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. | ||||

Minimal reproduction project. |

I've also reported this to Paul on Discord: https://discord.com/channels/344542072855986178/727813815454138408/1110258129410723850 |

Can you elaborate which settings you use to export? I have just tested this and cannot reproduces this |
|
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 7.4.2.117 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)? |
