[linux-audio-user] Old hat - comparison against windows

by Michael Ost

Can anyone suggest ways to compare audio/midi performance between Linux and Windows that (1) are relevant to non-technical musicians and (2) make Linux compare favorably? Not things like "I just don't like Windows" or software feature comparisons or the politics of open vs. closed source, but rather things like responsiveness to audio interrupts, RAM footprint of the OS and ...? I work for a company that sells a Linux based piece of hardware that plays windows VSTs. We spend alot of time on compatibility, especially on getting the plugins to work with Wine. I often get asked about switching to Windows and I don't have a good answer. My sense is that the main benefit of Linux is that audio interrupts are serviced faster and more predictably than in Windows because of SCHED_FIFO and Linux's low overhead. And clearly musicians could feel that, especially at lower buffer size settings so that's the kind of thing that could matter. But is it _really_ true? Is there a standard way to measure it? Or published results about it? Are there any other things to compare? Thanks for any input. I _want_ to believe! %) ... mo PS: apologies for any confusion that comes from posting to both linux-dev and linux-user. I wasn't sure which list this is more appropriate to...?

[linux-audio-user] Nmmm nmmm (yawn)

by Folderol

Another late night (early morning). Yet another tune that had to be finished over the weekend ... ish! I actually started working on it a few weeks before I started on East To West but hit a creative block, so put it to one side for a while. One problem I had was getting a soft drum sound. This was something I couldn't find in any of the hydrogen kits, nor in the drumsets on THREE different hardware synths. The drum I wanted to emulate is, I think, Irish in origin. It is a hand held drum and the single stick is double ended and leather padded, looking something like a dog bone. Eventually I was able to create something like it in Zyn. I also wanted a shaken tambourine and this seems just as hard to find. I used a combination of effects in Zyn. to get somewhere near it, but it isn't really right. Anyway, the results so far are on: http://www.musically.me.uk/music/Celtic_Dream.ogg http://www.musically.me.uk/music/Celtic_Dream.mp3 -- Will J G

Don't forget that Ubuntu is based on Debian "unstable". The nice things in Ubuntu actually come from Debian - it's just that these things have taken a little while to get through to Debian testing or stable. My preference always lies at the sign of the red swirly thing, Ubuntu always seems to have a problem somewhere (just my experience from a while ago). > > At the other Hand: a distro is as good as the softwarepackages that > can be installed upon and as one can install Debian-Packages on buntu > and vice versa, it turns out to be a matter of personal taste, what > becomes you best.... Debian & Ubuntu are *not* always compatible & interchangeable: Ubuntu is based on Debian but many things are recompiled for Ubuntu. A friend of mine trashed an Ubuntu installation by trying to add apps from Debian & DeMuDi. I would have to say that you should always ask yourself the following question if thinking of cross-installing Debian & Ubuntu packages: the question is "do you feel lucky?" Gavin.

[linux-audio-user] DeMuDi status? Distribution for gig synth?

by Larry Troxler

Now that demudi.agnula.org seems to have been taken over, is there any other site that has a copy of this distribution? Is it wise at this point to continue using it? I just recently installed it, so I'm not overly comitted to it yet. I'm looking for a distribution that would be suitable for a rackmount PC-based synthesizer that I can take to occasional gigs. DeMuDi seems to fit the bill, because it is nice and trimmed down, as opposed to (I suspect) Planet CCRMA. Larry

Is archive.org the best/only free resource for storing CC licensed tracks? Thanks! Jon Hoskins

[linux-audio-user] sdif enabled apps

by Alex

Does anyone know of any linux apps that use sdif? Anything that synthesizes from sdif, allows for manipulation of the data, visualization of the data? Thanks, Alex

[linux-audio-user] live recording event advice

by H.S.

Hello, I have been asked to organize/setup a recording system for a community event that will involve recording a single session of around three hours every day. The audio consists of some speaches and some live music and singing. It is a volunteer effort and I suppose they do not have much funds to invest for this recording setup. They already have a 2.5 GHz computer with 512 MB of arm (I can use the computer in whatever way I deem necessary), a bunch of older computers (maybe around 500 MHz with 256MB RAM lying around), a 12 channel mixer which has around 4 or 6 mics connecteted to it and an amplifier. Here is my first tentative idea. Split the Sub R and Sub L output of the audio board (currently they are connected to an amplifier) and take one part of both of these channels to the Line In of a computer (and the other parts go to the amplifier). Install Ubuntu (or maybe another distro) and use Audacity to do the recording (I am more familiar with Linux, haven't considered Windows yet). I understand that in Audacity I can specify the duration of the recording. So it appears that it won't be difficult for anybody to start Audacity, type in the duration in the "duration window" (say, 3h00m00s) and press "record". Hopefully, Audacity can be set to record directly to ogg format. This way, I won't have to be present there all the time to start or stop the recording and also won't need to post process the audio to get it into ogg (if it were recorded in Wav to begin with). I haven't done this kind of a project before. I am assuming: 1. The outputs Sub R and Sub L are can be directly connected to a Line In of an audio device 2. The PC I mentioned above would be sufficient to do live recording and encoding without any problems. 3. Audacity is appropriate for this project. 4. The computer's line in would be sufficient for a fine quality recording. Having said this, I would sure love to have some advice from experienced users. Also, I need to buy these connectors and cables: - 1/4 in. mono pins to two RCA connectors (Y connector), - a two RCA to 1/8 in. connector (Sub RL -> Line In of comp.), and - RCA-RCA connector(Sub RL RCA -> amp.). Any recommendation for a good place (I don't want the quality of the audio to suffer just because of low-quality cables)? Also, any suggestions on how far can I take the recording computer from the audio board's outputs (cable length problem). And, if a Line In of a computer is not good enough, which sound card should I look for? Thanks, ->HS

[linux-audio-user] Multi-channel audio with a computer front end

by Bearcat M. Sandor

Folks, I will be building an audiophile/home theater system soon. I'm starting with 2-channel and want to make my way up to 4 (i don't like center channels). I'm using my computer as the front end. I'd like to use USB, Firewire or wireless as my "transmission lines". As far as multichannel goes, i'd imagine that even if i split audio into front and back and sent each to a wireless Slim Devices Transporter ( http://www.slimdevices.com/pi_transporter.html) that the two tranporters would not be in synch. So, is a firewire device like the Apogee Rosetta 800 a solution? Will a linux movie player using xine or gstreamer be able to send the correct channels of the Dolby Digital/DTS to the individual channels on a multi-channel pro device? This all assumes that Freebob (the firewire driver) works as advertised. I realize i can just send a dolby digital/DTS signal to the Transporter and then on to a pre/pro but that adds another link in the chain. Thanks all.

[linux-audio-user] scripted cat of wavefiles

by Atte André Jensen

Hi I'm in the process of making a cd with my linux based compositions. I'd like the compositions to float into each other with small atmospheric interludes. I make interludes and compositions as separate wave-files that needs to be spliced together. Since they are still redone all the time, I don't feel like chaining everything together by hand, lowering volume of interludes (that are normalized) and making markers for cd tracks just to get a demo-snapshot of everything. Is there a tool out there that will do this for me, or should I simply write a small script in python? -- peace, love & harmony Atte http://www.atte.dk | quintet: http://www.anagrammer.dk | compositions: http://www.atte.dk/compositions
