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 ^. |
