Sound Activated Recording fails when recording meter disabled
Last modified: 2021-01-28 15:15:47 UTC
If the recording meter is disabled (neither the separate recording or combined meter are enabled), then Sound Activated Recording does not automatically pause when input is below threshold. Reported on Windows and repeatable on Linux, so assumed to be all platforms.
(In reply to Steve Daulton from comment #0) Regression on 2.0.6 where Sound Activated Recording did not require a displayed Meter Toolbar to work. I suppose it scrapes a P3 then. On my machines (Windows, Mac, Linux) if there is no input meter then Sound Activation Level is disregarded so that even at 0 dB threshold, signals below 0 dB are recorded "as is" (not as silence which the report http://forum.audacityteam.org/viewtopic.php?p=322539#p322539 seems to imply).
*** STEPS ADDED ***
Fixed in: https://github.com/audacity/audacity/commit/f509d9c SAR is no longer coupled to the input meter.
Testing on W10 with Audacity 3.0.0 4e6e3c2 This still does not work With both meters disabled and regardless of the setting of the Sound Activation Level (including either extreme 0 and -160 (and the default -30) and with the SAR flag set "on" - Recording appears to ignore SAR sound level completely and just continuously records.

It's working just fine here. I've disabled both meter toolbars, have my level set to -30 and it doesn't record anything until I feed it some sound through the microphone.
It even works for me when running Catalina in a virtual machine. Recording stops when the sound drops below the threshold. What am I doing wrong???
Testing on W10 with Audacity 3.0.0 4b07fba This now works for me 1) I set the threshold t0 -21dB 2) tested SAR with both meters active 3) Observe SAR works only recording loud sounds 4) hid both meter toolbars 5) Observe SAR works only recording loud sounds So I don't know what was happening yesterday :-//
Testing on macOS 11.1 Big Sur with Audacity 3.0.0 4b07fba This now works for me 1) I set the threshold t0 -21dB 2) tested SAR with both meters active 3) Observe SAR works only recording loud sounds 4) hid both meter toolbars 5) Observe SAR works only recording loud sounds
Examining the commit for this fix shows that it is not platform-dependent https://bugzilla.audacityteam.org/show_bug.cgi?id=2639 And as this tests OK on W1- and Mac I shall close this as FIXED
