Hi Q! Ecasound can do the trick, but in two steps, I'm afraid to say: for F in *.wav; do ecanormalize $F ecasound -i $F -o normalised$F -eadb:-0.3; done You need ecasound and ecatools for that. I think though, that -0.3DB seems rather hefty. Well there is a difference between db and dbfs, have to look it up on Wikipedia. Ecasound's version must be 2.7.0 I believe. Otherwise you can use a different amplifier, which works in percentage of maximum volume: ecasound -i input.wav -o output.wav -ea:97 That is lower volume to 97% of the current volume. Hope you can work with that. If not, well there's always csound and its relatives, but that might really go a little overboard. :-) Pianoly yours Julien -------- Music was my first love and it will be my last (John Miles) ======== FIND MY WEB-PROJECT AT: ======== http://ltsb.sourceforge.net the Linux TextBased Studio guide ======= AND MY PERSONAL PAGES AT: ======= http://www.juliencoder.de

DIY messurement-mic

by Fabio

I have a Panasonic W61 capsul here, famous for having flat frquency response. used for example in the Behringer C8000 (don't remember the correct model number) in fact it came in a cheap mic I bought only to have the capsul: http://www.leson.com.br/v1/produtos/microfones/index.php?pro_id=133&cat_id=… problem is its an unbalanced circuit using a 1,5V baterie. I want to make it work balanced and with phantom power there is a famous project of a pre-amp circuit called P93: http://s1.postimage.org/5m4edvc6m/p93_f6.gif but since I have a preamp I'm asking myself if it wouldn't be sufficiant to use a t-power circuit. what would be the disatvantage? sure, it would come with less gain to the pre, but would that mean more/too-much noise? I have to say that i am no electrition, I have to find some-one to make this for me, so I want to keep it as simple and cheap as possible. I don't know if any of you guys can help me. Thanks Fabio T-POWER: pre mic 2 o---+---------------100uF------+-------o 2 + | | 3 o---)---+-----------100uF------)---+---o 3 - | | | | 1 1 | | 0 0 | | K K | | | | | | +---+---1K5--+----+--2K2---+ | | | | | 47u 10u Z 2 | | 9 K | | V 2 | | | | 1 o--+------------+----+------------+ PS: I have to add an english-spell-checker to my email-program lol.....excuse all the errors

pulseaudio-module-jack realtime issue

by Brian Bergstrom

Hey all, I am experiencing some clicking/popping noises when running Jack on my both my internal and external USB interface. Oddly this did not coincide with the usual culprit, XRuns. I tracked it down to some errors in the system logs. Dec 23 23:10:37 defiant pulseaudio[4011]: module-jack-sink.c: JACK error >Cannot use real-time scheduling (RR/75)(1: Operation not permitted)< Dec 23 23:10:37 defiant pulseaudio[4011]: module-jack-sink.c: JACK error >AcquireRealTime error< Dec 23 23:10:37 defiant pulseaudio[4011]: module-jack-source.c: JACK error >Cannot use real-time scheduling (RR/75)(1: Operation not permitted)< Dec 23 23:10:37 defiant pulseaudio[4011]: module-jack-source.c: JACK error >AcquireRealTime error< Looks like pulse is having trouble with realtime permissions/scheduling?? I am fairly new to the pulseaudio-module-jack package(Ubuntu) that supplys module-jack-sink and module-jack-source for Pulse/Jack integration. Any help is appreciated, Brian

[ANN] MusE 2.0alpha

by Robert Jonsson

Hello everybody, We have a present for you, a new release of MusE. The alpha indicates this is an early version so it's mainly - a teaser to spread the word. - an early adopters build. - to welcome developers who want to port MusE to other platforms. MusE has now been completely ported to the Qt4 architecture and we (mainly Tim and Orcan) are busy to make it even better than before, lots of gui stuff being reworked. MusE now also sports a new version of the DeicsOnze, DX11 emulating softsynth, up from version 0.2 to 1.0. The homepage has received a new look that we hope will give a better indication of what MusE is and does. Do visit http://muse-sequencer.org. The full changelog is available at: http://lmuse.svn.sourceforge.net/viewvc/lmuse/trunk/muse2/ChangeLog?revisio… Find the download at: https://sourceforge.net/projects/lmuse/files/ Happy Holidays!

q: percussion piece

by Kim Cascone

I'm working on a percussion piece where I've generated the score by hand, then had a percussionist perform all three parts (instruments) of the piece into a midi file. I've got a library of around one hundred or so samples I designed that I want to experiment with i.e. arbitrarily select samples to play in order to build a little percussion ensemble for the piece. What I'd like to do is have ONE program (if possible) where I can import the .mid file, create a multi-sample instrument (yes like a drum kit) and assign any of my percussion samples to the key/note being played where I can tune, pan and adjust volume for each key/note. I'd prefer to do it all 'under one roof' if at all possible. I looked into LMMS but don't think it really does what I need it to -- besides, the LMMS documentation is very poor - so it turned me off to researching it further. Can any one point me to a simple one app does all environment on Linux where I can simply import a mid file and make a multi-sample instrument? I haven't worked with midi since my Silicon Valley days so I haven't been paying much attention to midi tools in Linux. Any help is appreciated. thanks in advance! KIM
