Default Audio Codec Comparison Table

There has been a new article posted.

Title: Audio Codec Comparison Table
URL: http://www.hardwaresecrets.com/article/520

Here is a snippet:
"Audio codec is a small chip measuring sq. in. (7 mm2) located on the motherboard in charge of the analog audio functions. Knowing the specs of a codec will allow you to compare the audio quality of ..."

Comments on this article are welcome.

Best regards,

Audio codecs matter to audio quality, but nobody pays any attention to them. Hardware Secrets is again leading the way on info that matter to enthusiasts.

Could you guys use a couple of the boards that use high-end and low-end codecs for a sound test? You could make an analog recording from a high-quality source, like a blu-ray or DVD, and post some samples.

Thank you!

We don't even dare to touch this arena! It needs a very talented professional to conduct such tests!

not only professional techs but pro hardware to go along with it (aka $$$$$$)

but as always audio is in the ear of the listener what sounds great to me may sound like garbage to you

thanks for the interesting tidbits

Default Audio Codec Comparison

Indeed, a long overdue, much needed database on PC mother board audio codec chips, great work and idea! On one hand, I agree with Gabriel that providing reviews on the sound quality of PC audio is difficult. On the other, as more people are storing their music on HDDs (serious storage, not MP3s!) and using their PC's to organize and access their music, some side-trips into that area would be useful to PC enthusiasts.

As a former high end audio enthusiast, believe me, you don't want to go there or have HS go there. If they did, you'd have vacuum tube line amplifiers in your PC (not a joke!) and inputs for a turntable. Not that those are bad things, but enthusiast audio can make enthusiast PCs look very, very tame.

If I may suggest an article, I'd love to see one on the implementations of Dolby Digital and DTS sound in PCs. How it is or can be done (source and decoding hardware and software) and support for it by OS's and manufactures. Simply because a codec supports multi-channel sound does not mean it supports the decoding and processing of the Dolby Digital or DTS Surround sound formats.

When it comes to motherboard audio quality my experience is that the audio chip seems to be one of the least important factors.
The supporting electronics design can easily (and all to often do) ruin the chip's potential.
With my last motherboard (Asus A8N-E) I could hear a distinct buzzing noise through the headset when I moved the mouse. That's not supposed to be there at all!

Cheers

It would be nice if you add some info on audio codecs used in laptops...
Plus SigmaTel was pretty popular, not any more...

They are in there. Mine uses RealTek ALC-268, and it's in that list. Granted, the list may not necessarily be inclusive of EVERY model number of codec, but a lot of them are typically just minute changes of other chips and not really worthy of their own model number (despite getting one lol). Furthermore, there is the issue of even being able to find enough specs ON the codecs to merit inclusion in the list heh If they added every codec, it'd be a long table with a whole lot of empty spaces.

Though I will admit, there are a bunch of CMI chips that could very well be added, as CMI's site provides the basic details. Though you likely wouldn't find any found in a computer in the first place, only in aftermarket components.

Thanks for the SigmaTel suggestion. Laptops use the same audio codecs as desktops. If you don't find a specific codec in the tables, please let us know.
