Android 在PlaybackParams应用程序中设置音高

我正在使用AudioManager录制音频

所以，每当我尝试使用setPitch函数设置音调时，我的应用程序就会崩溃

注意：samplerate=8500

这是代码

            buttonPlayLastRecordAudio.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) throws IllegalArgumentException,
                    SecurityException, IllegalStateException {

                buttonStop.setEnabled(false);
                buttonStart.setEnabled(false);
                buttonStopPlayingRecording.setEnabled(true);

                mediaPlayer = new MediaPlayer();
                try {
                    mediaPlayer.setDataSource(AudioSavePathInDevice);
                    mediaPlayer.prepare();
                } catch (IOException e) {
                    e.printStackTrace();
                }

                params.setPitch(samplerate);
                mediaPlayer.setPlaybackParams(params);
                mediaPlayer.start();
                Toast.makeText(MainActivity.this, "Recording Playing",
                        Toast.LENGTH_LONG).show();
            }
        });

下面是错误信息

8500

的“变桨”系数太高了。此参数的安全范围可能介于

0.5

-

3.0

之间（猜测）<代码>1.0对应“无变桨”

不幸的是，我找不到关于实际限制的文件；您可能需要简单地通过捕获异常来确定您提供的值是否超出范围。

不客气。别忘了接受这个答案：）
