One thing I wanted to point out (that they taught us in the recording classes I took) was that in the (above) setup, it's important to put the mics in a "cross pattern" (like an X). The heads of the mics need to be 45 degrees apart from each other. If you don't then you can get "phase cancellations". It has to do with the the amount of time it takes sound to hit one mic and then the other. If the mics are _not_ at a 45 degree position, then they can be close enough to cause one mic to pick up the sound source and the other one to pick up the _same_ sound source (just milliseconds later). And when you have the same exact sound being offsetted by only milliseconds, you get "phasing". In fact, that exactly how you get the (guitar) effect they call "phasing".... by taking a sound and offsetting the same sound by just a few milliseconds. I think (if my memory serves me well) that the 45 degree angle isolates each mic to the point were it can't pick up the same sound in each mic. Actually, Jan may have some kind of knack for this thing, because we were taught that (the tecnique jan used) was the way to go if you only have 3 mics - (two overhead and one for the kick drum). In fact, I think Jan's choice to use condencers for overhead and sm57 on the kick is a good choice. But please trust me. If you don't do the cross pattern you (could) hear unwanted sounds (and/or dropouts). While I'm at it... that whole recording sounds great.

Hi John, Thanks, but I covered that. Any other suggestions?

[linux-audio-user] M-Audio Delta 44 / ALSA question

by John Bleichert

Hello All If/when I get my Delta 44, how are all the inputs and outputs mapped into/out of the system? /dev/dsp0 - /dev/dsp7? How exactly does this work? Does the driver for these cards provide any routing capabilities between the inputs and outputs? Any info appreciated. Thanks - JB # John Bleichert # http://vonbek.dhs.org/latest.jpg

Kai, Sorry. I forgot about ecasound. I haven't used it myself but from what I've heard it's the most stable multitracker around.

Ardour is *not* trivial to set up (check my web page > http://myweb.cableone.net/eviltwin69/ALSA_JACK_ARDOUR.html). Don't forget ecasound (w/ ALSA): ecasound -a:mon -i drums.wav -o alsa,default \ -a:rec1,rec2 -f:16,2,44100 -i alsa,default \ -a:rec1 -f:16,1,44100 -o first_rec_channel.wav \ -a:rec2 -erc:2,1 -f:16,1,44100 -o second_rec_channel.wav ... with OSS you just replace 'alsa,default' with '/dev/dep' and it'll work (assuming your OSS drivers support full-duplex). ... with JACK it's even easier: ecasound -a:mon -f:16,1,44100 -i drums.wav -o jack \ -a:rec1 -i jack -o first_rec_channel.wav \ -a:rec2 -i jack -o second_rec_channel.wav ... you'll have to use qjackconnect or jack_connect to connect the port to the soundcard ports. .. more examples at: http://www.wakkanet.fi/~kaiv/ecasound/Documentation/examples.html And ecasound *is* trivial to set up. :) -- http://www.eca.cx Audio software for Linux!

[linux-audio-user] problems with Midisport 2x2

by Ivica Bukvic

Hi all, I've got a small problem with my Midisport 2x2 MIDI interface. While it worked ok before, now for some odd reason I cannot get it to open for MIDI output (from the computer). I've checked the /var/log/messages and this is what I got: Feb 24 20:44:41 mycomp kernel: hub.c: USB new device connect on bus2/1, assigned device number 2 Feb 24 20:44:41 mycomp kernel: usb.c: USB device 2 (vend/prod 0x763/0x1001) is not claimed by any active driver.

Why is this the case? I have no problem getting the midi input going, but my output is mysteriously dead. I've read somewhere that if the device is reconnected that the output stops working (might have been CCRMA's Fernando), but this is the log from the initial connect as soon as the computer boots. I've also made sure that no MIDI devices were connected to the MIDISPORT upon starting up. Any help on this issue is greatly appreciated! Sincerely, Ico

RE: [OT] Re: [linux-audio-user] Pop filter?

by eviltwin69＠cableone.net

Gabon. You've made my point for me. It's not black and white. Saying "I'm not buying anything made in China because they're bad people" is way too simplistic. If that's the way you want to look at it then no one should ever buy anything made in China. Who then suffers the most? The people in charge or the people who used to make $1 a day? I appreciate people standing for a better humanity as well but that's not the way to go about it. It strikes me as self-serving and fatuous - "I quit buying Chinese products, I feel so much better about myself now". Jan Yes I 've been to Djibouti. Have you seen Madagascar, or "Cote d'Ivoire" (Ivory Coast in english?) . The way money came in didn't make people happier nor the land better (see corruptions, pollutions, largest ever ethnic wars). It's not all black and white (without pun), but it's certainly not all good and I appreciate people standing for a better humanity. Cheers all.

[linux-audio-user] Pop filter?

by Joe Hartley

I've got a vocal track that I recorded using ardour, and I have some serious pops in it from the singer being way too close to the mike and taking off my lovely pantyhose-over-a-wire-hangar-loop filter. I'm at a loss as to what filter/tool I might be able to use to reduce the severity of this... any clues?

[linux-audio-user] M-audio Firewire 410 ??

by kevin ernste

Has anyone seen or used this box, the M-audio Firewire 410? I have not seen it anywhere but on the page below, including M-audio's own site. Is it new or discontinued or what? It looks very promising. http://bayviewproaudio.com/maudio_firewire410.html Also, does anyone know the status of firewire and/or firewire audio in Linux. I realize most of the hardware (MOTU) is unsupported (unsupportive?). Kevin __________________________________________________ Do you Yahoo!? Yahoo!

[linux-audio-user] ZynAddSubFX 1.0.9 relased

by Nasca Paul

Hi. I relased ZynAddSubFX 1.0.9 (a very poerfull software synthesizer for Linux). News: - added keylimit to Part - you can use multiple filter stges in order to make very steep filter rolloffs (eg. 48 dB/octave) - ADsynth - added noise mode and you can make fixed frequencies; added the "Punch" parameter - added an external program "Controller" which enables you to use the mouse for MIDI controllers - other improvements and bugfixes See more at http://zynaddsubfx.sourceforge.net Paul. __________________________________________________ Do you Yahoo!?

[linux-audio-user] Linux Version Of FriutyLoops

by linuxmedia4＠netscape.net

Greetings, My 10 year old nephew and I were creating a video with Brodcast2000 and when it came to creating the music track he _insisted_ that we use FruityLoops. I don't have the nessesary Windows parts installed to allow Wine to do it's job. Is there a Linux equivelent? It doesn't have to have all the features of FruityLoops. In fact, if anyone can give me a hint how to get existing programs to emulate some of the features of FruityLoops, that would be great.
