android - Android：通过单声道播放单声道声音

Question

我正在尝试通过单个通道播放单声道声音，我唯一能想到的是将第二个通道交织到字节数组中，更改AudioFormat为立体声然后调用 audioTrack.setStereoVolume(leftVolume, rightVolume);将一个通道的音量设置为零。有没有更简单的方法？

        AudioTrack audioTrack = null;                                   // Get audio track
        try {
            audioTrack = new AudioTrack(AudioManager.STREAM_MUSIC,
                    sampleRate, AudioFormat.CHANNEL_OUT_MONO,
                    AudioFormat.ENCODING_PCM_16BIT, (int)numSamples*2,
                    AudioTrack.MODE_STATIC);
            audioTrack.write(generatedSnd, 0, generatedSnd.length);     // Load the track
            audioTrack.play();                                          // Play the track
        }
        catch (Exception e){ }
