The DE1_SoC has three audio jacks: a line out, a line in, and a microphone jack. In this tutorial, only the line out and microphone in are used. The jacks interface with a Wolfson WM8731 audio CODEC (coder / decoder) chip. This chip has ADCs (analog to digital converters)
Altera University Program Audio core
https://people.ece.cornell.edu/land/courses/ece5760/DE1_SOC/Audio_core.pdf
The Audio core facilitates the transfer of audio data with the Audio CODEC chip on the Altera DE-series boards. Data is transferred serially between the FPGA and the CODEC. However, data written/read to/from the Audio core is transfered in a parallel manner. The Audio core automatically serializes/deserializes the data.

The digital interface of the audio codec sends the digital signal to the Nios II processor and receives the data from the processor. After building the interfaces for the audio codec and the processor, it has been prepared an application in C++ language for the processor that modifies the volume of the signal. The signal come back to the audio ...
