Bye-bye! MP3!

Anida is an audio codec and audio compression format developed by Sevenuc Consulting. It was designed to reduce audio data size to reduce transfer time and save disk space. The Anida engine is designed as a KAM (Kilobytes Audio Machine) for deeply embedded small devices and has a small memory footprint, it promised to compress common music files with kilobytes as opposed to megabytes.

Why Anida?

  • Save storage space. Saving huge number of storage space is especially important for large music sharing sites. It also very important for the end users, who will never be happy if the big music files disappear forever and the phone storage released?
