Just found a nice audio compressor called Monkeys Audio (http://www.monkeysaudio.com). It has a plugin to allow playback with Winamp and other players and sounds absolutely awesome! The compression isn't as great as with MP3 but the quality more than makes up for it and besides big HD's are pretty cheap nowadays.


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!)
Winamp™, Media Jukebox™, and more support – supported by many 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 it's 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 evil restrictive licensing agreements


Description:

Monkey’s Audio is a fast and easy way to compress digital music. Unlike traditional methods such as mp3, ogg, or lqt 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™ for 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 recreate the original music CD if something ever happens to yours.

great for home collections off your cds, but downloaders wont care for it. whats the compression?

mp3 can be estimated at 128 for about 1 meg a minute. (most ppl use 192 or 160 though)

You're right Azz....the compression ratio is approx 60% of the original .wav so is not exactly ideal for anything other than personal music collections. Large HD's are cheap enough now anyway (I noticed a 340Gb IDE drive somewhere the other day). The sound quality is far superior to MP3...obvious really as it is a bit for bit copy of the original.

I am just waiting for my new soundcard to be delivered (an ESI-Pro Waveterminal 192X (http://www.esi-pro.com/esi-pro/eng/product/wt192x/wt192x.html) with digital I/O board) which should make it sound even better than with my crappy Live 5.1.
