Tarsos是一个开源的音频处理库,它提供了一系列用于音频分析和处理的工具和算法。Tarsos Android库是Tarsos库的Android版本,它可以在Android平台上进行音频处理。
使用Tarsos Android库从麦克风中流式获取音频并添加效果,然后保存到WAV文件的步骤如下:
dependencies {
implementation 'be.tarsos:dsp:2.4-SNAPSHOT'
}
AudioRecorder
。在该类中,你需要使用Android的AudioRecord
类来获取麦克风的音频数据。以下是一个简单的示例:import android.media.AudioFormat;
import android.media.AudioRecord;
import android.media.MediaRecorder;
public class AudioRecorder {
private static final int SAMPLE_RATE = 44100;
private static final int CHANNEL_CONFIG = AudioFormat.CHANNEL_IN_MONO;
private static final int AUDIO_FORMAT = AudioFormat.ENCODING_PCM_16BIT;
private AudioRecord audioRecord;
private boolean isRecording = false;
public void startRecording() {
int bufferSize = AudioRecord.getMinBufferSize(SAMPLE_RATE, CHANNEL_CONFIG, AUDIO_FORMAT);
audioRecord = new AudioRecord(MediaRecorder.AudioSource.MIC, SAMPLE_RATE, CHANNEL_CONFIG, AUDIO_FORMAT, bufferSize);
audioRecord.startRecording();
isRecording = true;
}
public void stopRecording() {
if (audioRecord != null) {
isRecording = false;
audioRecord.stop();
audioRecord.release();
audioRecord = null;
}
}
public byte[] readAudioData() {
byte[] buffer = new byte[1024];
audioRecord.read(buffer, 0, buffer.length);
return buffer;
}
public boolean isRecording() {
return isRecording;
}
}
AudioProcessor
。在该类中,你可以使用Tarsos Android库提供的音频处理工具和算法来添加效果。以下是一个简单的示例,演示了如何将音频保存为WAV文件:import be.tarsos.dsp.AudioDispatcher;
import be.tarsos.dsp.io.TarsosDSPAudioFormat;
import be.tarsos.dsp.io.android.AndroidAudioInputStream;
import be.tarsos.dsp.io.android.AudioDispatcherFactory;
import be.tarsos.dsp.io.android.AudioPlayer;
import be.tarsos.dsp.io.android.WaveformWriter;
public class AudioProcessor {
private AudioDispatcher dispatcher;
private WaveformWriter writer;
public void processAudio(byte[] audioData) {
if (dispatcher == null) {
TarsosDSPAudioFormat format = new TarsosDSPAudioFormat(SAMPLE_RATE, 16, 1, true, false);
AndroidAudioInputStream inputStream = new AndroidAudioInputStream(audioData, format);
dispatcher = new AudioDispatcher(inputStream, 1024, 0);
writer = new WaveformWriter(format, "output.wav");
}
// 添加效果的代码
writer.process(dispatcher);
}
public void saveAudio() {
if (dispatcher != null && writer != null) {
writer.stop();
dispatcher.stop();
dispatcher = null;
writer = null;
}
}
}
AudioRecorder audioRecorder = new AudioRecorder();
AudioProcessor audioProcessor = new AudioProcessor();
audioRecorder.startRecording();
// 循环读取音频数据并处理
while (audioRecorder.isRecording()) {
byte[] audioData = audioRecorder.readAudioData();
audioProcessor.processAudio(audioData);
}
audioRecorder.stopRecording();
audioProcessor.saveAudio();
这样,你就可以使用Tarsos Android库从麦克风中流式获取音频,添加效果并保存到WAV文件了。
请注意,以上示例仅为演示目的,实际使用时你可能需要根据你的需求进行适当的修改和扩展。另外,Tarsos Android库还提供了许多其他功能和算法,你可以根据需要进行进一步的探索和使用。
