Hi, Once I had jack-rack racks with names like 'Lennon' and 'tube amp' in it, but can't find them online. Where those patches coming from you Noack? Can't remember it... Regards. \r

RME HDSPe AIO is completely supported - was: [Alsa-user] Which pci-e card?

Hm? I don't know what was bad, that it didn't work before. Tired, making a typo? Choosing a bad combination of values? I've got it ... -p520 oops. Thank you very much. Btw. I'll use ADAT too, regarding to severe weather I didn't get around to test/use the card + ADAT. I just listened by the cards outputs to a youtube video. I guess this night I'll have fun with the card :). Regards, Ralf

Re: [LAU] OT - syncing partially out of sync video and audio in existing files

by Jeff Sandys

Hi, ... I'd like to fix some videos that have partially out of sync video and audio, meaning that beginning at a certain point in the video the audio is suddenly out of sync by a couple of seconds. There's no constant change, the delay seems fixed once it's there. I wonder how to fix such a thing. The files are xvid encoded videos and vbr mp3 audio inside avi containers. I thought it should be reasonably easy to cut and move the audio (re-encode if unavoidable, but I know it's in principle possible without) and put it back in a container, but I didn't manage. Can someone recommend a program/workflow that would allow this? I tried: - Avidemux: ... - openshot: ... - kino: ... - openmovieeditor: ... - cinelerra-cv: ... - pitivi: ... - kdenlive: ... I thought it would be a simple task, really nothing fancy. Seems like I was wrong. Regards, Philipp Phillipp, I had a problem with out of sync audio using a camera that recorded using VBR. Avidemux was able to fix this with Audio/Build VBR Time Map http://www.avidemux.org/admWiki/doku.php?id=using:vbr_mp3 I can't move or stretch audio in Avidemux, but this time map function fixed my out of sync problems. -- Jeff

acid techno test version 2

by James Morris

probably not acid, probably not techno, but i don't really care! probably a little on the unfinished side, but i've swivelled back to programming again, so unless i release it now it's never likely to see the light of day. http://jwm-art.net/audio/acid_techno_test_version2.mp3 you'll notice a few tips taken from criticism of the previous version, namely, it's faster. james.

OT: Overvoltage protection aginst lightning for audio studios

by Ralf Mardorf

Sorry, this is OT regarding to Linux, but not for audio in general and perhaps it could protect some people from the list against a popular misconception about lightning protection. Does somebody know how (in)effectively overvoltage protections for wall sockets in pre-WWII residential buildings are? I suspect that were I live, will be no pre-protections. It seems to be that a concrete-footing ground electrode and ground fault interrupter were the only things that were retrofitted and btw. I'm even not sure if the concrete-footing ground electrode isn't just a fake. AFAIK know consumer wall socket overvoltage protections are completely useless, when living in a pre-WWII residential building. Does anybody know if there's a way to protect equipment against damages by lightning when there are no pre-protections? Regards, Ralf

Lambda USB Interface

by David Baron

The Lambda Studio looks like a decent interface, USB powerd, five input, 2 track simultaneous recording, MIDI, Mike preamps, etc. Has anyone successfully used these in Linux, Alsa, Jack? (Since my rusty-trusty Dman2044 with its nice chunky breakout box has not had drivers since Win98, I DO need an alterative with proper connections!)

Linux Audio Diagnostics Tool

by allcoms

Hi Linux Audio Land! I've been thinking recently just how useful it would be- certainly to Linux audio distros and (Linux (audio)) newbs, if we had an app that could tell you what sound systems are currently active and let you test them- both audio in and output for ALSA, JACK and Pulse at the very least but FFADO, esound, phonon and whatever else would be great to see included too. Even for a Linux old-timer like me its tough remembering all the different mixers, daemons and diagnostic utils and commands to work out where you are when you have sound trouble. If it can't fix your problems automagically then it would be good if it could advise the user on how to get their desired sound system functional, if not optimised as in the case of JACK as I think that could end up being its own app or should be integrated into qjackctl. JACK gives more useful error messages now which should help in putting something like this together but AFAIK there's nothing out there like this atm. Anyone know of an existing app like this or if work has already begun on such a tool?

[ANN] Virtual MIDI Piano Keyboard 0.4.0 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 * Touch screen support (multi-touch) if it is supported by the OS and hardware. * RtMIDI-1.0.14 with Jack MIDI support. * New network MIDI driver (UDP multicast) compatible with IpMIDI and QmidiNet. * New platform: Symbian^3 port. * New translations: Dutch by Wouter Reckman, and Swedish by Magnus Johansson. * Fixed a crash when changing the octave base while channel is 10. Thanks to Mike Cookson for the report. * New build options: * RTMIDI_DRIVER: selects the RtMIDI backend. Default depends on the OS. Allowed values: ALSA, JACK, COREMIDI, IRIX, WINMM, NET. * PROGRAM_NAME: selects the executable name. Minimum requirements for all platforms: CMake 2.8 and Qt 4.6 Please use the mailing list <vmpk-devel(a)lists.sourceforge.net> for questions and comments. Thanks.

Hydrogen and Hi-hats

by S. Massy

Hello, all, Hydrogen has some very nice sounding sets, but in each and every one of them, the open hi-hat is not muted by the pedal. I was wondering whether that was somehow configurable or whether it was just idiosyncratic to hydrogen. I'm not using the GUI, of course, just driving the engine through midi, so perhaps that is the reason for this behaviour? Cheers, S.M. --
