The Low-Complexity Acoustic Scene Classification task is making a comeback in DCASE 2022 Challenge, this time with new constraints: classification decision needs to be done in 1-second segments, the maximum number of parameters allowed is 128K in INT8, and the system should have maximum 30 MMAC (million MACs) per inference.
