This article deals with the generation of auditory-inspired spectro-temporal features aimed at audio coding. To do so, we ﬁrst generate sparse audio representations we call spikegrams, using projections on gammatone/gammachirp kernels that generate neural spikes. Unlike Fourier-based representations, these representations are powerful at identifying auditory events, such as onsets, oﬀsets,
