I'm working on a project related to fingerprinting of audios with different sizes. The library that I'm using is called Dejavu. Generally, it is the implementation of this paper that hashes the relationship between peaks of audio samples and uses it for further identification.
Because the number of peaks in an audio sample is correlated with its length, a shorter sample means, fewer peaks which also means less information for the identification. I wonder is there any additional resource or methodology that you can suggest for the identification of short audio (less than 1 second) samples.
