Hi Experts. Long Long time ago i have burned CDDA with CD-text [with roxio or nero] With cdda2wav -J , i can see my CD-text. Grip read info only from cddb.org, but not from CD-text. With k3b i can elegant grab selected audio tracks, and i gotta file names from CD-Text On target system [Gentoo] is XFCE installed, and here i do not wanna any KDE4/QT progs/libs cdda2wav , cdparanoia i gotta just so what :( audio_01.inf audio_01.wav audio_02.inf audio_02.wav audio_03.inf In inf files is CD-Text info for each track available, but then in must rename each wan manually :( Is anywhere available option/patch/script/gnome-app/whatever... so that i can in cmd line or GTK+ GUI rip wav files with titles ? Tnx in advance Alfs Kurmis cdda2wav -J No target specified, trying to find one... ==== ... ==== CD-Text: detected CD-Extra: not detected Album title: 'Kristine W' [from Lisa St] Track 1: 'Kristine W - Land of the living (Rollo & sister Bliss club mix)' [from 1] Track 2: 'Kylie Minogue - Where is The Feeling(Morales mix)' [from 5] Track 3: 'Kathy Brown _ Give it up (cleptomanics classic)' [from 6] Track 4: 'Crystal Waters - 100 % pure love (PG funked out mix)' [from 9] .... ----

New LV2 host implementation stack

by David Robillard

Hi all, I have released my new stack of libraries for implementing LV2 in hosts: * Serd http://drobilla.net/software/serd A fast, lightweight, dependency-free Turtle syntax library * Sord http://drobilla.net/software/sord An in-memory RDF quad store * Lilv http://drobilla.net/software/lilv An LV2 host library (replaces SLV2) * Suil http://drobilla.net/software/suil An LV2 UI loading/embedding library These libraries collectively replace SLV2, and have no dependencies except amongst themselves, and Glib (by Lilv and Sord, but this dependency will likely be removed in the near future). Serd and Sord replace Redland, making for a much smaller implementation more appropriate for audio software and embedded applications. Overall, Lilv is dramatically faster and leaner than SLV2, enough that the improvement should be quite noticeable from a user point of view (typically in a lag when the host first loads all LV2 data). Anyone using SLV2 is highly encouraged to migrate to Lilv. These libraries are well tested, each (except Suil) with a test suite covering over 90% of the code, which runs without memory errors or leaks. They are new, however, so (as always) there may be problems; feedback (at http://dev.drobilla.net/newticket or personally) is most welcome. More information available at the links mentioned above. For the lazy/eager, all downloads can be found in http://download.drobilla.net Peace, -dr P.S. Packagers, please read the PACKAGING file!

Sound card

by Ralf Mardorf

Thank you all for the help and special thanks to Jörn for mentioning the PCI/ PCIe issue. At last I had to decide to order a 9632 or HDSPe AIO and I'll order the PCIe card tomorrow. I hope the 1 Stereo-IO will be enough for my needs, but I think so, because I can't order more RME gear right now. To loop in 19" FX I only can buy a http://www.behringer.com/EN/Products/ADA8000.aspx, I suspect that I won't like the Behringer's quality for recording instruments, but to loop in 19" reverb for home recoding this should be good enough. Btw. I'll order a KORG NANO for Ardour too. Again, thank you very much to everybody, Ralf

Status of USB M-Audio Fast Track Ultra/Ultra 8R

by Aurélien Leblond

Hi everyone, For those who are interrested in getting the USB M-Audio Fast Track Ultra/Ultra 8R... It works almost out of the box in Ubuntu 11.04 (kernel 2.6.38) but: - Alsa needs to be modified to get the Midi recognized. The fix is already known and I'm very confident it will get to Alsa mainstream soon. - The internal routing of the soundcard is done via software. There is a patch available wit the basic functionality but I haven't tested that yet. Oh and the main developers of this functionality has been posting stuff today on the Alsa-Devel mailing list, so he's working on it. - There is a small bug where the sounds cards is dropping samples. Daniel Mack from the Alsa-Devel is working on it. The most complete thread on the subject is here: http://forums.m-audio.com/showthread.php?714-Not-a-problem.-FastTrack-on-li… Overall, it's not as well supported as the Edirol UA-25Ex for example (the USB one I used to have), but I'm very confident it's only a questions of months. And the more people get it, the more information we can compile, the fastest the issue is going to be fixed I suppose.

