Abstract:
This paper presents a time-domain technique based solely on simple operations, like filtering and scaling, to continuously track a sound descriptor correlated to brightness and pitch.
In opposition to existing algorithms this approach does not rely on input framing or frequency-domain transforms, ensuring a better temporal resolution and the possibility to model analog-like implementations.
In the first part of the document we present the details of our approach to brightness estimation; then we will compare CoBE to the brightness estimation implemented in MIR Toolbox; we introduce and define the concept of ``Equivalent Brightness Frequency'' (EBF) and finally we show how to exploit CoBE and EBF to obtain a rough monophonic pitch estimator or an efficient pre-processor for zero crossing rate (ZCR) pitch trackers.
