推荐答案

尝试使用 AVAudioPlayer 和 AVAudioRecorder 类进行音频录制和播放.首先您必须使用 AVAudio 会话类建立音频会话

try using AVAudioPlayer and AVAudioRecorder classes for audio recording and playback.Initially you have to establish an audio session using AVAudio session class

AVAudioSession *audioS =[AVAudioSession sharedInstance];
[audioS setCategory:AVAudioSessionCategoryPlayAndRecord error:&error];
[audioS setActive:YES error:&error];

NSURL *url = [NSURL fileURLWithPath:@"/dev/null"];

NSDictionary *settings = [NSDictionary dictionaryWithObjectsAndKeys:[NSNumber numberWithFloat: 44100.0],AVSampleRateKey,
[NSNumber numberWithInt: kAudioFormatAppleLossless], AVFormatIDKey,
[NSNumber numberWithInt: 2],AVNumberOfChannelsKey,[NSNumber numberWithInt: AVAudioQualityMax],         AVEncoderAudioQualityKey,
                          nil];

然后初始化记录器和播放器类...希望这有帮助

and then initialize the recorder and player classes...Hope this helps
