[Feel free to point me to another forum (perhaps at a different site), but since I have to *get* the AC3 before I can use tools discussed here, I found no better place to start.]
My goal is to write a small application that can capture a digital audio stream (AC3 or PCM) from an Edirol UA-1D (http://www.edirol.com/products/info/ua1d.html) USB capture device.
I've never written capture software before, although I know enough about how things work that some general pointers in the right direction would probably suffice. (Any pointers to Open Source software which does something similar would be welcome.)
What I want to do is, given an input to the device of AC3, record the AC3 stream (or perhaps it will be an SPDIF stream with AC3 embedded in it) to a file. Then I can go about using some other tools for extraction and playback. (The extraction part is assuming I'm not getting the raw AC3 with whatever capture method I come up with.)
So, hopefully that's enough information for someone to point me to some API documentation or other source of information. (In trying to research this topic it didn't seem like OSS would be correct because it seems to assume an analog input that is sampled.)
Anyway, there you go...
