Audio Serial Interface Configurations for Audio Codecs
https://www.ti.com/lit/an/slaa469/slaa469.pdf
Each system has different requirements when it comes to interfacing to an audio codec ASI. The most common configurations are the master and slave modes. When the audio codec ASI is configured in master mode, its bit clock (BCLK) and word clock (WCLK) pins are output. In slave mode, BCLK and WCLK are inputs to the codec ASI.

Audio Serial Interface Configurations for Audio Codecs 2.2 ASI Master Mode In master mode, the BCLK and WCLK are outputs from the audio device. These clocks are derived from an external master clock, such as an oscillator, as shown in Figure 5. The ASI bus is derived from the device master clock input which prevents drift between both. Figure 5.
Which serial protocol to output audio using a DAC? - Audio ...
https://forum.arduino.cc/t/which-serial-protocol-to-output-audio-using-a-dac/549656
I store the audio file in a raw format (samples only, no header) in the SD card. For the output, I use an I2C 12 bits DAC module MCP4725 and an LM386 based amplifier. But I can not manage to output sounds above 2 or 3 kHz, which is much to slow for audio. I have read on the web that it comes from the I2C protocol.

To calculate the voltage that this will output from the DAC, we use the following equation: voltage output from DAC = [ (value sent to PORTD) / 255 ] * 5V so for PORTD = 125: voltage output from DAC = ( 125 / 255 ) * 5V = 2.45V The code below sends out several voltages between 0 and 5V and holds each for a short time to demonstrate the concepts I've described above.
Android serial port via audio jack - Stack Overflow

Serial output -> Android audio input -> Sampled square block wave -> digital I/O Please note that most serial levels are either 5V or 3.3V. This will destroy your microphone input! Peak level for consumer audio electronics is usually 1.7V.
How to redirect audio stream to/from the serial port?

Audio must be sampled at twice the maximum frequency, which means that 8 kilobytes per second is about the minimun acceptable rate...and that is the maximum that "normal" RS-232 can do without special line driver hardware.
