概述经过一番折腾，终于找到了一种第三方库来转换android与iOS录音播放格式不兼容的问题。思路：android／iOS手机录音传给服务器，参数（录音数据+手机端口类型），然后等到服务器广播数据给玩家，判断端口是android，将数据保存为为.amr格式，否则保存为.aac格式。不同手机端口调用相应端口函数。 1、设置端口录音格式: android–>.amr public void record

经过一番折腾，终于找到了一种第三方库来转换androID与iOS录音播放格式不兼容的问题。
思路：androID／iOS手机录音传给服务器，参数（录音数据+手机端口类型），然后等到服务器广播数据给玩家，判断端口是androID，将数据保存为为.amr格式，否则保存为.aac格式。不同手机端口调用相应端口函数。
1、设置端口录音格式:
androID–>.amr

public voID record(){        if (isRecording == true ) return;            recondpath = Environment.getExternalStorageDirectory().getabsolutePath();         recondpath += "/ione1.amr"; //录音格式        file dirs = new file(recondpath);        if (dirs.exists()){           dirs.delete();        }        stopRecorder();                 isRecording = true;         mRecorder = new MediaRecorder();                  //设置音源为Micphone         mRecorder.setAudioSource(MediaRecorder.AudioSource.CAMCORDER);         //设置封装格式        mRecorder.setoutputFormat(MediaRecorder.OutputFormat.AMR_NB);         //设置编码格式         mRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);                 mRecorder. setAudioEnCodingBitRate(8);//设置音频编码录音比特率        mRecorder.setAudioChannels(1);//设置录制的音频通道数        mRecorder.setAudioSamplingRate(8000); //设置音频采样率记录         mRecorder.setoutputfile(recondpath);            try {                mRecorder.prepare();            } catch (IOException e) {                Log.e(TAG,"prepare() Failed");        }        //录音         mRecorder.start();            }    public boolean stopRecorder() {         if( mRecorder == null ) return false;        try{            mRecorder.stop();                mRecorder.reset();            mRecorder.release();                mRecorder = null;           }catch ( IllegalStateException e){            e.printstacktrace();        }        return false;      }

ios–>.aac

-(voID)startAudioRecording{    if(!isRecording)    {        [self init];        isRecording = YES;        NSLog(@"正在录音");        NSMutableDictionary *dicM=[NSMutableDictionary dictionary];        //设置录音格式        [dicM setobject:@(kAudioFormatMPEG4AAC) forKey:AVFormatIDKey];//录音格式        //设置录音采样率，8000是电话采样率，对于一般录音已经够了        [dicM setobject:@(1600) forKey:AVSampleRateKey];        //设置通道,这里采用单声道        [dicM setobject:@(1) forKey:AVNumberOfChannelsKey];        //每个采样点位数,分为8、16、24、32        [dicM setobject:@(8) forKey:AVlinearPCMBitDepthKey];        //录音的质量        [dicM setValue:[NSNumber numberWithInt:AVAudioQualityMin] forKey:AVEncoderAudioQualityKey];        //是否使用浮点数采样        [dicM setobject:@(YES) forKey:AVlinearPCMIsfloatKey];        recorder = [[AVAudioRecorder alloc] initWithURL:recordedfile settings:dicM error:nil];        [[AVAudioSession sharedInstance] setcategory:AVAudioSessioncategoryPlayAndRecord error:nil];        [[AVAudioSession sharedInstance] setActive:YES error:nil];        [self setSoundSession];        [recorder peakPowerForChannel:0];        [recorder preparetoRecord];        [recorder record];    }}

2、接收服务器传来的需要播放的录音数据，根据不同端口录的音保存为数据相同录音格式:
androID–>.amr
ios–>.aac

//服务器传来录音数据，保存在表voiceTab中 //voiceTab[index] = event.datafunction MainScene:startPlayVoice()    if self.isstartRecond  == false then -- 没有在录音        if device.platform == "androID" or device.platform == "ios" then --播放录音             local len = #voiceTab            if len >= 1 then                voicePlay( data )            else                print(" 录音播放完了 ")            end        end    endend

