|Summary||0009343: Export silence trim applies unwanted noise gating|
|Description||Noise trimming results in exports being noise-gated, poking holes in the audio.|
This can be seen as black bars on the export analysis spectrogram.
|Steps To Reproduce||I'm attaching a test project.|
Open it and export the session with silence trimming enabled.
You should see a striped spectrogram - with chunks of the audio missing.
Now disabled silence trimming and try again - the black bars will be gone.
|Tags||audio, export, silence, Trim|
||Minimal reproduction project.|
I've also reported this to Paul on Discord:
Can you elaborate which settings you use to export?
I have just tested this and cannot reproduces this
silence-trim-spektrum.png (262,225 bytes)
||The only difference I see is that I selected Shaped Noise dither, and you have no dither selected here. I'll try with no dither on my side.|
I've tested with no dithering and I have the same (gated) result. Could you test on Windows?
Maybe this is caused by some dependency misbehaving on Windows, while working as expected on Linux?
I could provide you with remote access to my Windows machine (via RustDesk) for debugging, if that'd be useful.
||Here's an export from official 22.214.171.124 Windows 64-bit build with NO dithering:|
||*7.4.117 (I typed some nonsense version number above, sorry)|
I just tested this on Windows 11 (at Harrison), and cannot reproduce this there either.
I also cannot see how silence trim would cut out something in the middle. Can you double-check that disabling that option exports correctly?
BTW, have you edited %localappdata%\Ardour7\config and changed
Option name="export-silence-threshold" value="-90"
While the backend should not matter, the data track -> master is still passed via the backend.
I have checked with both Dummy, and Portaudio/ASIO to be certain.
I've also re-imported the exported file and verified the loudness (Region > Loudness Analysis) and checked level with the "internal edit tool" to be within -67 and -57 dBFS.
This is mysterious..
Could you try with a different user (new preferences)?
