- 在文档目录下保存wav录音
-
下面的代码用来保存一个.wav格式的录音文件,然后加到Email中,但是在Email中没有成功邮出。可能是在录音中出了问题,请大家帮忙看一下。NSArray *pathComponents = [NSArray arrayWithObjects: [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject], @"MyAudioMemo.wav", nil]; NSURL *outputFileURL = [NSURL fileURLWithPathComponents:pathComponents]; // Setup audio session AVAudioSession *session = [AVAudioSession sharedInstance]; [session setCategory:AVAudioSessionCategoryRecord error:nil]; // Define the recorder setting recordSetting = [[NSMutableDictionary alloc] init]; [recordSetting setValue:[NSNumber numberWithInt:kAudioFormatLinearPCM] forKey:AVFormatIDKey]; [recordSetting setValue:[NSNumber numberWithFloat:44100.0] forKey:AVSampleRateKey]; [recordSetting setValue:[NSNumber numberWithInt: 2] forKey:AVNumberOfChannelsKey]; [recordSetting setValue:[NSNumber numberWithInt: 16] forKey:AVLinearPCMBitDepthKey]; [recordSetting setValue:[NSNumber numberWithBool: NO] forKey:AVLinearPCMIsBigEndianKey]; [recordSetting setValue:[NSNumber numberWithBool: NO] forKey:AVLinearPCMIsFloatKey]; [recordSetting setValue:[NSNumber numberWithInt: AVAudioQualityHigh] forKey:AVEncoderAudioQualityKey]; // Initiate and prepare the recorder audioRecorder = [[AVAudioRecorder alloc] initWithURL:outputFileURL settings:recordSetting error:NULL]; audioRecorder.delegate = self; audioRecorder.meteringEnabled = YES; [audioRecorder prepareToRecord];
