New page on USB transfer of audio
 

Hi,

Just to let people know about a page I've just put onto my website at

http://www.audiomisc.co.uk/Linux/Sou...ForChange.html

This looks at how uniformly timed audio data replay is when using USB. It
uses a new measurement method I devised as I wasn't happy that the common
methods people have been using are ideal for this. The results compare a
direct USB connection and using a Halide Design 'Bridge' into a DACMagic.

All being well, I'll also put up a page giving the details of how the
measurement method works when I get a chance. [1] Although people with a
background in comms may be able to guess this from my choice of 'IQ-Test'
for the approach. I chose this name as it is also a joke with the name of
the 'J-Test'. ;-)

Slainte,

Jim

[1] This involves some 'hard sums', etc, so I decided it made sense to
seperate explaining the method from the results.

I've now added another page with the 'hard sums'[1] along with an
explanation of how the IQ-Test works. You can find this at

http://www.audiomisc.co.uk/Linux/Sound3/TheIQTest.html

It also gives some details of the settings, etc, I used to get the results
for the Halide Design Bridge.

In due course I'll also make the software available (inc source code) in
case anyone else wants to experiment with it.

Slainte,

Jim
