Question

I have this code.

  private static Map> alternativeMethod(AudioFormat audioformat, 
      List listChu

Does this work for you?

public static Map<Long, List<TimePitchValue>> alternativeMethodme(
        AudioFormat audioformat, List<ChunkDTO> listChunkDTO,
        long index, int sizeChunk) {

    int numBytesPerSample = audioformat.getSampleSizeInBits() / 8;
    int quantitySamples = sizeChunk / numBytesPerSample;
    long baseTime = quantitySamples * index;

    return IntStream.range(0, quantitySamples).boxed()
            .collect(Collectors.toMap(time -> baseTime + time,
                    time -> listChunkDTO.stream()
                            .map(chunkDTO -> new TimePitchValue(
                                    chunkDTO.getPitch(),
                                    baseTime + time,
                                    extractValue(
                                            chunkDTO.getChunk(),
                                            numBytesPerSample,
                                            time)))
                            .sorted(Comparator.comparingInt(
                                    TimePitchValue::getValue)
                                    .reversed())
                            .collect(Collectors.toList()),
                            (a,b)->a,
                            LinkedHashMap::new));
}

I think I finally figure this out. I had to do some rearanging of methods and such.

Updated. I added the sort and returned the map as a LinkedHashMap
