[linux-audio-user] FreqTweak 0.5.2 released

by Jesse Chappell

Version 0.5.2 of FreqTweak has been released. This is a feature (and bugfix) update: * added Compressor module * added EQ Boost module * now supports FFTW3 * fixed dialog closing problem, made them real windows * fixed compile problems for gcc 2.96 * manpage contributed by Enrique Arnuncio http://freqtweak.sourceforge.net ======================================================================= FreqTweak is a tool for realtime audio spectral manipulation and display. It provides several algorithms for processing audio data in the frequency domain and a highly interactive GUI to manipulate the associated filters for each. It also provides high-resolution spectral displays in the form of scrolling-raster spectrograms and energy vs frequency plots displaying both pre- and post-processed spectra. ======================================================================= If anyone has any cool ideas for new tweak modules, please subscribe and post them to freqtweak-user(a)lists.sourceforge.net.

[linux-audio-user] Two sound cards, only sound out of one

by Erik de Castro Lopo

Hi all, I asked this question on the alsa-user list but haven't received a reply so I thought I would ask here. I have two ENS1371 based cards plugged into the one machine: root@sound:~# cat /proc/asound/cards 0 [AudioPCI ]: ENS1371 - Ensoniq AudioPCI Ensoniq AudioPCI ENS1371 at 0xa400, irq 10 1 [AudioPCI_1 ]: ENS1371 - Ensoniq AudioPCI Ensoniq AudioPCI ENS1371 at 0x9400, irq 5 I have also set up a /etc/asound.conf file containing aliases for the cards named "card0" and "card1". I have also run alsamixergui with "-c 0" and "-c 1" parameters to set up output volumes on the two cards (and the controls on the two alsamixergui instances behave independantly). However, when I playback a sound file using: aplay -D card0 a.wav aplay -D card1 a.wav Only card0 produces sound. I have also tried physically swapping the cards but only card0 produces sound. I have also tried the -v option to aplay to confirm that the output is going to device 0 and device 1. I'm out of ideas about this. Does anybody have any hints on how I might get this going?

[linux-audio-user] building noteedit -- how to set KDEDIR, QTDIR

by James Jones

OK. The noteedit docs say to set the environment variables QTDIR and KTEDIR to the "path to your Qt installation" and "path to your KDE installation" respectively. Those don't appear to be set by default, and looking around on groups.google.com turns up a thread that says KDE no longer uses KDEDIR or KDEDIRS, but instead there's a program called kde-config that should be used instead. From running "rpm -ql qt" I'm guessing that I should set QTDIR to /usr/lib/qt-3.1, but it's rather less clear what I should set KDEDIR to. Looking around for kde-config options, I infer that KDEDIR should be set to what kde-config --path ??? outputs where one of the possible "type" values replaces ???, but it's not clear to me, even after looking at the configure script, what the intent is. Any help would be appreciated. (Also, shouldn't the configure script be changed to use kde-config itself, if KDEDIR is obsolete?) James Jones

[linux-audio-user] Audigy 2

by Joerg Anders

Hi all! Some time ago I asked at this list whether Audigy 2 soundcard works with hardware sound generation. The answer was: "Yes!" Today I tried: sfxload 8mbgmsfx.sf2 A soundfont which always worked with SB AWE 64. But surprising: The command works only 1 second. The tse3play -list detects 7 MIDI devices: ------- Port number: 63 Type: ALSA MIDI port Name: Receiver 63:0 ------- Port number: 64 Type: ALSA MIDI port Name: Audigy MPU-401 (UART) 64:0 ------- Port number: 65 Type: ALSA MIDI port Name: Audigy MPU-401 #2 64:32 ------- Port number: 66 Type: ALSA MIDI port Name: Emu10k1 Port 0 65:0 ------- Port number: 67 Type: ALSA MIDI port Name: Emu10k1 Port 1 65:1 ------- Port number: 68 Type: ALSA MIDI port Name: Emu10k1 Port 2 65:2 ------- Port number: 69 Type: ALSA MIDI port Name: Emu10k1 Port 3 65:3 I can play via all of these 3 devices with diffenet MIDI players. But unfortunataly I can't hear anything. I tried all rulers on alsamixer and deleted the "M" symbols on to of these rulers: Nothing helps. Any sugestions? Should I run "sfxload" with a certain option? -- J.Anders, Chemnitz, GERMANY (ja(a)informatik.tu-chemnitz.de)

[linux-audio-user] . Re: Animatronic parrot solution?

by Jonathan Segel

lee suggested PD, i would suggest SuperCollider. i have written many supercollider patches to do this sort of thing, but these are all in Mac - i'm still getting to the point of compiling SC in linux in my "free time" (tm). (though closer now, with debian unstable +alsa running on an older ppc!) anyway, in either app: one continuously running loop that tests (say every 0.1 second) for an input volume threshold, which, if crossed, starts a timer and starts writing to a buffer. my SC versions write start and stop sample numbers into an array to be accessed later. second, a loop that tests if there any sample in the buffer, and plays back accordingly, at rate*2 or whatever, or fft i guess if you want to shift pitch and not rate. third a loop that plays the default sample if nothing else is playing.. hope that helps somewhat... -- _________________________________________________________________ Jonathan Segel -- MAGNETIC -- PO Box 460816 S.F.

[linux-audio-user] jackEQ: dj eq and meter.

by Patrick Shirkey

For those of you who are interested in dj tools or tools for live performance, Steve Harris has made a new plugin called DJ EQ which is a three band EQ commonly found on dj mixing consoles. It's currently only available in the snapshots directory. You may also be interested in a new app we are creating based on the code from JAMin. It's called jackEQ. http://sf.net/projects/jackeq. No webpage yet and only cvs. It is in its infancy but it already connects to JACK and has a one channel (multiple i/o via qjackconnect) EQ and meter. I would like it to be able to do all these things eventually: unlimited channels. jack port connection ala freq tweak style route signal to monitor if monitor button is toggled for channel independant monitor gain control (with meter) and output to alternate alsa_pcm:outs With the above I could use my four channel card as a complete djing tool . You could also use a two channel card in a similar (mono) way. The monitor will be assignable to seperate output channels than the main outs. All the channels can be routed to it if needed. The eq's are all adjusted before the signal arrives at the monitor. This is how I intend to use it: mon ch1 ch2 ch3 ch4 echo ardour | |----------------| | out1&2 out3&4 internal internal If you are interested in contributing please join the mailing list. -- Patrick Shirkey - Boost Hardware Ltd. Http://www.boosthardware.com Http://www.djcj.org - The Linux Audio Users guide ======================================== Being on stage with the band in front of crowds shouting, "Get off! No! We want normal music!", I think that was more like acting than anything I've ever done. Goldie, 8 Nov, 2002 The Scotsman

[linux-audio-user] Animatronic parrot solution?

by Daniel James

Hello all, I've been asked by an animatronics technician for suggestions as how they might go about solving a particular problem with a robot parrot at a local theme park. The robot's voice feature was designed around a PC/Windows platform using Cool Edit Pro and scripted in Visual Basic. The idea is that you say something to the parrot, it pitch shifts your voice then repeats what you said two seconds later. If no-one talks to the parrot for a while, it says "hello, my name is Sancho, talk to me". Needless to say, they are having severe reliability problems with Windows as it is being used day in, day out. Can anyone suggest a suitable Linux solution for this parrot? I was thinking about ecasound combined with a pitch shift plugin, if one exists. If the solution could run entirely in RAM (CD booting, perhaps?) then that would solve the problem of hard disk reliability. Thanks Daniel
