Re: .AIF file import clipping

Steve, Good Info~! I am beginning to think that there might be several things happening with this audio. Attached is a small fragment that shows waveform peaks getting chopped at +/- 1.0, exported as an .aiff 32-bit float. If you zoom out to /- 2.0 the clipping is obvious. The A/D is performed on th...

I'll check how the .aif files were recorded and let you know what the bit format is. I am concerned that if Audacity does not allow levels over 0dB during a file import, then the utility of Audacity is inherently limited in some real world situations. Here's my application, and why peak levels will ...

.AIF file import clipping

When importing .aif files (recorded on a Mac), Audacity seems to be chopping off all portions of waveforms that exceed +/- 1.0. When I right click the scale to view an imported track at +/- 2.0, the waveform of the entire imported is definitely getting chopped off exactly at +/-1.0, evidently gettin...

In Audacity Edit->Preferences my choices for recoding devices are: - HDA ATI SB: ALC268 Analog (hw:0,0) - pulse - default None of these appear to be seeing or proc...
