Hi,
first of all, I know that it looks like an Ardour-specific question, but
it's not. Not fully, at least :-)
I'd like to publish the music I make not only in MP3, but also in a way
that anyone can download and modify it at will. Ideally, there would be some
kind of "bundle export" in Ardour that I could use to create an archive that
included all the audio files and the metadata of the project. But I've
searched and didn't find anything similar. Does it exist?
And if it doesn't, what could I use as a substitute? I figured I could
export all the audio in FLAC, and I could share the Hydrogen file for the
drums, but what about the effects, and the automation? I don't think the
"Right Way" is to export audio with effects applied, because (IMHO) part of
the fun is applying effects that weren't in the original mix. But I'm a
complete newbie in this field, and I don't know if it's how people usually
do it.
Thanks in advance.

Couldn't you just tar the ardour project directory and export hydrogen bank?

Well, what I did was to make sure there was no or little unused audio
left in the session, bounced parts with not-so-common effects, wavpacked
the audio files and put them along with the session folder in a tarball.
FLAC doesn't work with float-format, but wavpack does, so you have an
entirely losless option.
Here wavpacking turned 184.5 MB into 75.8:

That's a good question. I don't know, because last time I looked into
it, the project directory had a lot of things. I could try, anyway. Thanks
for the hint.

it has everything needed to fully recreate the session in another
instance of ardour. the "interchange" subtree has all the actual data
files, but does not contain the session file that actually describes
how to arrange the data to recreate the session or the peak data used
to draw waveforms.
what you're actually looking for is "stem export" which is not
easily/simply available in ardour2, but is available (though not very
tested) in a3. it will automatically produce a set of audio files, all
the same length, 1 per track, of either the entire session or some
specified range within it.

Hell yes, time to start looking at a3, a project I have planned for
this fall will greatly benefit from this functionality.

a while ago, i created ardour demo sessions for the openDAW project, and
i was looking for a way to let people play with pretty much everything
except the edits. so i created a full copy of my ardour session
directory, used ardour2's "consolidate" feature to bounce all the messy
edits into one single region per track, then got rid of all older
snapshots. now i could clean up unused sources, and hey presto: a nice
and concise session that gives a user maximum leeway in fiddling around.
if you want to play:
http://stackingdwarves.net/TIH.tar (guitar and saxophone duo)
http://stackingdwarves.net/MFV.tar (cheesy jazz sextet standard)
both are mixing to third-order ambisonics and use an UHJ encoder for
stereo downmixing.
i abused ardour's session directory a bit, in that i added some session
photos and copied all external config files in there as well (mainly for
jconvolver), so that it contains pretty much everything you need to hear
what i was hearing. there's also a shell script that probably won't work
on most people's systems, but gives you an idea what programs i was
using in addition to ardour2.

They are amazing sessions! Outstanding work on all accounts. Cheesy

BTW, This was the first ardour-session that I've seen with nicely
written comments on _every_ track/bus. Don't miss those - bottom of
ardour's mixer-strip.
@JACK-devs: please load these sessions and experience first hand that
port-creation/connection is waaaay too slow. For example loading the MFV
session ~ 500 JACK ports with jackdmp/dbus 1.9.8 takes >30 seconds here!

Thanks for making these available ! They provide excellent use
cases for the AMB mixer that's slowly taking shape.
I've got a strange problem with MFV. *Something* is poisoning
the signal graph with Nans or Infs. One visible result is that
e.g. the W channel of one of the jkmeters shows only peaks and
no RMS values (this is to be expected if the filter state gets
a Nan - once a Nan always a Nan). The other indication is that
adding an Ambdec produces a never ending xrun storm even if the
effective CPU load remains below 10%.
Have you seen anything similar ?

Second, the AMMD is thinking about a new (as far as we know) of
net-album concept, which would include such things like sharing ardour
files (and making re-appropriation easy). We called that audioGIT, it's
really a debut project, by now, we're making proofs of concept, and are
trying to think the better way to achieve this. You can read more (in
French) about this here[2]. Any help appreciated, any contribution is
welcome, and so on, just write us (orl(a)ammd.net).

Turned out to be jconvolver. Added some Nan testing code to zita-convolver
and the problem disappeared, also without the extra code. Could be I
accidentally installed a version compiled on another machine. But then
it's a miracle non of this showed up earlier...

thanks. yeah, flügelhorn is really like a hello kitty pillowcase for the
soul ;-P
it's to the trumpet what the double-bass is to the electric bass guitar
- the restrained, subtle version. you can't noodle around easily, you
have to mean it (says an electric bass player).
