我有一些问题,将音频数据存储在一个字节数组中,将其转换为大端短数组,对其进行编码,然后将其更改回字节数组.这就是我所拥有的.原始音频数据存储在audioBytes2中.我使用相同的格式进行解码,而cos函数则使用减号.不幸的是,更改字节和短数据类型是不可协商的.

    short[] audioData = null;
    int nlengthInSamples = audioBytes2.length / 2;
    audioData = new short[nlengthInSamples];

    for (int i = 0; i < nlengthInSamples; i++) {
       short MSB = (short) audioBytes2[2*i+1];
       short LSB = (short) audioBytes2[2*i];
       audioData[i] = (short) (MSB << 8 | (255 & LSB));
    }

    int i = 0;
    while (i < audioData.length) {
        audioData[i] = (short)(audioData[i] + (short)5*Math.cos(2*Math.PI*i/(((Number)EncodeBox.getValue()).intValue())));
        i++;
    }

    short x = 0;
    i = 0;
    while (i < audioData.length) {
        x = audioData[i];
        audioBytes2[2*i+1] = (byte)(x …

我发现将一个短数组转换为字节数组,将字节数组转换为短数组,但不是短数组转换为字节数组.

以下是导致转换的代码

while(!stopped)
        { 
            Log.i("Map", "Writing new data to buffer");
            short[] buffer = buffers[ix++ % buffers.length];

            N = recorder.read(buffer,0,buffer.length);
            track.write(buffer, 0, buffer.length);

            byte[] bytes2 = new byte[N];

我试过了

              int i = 0;
              ByteBuffer byteBuf = ByteBuffer.allocate(N);
              while (buffer.length >= i) {
                  byteBuf.putShort(buffer[i]);
                  i++;
        }

bytes2 = byteBuf.array();

和

    ByteBuffer.wrap(bytes2).order(ByteOrder.LITTLE_ENDIAN).asShortBuffer().put(buffer);

但是我在两者上都收到了这个错误(错误如果不完全相同但两者非常相似):

并且只是在这里提供尽可能多的信息是使用字节数组之后的代码

                read(bytes2, …
