在录制音频时，可以使用AudioRecord类来指定音频源、采样率、通道数量等。要防止音频裁剪，可以先通过AudioRecord.getMinBufferSize()方法获取录制缓冲区的最小大小，并将其用作设备缓冲区大小。同时，还需将采样率和通道数量设置为适当的值，以确保录制过程中不会出现波峰裁剪。

以下是一个示例代码，可以记录背景音乐并检测是否存在波峰削减：

private static final int RECORDER_SAMPLERATE = 44100;
private static final int RECORDER_CHANNELS = AudioFormat.CHANNEL_IN_MONO;
private static final int RECORDER_AUDIO_ENCODING = AudioFormat.ENCODING_PCM_16BIT;
private int bufferSize = AudioRecord.getMinBufferSize(RECORDER_SAMPLERATE, RECORDER_CHANNELS, RECORDER_AUDIO_ENCODING);

private AudioRecord audioRecord;
private boolean isRecording = false;

private short[] audioData;

private void startRecording() {
    audioRecord = new AudioRecord(MediaRecorder.AudioSource.MIC, RECORDER_SAMPLERATE, RECORDER_CHANNELS, RECORDER_AUDIO_ENCODING, bufferSize);

    isRecording = true;

    audioData = new short[bufferSize/2]; 

    audioRecord.startRecording();

    while (isRecording) {
        audioRecord.read(audioData, 0, audioData.length);

        int maxAmplitude = getMaxAmplitude(audioData); 

        if (maxAmplitude>32767){
            //  削减波峰
        }else{
            // 继续录制
        }
    }
}

private void stopRecording() {
    isRecording = false;

    if (audioRecord != null) {
        audioRecord.stop();
        audioRecord.release();
        audioRecord = null;
    }
}

// 获取当前录制的音频中的最大振幅
private int getMaxAmplitude(short[] audioData) {
    int maxAmplitude = 0;
    for (int i=0;imaxAmplitude){
            maxAmplitude = Math.abs(audioData[i]);
        }
    }
    return maxAmplitude;
}
