Wolfson DAC confirmed by Supercurio.

Audio codec:

Wolfson Micro WM1811
http://www.wolfsonmicro.com/products/audio_hubs/WM1811/
100dB SNR Class W Heapdhone amp output, ReTune DSP, 3x digital interface.
Like WM8994 in Galaxy S / Nexus S, except:
1x stereo DAC instead of 2x.
2x 2W Speaker amp instead of 2x 1W
Smaller and probably cheaper, same sound quality expected.

Audio driver configuration & policy implementation based on TinyUCM (/etc/tinyucm.conf)
Probable subset of TinyHAL implementing codec configuration in config files instead of having everything hardcoded in ROM or kernel driver at compile time.

Native sampling rate: 44100 Hz. It means music played will be sent as-is to the DAC instead of being processed by a software up-sampling routine as it is on Galaxy Nexus or other devices with codecs accepting only 48000 Hz.

AWESOME.

As a matter of fact, yes - just a few moments ago Supercurio typed this into his internals report document (which you can watch live):

"Confirmed Voodoo Sound capable "

---------- Post added at 01:12 PM ---------- Previous post was at 01:05 PM ----------

Now Supercurio just wrote this: "USB Audio snd-usb-audio usb class audio driver present. Might work, might not".

This is probably the only reason I might consider s3.

Hi there!

So I'm not the only one happy with the promising audio codec in Galaxy S III ?

Maybe a noob question.. Is the DAC as good as the S1 or better.. Coz This seems to be the only reason to move to the S3..

See above, I quoted Supercurio as saying he expects the same audio performance as the S1 (of course if USB Audio works then we can have even better quality).
