Re: SOFTWARE for adjusting speed/pitch ???

Unfortunately, Audacity is not good at speed adjustment. Here's a sample GIF of a simple sine wave (above) and the same wave file after speeding up 10% with Audacity (below). As you can see, the sped-up version has some additional noise.

It's a simple test, so you can test your wave editing program by yourself. Just generate a small file with sine wave, change the speed, and do the before-and-after comparison with the frequency analysis feature.
