The audio passthrough project
A "passthrough" can be viewed as the audio processing equivalent of a "hello world" program. In this section we will program the Nucleo to simply pass the audio samples from the microphone to the DAC.
Highlighted boxes, as shown below, specify a task for which you need to find out the appropriate solution and implementation.
A passthrough is a great sanity check when first beginning with an audio DSP system. Moreover, it serves as a useful starting point for new projects, as we will see in the following chapters when we develop more complicated programs.
