FLAC stands for Free Lossless Audio Codec, an audio format similar to MP3, but lossless, meaning that audio is compressed in FLAC without any loss in quality. This is similar to how Zip works, except with FLAC you will get much better compression because it is designed specifically for audio, and you can play back compressed FLAC files in your favorite player just like you would an MP3 file.

FLAC stands out as the fastest and most widely supported lossless audio codec, and the only one that at once is non-proprietary, is unencumbered by patents, has an open-source reference implementation, has a well documented format and API, and has several other independent implementations.

WavPack is a completely open audio compression format providing lossless, high-quality lossy, and a unique hybrid compression mode. Although the technology is loosely based on previous versions of WavPack, the new version 4 format has been designed from the ground up to offer unparalleled performance and functionality.

In the default lossless mode WavPack acts just like a WinZip compressor for audio files. However, unlike MP3 or WMA encoding which can affect the sound quality, not a single bit of the original information is lost, so there's no chance of degradation. This makes lossless mode ideal for archiving audio material or any other situation where quality is paramount. The compression ratio depends on the source material, but generally is between 30% and 70%.

The hybrid mode provides all the advantages of lossless compression with an additional bonus. Instead of creating a single file, this mode creates both a relatively small, high-quality lossy file that can be used all by itself, and a "correction" file that (when combined with the lossy file) provides full lossless restoration. For some users this means never having to choose between lossless and lossy compression!

WavPack employs only well known, public domain techniques (i.e., linear prediction with LMS adaptation, Elias and Golomb codes) in its implementation. Methods and algorithms that have ever been patented (e.g., arithmetic coding, LZW compression) are specifically avoided. This ensures that WavPack encoders and decoders will remain open and royalty-free.

 WavPack is free software, but if you find WavPack useful please consider making a donation to help support past and future development.

Monkey’s Audio

Download Monkey’s Audio

Description
Monkey’s Audio is a fast and easy way to compress digital music. Unlike traditional methods such as mp3, ogg, or wma that permanently discard quality to save space, Monkey’s Audio only makes perfect, bit-for-bit copies of your music. That means it always sounds perfect – exactly the same as the original. Even though the sound is perfect, it still saves a lot of space (think of it as a beefed-up Winzip™ your music). The other great thing is that you can always decompress your Monkey's Audio files back to the exact, original files. That way, you'll never have to recopy your CD collection to switch formats, and you'll always be able to perfectly recreate the original music CD.

Features

•Efficient (fast and great compression) — Monkey's Audio is highly optimized and highly efficient

•Perfect sound — absolutely no quality loss, meaning it sounds perfect and decompresses perfect (it's lossless!)

•Media Center™, Foobar™, WMP™, Winamp™, and more support — supported by most popular players and rippers

•Easy — the Windows environment interface is both powerful and easy to use

•Free — Monkey’s Audio is completely free!

•Error detection — Monkey’s Audio incorporates redundant CRC’s to ensure proper decompression of data (errors never go unnoticed)

•Tagging support — Monkey’s Audio uses its own extremely flexible APE Tags so you can easily manage and catalogue your Monkey’s Audio collection

•External coder support — you can use Monkey's Audio as a front-end for all of your encoding needs

•Freely available source code, simple SDK and non-restrictive licensing — other developers can easily use Monkey's Audio in their own programs, and there are no restrictive licensing agreements
