You need to use CFURLRef to point to the file you want to record to. For example:

NSMutableString *fullpathname = @"/var/root/foo.amr";
CFURLRef url;
CFStringRef sref;

sref = CFStringCreateWithCString(nil, 
[fullpathname cStringUsingEncoding:
[NSString defaultCStringEncoding]],
kCFStringEncodingASCII);

url = CFURLCreateWithFileSystemPath(nil, sref, 
kCFURLPOSIXPathStyle, 0);

Start recording by initializing. Once you get this far, it's just a matter of bookkeeping to get your recorder started. Here's the relevant code. Allocate and initiate the recorder instance, activate it and assign it the CFURLRef URL you've created. Then tell it to start. Recording starts instantly.

// Start recording
recorder = [[AVRecorder alloc] init];
[recorder activate:self];
[recorder setFilePath:url];
[recorder start];

Stop the recording with "stop". When you're ready to finish recording, just send a stop message to your recorder and deactivate it. The file has already saved automatically to disk. If you want, you can query the number of bytes written before deactivating by sending a recordedFileSizeInBytes message.

[recorder stop];
[recorder deactivate];
