Do you know any good commertial or free audio / sound components that can be used in Silverlight (better on the client)?
Desired features:
visualizing (waveform, peakform etc., zoom, editing volume, pan, start and end markers etc.)
editing (channels: volume, pan, mute, fading, etc., merge, cut, copy, paste, etc., effects)
mixing different sound tracks, creating a downmix
exporting result in some in Silverlight usable (compressed) formats
Some useful projects that I've founded:
Saluse MediaKit for Silverlight (MP3 decoder, AudioPreProcessor, visualizers, effects)
Microsoft Design Toolbox sound mixer (incl. source code and video) and Demo
