[aubio-user] Doubt about pitch in non periodic region

[Tanmayee Joshi]

Hi,

I am Tanmayee Joshi. I am working on music tracking in audio streams of
movies. Aubiopitch gives the values of pitch corresponding to time. I have
a doubt whether Aubio gives additional information about pitch in non
periodic regions, since, pitch is undefined for non periodic regions. Does
it give any result in the form, like, values 0 or -1 for non periodic
regions?

I came across two papers which have used Aubio tool for this purpose and
they have mentioned that aubiopitch does give this additional information.
I went through the documentation of Aubio but couldn't find it. Please help.

Papers:
1. T. Guha, N. Kumar, S. S. Narayanan, and S. L. Smith, “Computationally
deconstructing movie narratives: an informatics approach,” in Acoustics,
Speech and Signal Processing (ICASSP), 2015 IEEE International Conference
on. IEEE, 2015, pp. 2264–2268

2. Kataria, Saurabh, and Abhay Kumar. "Scene Intensity Estimation and
Ranking for Movie Scenes Through Direct Content Analysis."

Thanking you,
Tanmayee Joshi
