snow leopard singing

the USB audio interface is now singing flawlessly with MAC OS X 10.6.5

it can stream 24/192k audio files with ease.

but remember, if you are using iTunes to play your music, it won't stream at its native sample rate, it depends on the rate that is set in you audio midi setup.

if you want to have your audio files playing at its sampling rate, you need a player software that could "switch" sampling frequency in Mac OS X.

some example,

Pure Music,
it's non free but demo version is available.
it is basically an add on to iTunes so audio files will be played at its native rate.

it's free and formerly called "AyreWave"
again, it can play your files at its native rate but it still contains some bug .......

i'm using Pure Music at the moment.

got it, finally......

after more than a year of development, my USB audio class 2.0 interface finished.

it's complying the USB Audio Class 2.0 standard, will have native support in Mac OS X 10.6 (or later) and Linux (with the lastest ALSA). a custom (ASIO) driver for Microsoft Windows (XP and Windows 7) is also available. :-)

apart from standard S/PDIF (and AES/EBU) output, it also equipped with an I2S output.
