    <p>I got it working for now. I haven't completely fixed it, but I can record without it crashing. I commented out every line having to do with AQRecorderController until it stopped being released, then slowly added them back until I found out where it happens. It looks like the audio session setup code somehow provokes it to release the controller. This is the code that causes it (but no errors are thrown here):</p> <p>From AQRecorderController.mm:</p> <pre><code>-(void)initializeRecordSettingsWithCompression:(bool)compressionEnabled { OSStatus error = AudioSessionInitialize(NULL, NULL, interruptionListener, (__bridge void*)self); if (error) printf("ERROR INITIALIZING AUDIO SESSION! %d\n", (int)error); else { UInt32 category = kAudioSessionCategory_PlayAndRecord; error = AudioSessionSetProperty(kAudioSessionProperty_AudioCategory, sizeof(category), &amp;category); if (error) printf("couldn't set audio category!"); error = AudioSessionAddPropertyListener(kAudioSessionProperty_AudioRouteChange, propListener, (__bridge void*)self); if (error) printf("ERROR ADDING AUDIO SESSION PROP LISTENER! %d\n", (int)error); UInt32 inputAvailable = 0; UInt32 size = sizeof(inputAvailable); // we do not want to allow recording if input is not available error = AudioSessionGetProperty(kAudioSessionProperty_AudioInputAvailable, &amp;size, &amp;inputAvailable); if (error) printf("ERROR GETTING INPUT AVAILABILITY! %d\n", (int)error); // we also need to listen to see if input availability changes error = AudioSessionAddPropertyListener(kAudioSessionProperty_AudioInputAvailable, propListener, (__bridge void*)self); if (error) printf("ERROR ADDING AUDIO SESSION PROP LISTENER! %d\n", (int)error); error = AudioSessionSetActive(true); if (error) printf("AudioSessionSetActive (true) failed"); } } </code></pre> <p>So far, this isn't necessary for the functioning of my app, but I am curious as to why it would cause the AQRecorderController instance to release.</p>

    1. COIs there a reason you're using AQRecorder instead of AVRecorder?

    2. COYes, I need to being able to read the data from the recording buffer (while recording) and upload it to a server while at the same time filling up a local file to save. Its sort of like streaming and as far as I know, AVRecorder does not allow access to the buffers while recording. Of course, it would be great to avoid the C++ and use only AVAudioRecorder, but I have not found that to be a possibility for my project.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
