I have a long .wav file which I want to burn on CD. I want to set some marks so that one can jump to certain points in the file during playback. Something like a live recording with different pieces of music. I do not want these 'track marks' to be audible (no pause between the numbers). How do I do this? Robert Epprecht

Re: [linux-audio-user] Make Stereo WAV out of Two Separate Files and Other Weird Activities

by Martin McCormick

Them writes: >Audacity can do this kind of thing: Thank you. Will it run in command line mode without the GUI? I forgot to mention that X isn't an option. It is okay if it needs GTK libraries or something like that, but if it only runs under a GUI, it won't work here. Sorry about not being more specific. Martin McCormick

[linux-audio-user] Make Stereo WAV out of Two Separate Files and Other Weird Activities

by Martin McCormick

Is there a way to take two mono .wav files and combine them in to a stereo .wav file? The way I imagine something like this is that the utility combining the two .wavs would have to pad the shorter of the two files out with silence. This gives you two independent streams of audio to play with. Along the same type of thinking, is there a utility that splits a stereo .wav file in to two mono .wavs? Trust me. There are a number of uses for bending the technology in this way. Martin McCormick WB5AGZ Stillwater, OK OSU Information Technology Division Network Operations Group

Last thing to try is to start the vstserver with the --nonrealtime option to see if it can be the watchdog that is screwing things up.

[linux-audio-user] ICE1712 and Envy24: multiple soundcard sync

by Michele Spinolo

Hi guys. I installed Suse9.1 with ALSA and 3 Terratec EWS88D connected with the internal clock sync cable: the system seems to be properly configured and 3 ICE1712 drivers are loaded and all three cards work properly. Now I would like to set one of them as "Master" and the others as "Slave", but I can't find this option under Alsa Mixer, Envy24 Control or others tool. Does anyone have an idea how to do this? Thanks! Michele

[linux-audio-user] jack_fst build question

by Mark Knecht

Hi, I got past my Wine problems today, finally got libfst built successfully and was next trying to build jack_fst. (I hope this is worth the effort...) ;-) However, it's not happy with libfst: mark@flash jack_fst-1.2 $ ./configure checking for a BSD-compatible install... /bin/install -c checking whether build environment is sane... yes <SNIP> checking for libfst >= 1.3... Package libfst was not found in the pkg-config search path. Perhaps you should add the directory containing `libfst.pc' to the PKG_CONFIG_PATH environment variable No package 'libfst' found configure: error: Library requirements (libfst >= 1.3) not met; consider adjusting the PKG_CONFIG_PATH environment variable if your libraries are in a nonstandard prefix so pkg-config can find them. mark@flash jack_fst-1.2 $ What is the pkg-config search path? How's a user like me supposed to adjust this? I've not seen this problem for a long, long time and I've never seen it on a Gentoo box. libfst is installed: mark@flash jack_fst-1.2 $ slocate libfst /usr/local/lib/pkgconfig/libfst.pc /usr/local/lib/libfst.so /home/mark/data/fst-1.5/libfst.pc.in /home/mark/data/fst-1.5/fst/libfst.spec.c /home/mark/data/fst-1.5/fst/libfst.spec.o /home/mark/data/fst-1.5/fst/libfst.so /home/mark/data/fst-1.5/libfst.pc mark@flash jack_fst-1.2 $ and I've run ldconfig just for completeness but it still doesn't allow this to build. Thanks, Mark

[linux-audio-user] OpenJay Development Krew [OJDK]

by J_Zar

Finally, I would like to introduce the OpenJay Development Krew [OJDK], which actually is only a mailing list with little mail-traffic. The OJDK is the right place for OSS Dj oriented software developers: here you should find the right audience for discussing, sharing and improving code, take / give suggestions and similar. The OSS software is actually a powerful alternative (and with always greater occurrence a refferral point) in many fields. Although it is not the djing OSS case. There are many reasons for that: little OSS compatible hardware, few and small projects... few users... The closed ring of open dj software is based upon few users and few developers. Crashing it is my intention. To do that my efforts are enclosed in three projects (enough to cover the whole issue) : - OpenJay.org : the user side of the opensource dj world ; - OpenJay Development Krew [OJDK] : the developer side of the opensource dj world ; - Jay'O'Rama : my personal software solution which I'm developing since 1 year and that will be only an alternative ; You should think to OJDK not as a project factory, but mainly as an improving factor for code and a discussing place. Projects will come if needed and desired. Please...if you are an interested developer, CATCH THE OPPORTUNITY, join the OJDK list and mail it! More than money or hardware, I need more than ever some community help in these directions... There are already some project developers joined our little community. See the homepage for more info: http://www.openjay.org/ojdk http://www.ojdk.tk -- J_Zar Gianluca Romanin ---------------- see you at OpenJay.Org
