- 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.
- OGA is an audio file format that can be created using various compression algorithms such as Ogg FLAC, Ghost, and Ogg PCM. Ogg Vorbis or Speex compression can also be used but it is not recommended by Xiph.Org.
