java中使用MappedByteBuffer将 File类转ByteBuffer

Posted 2022-09-08 passedbylove

public static WavFile openWavFile(File file) throws IOException, WavFileException
    
        FileChannel channel = new FileInputStream(file).getChannel();

        MappedByteBuffer mappedByteBuffer = channel
                .map(FileChannel.MapMode.READ_ONLY, 0, channel.size());
        return openWavFile(mappedByteBuffer);
    
public static WavFile openWavFile(ByteBuffer buffer) throws IOException, WavFileException
