[linux-audio-user] tool for bass testing

by Bryan Koschmann - GKT

Hello, I have a few friends that are heavily into their car stereos with the heavy bass. They have all sorts of CDs (bass mechanik?) that have some cool techno loaded with some heavy hitting low frequency bass. This got me curious, and since I can't find anything on Freshmeat or Google (or just am not using the right terms) I was wondering if anyone here knew of such a program that can generate some nice smooth bass. I have played with one of the drum editors (the popular one? cant remember the name) but of course it didn't seem to have any lower frequency generating drums. If anyone could point me to something like this I would be greatly appreciative! Thanks, Bryan

If I'm able to listen to a previously recorded drum track and record a guitar track over it (in sync with the recording) with either card, how is it possible for them to be out of sync with each other? | As for the Drum kit, I know it is desireable to | record many channels of drum separately, but would | it do to simply use say a Mackie 1402-VLZPro mixer | to funnel the drum mics into two or three channels? | You would have to get the mix right the first time, | I know, but the 1402 would give you six very nice | channels of mic pre, which should ease the budget | problem. You also get phantom power, which you must | not forget that you need to power any decent condensor | mic. I'll consider this, but my original plan was to spend my money on getting the best soundcard, preamps, and mics and doing as much as possible in software. The idea was to get the highest quality crucial hardware i could afford, and do any and all mixing, processing, etc, in software (which is putting a lot of faith in linux ;) ).

I'll end up with at least an sm57 or sm58 (or comparable) for starters.

[linux-audio-user] linuxtag 2003 resume

by Joern Nettingsmeier

hi everyone ! i'm just sitting in train up the beautiful rhine valley on my trip back from this year's linuxtag, where we had a joint booth for the alsa project and the linux audio developers. it has been great fun, and i think we made some impact :) the linuxtag page at http://www.linuxdj.com/audio/lad/eventslt2003.php3 has some more information, and will be updated with more photos and recordings as i get them. if any of the booth participants has something to add, i'll be glad to include it. thanks to frank neumann who organized our booth for the third time, and kudos to the linuxtag organizers and especially martin "joey" schulze for creating a unique and very inspiring linux event. i'd also like to thank all the LAD folks who lurked on #lad ready to answer questions from booth visitors, but due to network failures and an extremely crowded booth, this did not happen as planned. we'll be back next year. regards, jörn -- All Members shall refrain in their international relations from the threat or use of force against the territorial integrity or political independence of any state, or in any other manner inconsistent with the Purposes of the United Nations. -- Charter of the United Nations, Article 2.4 Jörn Nettingsmeier Kurfürstenstr 49, 45138 Essen, Germany http://spunk.dnsalias.org (my server) http://www.linuxdj.com/audio/lad/ (Linux Audio Developers)

[linux-audio-user] Success stories

by Robert Jonsson

Hi guys and gals, A friend of mine has been doing some very serious attempts at producing music with a fully linux based setup lately. There has been lots of pitfalls along the way, but since he is a _very_ dedicated guy he has come a long way towards pulling of his goal. The goal in question being to produce an "album" purely in linux. (album in the sense that the songs are freely downloadable from the same web page on the net, i think ;) ) He has just started to document the thing, you can have a look here: http://computerville.homeip.net/linuxmusic/, there are also some samples of what he has produced this far, in my opinion it shows that linux audio is getting 'there'. Have a nice weekend, Robert

[linux-audio-user] A dumb Unix question about console output

by Larry Troxler

Hi, I hesitate to ask this here, since it's gotta be a basic shell thing, and certainly not audio specific, so if you want to flame me for me OT and laziness, go ahead. The problem is that when I run I run an X application from a console (for example, "pd &" or "rosegarden &", the console output from all the applications I run are interleaved onto the xterm that I started them from. That part is fine. The part that is not fine, is that the output is not labeled with the application that it came from. For example, I seem to remember that if in the past, if you ran grep, for example, anything that grep sent to its console would be prefixed by "grep:". I thought that this was a convention that the apps followed, and not a shell thing (I seem to remember "printf("%s: ...", argv[0], ....") Hopefully, I'm wrong about this, and there is a shell option that puts the application name in front of every line of output. Is there? If it's not something I can make happen in the shell, then how is everyone dealing with this? Currently I am actually opening a seperate xterm for each X application that I run, which is quite cumbersome, because it means that I have to manage twice minus one as many windows as I would if I could have all the output into one xterm, identified with where it came from. Looking forward to any ideas and any pointers to my misconceptions. Larry Troxler

