Abstract
A framework is presented for increasing the computational efficiency of STFT analysis by sacrificing the quality of each signal frame´s DFT in terms of SNR, frequency resolution, and frequency coverage. The resulting algorithms are dominated by a frame-adaptive vector summation process designed to ensure that the number of additions per frame does not exceed any desired limit
