[linux-audio-user] Libsamplerate support for ecasound

by ed orphan

How do you get Libsamplerate support for ecasound? Is there some program that has to be installed or is this a configuration issue? I notice that when I do ./configure while installing ecasound it ends with a list and this list says that there is no Libsamplerate support. I have no idea what it means, but it must be important or it wouldn't be on the list, right? Anyone know how I get Libsamplerate support active?

[linux-audio-user] Re: Rosgarden, jack_fst and B4

by Timo Sivula

I installed all KDE development packages from the FC1 install CD and now I finally got rosegarden to compile from sources. I applied the patch and compiled. Unfortunately B4 still goes quiet after the first playback. How do I ensure I did the patching right? I cd:ed to the sound directory under rosegarden and applied the patch command there. What would the right syntax be? Why doesnt the CVS version compile while the 0.9.9 version does? Are there some new dependencies I should fulfill compared to 0.9.9. br, Timo ..............................................................

[linux-audio-user] audio spectrometer

by Andrew Gaydenko

Hi! The aim is to make measurement laboratory, in particular, to measure distortions of audio amplifier. Using JACK, I can route line ins/outs, find clean sine signal and get amplified one, and then route last to... Well, the questions are: - are there some graphical FFT frontend to see signal harmonics? - has anybody success experience here? - are there some caveats and traps in such measurement? I have 24/96 card (Terrateck Aureon 7.1) with (as I think :-) good DAC/ADC. So, measurements accuracy may be rather high. Is it so? Thanks! Andrew

[linux-audio-user] [ANN] dssi-vst 0.3

by Chris Cannam

dssi-vst 0.3 released! ====================== The 0.3 release of dssi-vst is now available. dssi-vst is a DSSI plugin wrapper for VST effects and instruments with GUI support, allowing them to be loaded into any DSSI host. It requires a fairly recent version of Wine (this calendar year at least). dssi-vst is available from the download page at http://dssi.sourceforge.net/ The main improvement since the initial 0.1 release is that dssi-vst now works correctly with plugins with complex GUIs that use back-channel information to communicate things like patch data to the audio plugin. In practical terms, this means that VSTs with test keyboard widgets, patch load and save, and other natty features in their GUIs should work properly as DSSI plugins without losing automatability for the true automatable parameters.

[linux-audio-user] Rosgarden, jack_fst and Native Instruments B4

by Timo Sivula

After a considerable amount of work I now can use the B4 vst instrument under Linux. The setup is as follows: Fedora Core 1 + Planet CCRMA Wine-20041019 jack_fst-1.2 with Mark Knecht's hack for Wine-20041019 Native Instruments B4 However, when using B4 as a soft synth under Rosegarden it plays perfectly for the first playback. When I stop the sequencer and "rewind" to the beginning of the track and start playback again, B4 goes quiet. The B4 UI still works, I can see the B4 UI keyboard moving in sync with my midi keyboard, all controls work, I can see the B4 midi and audio connections in qjcaktctl, and Rosegarden shows midi traffic on the channel assigned for B4, but there is just no sound. If I kill the B4 window and restart and reconnect it, it works again, for one playback. I have tried reconnecting the midi and audio connections and I have set and unset the mute and bypass buttons in the VST window to no avail. B4 stays quiet until I restart it. I have tried this also without Mark Kencht's hack of jack_fst-1.2 in wine-20040505 but the behavior is the same in both cases. Any ideas what could be wrong? B4 works perfectly for hours when using it outside the sequencer environment, but I would also like to use it in Roseqarden. br, Timo ..............................................................

You are not far from the truth there ;-) I googled for the file make was complaining about and the only refrence I found was to the Rosegarden4-debuginfo packages. Installing them did not help either. Any alternative solutions? Timo

[linux-audio-user] Voip with snd_intel8x0 module

by Rick B

Hi all, I'm trying to get voip in a video game (ut2004) working on my Nforce2 chipset with Alsa. This is with the 2.6.8.R9 kernel from Planetedge. There appears to be some software mixing support available now with the Alsa snd_intel8x0 module as when I play the game I can hear the games audio and my mic at the same time. Am I wrong about this? Is there some other means by which I can hear both audio sources at the same time? The reason I ask is because I still cannot get voip to work even though I can hear my mic over my pc speakers. I am wondering if I still need to use the dmix plugin in my .asoundrc file to get voip to work as some older(?) documentation says. Can someone point me in the right direction please. Rick B

[linux-audio-user] List Digest Format

by Spencer Russell

Hullo, I'm wondering if there's a way to have the digest sent with the included messages as attachments, instead of just one big message. Another list I'm on does that, and it's really convienent to just hit "v" (in mutt) and see a list of included messages to browse through. Also, then messages already have the correct subject line when you reply to them. I tried searching the archives, but of course, searching for "digest" brings up a whole host of unwanted results. Thanks, Spencer
