Whats the best approach (read painless) that I could take? Primarily, the application needs to record the webcam video + mic recording on the disk and compress the video using ffmpeg (or something similar).

I'm attempting to use Audio Queue Services for the first time. After reading all the documentation and playing with some sample code, I think I understand the classes pretty well and have implemented my own playback and recording application without any problems. I need to simultaneously record and play from the same buffer, but I'm hav...
I'd like to use Dynamic Time Warping to compare two feature vectors for two audio recordings (of course I'm doing all the necessary preprocessing first). My program should output the similarity between the two audio recordings in percent. For example 100% means that the two recordings are completely identical, and the more different are ...
Consider aurioTouch sample application provided by Apple. I wanted to simulate a lengthy processing of the recorded audio and modified the sample by introducing a delay of 0.1 second in the render callback method: PerformThru. This leads to a distorted audio and static noise being played through iPhone's speaker or headphones. The noise ...
