CodecControl Software

This section explains how to use the CodecControl software together with the PCM5122/42 device. For
characteristic performance graphs, refer to the PCM5122/42 data sheet.

3.1

Control Software

The CodecControl software exposes most of the features of a supported TI audio codec EVM through an
intuitive graphical user interface.

NOTE:

Before a PC running Windows can use the TI audio converter EVM as a sound card, the

EVM must be properly configured (sampling rate, audio routing, internal amplifier settings,
etc.) with the CodecControl software. This configuration occurs automatically once an EVM is
detected by the CodecControl software.

CodecControl software in operation.