[linux-audio-user] Re: linux-audio-user digest, Vol 1 #564 - 12 msgs

by Peter Groves

Thanks for such an in depth explanation. Today will go down as one of those days I actually learned me somethin. | > I don't understand this whole 'drift' thing. If I'm able to listen to a | > previously recorded drum track and record a guitar track over it (in | > sync with the recording) with either card, how is it possible for them | > to be out of sync with each other? | | Peter, | It's easy for people to not see this problem the first time they look at | it, but it's usually not that difficult to explain, given a bit of basic | engineering background. | | All of these sound cards have oscillators on them to allow them to sample | and playback at a given rate, such as 44100 Hz. the problem is that no two | oscillators (or the crystals that drive them) produce EXACTLY 44100 cyles | per second. They are spec'ed to be within a certain tolerance, like 1%, or | +/- 100 parts per million, but the point is that they are not creating | exactly the 'right' number of cycles per second. | | With this in mind, if you have two sound cards (same models, different | models, it doesn't matter) and they run from separate clock sources, then | one of them might be operating at 44099 cyles per second, while the other is | operating at 44101 cycles per second. If this was the case, then (in | differeing by 2 cyles per second) after 22050 seconds they would be out of | sync by one complete second. (The slow one would be one second behind.) | Since the human ear can pick up very minute differences in time, the effect | becomes noticible much more quickly than that though, and unfortunately, | most crystals will be much further off than 1 cycle per second from the | spec. | | The reason you can play the same track back, over and over, and even on | different sound cards, is that while 44100 samples 'represents' on second, | it may not 'take' on second to play back. You ear is pretty insensitive to | the idea that a song played on your CD player in the house takes 3:49.203 | seconds, while in the car it might take 3:49:542 seonds. We are just not | sensitive enough to hear that, although the pitch in the house would be | measureable as slightly higher. | | All this said, it is NOT true that you cannot use two (or more) sound | cards at the same time. You can, but they have to be clocked from the same | clock. you can accomplish this on any pair of sound cards that support the | Word Clock interface, and I've been able to do it over ADAT interfaces with | multiple cards, but that's not for the uninitiated. ;-) It's harder to set | up. | | I hope this helps clarify the physical reasons that this is difficult. | | There is a software reason also. Linux/Alsa will onlt interrface to a | single clock, so clocks being generated by two sound cards are not something | that Alsa is designed to handle. | | Cheers, | Mark | | | | | --__--__-- | | Message: 7 | Date: Sun, 13 Jul 2003 13:35:33 -0700 (PDT) | From: Brian Redfern <bredfern(a)calarts.edu> | To: linux-audio-user(a)music.columbia.edu | Subject: Re: [linux-audio-user] Success stories | Reply-To: linux-audio-user(a)music.columbia.edu | | Well, I use Swami to build my own sound fonts, I have some quite gritty | ones, cause my old band-mate is the producer for The Freestyle Fellowship | (if you haven't heard of them, they've been the underground legends of Hi | Hop for 12 years now). | | Anyways I find Csound to be the tool of choice for serious composition in | a linux only environment.

[linux-audio-user] Multiple (delta xx) cards

by Peter Groves

Here's some brief background before I get to my question: -I'm building a linux daw from scratch (including external hardware) -I've just put together a dual athlon 2400+ machine and have (tentatively) installed mandrake -I'm running out of money *fast* The third point has put a damper on my soundcard/preamp/mic plans. Initially I'll be happy to just record 1-2 channels at a time, but my goal is to be able to do a decent job with a drum kit, possibly with guitar or bass at the same time. I figure I can squeeze that in to eight channels. Ideally, I'd like to be able to buy a delta 44 now (for financial reasons), and then buy another, or possibly a 66, later on and add it to the set up. If I do this I can get a decent mic and preamp. Otherwise, I have to go with the 1010 now and use a $20 radio shack mic until my bank account recovers. I checked around the lad archives and this question seems to come up from time to time, but I'm wondering if this is possible with what's currently out there. Thanks, Peter
