... the glitch after filtering. A 20Hz high-pass filter may "help" with an asymmetrical too but it won't change the sound. An asymmetrical waveform can be normal and it can sound normal or it could be an indication of distortion. ...

... offset algorithm and some algorithms can make it worse if you have an asymmetrical waveform. DC offset is normally the result of a hardware defect so you're more like to see ...

... (Offset is usually cased by a "cheap" soundcard.) If you simply have an asymmetrical waveform a High-pass filter will help to even it out. You can choose a cut-off frequency of ...

... a constant offset. It's different at the beginning and end. Plus the waveform is asymmetrical (similar to a DC offset). Instead of offset removal, try a 20Hz high-pass filter. ...

An asymmetrical waveform is not necessarily a problem. It's "unusual" for an audiobook. I have a mono audio book where the playback ...

... red parts are digital clipping. (You recorded too hot.) Some sounds are asymmetrical (the positive & negative halves of the waveform are different) so it can be normal but what you have is probably caused by a "cheap ...
