Getting High-Quality Audio From a PC 295

Posted by kdawson from the sounds-like dept.
audiophile writes "Just because it's a PC doesn't mean it can't output good-sounding audio. In the same vein as specialty A/V products, you can find PC-based A/V systems with extensive audio processing and step-up performance specifications, including Signal-to-Noise ratio, which can make a significant difference when using the analog outputs.

      "Isn't that how it usually goes?"

      Well, like most things...hardly anyone gets all the high end stuff all together, right off to bat!!

      My stereo? I've been building it since I was about 12 years old. Right now it is all in storage as that I'm still a bit 'nomadic' since Katrina, but, I've built it starting with money I made back then babysitting, and doing yard work. Started with a Zenith stereo...el cheapo. I saved, and bought a Marantz reciever...then, my Dad found a good closeout sale on some pretty good sized Fisher speakers...I saved and couple years later, bought a pretty decent pioneer turntable. From there an Xmas present of a pretty decent at the time cassette deck (the sharp one which was one of the first to be able to skip songs, etc)...from there over the years, CD players when they came out in college....found a pair of 15 yr old Klipsch Cornwall speakers available just as I got a tax refund...later, Marantz gave out...found a Carver pre-amp with pro-logic, and their 4 channel cathedral amp...Klipsch got stolen...deal with insurance allowed me to spend $1800 and get Klipsch K-Horns (the same speakers I'd been drooling over since 12 yrs old). I've since gone to using the Decware tube amplifier...etc.

      I run this system off a media box I've built, with my tunes ripped to FLAC...and I love the sound. But, while the system I have now (other equipment omitted), is in the multi-thousands of dollars, I didn't buy it all at once. Unless you are born into money, do like the rest of the world, and work hard and save and build slowly. Once you get to the point when older that your starting to pull down some serious bucks...well, you can splurge then...but, if you've been building all along, you'll find you have MOST of what you want by then.

      I'm at the point now, of looking into higher end sound cards, I'm figuring that is probably the weak link in what I have now...when I buy a home, I'm gonna look into getting another set of some type Klipsch heritage speakers for the surround ones...as small as Heresy's, or maybe even LaScalla if the room is big enough.

      See? you never have to quit dreaming and building your system...

        When you move into your new home, don't forget the Ultra Super Mega Hi-Definition Monster Cables, just $199.99/linear foot! The increased resonances fidelities and resolutions will be well worth it. Also, it's much better to be safe and completely isolate your audio system from the power grid by running it entirely off of car batteries (I buy the batteries that Nascar uses since they're the highest quality). It may seem expensive but it's well worth it. I've spent over $150k on my audio system so far and I can *hear* the difference. Every time I buy a new component that costs 10x what the old component cost, it definitely sounds better.

          Monster cables suck. There are good cables and bad cables, but you'll often find the good ones cost less than the bad ones. For example, I know audio engineers (designers of equipment costing 10's of thousands) who use CAT-5 for interconnects and mains power cable for speakers. Why? Because it sounds good, it's easy to get hold of, and it's cheap.

          Whilst I understand that the world of high end audio has more than it's fair share of snake oil salesman selling overpriced crap (like the wooden volume knob) I get really sick of sarcastic comments from know-it-alls whenever anyone mentions having a decent audio setup.

          To be perfectly honest, except in cars that are really well-insulated from the outside world, most of the quality on a CD or a decently-encoded digital file is going to be lost.

          If your threshold for music listening is around 95 dB (which is only safe for 4 hrs/day anyway), and the road noise in the car at highway speeds is 60-75dB (the latter is allegedly the figure for my car as-built, a VW GTI, from an auto magazine) then you only have at most 35dB between the noise floor and max while driving.

          That's already worse than most cassette tapes, particularly decent ones with Dolby NR. (I don't think they even sell the metal tapes anymore, but my recollection is that they were 30+ dB right out of the package without any noise reduction at all.)

          In a way, it explains why so much popular music and FM radio is compressed: there's no reason to offer more than 40dB of dynamic range, because (assuming your listeners don't turn it up to unsafe/painful volumes) they'll never hear the quiet parts because of all the noise in the listening environment.

          Frankly, I think the biggest single thing you can do, in terms of improving the sound system in your car, is to install a lot of Dynamat or other sound-insulating material. Most car stereos, even the factory ones, have far more resolution than you'll hear except when sitting in a parking lot. If you can drop that noise floor even 5dB, you'll get that much more "loudness" out of your stereo without upping the volume to dangerous levels.

      While your ability to hear deteriorates with age, your ability to listen tends to increase, and you have more data in your brain for comparison, to know when something isn't quite right. When you're 18 and volume and bass is what counts, you might not notice that the high hat sounds like broken glass and the xylophone appears to move between the speakers depending on the note played. You might even think it's supposed to be that way. When you're older, you might be more critical and less accepting of flaws, even if you can't hear all the flaws.

      Anyhow, I think the OP should have mentioned that this article is about audio for *AV*, and not pure audio. There's a vast difference between that and pure audio. While a movie can sound awesome with a bunch of small satellites and a sub, that will never do for, say, a recording of a symphony orchestra, where you know the timpani and double bass players aren't sitting on top of each other. Yes, bass at high volume (like in a movie) isn't very easily positioned, but at lower volumes, it's very noticeable. Likewise, when listening to a church organ, you can hear where the different pipes are. They don't move around, depending on the quality and frequency range of 7 different speakers. And when you listen to an AV system, you never play with the volume way down -- you're really only interested in accuracy at high volumes, quite unlike with high end audio.

