Abstract: Various examples disclosed herein relate to digital signal processing, and more particularly, to identifying metrics of audio samples to dynamically adjust the gain of audio data. In an example embodiment, a pulse density modulation system is provided that includes sample generation circuitry and gain control circuitry coupled to the sample generation circuitry. The sample generation circuitry is configured to sample audio data to produce samples of the audio data and output the samples to a processor and to the gain control circuitry. The gain control circuitry is configured to determine one or more metrics based on the samples of the audio data and output the one or more metrics to the processor.
