Hello CAn you ppl please name a free software which plots the graph of pitch of sound from mic. Link appreciated Thanks
Four years before I used Cool Edit Pro......it was damn good....... You may use it............can't find the link now.....but it is available.
Free and open source, you might want to look at Audacity. I doubt that it is giving you the scale and graph that you are after, but it will at the very least give you the waveform to give you the idea of your audio spectrum. It might do what you are after, but from your exact post I can't say for certain.
