Ode To Sound Blaster: Are Discrete Audio Cards Still Worth the Investment?

MojoKid (1002251) writes "Back in the day (which is a scientific measurement for anyone who used to walk to school during snowstorms, uphill, both ways), integrated audio solutions had trouble earning respect. Many enthusiasts considered a sound card an essential piece to the PC building puzzle. It's been 25 years since the first Sound Blaster card was introduced, a pretty remarkable feat considering the diminished reliance on discrete audio in PCs, in general. These days, the Sound Blaster ZxR is Creative's flagship audio solution for PC power users. It boasts a signal-to-noise (SNR) of 124dB that Creative claims is 89.1 times better than your motherboard's integrated audio solution. It also features a built-in headphone amplifier, beamforming microphone, a multi-core Sound Core3D audio processor, and various proprietary audio technologies. While gaming there is no significant performance impact or benefit when going from onboard audio to the Sound Blaster ZxR. However, the Sound Blaster ZxR produced higher-quality in-game sound effects and it also produces noticeably superior audio in music and movies, provided your speakers can keep up."

    A USB audio interface also lies outside the electrically noisy interior of a PC chassis.

    Strong caution with USB audio. There is a metric buttload of cheap USB adapters, While they technically work, they typically lack analog filtering that gets rid of higher harmonics. If you look at the output on an oscilloscope, instead of a smooth wave, you see the actual steps. Better audio hardware should have filters to smooth this stuff out.

    Another MAJOR thing is inducing noise into the output. This is not just for USB cards, but all audio solutions. You need some pretty good filtering between the digital and analog power domains -- yet another area where cheap sound can skimp. Hey, let's shave $0.05 off by dropping this capacitor and inductor!

    The original article really touches on two separate areas:
    1) Audio processing
    2) Higher quality audio circuitry

    SoundBlaster (and other gaming-oriented cards) typically do both. However, do you really NEED both? The audio processing stuff is supposed to provide an API that games can use to make thing sound more realistic, or offload audio processing from software to hardware, or both. It can typically decode various dolby flavors, and do some other fancy DSP-ish type stuff. Do you really NEED all of that? If so, then maybe a gaming card is for you.

    However, what if you want the best sound possible, the lowest noise possible, and don't really game or use the various audio enhancements? You just want a plain-vanilla sound card, but with the highest quality audio. Where to do? Skip the computer store, but go to your local MUSIC store (not the ones that sell CD's, the ones that sell GUITARS). Those cards skip all of the DSP bells and whistles, but have the best-quality DACs and filtering that you can find. You can find some really good USB solutions that will blow on-board audio out of the water for about $100 or so. Of course, you can go crazy and spend $500 or more if you want. If it is good enough for a music producer to use in a studio (who makes his or her living off of the sound), it is probably good enough for YOUR music and movies.

    Why do you lump Klipsch in with Monster Cables? The founder of Klipsch is renown for debunking many crap claims made by many speaker makers similar to the nonsense claims that Monster makes. Perhaps you mean "No highs. No lows. It's Bose"? K-horns, for example, have always been solid speakers.

    Everybody listen to Harrkev.
    Working as an audio professional, and electrical design hobbyist who has designed many audio circuits, I agree 100% with his statements.

    USB in particular is some noisy shite if it's not done properly and corners are cut, it can also be really great for the price if done right.

    And yes, spending $100 on a used pro audio interface at a music shop can get you the quality of a brand new $500 interface if you know whats what.
