A transient-aware frequency domain audio processor

In this paper, the implementation of a transient-aware, discrete-time audio processor is presented. The processing takes place in the Short Time Fourier Transform (STFT) domain, using a variant of the well known overlap-add technique. The proposed method identifies the presence of transients in the input signal and constantly adapts the analysis-synthesis frame size. Hence, the proposed technique ensures optimal time or frequency resolution, depending on the intrinsic characteristics of each processing frame.
