Hi,
I'm writing on the off-chance that someone else has encountered this
problem or has an inkling of how it could be solved.
I have a Mac Mini and would like to use the line-in jack to perform some
very simple voice recording. When enabling Line monitoring in alsamixer,
I can hear the input fine, but no amount of fiddling with arecord has
yet enabled me to capture any audio. There are three subdevices, and I
have all set them to line input with capture switch to true. Then, I've done
$ arecord -D hw:0,[0-2] -f cd test[0-2].wav
...but to no avail.
It's not of deadly importance, but it does drive me crazy that I can
monitor the input and yet not capture it.
Any ideas?
Cheers,
S.M.
Hi all,
Standing on the shoulders of giants[*], I am pleased to announce the
public release of IR, a convolution reverb in the LV2 plugin format.
Released as free software under the GNU GPL, this easy to use plugin
has been created to open the fascinating world of convolution reverb
to Linux-based audio engineers. If you use Ardour to create, mix &
produce music, you will most probably want to check out this plugin.
Assorted features:
* Zero-latency operation
* Support for mono, stereo and 'True Stereo' (4-channel) impulses
* Realtime operation
* Very reasonable CPU consumption
* Maximum impulse length: 1M samples (~22 seconds @ 48kHz)
* Loads a large number of audio file formats
* High quality sample rate conversion of impulse responses
* Stretch control (via high quality SRC in one step integrated with
impulse loading)
* Pre-delay control (0-2000 ms)
* Stereo width control of input signal & impulse response (0-150%)
* Envelope alteration with immediate visual feedback: Attack
time/percent, Envelope, Length
* Reverse impulse response
* Autogain: change impulses without having to adjust 'Wet gain'
* Impulse response visualization (linear/logarithmic scale, peak & RMS)
* Easy interface for fast browsing and loading impulse responses
IR should work on Linux with Ardour 2.8.x (x >= 11) and 3.
For further info and source code download, please visit the plugin's
homepage: http://factorial.hu/plugins/lv2/ir
Thanks,
Tom

Hi you all,
what do you think about that? Have you got some personal experience?

Thanks for noticing this, I could reproduce the issue (and will fix it ASAP).
I also received some important advice from Fons offlist, regarding the
usage of zita-convolver that is especially relevant when running on a
multiprocessing machine. In that case the code may leak large amounts
of memory on reinitialising the convolution engine (every time you
load an impulse, or change a parameter). I haven't had a chance to
check this, so please be aware of this possibility. I know how to fix
it (thanks to Fons) and will do so very soon.
So please stay tuned for an updated, corrected version, should come in
a few days (I have to get a multicore system for testing and set it up)...
Thank you all for the patience and the nice comments,
Tom
Hi!
I am trying to send OSC messages to ardour by means of send_osc,
included in debian/ubuntu package pyliblo-tools
(http://das.nasophon.de/pyliblo/) .
I always get the message "liblo.AddressError: address error: invalid
URL" unless I am in the same computer that runs ardour and just enter
the UDP port number that ardour uses to receive OSC messages.
For example, this works:
send_osc 3819 /ardour/access_action Common/About
However, from my other computer in the same network, this:
send_osc 192.168.0.192:3819 /ardour/access_action Common/About
results in:
liblo.AddressError: address error: invalid URL '192.168.0.192:3819'
I have tried other options to no avail and the man page and pyliblo
examples didn't help me.
What is the right syntax in pyliblo outside the localhost for a given
UDP port?
Thanks in advance, Pablo

it seems to be working now.
i got another crash when trying to remove the plugin with
shift+rightclick in the ardour editor window, but i cannot reproduce it
for now.
i ll let you know, if i found out some other troubles.

I've tested ardour2 and ardour3. What happens is that I save the
session with one track, and when I close ardour and open it again, the
track is connected to more inputs and outputs then it was when I've hit
save. I use jackdbus + M-Audio Delta 1010LT. Is there any other info I
should give? Thanx!
minimal background: I went to college when I was 18, and in my youth
and stupidity, wasted the opportunity. I went to work in the IT field
and have done reasonably well, but the 8 - 5 corporate grind is
destroying my soul. I'm now 35 and have a family.
is there such a thing as electronic music-related degrees (undergrad)
in the US? or, are there composition degrees that primarily focus on
electronic methods? I'm considering going back to school, and I would
like to investigate this possibility, if it exists.
sorry for the off-topic post.
thanks,
Josh
