I'm working with the aubio library for sound analysis. Basically to detect onset of beats. aubio.onset() takes 4 arguments, 2 of which are buffer size and hop size. I'm trying to figure how changing these 2 values affects my onset detection.
-B, --bufsize win The size of the buffer to analyze, that is the length
of the window used for spectral and temporal computations. Defaults to 512.
-H, --hopsize hop The number of samples between two consecutive analysis.
Defaults to 256.
The 2 definitions that I found after doing some online search (https://aubio.org/manual/latest/cli.html#aubioonset) are mentioned above.
From my understanding increasing buffer will require more processing time and increase latency. However is there anything else that buffer size will affect.
Also I did not get what the hop size is, in the above definition what do they mean when they say no of audio samples between 2 consecutive analysis. What is the analysis they are performing and what do they do with the audio samples. How will changing the hop size affect my onset detection
