Solid-State Mini-ITX Linux Recording Studio HOWTO

An anonymous reader submits "LinuxDevices.com has posted a project howto on building a dedicated music recording and editing computer that uses a CompactFlash card instead of a hard drive, to eliminate hard disk chatter. It uses the latest release from the Agnula (GNU/Linux Audio) project, and the newest Epia MII-12000 mini-ITX board from VIA. The method described in the article applies to embedding most any Knoppix-based Live CD onto CompactFlash boot media."

Run monitor and keyboard cables the 15 feet, and you have a system that can be as loud as it wants to be without getting anywhere near your recording.

      WRT bit depth, I strongly agree, mainly to avoid having to spend so much effort getting levels set correctly prior to recording. The sampling rate, though, is a little more complicated.

      Any digital data processing that would generate higher frequency data than can be adequately captured in a 44.1 kHz sample rate are also, by definition, outside the range of human hearing. Doing significant pitch shifting might be an exception because it is mucking with the effective sampling rate, but for most audio processing, one would expect no audible difference. Even for pitch shifting, though, you should have to make a pretty big shift to hear significant aliasing, assuming a decent pitch shift algorithm is used.

      However, there -is- a very definite benefit to sampling at 96 kHz in terms of filter loss at capture time. The subtle differences often become much more evident for more heavily-processed tracks.

      In theory, an optimally-designed audio card will show no audible difference between audio sampled at the two bitrates. However, in reality, this is not the case. The reason for this is inherent to the design of an ADC.

      In an ADC circuit, prior to the actual sampling hardware, the analog side of the circuit contains an anti-aliasing filter. In an ideal world, this filter would be a very sharp low pass filter that passes everything from 0 Hz up to precisely half the sampling rate (the Nyquist point). A good example of why this is necessary can be seen by watching a wheel on TV. As the frame rate is exceeded, the wheel reverses. In audio sampling, this results in bogus additional waveforms within the human hearing range. Thus, to avoid the problem, everything above the Nyquist point gets thrown away by these analog filter circuits.

      In the real world, however, analog filters are fundamentally flawed. You can get a fairly steep slope, but in general, the steeper the slope, the more expensive the hardware. And even with a steep slope, there may be portions of the frequency range where there are boosts and dips prior to the cut-off. If you are sampling at 48 kHz, a cheap filter might start rolling off at 14 kHz, well within the hearing range of somebody with good ears. If you are sampling at 96 kHz, that roll-off might start at 36 kHz, well outside the hearing range of humans.

      Thus, the ideal way to handle this is to sample at 96 kHz (or 88.2 kHz), then downsample in software. This way, you get the more accurate high frequency response afforded by the higher frequency filter cut-off without doubling your storage by storing unnecessary interim samples.

      We aren't talking about free-floating obejcts here. The arm on the hard drive is going to bend only as much as the material the arm is made-of is going to allow. Obviously, as G-forces increase, so to does the tendency of any material to bend or break. However, you grossly underestimate the strength of 2.5" hard drive arms. Not only are they made from strong materials, but they are quite short in notebook hard drives.

      Under most circumstances, the place that forces get great enough to damage a hard drive is only upon direct impact. The acceleration is rarely strong enough to cause the hard drive arm to bend down to meet the platters. If you take away that final impact-shock, the acceleration would have to be very, very significant. Falling 10 feet would not do it. Getting shot out of a cannon might. You, of course, have to use very good shock-mounts, such as very long springs with a linearly increasing resistance to stretching/compressing. They will linearly accelerate the hard drive, allowing the unit to exist inside something recieving very serious forces, while the hard drive will only feel the forces linearly increase. In other words, in the case of 10Gs, it would only feel perhaps a 1G increase in forces every fraction of a second as it accelerates. You can keep a egg from breaking using such shock-mounts, so hard drives don't pose much of a special problem.

      In addition, you should consider the direction that impacts are most likely when you are mounting the drive. If you expect most impacts to be a straight up/down drop, you can mount the drive vertically, and even without shock-mounting, it would lead to the arm going torwards the center or the edge of the drive, but not impacting the platters. In reality, since nothing is ever perfectly straight, it would impact the platter, but only with a fraction of the force you'd get otherwise, so you still need shock-mounts.

The EMU chips and the CS46xx (like those in the Santa Cruz) are probably some of the best choices for audio on Linux, even if they are considered to be "consumer-grade". There is no doubt in my mind that some of M-Audio's hardware has a better S/N ratio and THD than that of the Santa Cruz, but it's not substantial enough to warrant the shear lack of features that you'll get with using the Envy chips on Linux.

