- Description
- Compressed audio file similar to an .MP3 file, but offers several performance improvements; examples include a higher coding efficiency for both stationary and transient signals, a simpler filterbank, and better handling of frequencies above 16 kHz; maintains quality nearly indistinguishable from the original audio source.
- 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.
