avaudiorecorder

I'm hoping someone out there can back me up on this... I've been working on an application that allows the end user to record a small audio file for later playback and am in the process of testing for memory leaks. I continue to very consistently run into a memory leak when the AVAudioRecorder's "stop" method attempts to close the audio file to which it's been recording. This really seems to be a leak in the framework itself, but if I'm being a bonehead you can tell me. To illustrate, I've worked up a stripped down test app that does nothing but start/stop a recording w/ the press of a button.

My app includes the ability for the user to record a brief message; I'd like to trim off any silence (or, to be more precise, any audio whose volume falls below a given threshold) from the beginning and end of the recording. I'm recording the audio with an AVAudioRecorder, and saving it to an .aif file. I've seen some mention elsewhere of methods by which I could have it wait to start recording until the audio level reaches a threshold; that'd get me halfway there, but won't help with trimming silence off the end. If there's a simple way to do this, I'll be eternally grateful! Thanks. This

In my application for recording and playing audio using AVAudioRecorder and AVAudioPlayer I came across a scenario in the case of incoming phone call.While the recording is in progress and if the phone call comes,the audio recorded after the phone call is only recorded.I want the recording recorded after the phone call to be the continuation of the audio recorded before the phone call. I track the interruption occuring in audio recorder using the AVAudioRecorderDelegate methods (void)audioRecorderBeginInterruption:(AVAudioRecorder *)avRecorder and (void)audioRecorderEndInterruption:
