Hi, I just discovered a bug in audacity versions 2.4.0 then 2.4.1, when I open an old project, whether it was created on version 2.3.3 or older, the tracks all appear flat or saturated even if the sound is present and normal. To display the tracks with the waveform I have to change the format, which is originally 16 bits PCM to 24 bits PCM, at that moment the waveform reappears, then go back to 16 bits PCM which is my default sampling format,and I have to do this on each of my tracks, then I have to save the project so that when I open it again the waveform appears normal in all the tracks…
Do any of you have the same problem and if so, how did you fix it?
I’m running Mac OS Mojave 10.14.6 MacBook Pro (15-inch, 2018) with Audacity 2.4.1
2.6 GHz intel core i7
32 GB 2400 MHz DDR4
We’re aware of that bug and are working on it.
change the format, which is originally 16 bits PCM to 24 bits PCM, at that moment the waveform reappears, then go back to 16 bits PCM
That’s a clever workaround.
Another workaround is to select each track and do Effect > Amplify with “Amplification (dB)” set to 0.0 dB.
Both methods cause the waveform to be completely recalculated, and new .au files created in the proper format.
Were these old projects created on a Power-PC Mac? I ask because we’re trying to track this down. This happened to me with some very old projects (2011 and earlier) that were probably created on my G5.
Thanks for the reactivity, yes it happens whether it’s with recent projects created on Macbook Pro or with my old projects created on Powerbook G4…
So I tried it your way and it’s really the fastest and therefore the easiest way to do it when you have multiple tracks in a project because with few gestures the problem is solved… thank you very much.
