Prediction-driven computational auditory scene analysis
… distinct events in a human listener--the 'auditory scene analysis' of the acoustic information. Recent advances in the understanding of this process from experimental psychoacoustics have led to several efforts to build a computer model capable of the same function. This work is known as …

Noise Robust Pitch Tracking by Subband Autocorrelation Classification
… tracking is one of the elementary tasks of the Computational Auditory Scene Analysis (CASA). While a human can easily listen to the voiced pitch in highly noisy recordings, the performance of automatic speech pitch tracking degrades in unknown noisy audio conditions. Traditional pitch trackers …

Music-listening systems
… proven very difficult to build computer music-analysis tools with similar capabilities. This dissertation examines the psychoacoustic origins of the early stages of music listening in humans, using both experimental and computer-modeling approaches. The results of this research enable the …

Sound-source recognition : a theory and computational model
… of sound-source recognition to the process of auditory scene analysis has largely been neglected by researchers building computational models of the scene analysis process. This thesis proposes a theory of sound-source recognition, casting recognition as a process of gathering information to …

High-resolution sinusoidal analysis for resolving harmonic collisions in music audio signal processing
… collided harmonics. The capabilities of this analysis method are also explored in the context of music signal processing applications. Potential benefits of high-resolution sinusoidal analysis are examined in experiments involving multiple fundamental frequency estimation and audio source …

Speech Enhancement Methods Based on CASA Incorporating Spectral Correlation
Computational auditory scene analysis (CASA) has shown a great potential for speech enhancement compared to some statistical model-based methods. A challenge for CASA is how to estimate binary mask or ratio mask effectively in each time-frequency (T-F) unit. In this thesis, four speech enhancement …
