Hello, It's a bit of a long shot, but I was wondering whether any one had ever written a simple programme/script to manipulate zyzaddsubfx/yoshimi patches, given that they are simply compressed xml. Cheers, S.M. --

Bluetooth A2DP pitch shifting

by Ken Restivo

I have been lately using a Bluetooth A2DP headset to listen to music. Every now and then, it drops pitch! It slows the music down, by as much as a semitone, for several seconds, then comes back slowly. I rather like the effect; it's like an old cheap analog vynil turntable with a bad motor or worn belt. What could be causing this? The signal path is Ogg Vorbis files to Android phone (obligatory Linux content!) to A2DP stereo headset. Also, I'm very much enjoing the best of 2010 mix! The quality of the music is excellent. I have it on shuffle along with the latest Radiohead record, and I cannot tell which is the multi-mega-superstar-major-label-millionaire-rock-band release, and which is a guy in his bedroom knocking stuff out on his laptop for fun in spare hours after work. Linux audio is definitely as ready for prime-time as the prime-time is. I digress, but nonetheless, I will BOX THE EARS of anyone who diverts my precious thread into discussions of apocalypse, conspiracies, or revolution. You have been warned :-) -ken

FW: Frequency Space Editors in Linux

by Ivica Ico Bukvic

Hi Mike, Forwarding this to the list where users and developers might be able to assist. Hope this helps! Best wishes, Ico -----Original Message----- From: Michael Van [mailto:m_vanwagner@yahoo.com] Sent: Saturday, April 09, 2011 12:44 PM To: ico(a)linuxaudio.org 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

LinuxSampler and SFZ

by S. Massy

Hello, Today, I built linuxsampler from CVS in order to be able to use the SFZ engine; however, when I do: LOAD ENGINE SFZ 0 SET CHANNEL AUDIO_OUTPUT_DEVICE 0 0 LinuxSampler segfaults. Has any one had any success using linuxsampler together with SFZ, ir is it still very much under development at this point? Cheers, S.M. --

Playing a concept album...

by lanas

Hello everyone, This is not about the creative side of music but rather about how to play some 'canned' (!) music. A concept album. A concept album is distinct from other albums as the pieces flows into one another. Such an album, when played on a traditional CD player, effectively gives the impression of a 'flow motion' (no pun here on a famous CAN album !). But, once ripped to ogg files and played from a m3u source (eg. sequentially) there are - no surprise - small blank cuts between each piece, which can be disturbing in such a context. The context here being Peter Hammill's 'Incoherence' concept album. Does anyone have a recipe modification of those files (or ogg player options - I now use either ogg123, mplayer or xine) or whatever other way that would restitute the original flow feeling ? Do you know what I mean ? Cheers.

jack clipping level in dB

by andy baxter

Hi, I have a signal from a Supercollider program which goes into jack. I want to adjust the signal level so it's as loud as possible without clipping. Could someone tell me what is the loudest sound that doesn't get clipped in dB, as measured by ardour or meterbridge for example? Thanks, andy

QasMixer: really nice ALSA Mixer app

by Gabriel M. Beddingfield

I was looking for some good code to steal, and I ran across QasMixer (http://xwmw.org/qasmixer/). It is an ALSA mixer application very much like the CLI `alsamixer`. My favorite feature is that it allows you to browse and manipulate /all/ of the cards on your machine at the same time. (In contrast, with alsamixer you have to start another process with something like `-c 1` for your other sound cards.) QasMixer used to be called Alsamixer-Qt4. I have absolutely no affiliation with QasMixer, I just think it's a very useful and well-done application. -gabriel
