Any ideas on achieving correct results?
If they sound OK, except for the pitch, then you have one of two problems: 1… you've mishandled the sample rate somewhere. It’s recorded at 44100 and you’re playing back at 22050, or something similar. 2… you’re duplicating samples somewhere, reading one sample and turning it into two samples of playback. ---------------------------------------------------------------- Steve Bird Culverson Software - Elegant software that is a pleasure to use. www.Culverson.com (toll free) 1-877-676-8175 _______________________________________________ Do not post admin requests to the list.
