mp3 files

Here's a short but excellent introduction, written by Sidney Wood, into the mp3 digital audio compression format. If you're not familiar with what mp3 does to your recordings and to your ears, you should read this intro first. For presentations of sound files on the internet it may at times be necessary to compress the original sound file to save storage space and/or avoid long loading times. Once you've converted a high-quality recording into the mp3-format, you should try to avoid re-encoding it if and when you change the volume or cut and paste it.

MP3directcut claims to allow mp3 files to be manipulated without a further quality loss due to re-encoding. I haven't tested this (and I don't get any royalties for writing about the product). Here's the link to the software, which is free.
