Does anyone know where I can find a waveform component for mp3/wave files?

I prefer an open source component, but if you know a non-free component please tell me the official website. Does anyone know where I can find a waveform component for mp3/wave files?

I prefer an open source component to fix it as I want, but if you know a non-free component please tell me the official website to buy it. I don't have problem if this is in C# or in VB.
