Re: [linux-audio-user] Extracting SysEx from Mid

A very similar tool: MIDICSV: MIDI files to CSV (Comma-Separated Value) format, by John Walker. http://www.fourmilab.com/webtools/midicsv/ You can use one that programs to generate a text file containig the events, and then use a text editor or script to select the interesting ones. Another option is to use a MIDI monitor program, and feed it with a MIDI player. For instance: $ kmidimon & $ aplaymidi -p KMidimon:0 anysong.mid Then, use file->save to store the received events into a text file. Remember that KMidimon can filter out all event types except sysex. Regards, Pedro

[linux-audio-user] edit mp3 files?

by Florin Andrei

I have several MP3 files that I have to edit - there's a 1 or 2 minutes intro on each file that needs to be removed. I want to do this in a way that does not require re-encoding the file. Essentially, I just want to remove a portion at the beginning of each file and keep the rest untouched. I tried Audacity first, but it seems like it's importing the file in some internal format. If I chop off the head of the file, then I have to export (re-encode) the rest, right? Any other idea? -- Florin Andrei http://florin.myip.org/

Re: [linux-audio-user] CCRMA and yum

by thewade

Hi Fernando, So that GPG key works. I just included the URL to the file on the net insteadd of downloading the file. This is probably defeating the purpose of the GPG because people could theoreticaly modify a rpm and change the key on your site at the same time, but that seems unlikely. I am encountering some problems though. Probably descrepancies between the livna repository and the ccrma repository. Can you tell me if I am correct? yum -y update [lots of messages here...] Error: Missing Dependency: libavcodec.so.51 is needed by package xine-lib Error: Missing Dependency: faad2 = 0:2.0-0.lvn.5.4 is needed by package xmms-faad2 And it ends there. Just to see if it was missing some file I built from source I ran: rpm -qa | grep faad xmms-faad2-2.0-0.lvn.5.4 faad2-2.0-0.lvn.5.4 rpm -qla | grep libavcodec /usr/lib/libavcodec-CVS.so /usr/lib/libavcodec.so /usr/lib/libavcodec.so.51 So the files are there (and are from RPM's in the livna repository) so I guess the problem is that CCRMA is trying to overwrite these files: am I right? Is there a way to get the CCRMA files to use the livna files? How can I tell if the versions are compatable? Thanks again for all the work you put into CCRMA, and into helping meatheads like myself! -thewade

I would be delighted to do this. Perhaps once I have the score for "Arabesque" & have practiced it, I can record it along with the scores for two other pieces of yours. Best wishes, Gavin.

I generally don't listen to much other than metal and industrial, but this song is very nice. There's something I can't describe about it... Anyhow, that Zoom you are using sounds nice. I'm actually surprised, because a couple other Zoom things I've tried really sucked. Especially the 505II, that thing is noisier than an interstate. So the Zoom you have, it works as a usb-audio device in Linux? What else did you use to record that track, as far as the software and other instruments are concerned?? Dana

Re: [linux-audio-user] [OT] Guitar amp

by Sean Edwards

Fender has their Pre CBS and Post CBS era's, Peavey has the rumor of making proprietary components that can not be replaced outside of their factories, and Behringer is taking flack for making good prducts at affordable prices. The best thing you can do is go find for yourself what you like. --- Lee Revell <rlrevell(a)joe-job.com> wrote: > On Sat, 2006-02-18 at 10:02 -0800, Sean Edwards > wrote: > > I don't think their amps are copies of anything. > Some > > of their foot pedal products were restricted from > sale > > in the U.S.A. over some patent disputes, but I > have > > not heard of anything similar with their amps. > > This was the case that got a lot of publicity: > > http://homerecording.com/bbs/archive/index.php/t-74439.html > > But whatever, I don't think there's a vendor in > existence that NEVER did > anything shady... > > Lee > > __________________________________________________ Do You Yahoo!?
