5 peak combination means, taking 1 peak as source peak we look at the next 4 peaks, and we calculate each of their frequencies, the time at which they appeared, and time_offset between the source peak and the next 4 peaks.

combinational_peaks

the reason we are doing it just to get more accurate information and making it very sensitive to variation in timings of peaks.

Will it imporve if this number is increased or decreased? or is 5 the best performing one?

well if we increase the number of peak combination: the algorithm might become too sensitive to variations, potentially capturing more detailed information which might be hard to match with recorded audios, since they don't have detailed information, secondly it will also increase our memory usuage therefore reducing our efficiency.

on the other hand, decreasing the number of peak combination, will definitely boost our efficiency, but it may reduce the sensitivity of algorithm potentially leading to loss of detail in audio fingerprinting and thus resulting in inaccurate results.

therefore in order to get a balance between accuracy and efficiency, we choose peak number of combination as 5.
