Schematic of the STRF-based instrument classification. Schematic of the processing stages involved in the STRF-based model of instrument classification. A time-frequency spectrogram is derived for each acoustic signal, then further mapped onto a higher dimensional space using an STRF-based model. The STRF space is then reduced in dimensionality and mapped via a kernel function to a new space to define boundaries between different musical instruments
