Without the research performed by individual scientists and organisations into audio forensics, no such field would exist. It is the research conducted by Bell Labs to develop the spectrogram during the Second World War that paved the way for the field, and it is essential that research continues and further methods are developed as technology continues to evolve and new devices, software, and audio formats ...
