IM Recorder

SY IM Recorder

• 从SYIMKit拆分出来，提供基础的录音和播放控制功能
• 采用opencore-amr编解码，输出的音频格式为amr
• iOS&Android平台通用

Introduction

• maxRecordFrames：可设置最长录制时间
• minRecordFrames：可设置最短录制时间
• recordFrames：当前录制时间
• mPath：输出路径
• delegate：- (void)syAmrRecorder:(SYIMAmrRecorder *)recorder didUpdateMeters:(float)meters 动态更新音量波动

Enjoy IT!

• 将SYIMAmrCore.framework拖入工程，需添加AudioToolbox.framework、AVFoundation.framework
• 设置build settings->enable bitcode->NO

Example

   - (IBAction)startRecord:(id)sender {
       if (!_amrRecorder) {
        _amrRecorder = [[SYIMAmrRecorder alloc] init];
        _amrRecorder.delegate = self;
       }
    
       if (_amrRecorder.isRecording) {
         [_amrRecorder sy_stopRecord];
       }
    
    //开始录音
    NSString *localAmr = [self generateCacheFilePath:@"amr" fileName:[NSString stringWithFormat:@"local%.f.amr", [[NSDate date] timeIntervalSince1970] * 1000.0]];
    
    //这个路径一定要创建成功后再初始化录音机
    if (localAmr.length > 0) {
        [_amrRecorder sy_startRecordWithPath:localAmr];
    }
}

- (IBAction)stopRecord:(id)sender {
    [_amrRecorder sy_stopRecord];
}

- (IBAction)playRecord:(id)sender {
    if (_amrPlayer) {
        [_amrPlayer stop];
        _amrPlayer = nil;
    }
    
    //这个路径一定要要是存在的，否则播放失败
    if (_amrRecorder.mPath.length > 0) {
        _amrPlayer = [[SYIMAmrPlayer alloc] initWithPath:_amrRecorder.mPath];
        _amrPlayer.delegate = self;
        [_amrPlayer play];
    }
}
