Converting I2S/PCM Captures into Audio - Saleae Support
https://support.saleae.com/faq/technical-faq/convert-i2s-pcm-to-audio
Comparing an I2S/PCM Capture with an Existing Audio File Once you have captured I2S audio data and have configured the I2S protocol analyzer successfully, you will need to export the I2S protocol results to a CSV file. You will then need to convert the reference WAV file to CSV.
audio - I2S and PCM format - Stack Overflow
https://stackoverflow.com/questions/32367619/i2s-and-pcm-format
PCM is a digital representation of an audio signal. It can be stored in memory or written on paper or whatever. An example of a 16-bit PCM audio sample might be something like 0x0152. I2S is a electrical serial interface used to transmit PCM data from one device to another.

This PCM data is then downsampled by a factor of 4, and written to the I2S TX_FIFO where 16 bit words are output at a frame rate of 7.963kHz. More specifically, two separate DMA transfers are used to transfer data output by the PDM to PCM converter to an audio buffer, and from the audio buffer to the I2S TX_FIFO.

PCM: I2S: As you can see the PCM format has a frame sync pulse, then goes the data. In the case of the SIM module, it sends only one word of audio, with the rest being a long sequence of zeroes, while in I2S there is the WSL/LCK line going high and low depending on the channel selected. Logged.

Dynamic PCM — The Linux Kernel documentation
https://www.kernel.org/doc/html/v4.16/sound/soc/dpcm.html
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.
