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."
Onboard sound is finally Good Enough*, and has been Good Enough* for a long time now.

And past this post, no further information from Slashdot ever reached my location.
Yes, a discrete card might have *better* specs (especially analog components, which was a problem on older integrated soundcards), but I haven't felt the need to use a discrete card since my nForce 2 board (Soundstorm).
Besides, it saves me from using Creative's bloatware.
I've got better things to do tonight than die.
For the average user, onboard is just fine.
For a power user (gamer/developer), onboard is probably good enough.
If you're an audio pro and/or you're building a semi/professional audio rig, onboard isn't going to cut it 99% of the time.
FWIW, plug in sound cards are actually more common than a lot of people think, because a lot of people seem to think that if it doesn't go into a PCI slot, it's not a sound card.
The Rocksmith cable, with its built-in discrete audio unit, is a prime example, one that I use almost daily.

No.
Back in the day, integrated audio was the frickin' PC speaker that could only produce one square wave at a time with no volume control whatsoever, apart from software 'hacks'.
And Creative Labs were far from the first ones, learn a bit of history and get off my lawn.

Any money spent on a sound card is better off spent on speakers and a good DAC, which often come together.
High end sound systems and speaker systems these days have digital inputs, thus an onboard DAC. If you're using a digital output on your motherboard to connect to a digital input on the speaker, the onboard sound card has ZERO effect on the quality of the audio. The bits are traveling directly, unmolested from the application generating them to the amplifiers in the speakers.
Now, if you have audiophile-type equipment that uses analog inputs, then YES, the analog sound you feed into those inputs needs to come from a high quality DAC. High end sound cards tend to have good DACs, but you can get the same effect by using an outboard DAC, which has a digital input and analog outputs, and is also AWAY from your PC, so your analog audio is less likely to be affected by interference from the motherboard or power supply.
You can get DACs with USB inputs, but USB adds latency so is best avoided for gaming. For music, go to town with a USB DAC; it won't matter there.
The gist of it is, the most important component is the DAC. The DAC completely determines the quality. Everything else is just hype. :)
...but discrete soundcards, especially external ones, are still alive and well if you record. The noise floor of internal sound cards hasn't gotten that much better (a PC is very noisy RF environment), and if you need mic preamps, quarter inch jacks, optical in, etc, they generally don't fit on a PCI card or laptop.
But for general gaming or home theater use? Nope. Send the audio out over the HDMI out, or SPDIF for DVI/VGA rigs, and let the amp sort it out.

I can't wait to buy a shiny new Sound Blaster ZxR so I can get that noticeably superior audio. It'll be great for my collection of 128 Kbps MP3s!

I give up on debugging. From now on, SIGSEGV is a feature.
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.

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.
There's no need to spend that much. A lot of motherboards have S/PDIF outputs, and with a good coax/TOSLINK DAC (like the ~$40 FiiO D3), pristine noise-free stereo sound is both easier and cheaper than buying an expensive sound card.
