iTunes back door, API, DLL raw sample question

Gang,

I design high end audio asynchronous usb dac hardware. A lot of customers have found that iTunes while nice may not sound as good as actually playing tracks in pro audio tools. The problem with Pro Audio is one track at a time.

One of the reason's why iTunes does not sound as good is that iTunes takes a snap shot of Audio Midi Setup for the device output in question and resamples to that rate and bit size before it goes out. So you may have a 44.1/16 bit track then a 24/96 track and they will both be resampled to the rate specified in the Audio Midi setup. Other problems happen when users forget setting the volume control to 100% and using eq and other sound altering options.

The nice thing about iTunes is there are a bunch of applications for remote access and control as well as the ripping and burning capabilities.

So I had an idea that maybe there was an interface for iTunes were the sample and sample rate info was passed to a DLL or API for processing that we could hijack the sample and out put it to a known device as is without any processing and change the sample rate on the fly. In return to iTunes we would pass the altered sample back as a ZERO so when iTunes passed the sample onto the mixer that it would not interfere or be output as anything.

Anything like that? Anyone interested in helping me out with this?

Thanks
Gordon
