SWITCH_FILE_FLAG_READ: I'm not sure what this does. It's somewhere else in the code.
It specifies that the file is being opened for reading (SWITCH_FILE_FLAG_READ) rather than writing (SWITCH_FILE_FLAG_WRITE). They actually wrap similar values in the APR library. -Steve On 25 February 2011 15:09, MatzeMuc86 <matzemuc86@gmail.com> wrote:

My idea: A conference room for regular sip clients but also special user clients which can receive stereo. Stereo is needed as those clients will get a special HRTF sound: different people are placed on different 3D positions in the room and you can hear them. This is NOT regular stereo sound but real 3D sound. Why is this better: Mixing all together to one mono channel, it is very difficult to distinguish between different people. Interesting links: http://en.wikipedia.org/wiki/Head-related_transfer_function and http://en.wikipedia.org/wiki/Cocktail_party_effect. There have been several tests (and there is literature as well) that proofs that it is much easier to follow conversations which use 3D sound like HRTF. And I want to do this not by some proprietary software like it is done by with Mumble by J. Feldmayer but with SIP to be able to connect also regular SIP clients (and regular phones or whatever I want).

1. This also depends on when the flags is set to SWITCH_FILE_FLAG_READ, right?
BTW, I am just curious what kind of application will you be making that requires a stereo. Do you care to tell us? Perhaps, once the readers understand what your application is, there may be some interests.
