Maybe I shouldn’t be using NSConvertHostFloatToSwapped to get the sample data into an NSSwappedFloat format? 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.
