媒体播放器的混响不工作 [英] mediaplayer reverb is not working

问题描述

我想申请混响效果进行输出组合创造了混响（音频会话0），以媒体播放器，我用这个code

 公共无效REVERB1（视图v）{
    presetReverb mReverb =新的presetReverb（0,0）; //＆LT;＆LT;＆LT;＆LT;＆LT;＆LT;＆LT;＆LT;＆LT;＆LT;＆LT;＆LT;＆LT;
    mReverb.set preSET（presetReverb preSET_LARGEROOM）;
    mReverb.setEnabled（真）;
    mp1.attachAuxEffect（mReverb.getId（））;
    mp1.setAuxEffectSendLevel（1.0F）;}
 

然而，当我开始播放歌曲，并应用没有任何反应的效果，歌曲继续，不应用混响效果。我在清单还添加了这个$​​ P $ pmission ＆LT;使用许可权的android：NAME =android.permission.MODIFY_AUDIO_SETTINGS/＆GT;
还是同样的结果，我是不是做错了什么？
 我也试过 presetReverb mReverb =新的presetReverb（0，
mp1.getAudioSessionId（））; 但是还是一样的结果。

任何帮助将AP preciated

解决方案

  presetReverb mReverb =新的presetReverb（0，mp1.getAudioSessionId（））;
 

此构造函数有两个参数，第一个是优先考虑，另外一个是音频会话ID。如果妳想要混响超过乌尔保持优先级为1，并使用全球audiosessionId。

  presetReverb mReverb =新的presetReverb（1,0）;
mReverb.set preSET（presetReverb preSET_LARGEROOM）;
mReverb.setEnabled（真）;
mp1.attachAuxEffect（mReverb.getId（））;
mp1.setAuxEffectSendLevel（1.0F）;
 

一件事要注意的是，这个混响效果是不是在一些设备支持...... becaz他们有有限的均衡器波段。我没有完美的资源来确认一些设备我的状态，但我测试的一些设备和放大器一样的;它的正常工作一段而不是一些做工精细

I am trying to apply reverb effect to mediaplayer by creating a reverb on the output mix (audio session "0" ) , and I use this code

    public void reverb1(View v){
    PresetReverb mReverb = new PresetReverb(0,0);//<<<<<<<<<<<<<
    mReverb.setPreset(PresetReverb.PRESET_LARGEROOM);
    mReverb.setEnabled(true);
    mp1.attachAuxEffect(mReverb.getId());
    mp1.setAuxEffectSendLevel(1.0f);

}

However when I start the song and apply the effect nothing happens, song continues and reverb effect is not applied. I also added this premission in manifest <uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS"/> Still same results, am i doing something wrong? I also tried PresetReverb mReverb = new PresetReverb(0, mp1.getAudioSessionId()); But still same results.

any help will be appreciated

解决方案

PresetReverb mReverb = new PresetReverb(0, mp1.getAudioSessionId());

This constructor takes two arguments, first is priority and another one is the audio session id. If u want to reverb than keep ur priority 1 and use global audiosessionId.

PresetReverb mReverb = new PresetReverb(1, 0);
mReverb.setPreset(PresetReverb.PRESET_LARGEROOM);
mReverb.setEnabled(true);
mp1.attachAuxEffect(mReverb.getId());
mp1.setAuxEffectSendLevel(1.0f);

one more thing to note is that this reverb effects are not supported in some of the devices ...becaz they are having limited equalizer bands. I don't have perfect resources to confirm my state about some devices , but i tested the same on some devices & it's working fine for some and not working fine for some
