  • FLAC (.flac or .fla) is the Free Lossless Audio Codec, an open-source compression scheme that can cut the size of an audio file in half (on average) while not losing any quality in the process. It's basically ZIP for audio files. Using FLAC is good for Freesound because it saves on disk space and bandwidth usage, reduces download times, but doesn't degrade the quality of the sample like mp3 or another lossy codec would.

  • Ogg Vorbis (.ogg) is an open-source lossy audio codec comparable to modern AAC Audio (as used in the iTunes store, etc.). It does degrade the quality of the sample somewhat in order to save on space, but it is much more efficient at this than an older format like mp3. An Ogg file can have the same quality as an mp3 file using less space, or better quality using the same space.

In the language of the web, HTML (HTML5 is the latest version), MP3, Wav, and Ogg are supported. Here is a table of popular browsers and the supported format currently (this might change in the future).

 

The audio recording, conversion, and editing can be made with Audacity - multi-track audio editor and recorder for Windows, Mac OS X, GNU/Linux or Myna - online audio editor.
