[linux-audio-user] Jack module-playing fun

by janne halttunen

Hi all, despite of my hunt with google, I just couldn't find any module-player with jack-support. So, I wrote a small script. The xmp module-player allows for playing individual tracks from a module-file, and ecasound gives them out to jack. Yeah, it is an ugly hack, (better would be jack-support to xmp) but it sort of works (though not perfectly: connecting ports is slow). --cut-- # python jmp.py --help xmp.py options: usage: xmp.py [options] module-file -b, --buffer set buffersize -r, --rate set sample rate -c, --channels override number of channels -l, --looping loop module -n, --noconnect don't connect jack-ports to alsa-playback -q, --quiet -v, --verbose NOTE! external programs required: Extended Module Player: http://xmp.sourceforge.net/ Ecasound: http://eca.cx/ # python jmp.py /home/janne/biisit/drumble.xm --looping Jack Module Player v0.1a connecting ports........done. # jack_lsp alsa_pcm:capture_1 alsa_pcm:capture_2 alsa_pcm:playback_1 alsa_pcm:playback_2 ecasound:xmp_1 ecasound:xmp_2 ecasound:xmp_3 ecasound:xmp_4 ecasound:xmp_5 ecasound:xmp_6 ecasound:xmp_7 ecasound:xmp_8 --cut-- Get it here: http://www.pp.htv.fi/jhalttun/jmp.py cheers, janne

[linux-audio-user] [admin] list policy, non-member posting

by J�rn Nettingsmeier

hi everyone ! lately, the number of posting attempts from non-members has risen to a point where i'm just rejecting them without reading each one and checking if it's on-topic or has already been sent to the list from another account. our current list policy is members-only posting, for the following reasons: * i believe people who want to profit from a community should take part in it * spam prevention. so far, it has saved everyone from about .5k spam msgs. a number of list subscribers seem to post from different addresses, so some of their mails are being rejected. if this applies to you, there is always the possibility of subscribing multiple addresses and disabling mail delivery for all but one via the web interface. best, jo"rn -- J�rn Nettingsmeier Kurf�rstenstr 49, 45138 Essen, Germany http://spunk.dnsalias.org (my server) http://www.linuxdj.com/audio/lad/ (Linux Audio Developers)

[linux-audio-user] Triyng to compile pd (PPC)

[linux-audio-user] playing chords to help practise improvisation

by Peter Jay Salzman

hi all, i just started to play around with jazz improv. what would be really useful is if i can define a set of chord changes: Dm7 G7 Em7 A7 Am7 D7 Abm7 Db9 and have my computer play it over and over again so i can improvise over the key changes. it would be great if... it can loop: so i don't have to record the progression 100 times if i want to play around with this 100 times. the timing can change wildly: i can't really do much at the speed which i normally play "satan doll". the chords come too fast. and it's hard playing chords unnaturally slow (although i suppose that might be a good thing to practise). there were some kind of quarter note percussion that gives me a beat so know when the chord is about to change. it doesn't need to sound good at all. my improv should sound good. ;) is there an app i can use for this purpose? pete -- Fingerprint: B9F1 6CF3 47C4 7CD8 D33E 70A9 A3B9 1945 67EA 951D

[linux-audio-user] Re-encoding Stereo mp3's into Mono mp3's

by Steven P. Ulrick

Hello, Everyone :) My question is, is it possible to take an already existing mp3 (128 kBits, 44.1 kHZ, joint stereo) and re-encode it so that it is in mono (at 128 kBits of course). I figured out how to accomplish this task by using the command mpg123 -w to convert the mp3's into wav files, and then I use the following command to encode the wav file into a mono mp3: lame -b 128 -m mo (In both cases, of course I used the appropriate file names, in the appropriate order) What I would like to do, is re-encode the stereo mp3's directly into mono, without having to go through the time consuming step of converting the mp3's into wav files. In case you were wondering, one of the reason I want to do this, is that I have some old gospel songs from the early to mid sixties, and, like a lot of music from that era, the stereo is really cheesy: for example, almost all the instruments in one channel, and all the vocals in the other channel. This example is a bit extreme, but if you've ever heart "Left My Sins Behind Me" by the Alex Bradford Singers, you'd see why I want to convert to mono :) Thanks in advance for your help :) Steven P.

