[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

[linux-audio-user] RT Sound manipulation (aka effect rack :)

by Adrian Gschwend

Hi all, My cousin is working in a company that does a lot of audio/video streaming solutions based on Linux systems. Now they look for an application which provides similar things like SOX but in real time. They would like to record on the input, manipulate it via GUI (Eqalizer, effects...) and send it directly to the output. Are there any recommendations for this kind of Linux software? thanks Adrian -- Adrian Gschwend @ netlabs.org ktk [a t] netlabs.org ------- Free Software for OS/2 and eCS http://www.netlabs.org

[linux-audio-user] ardour building bugs

by Julien Claassen

Hello! I just discovered two problems with ardour: 1. If you run the autogen script the -gui and -ksi options are exchanged. Where it says -gui it says something like libs="libs_base ksi" and in the ksi-case it wants to include the gui-libs. 2. The next thing something running ardour-ksi. I've jack-0.7.3 and I seemed to fullfill all the other dependencies. But now when I try to start ksi it says: /usr/local/lib/ardour/ksix: relocation error: /usr/local/lib/ardour/libardour.so.0: undefined symbol: _ZTI8QMThread So and that's all. this ardour version is from tuesday morning. Any ideas about the second problem?

[linux-audio-user] Developers: how to sync PCM to Midi?

by Denis de Leeuw Duarte

Hello folks, I'm writing a realtime audio tool and I'd like to pick your brains on the following: say my app is rendering some sound and a midi event comes in, at what point in time should the resulting effect occur in the rendered audio stream? The obvious solution would be to measure world/system time at the moment playback is started in my application. If a midi event then comes in, I can subtract this start time from the midi event time. I am however afraid that my timing will then drift each time an underrun occurs. I'm pretty sure applications like terminatorx, sweep and a host of others solved this problem before me so if anybody knows the answer to this, please let me know! Regards, Denis p.s. I use JACK for audio output but the solution really should be independent of this. --------------- www.cyozlab.com _________________________________________________________________ MSN 8 helps eliminate e-mail viruses.
