[linux-audio-user] how to build a studio?

by Joshua N Pritikin

i'm new to pro-audio world and i need some advice about how to setup a studio. i got my PC setup with an RME HDSP-9652 + SPDIF A/D D/A converter. Ardour works great. i'm planning to purchase a FocusRite OctoPre/ADAT and a bunch of microphones. i think i need speakers too. Is there anything like digital speakers or digital amps which can accept ADAT directly from my linux box and turn it into sound? Or do i need to convert ADAT to analogue and plug that into a conventional amp/speaker system? Considering how much care i'm taking to record sound digitally, without noise, it seems like i should also take care that the speakers can actually playback my recordings without too much distortion. Anyone have any recommendations? -- Victory to the Divine Mother!! after all, http://sahajayoga.org http://why-compete.org

I have recorded using both arecord and ecasound. I am reinstalling jack e.t.c.. with the aim of using Ardour, it seems there are succesful users of these devices there. > > I have a delta44 and I can only use it to play. > However the Vu-meters of envy24control shows a correct input level, but > how can I redirect this input toward a recorder, especially audacity ? As for audacity, I haven't really tried. Maybe someone else has used audacity with a Delta card.... I'll install it and give it a go -- Allan Klinbail <allank(a)labyrinth.net.au>

[linux-audio-user] Delta 66 and cd's : stupid question

by Allan Klinbail

Okay, Now that I have pretty much decided to give up the ghost on the intel8x0 as a hardware patchbay seems to be a better option, (and I think the onbaord audio system may have shorted .., the driver now refuses to load all setting are as they previously were) Has anyone got any suggestions regarding playing cd's while not doing audio work? (as there is no cd input on the delta66). Is there a player that will read the digital audio and send it to the sound card .. such as an unmentionable player from another OS? Or do I need to begin ripping and converting to mp3 (yuck) cheers -- Allan Klinbail <allank(a)labyrinth.net.au>

[linux-audio-user] NI Traktor

by Robert Jonsson

This is a first for audio applications. Native Instruments Traktor just appeared on Freshmeat! :) I guess some people are starting to take notice of the OSS community. Though it isn't OSS in itself and not available for Linux (OS X, + a few marginal os:es). But the most interesting thing was that they used Freshmeat as a marketing channel. /Robert

My first tip: spend money on room acoustics. (record a sinus-sweep and screen it. any omni will do.) this point is more important than what speakers you use, because speakers sound different in different rooms. You need a D/A-converter with balanced output and active monitors. active monitors have tech. advantages vs. the combination amp/passive speaker. i would go for gaithain speakers (all modells, 2000 - 5000 EUR), but this is matter of tast. tannoy reveal cost about 250 $. i dont recomend ANY genelec speakers or yamaha. i personally like reveal a lot, for me there is no competition in this price range. most important is that you get no 'bad surprise' when listening to your mix on hi-end monitors. even if reveal don´t sound so spectacular, you will have no such surprise with them. reserve most of your money for mics. what thing are you going to record?

[linux-audio-user] Can't get rosegarden4 to record from ALSA virmidi

by Larry Troxler

Has anyone got rosegarden to record from an ALSA virmidi port? I can't get it to work, and apparently nobody on the rosegarden list has tried it, so that so far, I have not got any answers there, probably because the developers are very busy with other things.. But I thought I'd ask here as well, because there may be some rosegarden users that aren't on their list, and I'm getting hungry to get this solved. I'm hesitant to submit a formal Rosegarden bug report just yet, because I could be misunderstanding something about the way virmidi works. In case anyone's interested, Rosegarden is a sequencer app that uses the ALSA MIDI sequencer API. What I'm trying to do is load a the virmidi device, and then aconnect 72:0 73:0 for example. Then I set up the record device in Rosegarden to record from 73:0, and set up a play track that plays on 72:0. Thus when I record, I would expect that events get recorded onto the record track, but it doesn't happen. I also can't record events to that track if I play them from PD, using the OSS compatilibilty interface, through a device that is symlinked to 72:0. However, PD itself has no problems linking the two devices together - Through PD I can play through 72:0 and have PD receive the message back through 73:0. It is entirely possible that I'm making some silly mistake, so that's why I ask here. Can anyone suggest some other test to try? Is it possible that there is a bug in ALSA where using the sequencer API doesn't work when getting events from a virmidi device? Or is it more likely a bug in Rosegarden? I already tried making sure that Rosegarden seem to be opening the correct record device, by hardwiring this in the source code. What's left next for me to try, is opening the 73:0 device in record direction only (Rosegarden I beleive is opening it in duplex mode). So, any thoughts? Is there some simpler application I could try as a sanity check, to see if my ALSA and virmidi are working? Larry Troxler

[linux-audio-user] Newbie/Laptop/Linux/Audio

by sh＠nnon.tv

I'm fed up with expensive upgrades and a dull computer experience so I'm making the leap from Apple. I've just built a bare bones Linux box with AMD 2600+/9700Radeon/120gig HD/ CD DVD RW/ etc and crammed it into a Shuttle box. Small and runs cool. Slackware is happy on it. I need to augment my audio computer needs with a laptop. I've looked around on the archives and have not found a consensus and would appreciate some help in this area. What works with Linux and audio best on a laptop? I've been looking at IBM T30/T40 used but don't know really what to get. thanks, Shannon

[linux-audio-user] Processor Recommendation

by Peter Groves

I'm planning on building a new machine and would like some advice. Right now I think the main application of it's "power" will be in recording/mixing in linux. People have been saying that a dual processor is something to consider, but there's currently a problem: the amd athlon's that would be at my price point (the 2600 - 2800's) have no dual processor motherboard support, and it looks like there won't be any b/c companies are just going to go straight to supporting the new 64-bit opterons (which aren't in my price range). So if anyone can comment on any of the following things, it would really help me out. Front Side Bus speed: how important is this for recording? i could just get two bargain athlon's with a slower FSB, would that work? Would any of the sound apps out there, or even linux in general, make any use of a 64 bit opteron anytime soon? (no i won't have more than 4GB of memory) Hyperthreading - the new fancy P4's have it. Does it do anything on linux? I saw some benchmarks where it really sped up video encoding (on windows), how similar to sound processing is this? In general, intel chips seem to do better in benchmarks on floating point stuff (games and video) while amd's do better on integer heavy apps (office software). I would think that sound stuff would therefore run better on intel's but lots of sound people say they prefer amd's. Any reason for this? How fast does a system really need to be before it can handle recording with practically no limits? (let's say fewer than 10 tracks at a time such as with a delta1010) thanks for any help, i'd be happy if i got responses to only a few of these questions. Peter

[linux-audio-user] [Fwd: audio card for linux]

by Dave Phillips

Greetings: I know that the RME HDSP card is probably what Oeyvind is looking for, but I thought that perhaps some users might care to share their experiences with it. Please cc any replies to him as well the list, thanks ! Best regards, == dp

[linux-audio-user] ALSA -> OSS mapping question for Delta 1010LT card

by Akos Maroy

I have a Delta 1010LT audio card. I have ALSA version 0.9.4 installed on a RedHat Linux 9. I want to record multiple, unrelated audio streams that overlap in time but do not necessarily stop and start at the same time. Imagine radios, each tuned to a different station, plugged in to each audio input on the audio card. I have an existing application, which uses OSS interfaces, which will do what I want if I can just configure ALSA to create a different emulated OSS sound device for each input channel on the sound card. (Or, perhaps for stereo pairs of input channels). So, is there a way to configure ALSA to do this, and if so, what is it?