function voicePlay(data)    if device.platform == "androID" then        local function callback(result)            -- print("录音播放完成 " )             ReturnRecordingPlayChange(result)        end        local path = writefileCheckRecond( data.voicebin,data.content )        print("开始播放了 voicePlay ")        local args = { 1,path,callback }        local sigs = "(ILjava/lang/String;I)I"        local luaj = require "cocos.cocos2d.luaj"        local classname = "com/cocos2dx/sample/LuaJavaBrIDge"        local ok,ret  = luaj.callStaticmethod(classname,"sendLuaToJavaAudioRecorPlay",args,sigs)        if not ok then            print("luaj error:",ret)        else            print("The ret is:",ret)        end    elseif device.platform == "ios" then        local path = writefileCheckRecond( data.voicebin,data.content )        print("开始播放了 voicePlay ",path)        local i = iosAudioStartPlay( path )     endend

function writefileCheckRecond( data,platform )    local path = device.writablePath.."netSprite/" --获取本地存储目录    if not io.exists(path) then        lfs.mkdir(path) --目录不存在，创建此目录    end    if platform == "androID" then        path = path.."recond.amr"    elseif platform == "ios" then        path = path.."recond.aac"    else        return;    end    print("写入完成:"..path)    return path;end

3、分析两端口录音互相播放的情况（A端口录音–>B端口播放）
androID–>androID:androID玩家录音为.amr传给服务器，androID玩家接收录音二进制数据保存的也是.amr格式，播放OK。

public voID startPlay(String filePath,int luaFunc){        if( isPlay == true)        {            Log.d("tag","正在播放中");            return;        }        try {            stopPlay();              isPlay = true;            playLuaFun = luaFunc;             mPlayer = MediaPlayer.create(Cocos2dxActivity.getInstance(),Uri.parse(filePath));            mPlayer.start();// 开始播放             mPlayer.setonCompletionListener(new MediaPlayer.OnCompletionListener(){                @OverrIDe                 public voID onCompletion(MediaPlayer m) {                     Log.d("tag","播放完毕");                                           LuaJavaBrIDge.callbackLuaFun("1","ReturnRecordingPlayChange",index++);                       buySuccessJava(1);                    Log.d(TAG,"playLuaFun = " + playLuaFun);                    isPlay = false;                    stopPlay();                }            });        }catch(Exception e){              Log.e(TAG,"prepare() Failed");        }    }

androID–>iOS:androID玩家录音为.amr传给服务器，iOS玩家接收录音二进制数据保存为.amr格式，调用第三方库将格式.amr转.mav格式就播放OK。

-(voID)playAudio{    if(!isPlay)    {        if([player isPlaying])        {            NSLog(@"停止录音播放");            [player pause];        }        else        {            Nsstring *documentsDirectory= [NSHomeDirectory() stringByAppendingPathComponent:@"documents"];            audioRecoderSavePath=[Nsstring stringWithFormat:@"%@/%@",documentsDirectory,@"netSprite/"];            recodername= [Nsstring stringWithFormat:@"%@",@"recond.amr"];            tempRecoderPath=[Nsstring stringWithFormat:@"%@%@",audioRecoderSavePath,recodername];            fm = [NSfileManager defaultManager]; //创建文件管理对象            if([fm fileExistsAtPath:tempRecoderPath] == NO)//判断文件是否存在            {                NSLog(@"文件不存在");                recodername= [Nsstring stringWithFormat:@"%@",@"recond.aac"];                tempRecoderPath=[Nsstring stringWithFormat:@"%@%@",recodername];                isIos = true;                [self startPlayAudio];                return;            }            else            {                isIos = false;                NSLog(@"文件存在");            }            Nsstring *recoderWavname= [Nsstring stringWithFormat:@"%@",@"recond.wav"];            tempWavRecoderPath =[Nsstring stringWithFormat:@"%@%@",recoderWavname];            //第三方库AudioConverter            [AudioConverter convertAmrToWavAtPath:tempRecoderPath wavSavePath:tempWavRecoderPath asynchronize:YES completion:^(BOol success,Nsstring * _Nullable resultPath) {                if (success) {                    NSLog(@"amr转wav成功!");                    _wavfilePath = resultPath;                    [self startPlayAudio];                } else {                   NSLog(@"amr转wav失败!");                }            }];        }    }}
