This paper deals with filtering methods for audio signals using time frequency analysis. The concept of time frequency filtering is vital for the enhancement of non-stationary signals and systems. Time frequency filtering is performed as masking or convolution in the time frequency domain and is based on non-parametric modeling using direct convolution or multiplication. The application of filtering in the time frequency domain for the realisation of artificial reverberation is presented.
