Cross-Platform sound recorder

Hello, The project is a cross-platform sound recorder, with the following needs: - Record what is currently played, like in stereo mix (not from the mic or smt.) - Record in Windows, Mac Os, Linux and etc. - Has two buttons: Start and stop recording - Auto-detect sound card settings, and abstract the sound card (like creating a virtual sound card) - Disable the change in sound level of the system during recording (lock the mixer...) - Record .raw files: Number of audio channels:1 Sampling rate:22050 Hz Data: Signed 16bit little endian - Should be written in Qt or plain C++ Note: i-Sound Recorder for Windows 7 is a good example on making the recording independent from the sound card. [login to view URL] The sound card emulation/simulation is critical, because it should work on all systems, and the output data should not change whether a headphone is inserted or not. (This is what seperates i-Sound from other recorders) Details will be given to the winning bid. Don't hesitate to ask questions.
