I am posting this under ‘Windows’ (rather than under the Audacity version specifically) because we’ve only had this problem since upgrading to Windows10. I can’t see it having already been reported anywhere else on the Forum so maybe it’s a new bug related to Win10 or how Audacity interacts with it?
We have been running Audacity 2.2.2 under Windows10.0/Pro/Build17134.345,x64,4GB RAM,3GHz,111GB freespace drive C. When the problem first occurred we were running version 2.0.5 (under the same Windows version) which is why we upgraded to 2.2.2. Prior to Win10 we did not have the problem at all on any earlier Audacity or Windows versions.
The problem: During recording we sometimes see ‘gaps’ in the audio (flat-lining), of one or more seconds, spread randomly through the track, with a message overlaid in an error-window “Recorded Audio Was Lost At The Labelled Locations. Possible Causes: other apps are competing with Audacity for processor time; or you’re saving to a slow external storage device”. The message then sits there (while the recording continues) until the user chooses to stop the recording.
No audio is actually being missed; if (after hitting Stop) you laboriously close the gaps up manually during editing (ie select the gap-section and delete), the sound is perfect; it is all there, the apparent audio ‘gaps’ are bogus. That’s why it seems to me to be a buffering delay or lag of some sort.
This PC is not on the internet or even a LAN, ie it is completely standalone. I have checked Task Manager on some of these occasions and all the readings have been low, nothing yellow-highlighted, and most times Audacity is the only user process running!
I replaced the entire PC with one having the same specs (ie the same Audacity/Windows versions) and we got the same problem.
The problem seems more prevalent when doing longer recordings (say 1-2 hours in duration) but we have had it on shorter recordings also. Another peculiarity is that we’ve experienced it far more often on music passages, as opposed to spoken passages.
I have not been able to pin down what brings this problem on. It is completely random and unpredictable. It might happen 3 times in 4 days (as at present), or we might be free of it for 3 weeks or more.
In a normal week, we would use Audacity up to 10 times daily, Mon-Fri, and it is also used to a lesser extent at weekends. So we are regular Audacity users and 95% of the time have no problems with it. Apart from this one random issue!
We have now upgraded this PC to version 2.3.0 and will wait and see. However, I have read the bug-fixes for the latest release and couldn’t see any mention of a problem like ours, so am not particularly optimistic.
Do you or anyone have any clues as to what might be causing this? Any suggestions on where to look or what to try next? I hope I’ve provided sufficient info above, and any assistance would be greatly appreciated.
