Acidizer

Acidizer is an add-on tool for users of the Sonic Foundry ACID suite. It is used to add extra information to wave audio files so that ACID will automatically recognize the file as a one-shot, a loop, or a disk-based audio file.

It also aids ACID in knowing how to accurately pitch-shift or time-stretch a wave file.
If you use lots of wave files with ACID, changing each file separately can be a real pain. Acidizer allows you to make changes to these settings just as easily as using Windows Explorer. Drag and drop individual files, or whole directories at a time!! You'll be done in seconds - time you can spend perfecting your ACID creations.
