OT: So what do you think sucks about Linux audio ?

Linux audio is about freedom and a harmless default wallpaper about something from a creative commons music community inflame passions of some Linux users. Why? It's free from porn, showing a virtual "school girl" singer. And other wallpapers are more professional, just because this default wallpaper does show a "school girl"? Why should there be copy right issues? The idea of creative commons is to avoid copyright issues. http://creativecommons.org/weblog/entry/35879 For me it's very strange that it's classified as porn. It doesn't fit to my taste, there is some commercial background, but it's about creative commons music and free from porn. Even the minimal erotic is that harmless, that in Germany you're allowed to show this picture in a kindergarten or elementary school. Most default wallpapers I've seen are much more worse, completely without erotic, but instead of that unskilled art, that I would protect children against those unaesthetic wallpapers. Regards, Ralf

Re: [LAU] So what do you think sucks about Linux audio ?

> So what do you think sucks about Linux audio ? well, at last i know. that's the overall approach to grow the community by any means. which is about quantity, but not quality. so, there's too much attraction for people that want to be unlike the others, but can't motivate their choise in any other way. needless to say that they are doomed to be forever unhappy with their choise, since what they really want is another clone of win and/or mac way. and why do we need growing the community by any means? that's the most obvious way to show to the others that we're respectable too. but that's the dead end. and that's all. the next message will be what i like about linux audio as THE DIFFERENT approach (as i promised :))

[ANN] Virtual MIDI Piano Keyboard (VMPK) 0.5.1 has been released

by Pedro Lopez-Cabanillas

Virtual MIDI Piano Keyboard is a MIDI events generator and receiver. It doesn't produce any sound by itself, but can be used to drive a MIDI synthesizer (either hardware or software, internal or external). You can use the computer's keyboard to play MIDI notes, and also the mouse. You can use the Virtual MIDI Piano Keyboard to display the played MIDI notes from another instrument or MIDI file player. Changes for v0.5.1: * Fixed bug #3599827. No default keyboard shortcuts available in 0.5.0 on fresh installations * Qt5 build compatibility (but not fully functional) Requirements for all platforms: CMake-2.8 and Qt-4.8 or later. Please use the mailing list <vmpk-devel(a)lists.sourceforge.net> for questions and comments. Thanks.

jackdbus eating 100% cpu after a while

by Florian Paul Schmidt

Hi, I was a long term jackd1 user and my first action on a new linux installation (mostly using Ubuntu) was normally to remove pulseaudio as it was badly configured and/or buggy. Things have changed and I really started to like PA for everyday stuff. And then jackdbus came along which together with the device reservation API and the jackd sinks promised to make using these two things together more easy. This mostly works fine, except for the device reservation bug in PA which is easy to work around though: - Make sure no audio process is actively using the soundcard you want jackd to use - Run pulseaudio -k - Run jack_control start I have noticed some issues with jackdbus though: a] jack_control start sometimes doesn't work at all after the first time it failed to aquire the device. A killall -9 jackdbus is in order to restore it b] after some hours of operation jackdbus starts to eat 100% cpu on two of my four cores. Are these known issues? I use Ubuntu 12.10 and jackd: fps@mango 12:08:21 .../Games/Xonotic/ $ jackd -v jackdmp 1.9.9 [...] How to diagnose the 100% cpu thing more closely? The ~.log/jack/jackdbus.log shows nothing suspicious. Thanks and regards, Flo -- Florian Paul Schmidt http://fps.io

I find: pasuspender --sleep 5 & ; jack_control start Will allow me to start jackdbus even while pulse is streaming. Actually I use pasuspender from qjackctl to do the same thing. > I have noticed some issues with jackdbus though: > > a] jack_control start sometimes doesn't work at all after the first time > it failed to aquire the device. A killall -9 jackdbus is in order to > restore it jack_control exit works for me. This is part of the bug above, when jackdbus fails to get the device, the jackd part dies but the dbus part doesn't (it seems, I don't know the code well enough) It would be interesting to compare this behaviour with jackd2. > b] after some hours of operation jackdbus starts to eat 100% cpu on two > of my four cores. I have left jackdbus running for at least 5 days and have not seen this show up. PA has been used during that time (audacious and fire fox) as well as other jack clients. I would be interested to know if running jackd instead of jackdbus is the same or different. There are some patches on the way for jack2 in ubuntu as well. (in testing) > > Are these known issues?

USB-MIDI

by Folderol

Does anyone have any experience of using a MIDI-over-USB dumb keyboard? Does it need special drivers or can I just plug it in and have it automatically found by my machine? I'm hoping to be able to use Yoshimi on my netbook at an impromptu gig. I'm running a cut-down debian, but will get qjackctl from the repository (which usually fetches and configures everything else I need. -- Will J Godfrey http://www.musically.me.uk Say you have a poem and I have a tune.

Tracking at 44.1 vs. 48k vs 96k?

by James Stone

Are there any advantages to using 96k (or 48k?) if the final target is 44.1k/16bit? I am thinking that tracking at 44.1k / 24 bit should be more than sufficient for most (non-pro) purposes? I read somewhere about higher bitrate being important for headroom for audio processing plugins, but does samplerate also have an effect on this? James