    Audio should not be done inside a PC. Well, not the analog portion, anyway. Ever looked at anything inside a PC with an oscilloscope? The noise environment is awful. You should not be trying to clean up the power the PC provides to the point you can use it for analog work; it's just not worth it. Especially when you'll just get hit by all the radiated EMI inside the case.

    The solution? Simple -- ship the data out digitally and do the analog work elsewhere. Fortunately this has become very easy, with S/PDIF and the availability of good amplifiers with digital inputs. Amplifier power supplies are designed to be clean, and there aren't high current noisy loads on them -- they're designed for analog work. I have a fully digital amplifier from Panasonic that I'm very happy with. (Fully digital meaning all the way to the output FETs -- it does a delta-sigma pulse density modulation directly on the output signal, which turns out to be a very low noise, inexpensive way to get high quality output.)

Ship the audio outside the case in digital form to something that's designed to handle the analog half. And besides, most PC users don't have to do the A/D half *ever* -- they get their audio in digital form, so the goal should be to keep it that way until it's as close to the speakers as possible and then only do the conversion once.

    - Pay attention to available connections
    - Consider the effects of bass management
    - Analog offers the highest performance soundtracks
    - Digital connections generally work best set to Dolby Digital Live or DTS Connect
    - Choose High Quality ripping settings


    And, look at this pearl:

    Lossless CODECs preserve all of the detail of the original media. For example, the WMA lossless CODEC is recommended for storing music which will be played back on a hi-fidelity home audio system.

      Why would anyone even think [that a PC can't output good-sounding audio]?

      A lot of PCs have historically used really, really cheap components in their audio systems, that introduce noticeable distortion and have crappy signal-to-noise ratios. In some applications, that crappy S/N ratio may just not be good enough. This is not rocket science, and it's certainly not spending $1200 on a power cable. It's just common sense.

      And I preemptively apologize for the snappish tone of this, but whenever anyone mentions anything that suggests one might want to buy an audio component higher quality than what you can get at RadioShack, they're immediately hit with "Have you seen the expensive cables audiophiles buy LOL audiophiles are stupid ha ha." Yeah, ha ha, funny funny. There's been "snake oil" in high-end audio for decades. There are also great price-to-performance values, and systems that--as shocking as it may be--really do have measurably better sound.

        99% of music is indistinguishable from CD in 256kbps AAC (I don't have many 256k MP3s).

        But some waveforms are just too hard to compress. In particular, harpsichords, solo classical string instruments, and solo electric guitar (through some filters) start to sound strange even at 256k.

        A good but not foolproof way to figure out what is going to be troublesome to compress is to compress it losslessly using FLAC or ALAC and look at the resulting mean bitrate. Most stuff that compresses to between 400-600kbps, which is most music, will be fine at 256k. Some of my music, though, exceeds 900kbps lossless, and I even have a couple tracks over 1000kbps (where uncompressed PCM = 1411kbps). In all cases this stuff sounds like crap compressed to 256k. The harpsichords, in particular, sound harsh and flat, since the exceedingly complex waveform they make just can't all fit.

        For me, it doesn't matter in the end, since I rip everything losslessly and then compress it for the car or the iPod where sound quality really doesn't matter anyway. But some people may not want to use hundreds of GBs of disk space or may have more music. For them, strategic ripping is in order.

    [For example, after reading buyers reviews and critics, I settled on the Terratec phase 28. http://audioen.terratec.net/modules.php?op=modload &name=News&file=article&sid=7 [terratec.net] ]

    The only thing to be careful about with such a setup is to not shut down your PC (reset/reboot is fine) while your amp is still on.

    Investing in a high grade sound card is the same as investing in a good amplifier or speakers : you are likely to use it for a long time (unlike a graphics card for example).

    Since a lot of PC audio equipment is geared towards gamers and people listening to low quality MP3's, it is easy to get loud, deep, multi-channel audio. The hard part is getting clear crisp sound. The one downfall I have found with HTPC's is that I have a much harder time hearing the dialog clearly for some movies then I would

(Of course, you can --not "will" -- get better sound if you spend more.)

      I have a question - why are you resampling to 24/192? If your source is 16/44 you're not going to improve anything by resampling...and that ratio is potentially going to lead to degredation (192 is not an integer multiple of 44).

    not to be a downer, but the #1 thing is to protect your ears.

    * keep the volume down, whether speakers or headphones
    * be careful of occupational noise...use foam earplugs or over-the-ear mufflers, make your employer pay for them and make sure your co-workers know about hearing damage too
    * stay away from loud concerts, parties, dance halls
    * get your hearing checked every couple of years by an audiologist
    * don't overdo the drugs, booze, or caffiene
    * if you are exposed to even moderately high sound levels, let your ears rest for a couple weeks before exposing them again. do not *ever* go to two rock concerts in the same weekend
    * at the first sign of infection or fluid buildup, see a doctor
    * hearing loss can be instantaneous and permanent, don't risk it

    All the megabits and SNR in the world won't help if your nerve cells and eardrums are making little buzzes, whines, and clicking noises. You can buy a better sound card or nicer speakers but you cannot replace damaged hearing: PROTECT IT
