The Best Low Bit Rate Audio Compression Algorithm
Best Compressed Audio Format
The “best” audio format depends on your needs. To balance download speed and hard drive space against quality, this page looks to chronicle some of the tests that have been done around the Internet. While not all are up-to-date, they do provide a good swath of audio formats available.
As a result of these tests, this document assumes that Ogg Vorbis is the best so-far in audio compression, based on tests listed.

MP3 size-quality performance is among the worst but it's quality is still considered adequate.
Ogg Vorbis
A free audio compression technology and software growing quickly in use.

Many other services have been criticized for producing a great format and then sitting on it.

However, OGG may not be the best choice in every circumstance. For instance, it is not very good at encoding low-bitrate audio.

Ogg Vorbis can encode files at a wide variety of bitrates from sub-16kbps to 256kbps, and in stereo, mono, or 5.1 surround sound. This includes both Variable and Fixed Bitrate compression for streaming.
