Dynamic PCM — The Linux Kernel documentation

Dynamic PCM allows an ALSA PCM device to digitally route its PCM audio to various digital endpoints during the PCM stream runtime. e.g. PCM0 can route digital audio to I2S DAI0, I2S DAI1 or PDM DAI2. This is useful for on SoC DSP drivers that expose several ALSA PCMs and can route to multiple DAIs.

The DPCM (Differential PCM) encodes the PCM audio values as the differences between the actual and predicted values of the input signal. An algorithm predicts the next sample based on the previous samples, and the encoder …

DPCM (Differential Pulse Code Modulation) i. Adjacent audio samples tend to be similar in much the same way that neighboring pixels in an image tend to have similar colours. ii. The simplest way to exploit this redundancy is to subtract adjacent samples and code the differences, which tend to be small integers.
