[linux-audio-user] Connecting alsaplayer to jack

by David L. Craig

I've gotten jack to run via sudo on my Gentoo system but when I attempt sudo alsaplayer -r -o jack I get: Failed to load output plugin "jack". Trying defaults. I'm guessing I'm missing an ebuild, but I think I have all the right ones with "jack in the name, as emerge --search jack yields: [ Results for search key : jack ] [ Applications found : 12 ] * app-crypt/jacksum Latest version available: 1.6.0 Latest version installed: [ Not Installed ] Size of downloaded files: 401 kB Homepage: http://www.jonelo.de/java/jacksum/ Description: Java utility for computing and verifying checksums: CRC*, MD*, RIPEMD*, SHA*, TIGER*, WHIRLPOOL License: GPL-2 * media-libs/bio2jack Latest version available: 0.4 Latest version installed: 0.4 Size of downloaded files: 466 kB Homepage: http://bio2jack.sourceforge.net/ Description: A library for porting blocked I/O OSS/ALSA audio applications to JACK License: GPL-2 * media-libs/libjackasyn Latest version available: 0.10 Latest version installed: [ Not Installed ] Size of downloaded files: 69 kB Homepage: http://gige.xdv.org/soft/libjackasyn Description: An application/library for connecting OSS apps to Jackit.

[linux-audio-user] Music CD Data Base

by Martin McCormick

How does one read the MCM number and any other non-audio data from a music CD? I want to build a MP3 server for our house and definitely do not want to manually enter data from the art work in the CD box. It is my understanding that one can retrieve the MCM catalog number and match it against a data base to turn that in to an album name and song titles. Is this correct? I also want to do this without any X applications. The computer is good enough for command-line shells, etc, but is only a 400-meg Pentium with 65 megs of RAM. I am home-brewing this server which will probably end up being a collection of shell scripts and C applications written by me but I realized that I wasn't sure how to let the CD's own data speak for themselves. While ripping tracks using cdparanoia, I frequently see a short track numbered 0 which is not a song but appears to have some sort of binary data. CD's I burn or some commercial CD's do not have this special track. What is it? Thanks for any answers or suggestions. This is one of those times when Google searches turn up a boatload of all the wrong information, probably because I didn't use the right search terms, but nonetheless, I haven't found what I was looking for yet.

[linux-audio-user] transposing frequency

by Atte André Jensen

Hi Suppose I have an A with a frequency of 440 hz. Which formula should I use for transposing x semitones up/down? So which frequency would the Bb a half step higher for instance have? What about cents (1/100's of half steps)? -- peace, love & harmony Atte http://www.atte.dk

[linux-audio-user] Re: How to get good vocal sound

by Juhana Sadeharju

I have recently asked this question too. I would like to write an effect specially tuned to create a good vocal sound. Clear but spacious effect. Dattorro's plate reverb is of Lexicon plate type. I would use that for vocals. Is Tim Goetze's Versatile Plate Reverb an implementation of Dattorro's? I have implemented it too if anyone would like to have the code.

[linux-audio-user] how to synthesize this sound

by Atte André Jensen

Hi I can't figure out how to do this classic sound that's heard on this file http://www.atte.dk/download/sound.ogg. The one I'm talking about is the rising sound in the background. I guess it's modulated with a square lfo, but I can't figure out what's filter and what's pitch. If someone did this sound a zillion times an could explain the idea, I'd really appreciate it.

The exact formula is that, to go up a semitone, you multiply the frequency by the 12th root of 2, that is 2 to the power of 1/12. I'm not sure how it works with cents, but I'm guessing that the ratio is 2 to the power of 1/1200. Peter Clarke

[linux-audio-user] Automating qjackctl & xmms start-up

by Michael T D Nelson

Hi all, I have a quick question... I'd like to automate the start-up of all the programs which are needed to play my collection of music. The aim is to make it easier for other users of my machine (who aren't so familiar with Linux). At the moment, I've written a simple bash script which starts qjackctl, xmms and konqueror pointing at the folder with my music in. This works fine, but the user still has to click 'Start' on qjackctl. Can I automate this somehow? I know that I can start jack straight from the script, but sometimes I like having the GUI. Thanks Michael

[linux-audio-user] new songs on-line

by Dave Phillips

Greetings: I've put two new recordings on-line: http://linux-sound.org/itsover.ogg http://linux-sound.org/tomorrownight.ogg Both pieces recorded in Ardour and mastered with JAMin. I've also revised and updated this page: http://linux-sound.org/ardour-music.html I've removed two pieces from that page and added the new songs. I've also updated the other Ogg files on the site, they've been remixed in Ardour and mastered with JAMin. Blessings upon the heads of all Linux audio software developers ! :) I hope you enjoy the new material. It's Over is an original (and has been linked on the LAM site), Tomorrow Night is my rendition of a ballad by Lonnie Johnson. Comments and constructive criticisms are always welcome. Best, dp

[linux-audio-user] Re: Linux Sampler

by Juhana Sadeharju

Hello. Could anyone extract the last pure GPL version of Linuxsampler out of CVS? Perhaps one of the LS developers could do that (as they know the versions)? Do the same with libgig etc. if they have experienced similar change. One should also collect the bug reports of LS and the mailing list archives after the license change. I have blamed LS developers for not making the development documentation available via their public webpage. Now it hits hard as the developers of alternative version need to reverse engineer Gigasampler all over again for the missing parts. If LS developers could make all dev documents up to today available for the alternative developers, would that be nice. The dev docs would help them to catch up the LS as soon as possible. Do you see any problem in this kind of arrangement? I don't. (But if LS eventually becomes pure-GPL, all this trouble is not necessary.)

[linux-audio-user] Re: [linux-audio-announce] GStreamer 0.10 is here!!
