Hello all,
LAC2011 is due to start in a few days !
Anyone else staying at the Kilcar B&B ?
I'll arrive thursday at around 18:00 - will there be the
traditional pre-conference pizza gathering ? (or Irish
beers, or some stronger liquids) ?
Ciao,

Thank you coders :)
now I can use Linux to make music :).
Regarding to 'nobody does report success, just bugs are reported' I guess NO MIDI JITTER is worth a crossposting.
$ uname -a
Linux edubuntu 2.6.33.9-rt31 #1 SMP PREEMPT RT Tue Apr 26 15:05:31 CEST 2011 i686 GNU/Linux
jackd 1.9.8 I guess svn 4290 or earlier
Qtractor 0.4.8.69 svn 1978
Ardour2 1:2.8.11-1ubuntu1
a2jmidi_bridge 6-0ubuntu3
jackd --sync -Xalsarawmidi -dalsa -r48000 -p256
snd-hrtimer loaded and used as ALSA seq timer source, unfortunately there aren't enough timers to be used with JACK clients, when using the "-c" switch.
With Ardour (synced to Qtractor by JACK transport) I recorded
- Yoshimi, JACK MIDI
- Hydrogen (as sample player only, not using it's pattern sequencer)and
DSSI plugins hosted by Qtractor, ALSA MIDI
- via PCI Envy24 MPU an Oberheim Matrix-1000, Yamaha DX7, Yamaha TG33
connected by a MIDI thru chain
I didn't record all instruments at the same time, but one after the other and sync is perfect, no audible jitter.
Unfortunately I couldn't use -Xalsarawmidi for recording MIDI events on MIDI tracks, because there's no bridge.
FWIW, Ardours latency compensation is ok too. Ardour just isn't restoring the SMPTE offset, which isn't a big deal, because I don't use it now and manually setting it does work.
My machine is a
$ hwinfo --cpu
Model: 15.107.2 "AMD Athlon(tm) X2 Dual Core Processor BE-2350"
Clock: 2100 MHz
$ hwinfo --memory
Memory Size: 4 GB
When building the kernel I set
'echo "CONFIG_HIGHMEM4G is not set" >> .config' and
'echo "CONFIG_HIGHMEM64G=y" >> .config' and btw.
'echo "CONFIG_MK8=y" >> .config' too.
The distro is Edubuntu 10.10 Maverick 32-bit + Ubuntu Studio meta packages. Using the FLOSS nv driver for a NVIDIA GeForce 7200 GS on an ASUS M2A-VM HDMI motherboard. The two PCI sound cards are not used as one virtual sound card. Both are active, but I only did use one of the cards. I didn't use any USB device, but e.g. a PS/2 mouse and keyboard. PPPoE and screen saver were enabled, CPU frequency scaling was set to performance.
Still one issue left. Any recommendations for a sound card with good audio qualitiy ;)? I guess I could spend around 700,- EUR and I need minimal 2 or better 4 analog IOs, mic pre amps etc. aren't needed, I'm using a mixing console.
At the moment I 've got two TerraTec EWX 24/96 PCI cards, which cause a muddy bass sound.
Thank you very much for the good work again,
Ralf
Hi Mike,
Forwarding this to the list where users and developers might be able to assist.
Hope this helps!
Best wishes,

Subject: Frequency Space Editors in Linux
Hello Linux Audio,
I just wanted to find out if anyone know of any Linux programs that do sophisticated noise removal from recordings, like the frequency space editing process of Windows programs, Adobe Audition or Cool Edit. I wondered if there is a plugin for Audacity that might do it.
I need to use something other than standard noise sample removal plugins because the crackle is only present when the music is playing, not present during quiet stretches.
Thanks,
Mike
Hello Experts.
Is here library with C #include headers for so what ?
How can i gotta info about Wav, mp3, ogg, m4a, wma [wmv] ... files
SampleRate, Channels, PlayLen( in samples ), bytesPerSample ,
bitrate, VBR ... ,
and after i gotta this info , decode em to RAW stream ?
At least i need everything about Wav, mp3, ogg.
Info about sound file should not be printf()'ed to stdout , but must
be filled in info structure.
Decoder library should have functions - loadFile, Play,
SeekToSample , Stop.
At least possibility - play file from sample or second.part .
Or should be used 2 libs, one for gotta info and one for decoding ?
Any C example and pointer welcomed.
Tnx in advance @ all.
