in fact sounds no better than .vox.
