this class allows you to load audio-files (wav,aif,mp3 at the moment) and check their attributes like sample-frequency, resolution, channels, length, format, compression, id3-tags and more. besides this it visualizes audio-samples they way you know it from waveLab, CoolEdit or any other audio-editor. find the complete package & feedback area at:
