SECTION 3 – PROGRAMMING THE ADAV4601

DESIGNING AND DEVELOPING

This section describes how it is possible to control the ADAV4601 audio processor and evaluation board with the
software supplied.
If the customer wishes to develop their own custom audio flow. Analog Devices, Inc. offers an award-winning
graphical programming tool (SigmaStudio™) that allows custom flows to be quickly developed and evaluated. This
allows the creation of customer-specific audio flows, including use of the Analog Devices library of third-party
algorithms. This means that the customer can tailor the audio processing to their own specific needs and
requirements.
Alternatively, the ADAV4601, by default, loads a dedicated TV audio flow that incorporates full matrix switching (any
input to any output), automatic volume control that compensates for volume changes during advertisements or
when switching channels, dynamic bass, a multi-band equalizer, and up to 200 ms of stereo delay memory for
audio-video synchronization. This audio flow is loaded by default when the part is powered on. To support and
control this audio flow, it is possible to use the SigmaStudio programming tool to perform I
ADAV4601 to enable the device and control the audio flow registers.
Figure 14 shows both methods of controlling the audio processing, using either the default flow on the chip or
developing a new unique flow. Instructions for both methods are included in this section.
