1. An audio processing device comprising:
memory storing audio input including human speech and in a form of initial samples with a first bit-size; and
at least one processor communicatively coupled to the memory to operate by:
dividing at least one of the initial samples into multiple sample parts;
generating at least one gain formed by at least one neural network accelerator;
applying the at least one gain to at least one of the sample parts to form at least one scaled sample part; and
generating a scaled output sample in a second bit-size comprising combining at least portions of the multiple sample parts including the at least one scaled sample part, and wherein a portion of one of the sample parts being combined has most significant bits (MSBs) of the initial sample and a portion of another one of the sample parts being combined has least significant bits (LSBs) of the initial sample.
