playing a tone continuously and changing its frequency

Mar 17, 2011 at 12:27 PM


I'm trying to play a tone and change its frequency in realtime. For generating the tone I used the Sine Wave Tutorial but changing the frequency while the tone is playing leads to a clipping. Can someone explain this?

Is there a possibility to playback a wav or midi file and changing the pitch in realtime?

Thanks in advance,

it is possible, but you'd have to write the code to do it yourself. NAudio doesn't have a built-in pitch shifting algorithm.