[linux-audio-user] Hammerfall HDSP 9652 Installation

by Mark Knecht

Hi, My new Hammerfall HDSP 9652 arrived. (The new PCI card, not the DigiFace/MultiFace configuration.) The Alsa Card Matrix says it's supported, but the version of alsaconf (0.9.0-1) installed on my system does not recognize it. Questions: 1) Does a newer version of alsaconf support this directly? 2) Can that version of alsaconf be installed without changing the version of Alsa that I'm using? (I'm rpm based from the Planet and don't want to break dependencies if possible.) 3) Is there a simple, straightforward way for me to install Alsa support for this card by hand? If so, where might I find the instructions? Thanks in advance, Mark

[linux-audio-user] Clicking noises - how to get rid of?

by Pauline Powledge

Greetings, I am trying to convert some old cassette music to audio CD format. I'm very new to Linux audio, mixers, and so forth, and have some newbie-type questions to ask. I'm running the 2.2.14 kernel with the ALSA drivers, version 5.12a, es1968 module, with an es 1978S soundcard. The problem I have is that I get a loud, persistent, evenly-spaced clicking sound in my input. My mixer is set up with 100% volume, unmuted, and captured on the MIC input, and 20% volume, unmuted, on the Input Gain. Everything else is muted. I have tried running ecasound with "-r -z:nointbuf", but that doesn't seem to help. The dropouts are so consistent -- almost like a metronome -- that I'm not inclined to think this is a latency issue, so I doubt patching the kernel will work. I do my recording with X Windows off and my 802.11B card out. Does anyone have any suggestions about what I ought to try next? When I searched the archive, I saw mention of a problem of persistent clicking with another soundcard that was solved by going from a 2.2 kernel to a 2.4 kernel. Is that a known issue with other soundcards too? Thanks in advance for any clues, Polly

[linux-audio-user] metronome apps

by Dave Phillips

Greetings: Yesterday I wanted to practice with a metronome, so I decided to download one of the listings from the Linux Soundapps pages. Alas, I got no joy: 1. cmetronome's server is unavailable 2. gTick wants to use /dev/sequencer and isn't working for me with ALSA 0.9.0beta10 3. gMetronome is a visual-only metronome and I need sound So I went looking for something else. I found Metronome on SourceForge, but its based on gTick and suffers the same poor output. I also found DiffM, a Java-based metronome that is said to work under Linux, but the available package only works with MacOS. So I still don't have a metronome, and I don't feel like compiling Ardour just to use it as a practice amenity. So, does anyone have a lead to a working software metronome for Linux ? Does anyone have the sources to cmetronome ? Or is anyone interested in writing a simple metronome application ? Back to the hack...

[linux-audio-user] chebstortion in swh-plugins: How *should* it sound?

by Frank Barknecht

Hi, I played a bit with chebdistortion from the SWH set, and I'm wondering, if what I get is the intended result. I doesn't sound like an effect useful for anything to my ears, but I might have a broken version or something. I made an short example at http://footils.org/snd/cheb.ogg with a clean signal, then the chebdistortion kicking in. Is it intent this way? ciao -- Frank Barknecht _ ______footils.org__

[linux-audio-user] CD covers & booklets

by Howard Sanner

I've been trying to use Kover 0.8.4 to create CD tray cards, and, more importantly, inserts. This is the latest version of Kover I could find that does not require KDE 3.0. I'm using 2.2.1 under Mandrake 8.1. The problem I haven't been able to work around is creating the INSIDE of a CD booklet, i.e., pages 2-3. I can get it to put the title on the RH panel and a contents list or whatever I want on the LH panel. However, I can't start on the LH panel with the inside of the booklet and have the text wrap around to the RH panel. Does anyone have ideas? Is there a better program out there for doing this? FWIW, none of this stuff can be downloaded from an Internet database; it's all recordings of live opera performances. Thanks for all suggestions. I realize this is not the main emphasis of the list, so please feel free to reply privately. Howard Sanner flagstad(a)mindspring.com
