Both YouTube and MP3 encoding involve "lossy" (inexact) encoding. The encoded waveform is an approximation of the input signal, but one of the things that is ignored (because it's not audible) is the relative phase of frequency components. Changing the phase of some frequencies in a wavefo...

Previous versions of Audacity ignored MP3 errors, but that could cause worse problems down the line (such as projects crashing and destroying hours of work). Audacity now catches the problems on import before they do any damage.

I just hope the configuration stays between restarts It should. I am not sure if it is possible to detect this issue Unfortunately Audacity cannot detect that, because it happens in PulseAudio before Audacity. Audacity just interfaces with PulseAudio, but has no idea what happens on the other side ...

I suspect that the problem is that you've made a "data CD" rather than an "audio CD". An "audio CD" is similar to a music CD that you might buy, and are playable on most CD players. A "Data CD" contains files (any sort of file, not just audio files). Some CD p...

The error message means that the MP3 file has an unrecoverable error in the header.
