  journal={Journal of The Audio Engineering Society},
A methodology is introduced for smoothing the complex transfer function of measured responses using well-established or arbitrary fractional-octave profiles, based on a novel time-frequency mapping framework. A corresponding impulse response, also derived analytically, has reduced complexity but conforms to perceptual principles. The relationship be tween complex smoothing and traditional power spectral smoothing is also discussed. 
After fractional-octave smoothing of measured acoustic responses of various spaces, comparisons were undertaken with the original responses using well-established time and frequency domain criteria.
Auditory adapted exponential transfer function smoothing (AAS)
The system-theoretical foundation of a smoothing procedure referred to as auditory adapted exponential smoothing (AAS) is derived, which is adapted to the spectral properties of the human hearing system by implementing frequency-dependent smoothing bandwidths.
Room equalization based on iterative simple complex smoothing of acoustic impulse responses
Results from an audio-conferencing reverberant room using objective and subjective tests show that the iterative simple complex smoothing of measured acoustic impulse responses can improve the measured and perceived quality of audio reproduction.
In this paper, we investigate different types of spectral smoothing of the transfer function of single-channel noise reduction algorithms in terms of achieved audio quality. In order to determine the
Warped, Kautz, and Fixed-Pole Parallel Filters: A Review
In audio signal processing, the aim is the best possible sound quality for a given computational complexity. For this, taking into account the logarithmic frequency resolution of hearing is a good
Blind single-channel suppression of late reverberation based on perceptual reverberation modeling.
Objective and subjective measures indicate that the proposed method achieves significant late reverberation suppression for both speech and music signals over a wide range of reverberation time (RT) scenarios.
Blind Single-Channel Dereverberation for Music Post-Processing
The results show that the proposed dereverberation approach efficiently suppresses reverberation without introducing significant processing artifacts and the method is appropriate for the post-processing of music recordings.

Investigation on Localization Performance Using Smoothed Individual Head-Related Transfer Functions
A characteristic feature of head-related transfer functions (HRTFs) are narrow spectral dips which are mainly caused by resonances of the concha. The resulting dynamic range may be problematic in


Time-frequency mapping based on non-uniform smoothed spectral representations
A theoretical model for non-uniform spectral smoothing is introduced allowing the choice of arbitrary frequency resolution profiles to match such auditory features and this generalized framework is extended to allow mapping of such smoothing spectra into the time domain.
A Time-Frequency Auditory Model Using Wavelet Packets
It is shown that the change in the time-frequency excitation pattern introduced when a test tone at masked threshold is added to the masker is approximately equal to 7 dB for all types of maskers, and the classic detection ratio therefore overrates the detection efficiency of the auditory system.
Comparison of Loudspeaker Equalization Methods Based on DSP Techniques
Methods of loudspeaker response equalization using digital filters are compared. In addition to generally known methods and techniques a recently introduced new principle, based on warped filters, is
A Capon's time-octave representation application in room acoustics
A new method combining both Capon's estimator and a time-octave representation is proposed to obtain legibility in the time frequency plane using a variable frequency resolution with a fixed time resolution.
