I found a video on youtube that detects the graphic of an audio so I thought of creating a comparison program and not recognition where I have two audios with the same word but with two sizes 0:03 and 0:02 and compare the audios by the result of the picturebox and create a margin of error of 30% and maximum length for each then it would be possible to compare these two different audio files or they would always give me results that are different or always the same and what factors would lead to that The goal is just to compare and say they look but maybe they are not the same audios, the recognition has other metrics so it is a theoretical idea.

Concept:

Wave1.wav | 2kb
wave2.wav | 3kb

wave1 different of wave2

Wave1 sound wave exemple: (...\.\.\....\.\.\.\\..\..\****...)
Wave2 sound wave exemple: (...\.\.\....\.\.\.\\..\..\****...\..\..\.**)

the above concept helps to understand the simulated compliance are similar but one is bigger and the other smaller but excluding the margin and other possibilities it is possible to know with 70% chances that audios are equal ?
