我是使用Xamarin和C#进行Android开发的新手。我正在尝试录制高质量的音频，放大它，然后立即播放。到目前为止，我能够使用“AudioRecord”和“AudioTrack”对象进行录制和播放，但在音频质量和放大方面没有运气。以下是代码...

private void RecordAndPlayback()
{
    int recordingSampleRate = AudioTrack.GetNativeOutputSampleRate(Stream.Music);
    recordingSampleRate = System.Math.Max(recordingSampleRate, instance.SelectedSamplingRate);
    bufferSize = AudioRecord.GetMinBufferSize(recordingSampleRate, ChannelIn.Stereo, Android.Media.Encoding.Pcm16bit);

    buffer = new byte[bufferSize];

    audioRecord = new AudioRecord(AudioSource.Mic, recordingSampleRate, ChannelIn.Stereo, Android.Media.Encoding.Pcm16bit, bufferSize);

    audioTrack = new AudioTrack(Stream.Music, recordingSampleRate, ChannelOut.Stereo, Android.Media.Encoding.Pcm16bit, bufferSize, AudioTrackMode.Stream);

    audioTrack.SetPlaybackRate(recordingSampleRate);

    audioRecord.StartRecording();
    audioTrack.Play();

    while (isListening)
    {
        audioRecord.Read(buffer, 0, buffer.Length);
        audioTrack.Write(buffer, 0, buffer.Length);
    }
}

有没有人能请指导我在这方面记录音频与更好的质量，并可能放大音频音量，而播放它回来？
提前感谢：）
