|Target Version||3.X||Fixed in Version|
|Summary||0003179: add command line option for quick session exports|
|Description||wouldn't it be cool if one could export an ardour session without the need to open it (GUI and all) ?|
something like a command line would be cool:
ardour <session name> --export -- <export options> -o <some output file>
no GUI, no nothing, just an export. I reckon this could be tricky to implement if the session opening is very tied to the GUI initialization ... is this doable at all from the current ardour design ?

|its not tied to the GUI at all. adding this to ardour3 and forcing it to use an existing "export profile" would not be all that difficult.|
|sounds great Paul! the opposite would have surprised me :)|
|That would be very cool to have, because with commandline export we will be able to integrate Ardour with automated rendering tools, like Remake (https://github.com/morevnaproject/remake [^]) in animation production.|
Bump! I just wanted to request this feature, but I found this.
It would be very useful if Ardour could render a session without using any audio backend. I often face the problem that when exporting long sessions I can't do any audio work, becasue my JACK is muted and busy with Ardour's exporintg, also starting a new JACK client may interrrupt the exporting.
This would allow me to save my session, close Ardour GUI and export audio from commandline, and load another session and continue my work.
I guess it should obey export options, regions etc that are in the project. A way to override this would be nice, but in my idea - a secondary thing.
If JACK is the backend in use, then JACK must necessarily be involved in the export process (because data may come from other JACK clients). JACK being used for non-realtime export means that it cannot interact with the audio interface.
We do include a Dummy backend but do not expose it to users. This in theory could be used to do an export.

distro-builds or installations where it's in $PATH: ardour5-export
This has been around since Ardour 4.7. It doesn't have any fancy options (no export presets etc), but gets common export jobs done just fine.
I tend to keep all my Ardour sessions "self contained", so using the Dummy backend shouldn't break anything in that case.
I've tried out the ardour5-export tool. I get a "Cannot get samplerate from session" error, and when I pass "--samplerate 48000" as an argument - It shows me the help screen:
/opt/Ardour-5.10.0/bin/ardour5-export --samplerate 48000 "/unfa/Projects/Albums/DnB 03/Tracks/Anti-Feature/Anit-Feature vocals/" "Anti-Feature vocals 02.ardour"
ardour5-export - export an ardour session from the commandline.
( help text continues )
If I use the shorter option "-s 48000" I get error "invalid option":
/opt/Ardour-5.10.0/bin/ardour5-export -s 48000 "/unfa/Projects/Albums/DnB 03/Tracks/Anti-Feature/Anit-Feature vocals/" "Anti-Feature vocals 02.ardour"
/opt/Ardour-5.10.0/lib/ardour5-export: invalid option -- 's'
Using "--s" instead of "-s" yields no error message but I still only see the help text.
I tried again running from the Ardour session directory:
unfa@unfa-desktop /unfa/Projects/Albums/DnB 03/Tracks/Anti-Feature/Anit-Feature vocals $ /opt/Ardour-5.10.0/bin/ardour5-export "." "Anti-Feature vocals 02.ardour"
Cannot get samplerate from session.
I tried various combinations of parameters to no avail.
Also: is the session always exported as 16-bt WAV as the help screen says, or will it obey session's export settings? Being able to use 24 and 32-bit float precision would be great for further processing - for example batch exporting song mixes for mastering.
Usage: ardour5-export [ OPTIONS ] <session-dir> <session/snapshot-name>
The tool expects the session-name (no .ardour file-name suffix).
I tried relative and absolute paths, with no suffix and I still get the same error:
$ /opt/Ardour-5.10.0/bin/ardour5-export "/unfa/Projects/Albums/DnB 03/Tracks/Anti-Feature/Anti-Feature vocals" "Anti-Feature vocals 02"
Cannot get samplerate from session.
Am I doing something wrong?
Should I file another issue about this maybe?
|I've fixed the --samplerate option (5.10-467-gd98b722a2) and improved error-reporting and help-text (5.10-468-gbc713b00c)|
"Cannot get samplerate from session" likely means that the tool can't read or find the session-file.
I just tried with paths spaces and cannot reproduce the issue. Works fine, too here.
But /opt/Ardour-5.10.0/bin/ardour5-export is a shell exec wrapper using /bin/sh
maybe that is problematic? Does it work with a simple test session e.g.
