One of the great challenges for us working with audio is communicating ideas with words. It just leads to so much confusion, partly because music expresses emotions beyond words, but also because we struggle to describe specific points in the music.
Soundcloud.com is a cool new web service for anyone dealing with audio. You really have to sign up and play around with it to get a feel for what it is! As well as being able to upload large audio files and share them, you can attach comments to the wave form. It won’t embed here, but try looking at it on the soundcloud website.
Roll your cursor over the little avatars under the waveform to see comments, attached to specific points in the music.
