You can get that out of the Alesis io|2, USB 1, duplex, 24 bit stereo, 48 kHz. It uses actual 24 bit sample format ... so that's 3 B * 2 * 2 * 48000 = 563 KiB per second of payload data that fits well into the limit of USB 1.1 (12 MBit/s = 1464 KiB/s), giving space for whatever overhead is present. But yeah, anything more than that gets really tight. You could have a card with 4 recording channels and 2 playback ... that would be 844 KiB/s ... but then, I don't know how much overhead you have with USB audio and also I'd have to review how duplex operation actually affects the available data rate. Also, looking at the devices that are there, USB1 audio for linux goes up to 24 bit stereo, duplex. And yes, USB 2 devices seem to be sparsely supported. For multichannel recording I got a FireWire device... and FireWire audio can be a bitch to get working right (building a good computer setup). Stereo cards work the best. There are a few multichannel cards that work too, but out of those, usually only those will work well that have specific drivers. The one that seems to work nowadays is the Edirol UA-101, the USB2-sister of my FA-101. There is a driver in ALSA, snd-ua101, that reportedly delivers multichannel work. But what's missing is the software control for the direct monitoring mixer. But then, on my FA-101 setup, I don't use direct monitoring from the box ... we have an analog mixer and separate headphone amp for that, the recording interface is just connected via the inserts on the channels (only the send part).

From an audio-cd into Ardour
Hello Community! Just asking your opinion about the best way to do it. That's the situation: I've got this CD from which I want to extract a track (or more) into Ardour in order to modify it (maybe sing on it or other) Do I have to extract it in wave format before? And if so, what's the best way to extract it in the best quality possible? Otherwise, is there a way to put it directly into Ardour? :) -- Ubuntu-Studio-users mailing list Ubuntu-Studio-users@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-studio-users

FLAC is lossless, but there's the need to transfrom data from and to FLAC, so I guess it might be better for a project to chose 'WAV Float 32-bit' directly, even if the original CD WAV is 'Signet 16-bit'. Perhaps the Float 32-bit for the production is better to avoid rounding errors or stuff like this, while the digital data is processed by several apps. *?* -Ralf -- Ubuntu-Studio-users mailing list Ubuntu-Studio-users@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-studio-users

The computer can be the desire by itself or music can be the desire, so hunting and comparing versions, special desktop FX etc. are less relevant. That is of course up to the user, what he or she wants to do with it. For me it has been a hunt for a system that works according to: 1. My hardware needs 2. My software needs What I need is a system that works, flawlessly. Flawlessly means, I don't suffer crashes in the middle of a performance, and I don't hear irregularities caused by the system. Finding that out may be a different experience for people, because of a range of variables. One of them being what hardware is used. Another being what the system is used for. I have yet not worked with -lowlatency for long periods of time, like I have with previous -rt kernels. So far, it does seem as -lowlatency will serve my purposes well. Only one -rt kernel has done that for me so far, but I have not been in this game for very long. And there are more computer users who are experienced office workers, than experienced musicians. Imagine an experience of '20 days a month * 8 hours * several month (years)' using the computer for writing business correspondences or administrating a server and an experience of '4 hours * 52 weekends a year * several years' producing music with the computer. 2 Cents, Ralf -- ailo -- Ubuntu-Studio-users mailing list Ubuntu-Studio-users@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-studio-users
