Modulation frequency analysis has been studied predominantly in research areas such as
communications, filtering and coding of digital signals, and representations of neurons in the …

Voice based call centers enable customers to query for information by speaking to agents in
the call center. Most often these call conversations are recorded for analysis with the intent …

Modulation frequency features have shown promise in representing distinguishing
characteristics of audio signals. The modulation spectrum, which is described as an acoustic …

In this paper, we explore a nonlinear AM-FM model to extract alternative features for music
instrument recognition tasks. Amplitude and frequency micro-modulations are measured in …

Beat detection systems are widely used in the music information retrieval (MIR) research
field for the computation of tempo and beat time positions in audio signals. One of the most …
