|Priority||normal||Severity||minor||Reproducibility||have not tried|
|Summary||0008406: Exporting a 1-second long audio region takes about 10 minutes|
|Description||While working around the problems I've reported elsewhere (https://mantis.ardour.org/view.php?id=8404), I've stumbled upon another issue.|
Exporting an audio region of about 1-second when there's no processing applied takes hundreds of times longer than it should.
I can make my sounds, but I can't deliver them to the client.
|Steps To Reproduce||1. Right click on an audio region|
2. Select "export"
3. Proceed to export the file
4. Wait until Ardour finishes
5. Realize it took forever.
I run in to this too, on Ardour 6.5 just downloaded from the ardour site, Debian stable, Xfce, Full version from about dialog: Ardour 6.5.0 "Old Land" (rev 6.5) 64-bit Intel.
(I do run into the same problem when using the older Ardour from the Debian repositories).
This is on Jack, with a Behringer U-Phoria UMC204HD. If you need more / other info that can help to solve this, feel free to ask.
||And just a little bit later I manage to export sound just fine. This newer version of Ardour have a rearranged Sound/MIDI-installation dialog (Sorry if I get the name wrong, I am translating from the Swedish user interface) - I believe I had the Device setting wrong, and when I set it to the UMC204HD 192k, the sound export started working just fine.|
1) Can you reproduce this without JACK (Menu > Window > Audio/MIDI Setup)?
2) Is it the export by itself that takes this long, or start/end of he export?
3) Could it be that the export target is a slow USB disk or thumbdrive?
@x42 - Changing from JACK to Alsa or Pulseaudio doesn't affect it, now it works just fine disregarding what is selected.
Unfortunately I cannot find the setting which causes the problem again - the export works just fine.
Most of the time the export just wrote 42 bytes to the file, and then simply paused. I experienced it as if it was completely stuck, but sometimes I managed to get a file that represented parts of the track in ardour, something like 1.4 MB, for a 18 sek clip.
For your question 3, the answer is no. When using ardour I have written the file to a M.2 SSD.
Earlier it would get stuck exactly as in the image unfa provided above ^.
