rtcp/rtp语音

iPhone下udp，rtcp/rtp的及时语音通话。

占坑，代码需要整理...

#import <Foundation/Foundation.h>
#import <AudioToolbox/AudioToolbox.h>

#define kRecordBuffers	9

/*
采集语音
 */
@interface AudioRecord : NSObject {
    IBOutlet UILabel* _averagePower;
    IBOutlet UILabel* _peakPower;
    
    AudioQueueRef mQueue;
    AudioQueueBufferRef			mBuffers[kRecordBuffers];
    AudioStreamBasicDescription mFormat;
    AudioQueueLevelMeterState *_chan_lvls;
    NSArray *_channelNumbers;
    
    BOOL recording;
}
-(void)setChannelNumbers:(NSArray *)v;
-(void)initAudioSession;//初始化
- (IBAction)startstop;//采集或停止

-(int)getRecordByteSize;//已采集的字节数
-(int)getRecordPacketSize;//已采集的字节包数

-(void)setRecording:(BOOL)bl;//是否继续采集
