如何使用Java将OGG文件转换为WAV文件？

针对Telegram语音消息（OGG格式）转WAV以适配微软语音转文本Java SDK的需求，以下是三种可行的实现方案：

方案一：FFmpeg命令行调用（稳定高效） #

借助FFmpeg处理音频格式转换，需确保运行环境已安装FFmpeg。转换时指定微软SDK要求的PCM参数：

import java.io.IOException;

public class OggToWavConverter {
    public static void convertOggToWav(String oggFilePath, String wavFilePath) throws IOException {
        ProcessBuilder processBuilder = new ProcessBuilder(
            "ffmpeg",
            "-i", oggFilePath,
            "-acodec", "pcm_s16le",
            "-ar", "16000",
            "-ac", "1",
            wavFilePath
        );
        Process process = processBuilder.start();
        try {
            int exitCode = process.waitFor();
            if (exitCode != 0) {
                throw new RuntimeException("FFmpeg转换失败，退出码: " + exitCode);
            }
        } catch (InterruptedException e) {
            Thread.currentThread().interrupt();
            throw new RuntimeException("转换被中断", e);
        }
    }
}

方案二：纯Java库TarsosDSP（无外部依赖） #

使用TarsosDSP纯Java音频处理库，无需安装外部工具，适合轻量场景：

先添加Maven依赖 #

<dependency>
    <groupId>be.tarsos.dsp</groupId>
    <artifactId>tarsos-dsp</artifactId>
    <version>2.4.0</version>
</dependency>

转换代码 #

import be.tarsos.dsp.AudioDispatcher;
import be.tarsos.dsp.io.jvm.AudioDispatcherFactory;
import be.tarsos.dsp.io.jvm.WaveWriter;
import java.io.File;
import java.io.IOException;

public class OggToWavConverter {
    public static void convertWithTarsos(String oggPath, String wavPath) throws IOException {
        AudioDispatcher dispatcher = AudioDispatcherFactory.fromPipe(oggPath, 16000, 1024, 0);
        WaveWriter waveWriter = new WaveWriter(new File(wavPath), 16000, 1);
        dispatcher.addAudioProcessor(waveWriter);
        dispatcher.run();
    }
}

方案三：JAVE2封装库（跨平台友好） #

JAVE2封装了FFmpeg功能，自动适配不同系统的native库，无需手动安装FFmpeg：

添加Maven依赖 #

<dependency>
    <groupId>ws.schild</groupId>
    <artifactId>jave-core</artifactId>
    <version>3.1.1</version>
</dependency>
<!-- 根据运行系统选择对应native依赖，示例为Windows x64 -->
<dependency>
    <groupId>ws.schild</groupId>
    <artifactId>jave-nativebin-win64</artifactId>
    <version>3.1.1</version>
</dependency>

转换代码 #

import ws.schild.jave.Encoder;
import ws.schild.jave.EncoderException;
import ws.schild.jave.MultimediaObject;
import ws.schild.jave.encode.AudioAttributes;
import ws.schild.jave.encode.EncodingAttributes;
import java.io.File;

public class OggToWavConverter {
    public static void convertWithJave(String oggPath, String wavPath) throws EncoderException {
        File source = new File(oggPath);
        File target = new File(wavPath);

        AudioAttributes audio = new AudioAttributes();
        audio.setCodec("pcm_s16le");
        audio.setBitRate(16000);
        audio.setChannels(1);
        audio.setSamplingRate(16000);

        EncodingAttributes attrs = new EncodingAttributes();
        attrs.setFormat("wav");
        attrs.setAudioAttributes(audio);

        Encoder encoder = new Encoder();
        encoder.encode(new MultimediaObject(source), target, attrs);
    }
}

关键注意事项 #

• 微软语音转文本SDK要求WAV格式为PCM 16位、单声道、16kHz采样率，所有方案均已按此配置参数，请勿随意修改。
• 处理Telegram语音时，需先将文件从Telegram服务器下载至本地，再执行转换，转换完成后再传入微软SDK进行转写。
