The FAAC project includes the AAC encoder FAAC and decoder FAAD2. It supports several MPEG-4 object types (LC, Main, LTP, HE AAC, PS) and file formats (ADTS AAC, raw AAC, MP4), multichannel and gapless en/decoding as well as MP4 metadata tags. The codecs are compatible with standard-compliant audio applications using one or more of these profiles.
The Music Control Center can help you organize your existing sound file collection and walk you through the process of ripping backup copies of your CDs, moving the newly-created sound files to the correct location, and updating the database appropriately. It allows you to create playlists on-the-fly, save them, and load them for playback at a later date. You can search your collection by artist, album title, label, producer, song title, and year released.
The True Audio (TTA) codec is a simple realtime lossless audio compressor. It performs lossless compression on multichannel 8, 16, and 24 bit data of Wav audio files. The compression ratios depend on the type of music file being compressed, but the compression size will generally range between 30%-70% of the original. TTA supports both ID3v1 and ID3v2 information tags.
