Abstract: Filter banks with fixed time-frequency resolution, such as STFT, are a common tool for many audio analysis and processing applications allowing effective implementation via FFT. The major problem with STFT approach is a fixed time-frequency resolution. In this paper, we suggest adaptively varying STFT time-frequency resolution in order to reduce filter bank specific artifacts such as pre-echo while retaining adequate frequency resolution. Several strategies for systematic adaptation of time-frequency resolution are proposed. The introduced approach is demonstrated for problems of spectrograms display, noise reduction, and spectral effects processing.
