It happens with any sound file (ogg, wav, flac) with a different samplerate. I simply tired to open various files in /usr/share/sounds, most of them are at different samplerates than my Jack setup of 44100Hz. Although I have not looked at the code, when I heard about the automatic resample-on-import feature I was skeptical: As far as I recall we do not store whole waves in memory. (Nor should we.) So I was wondering how the resampling feature was even possible? Where is the new wave being stored? In memory, or a new file? If it's a file, well OK. Although there may be issues with that as well, as I mentioned some time ago. (Where to store them, folders etc.) ----- A quick note also: There is code in MusE that I think would be essentially ready to go, with reexamination and so on, that does automatic resampling on-the-fly using SRC. The code was last tested years ago and working fine! The thing is, I had to disable it at the time because of a MusE flaw: We were using shared event lists. This made my efforts come to a screeching halt, because we cannot use shared soundfile handles! But then Florian added non-shared event lists. I helped finish that work. It means the door is now open for me to try that resampling code again. Yes, it /can/ work now! An immediate benefit of the non-shared event lists was this: Wave events that point to the same /compressed/ sound file can now be played even if they overlap. This was not possible before and had nasty results like severe denormal chugging which ground MusE to a halt. The problem was that our wave events wanted to keep switching the single shared soundfile position back and forth among the various events, which is a no-no, compressed files need to 'progress' naturally without being told to jump around like that, and the same with pitch/time shifters. So you see, non-shared event lists cured all that. It was a huge undertaking. But Florian took resampling /much/ farther in his branch (that I mentioned recently) - he added beat matching, pitch shifting, time stretching etc. So although I can try to resurrect my resampling code, I must also keep in mind the possibility of merging some of Florian's work, and how it might fit in. IIRC It is radically different in that it uses something he called 'extended ticks'. My primary goal with my code was for resampling of imported audio files. But the work was a good learning and starting point for pitch shifting, time stretching and so on, and I tried to keep the architecture open for that eventuality.
