- 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 compressed with the Free Lossless True Audio codec (TTA); supports compression of multichannel 8, 16, and 24-bit .WAV data; compresses the original audio data with compression ratios of 30-70 percent.
