FS#12692 - Recording - positive clipping wraps around to negative or zero values
On my Sansa Clip+ 4GB, with Rockbox v3.11.2
Recording a wav file through internal microphone. If the audio signal clips at the positive limit, bad things happen:
1) Most of the time the recorded signal wraps around to a full scale negative value, which makes it sound terrible.
2) Sometimes the recorded signal wraps around to a near zero value, which still makes it sound terrible but the distortion is not so loud
3) Clipping at the negative end of the range is as you would expect - a flat line which sounds like normal digital distortion, as you would expect
See attached picture of the recorded waveform showing each of the 3 situations described above.