    I've also noticed that Turtle Beach now makes a card called the "Catalina", which looks like standard Envy 24 HT-S fare. How disappointing. I've never been a Creative Labs fan, but they appear to make one of the only new chipsets anymore with halfway decent Linux support. Audigy 2 is technically inferior to the M-Audio Delta hardware (in terms of recording capabilities, like true 24/96 support), but it's superior in a sense that its hardware actually works very well. You can't say that for any of the Envy 24 lineup, especially the low-end Envy 24 HT models.

    Man... I'm sorely disappointed at the state of PC Audio. It's actually *regressed* in the past few years. Companies think that it's enough to simply add a few extra speaker channels and tout 96 KHz SPDIF output, but it ISN'T enough. Look at this comparison:

    http://turtlebeach.com/site/products/soundcards/ ca talina/comparisons.asp

    Sure, the M-Audio Delta hardware is more advanced than Catalina (especially with the more sophisticated Envy 24 chip), but the fact that it has a million XLR jacks and 24/96KHz doesn't change the fact that the Envy DSPs are near-useless junk on Linux. Besides... Most home users are going to introduce more noise anyway, through their cheapo mics and mixing boards, than any of these soundcards produce, and then they're going to master CDs at 44 KHz. Anyone else that needs to do serious audio work, beyond what I mentioned, probably won't use Linux anyway.

    I'll probably stick with my Santa Cruz until someone starts making decent DSPs (with balls) again. UNCreative is probably the only future option that even comes close.

    I am using a 340MB MicroDrive that I got cheaply from a listing pointed to by slickdeals. I am using it with a IDE->CF adapter that I got off eBay. It works like a regular drive, but spins up very quickly (loads faster than laptop drives) and spins down after 5 seconds of usage, regardless of the power saving setting. So, I don't have to worry about wear leveling. Noise only happens when the disk is being used when some log is written to. No DMA (which can be a little troublesome to avoid due to some kernel distributions setting the use-DMA-by-default-for-IDE, but it's as fast as a hard disk and better for the purpose as a fixed storage device.

    (Everything under / except the volatile stuff in /home, /etc, and /var is in a 512MB tmpfs partition, which gets created by an tar -xzf from a no-emulation CD-ROM boot. The machine is a VIA EPIA 800 with 1.0 GB memory.)

  70. those are inductors by Anonymous Coward · · Score: 2, Informative

    Capacitors are silent. Inductors store energy magnetically and thus create magnetic fields. The magnetic fields cause the inductor windings to shift slightly. In a switching power supply the windings are charged and discharged over and over. This makes a tone. As the load on the power supply changes the frequency can change. Thus you get the up and down slide chirps.

  71. Studio? I think they do not get the point... by NeedleSurfer · · Score: 4, Insightful

    I am a professionnal audio technician (in Quebec you cannot say engineer...), I have been since the past 7 years. I've worked in post-prod, I've been a technical supervisor and teacher for a sound design school, I've been working in AV for the past 4 years and I am an audio consultant for musicians and project studios and home studios. I have been formely trained in audio and have been trained by my present employer in broadcast video. I have helped conceived and built 2 commercial grade studios (heh, you never do those alone...). All of that crap to say: I know my trade and I have the experience to assess of what follows;

    Studio owner, studio technicians, studio operators, studio people, they don't want a studio in a box, mixing with a mouse sucks anyway. There are of course control surfaces that exist to aleviate this problem but, as any pro audio person will tell you, you do not want only one source of processing in your studio you want as many colors as you whish, as many mics model as you can so as to capture your sound and enhance or atenuate certain aspects of it. You want knobs and faders to access as rapidly as possible what you need, you want to control your fades so they fit right in the mix, you do not want to draw them. And I say that as a digital audio and hybrid studio oriented audio tech. As much of a (not) novelty this thing is it only remains a curiosity, plus I doubt many control surfaces actually work on Linux, not many AD/DAs must be either. And to be honest, appart from the fact that mini-ITX machines are usually pretty silent, what's the purpose of small here? The smaller the box the more interferences you will have in your signal, don't forget that part of a digital audio circuit is actually analog and subject to all the garbage found inside a computer box. Even if you use external boxes for your connectors you won't be protected against the added heavy jitter and granulation noise brought by those interferences. Of course you could use a very well shielded card, but will a shielded card fit inside those tiny boxes?

    And how much more of your money are you willing to invest in harware and time to not pay for your OS...

    Anyways, you get the idea. Long live audio on Linux, I am really looking forward to seeing good solutions appearing on this system but this isn't one of them. I see Linux in audio as an embeded OS for external processors, I see it at the hearth of studio-in-a-box (not the computer form factor but the mixing consolle/recorder form factor) machines, various crazy and imaginative audio appliances but not as a general purpose OS used for audio.