What sound cards are recommender by developers? I'll order next week!!!

by Ralf

Pardon that I ask this on the developers list, but it seems to be the best place regarding to the information about hardware, that is or isn't well supported for or by Linux. I'm flirting with the idea of buying a RME PCI card or firewire device or if recommended a card from another vendor. The device should have around 4 analog IOs, for MIDI I could keep one of my Envy24 cards, as long as a new device only needs one PCI slot. I guess PCI is less problematic than firewire? I'll order next week. It's important that the analog IOs and converters etc. keep the sound without audible loss, similar to consumer equipment, that is not the most worse. Professional sound quality isn't needed, but my TerraTec EWX 24/96 or similar Envy24 cards and all those onboard devices I ever heard, don't reach good consumer quality, they produce marked loss for the sound quality. I could spend 800,- EUR or less ;). Any recommendations for sound cards? I already got some recommendations and until now this one seems to be the most confidence inspiring device ... just a feeling ;): http://www.thomann.de/gb/rme_digi_9632_hdsp_pcikarte.htm OTOH, I'm doubtful, regarding to the costs. I thought that new devices are more expensive. Somebody else recommended this one: http://www.thomann.de/gb/focusrite_saffire_pro_40.htm I can't ask friend, because they won't care about compatibility to Linux :(, I guess that e.g. Motu isn't (well) supported. Before I order a sound device, I'll ask if I could test it, when ordering at Thomann or a similar dealer. The problem is that I have to order, because AFAIK there are no good music stores near to my hometown Oberhausen/Rheinland, that are easily reachable by public transit, dunno, perhaps Kurt Spiecker + Dirk Pulch are still ok. Best, Ralf

Cracking sound via USB (ALSA urb.c:480: frame 5 active: -18)

by Aurélien Leblond

Hi, I seem to have an issue with USB soundcards on my laptop. I have tried two of them, but I keep getting crackling sounds while playing with Ardour or Hydrogen. Everytime this crackling sounds occur, I get the following in dmesg: ALSA urb.c:480: frame 5 active: -18 The Kernel is 2.6.39 with Irqthreads, Alsa is the git version (1.0.24). I have tried a lot of things already, but I'm really ready to restart the investigation from scratch and to provide any information!

If I should need more channels I'll order a cheap ADAT device at another time. More channels might be needed to do rehearsal room recordings, with cheap microphones, hence the sound quality is less important, "live" music has an advantage regarding to the feeling compared with home recording, just for home recording I wish to get the most near professional sound that is possible by my equipment, but at home I don't need much channels. 2 for the stereo sum and some to loop in a 19" reverb or to record drum sounds from a drum module by separated channels at the same time. > > > As long as I'm using a mobo with PCI slots I can use AI4S-192 AIO and > > AO4S-192 AIO with a DSP 9632 and when I switch to a mobo with PCIe only > > I can switch from DSP 9632 to HDSPe AIO and keep AI4S-192 AIO and > > AO4S-192 AIO (and e.g. a BEHRINGER ADA8000 ULTRAGAIN PRO8 DIGITAL ;)? > > This sounds right.

I tries to switch from LAD to LAU, regarding to current user queries, but it failed. Hi Admin [1] ;). Hi Gustin :), hi Ubuntu Studio users list :), pardon LAD ;) IIUC a HDSPe AIO or DSP 9632 is all I need, if I just need a stereo IO? I only need to buy a BF-BOXLRMKH or BF-BOCMKH breakout cable? If I need additional IOs and wish to avoid Multiface firmware issues, I can add AI4S-192 AIO and AO4S-192 AIO. If I need much more IOs and don't have enough money for RME IOs, I can e.g. use a BEHRINGER ADA8000 ULTRAGAIN PRO8 DIGITAL by ADAT connection. The sound quality might be less good and I guess this will add extra latency and Ardour won't auto-compensate this extra latency automatically? As long as I'm using a mobo with PCI slots I can use AI4S-192 AIO and AO4S-192 AIO with a DSP 9632 and when I switch to a mobo with PCIe only I can switch from DSP 9632 to HDSPe AIO and keep AI4S-192 AIO and AO4S-192 AIO (and e.g. a BEHRINGER ADA8000 ULTRAGAIN PRO8 DIGITAL ;)? Using a DSP 9632 with a PCIe to PCI bridge doesn't work or at least could cause issues?
