如何在Android中从均衡器获取更新的音轨？

AudioTrack audioTrack = new AudioTrack(AudioManager.STREAM_MUSIC, sampleRate, channelConfig, audioFormat, bufferSize, mode);

Equalizer equalizer = new Equalizer(0, audioTrack.getAudioSessionId());
equalizer.setEnabled(true);

short minEQLevel = equalizer.getBandLevelRange()[0];
short maxEQLevel = equalizer.getBandLevelRange()[1];
int bands = equalizer.getNumberOfBands();

short[] eqLevels = new short[bands];
for (short i = 0; i < bands; i++) {
    eqLevels[i] = ...; // 设置第i个频段的增益值
    equalizer.setBandLevel(i, eqLevels[i]);
}

float[] audioData = ...; // 音频数据
audioTrack.write(audioData, 0, audioData.length);
