An improved time–frequency noise reduction method using a psycho-acoustic Mel model
( Elsevier Inc. , 2018 , Article)This paper addresses the problem of noise reduction in non-stationary signals. The paper first describes a human physiology based time?frequency (TF) representation (HPTF) using Mel filterbanks. It is then used to improve ... -
Time-frequency synthesis and filtering
( Elsevier Inc. , 2016 , Book chapter)This chapter presents methods and techniques to design time-varying linear systems such as filters with precise time-frequency (t,f) specifications; this capability can then allow one to model and predict accurately the ...
