Using the Audio Processor Workbench (APWorkbench)
Introduction
The Audio Processor Workbench (APW) has been designed as a multi-device software
control panel supporting all the products in the Sound Terminal
®
family from
STMicroelectronics.
APW has been developed to fit the needs of both the beginner and the experienced user.
The tool is quite flexible and its configuration can be simple or more advanced in order to
access the multitude of features offered by the Sound Terminal
®
products.
Features of the APW include:
■ I
2
C register control: direct R/W access to all I
2
C registers of the device.
■ Equalizer editor: a powerful graphic tool to design filters (or a chain of them) and to
download their coefficients directly into the device. APW makes the use of any other
external tool unnecessary, thus simplifying device operation.
■ Configuration presets: the capability of storing up to 8 device configurations that can be
loaded just by pushing a button. Thanks to this feature the configuration process becomes
a rare activity making device testing, measuring or listening faster than ever.
■ Device common controls: embedded or external bridge power-up, device reset, power-up
and initialization.
■ Device-specific controls: the ST Sound Terminal
®
product family includes many devices.
APW offers the control of all the various device-specific features (proprietary audio
effects, I/O configuration and routing and so on).
