The APWorkbench software suite provides a comprehensive environment for the customer to explore, evaluate and configure devices within ST’s product portfolio for audio applications, including stereo and multi-channel amplifiers, DSP and digital MEMS microphones. The tool represents a unique solution enabling the user to conveniently evaluate, configure and tune advanced audio IPs embedded in ST’s Sound Terminal®products. Custom controls and a user-friendly graphical interface expose the complexity of today's audio devices in a simple and intuitive manner, guiding the novice through the basic configuration steps and providing acoustic expertise to tune the devices for optimal performance.
The Sound Terminal®demonstration boards can be thoroughly controlled by APWorkbench through a USB-connected interface (APWLink, STEVAL-CCA035V1).
Digital MEMS microphones can be evaluated using a specific demonstration kit, based on the STA321MP microphone processor (STSmartVoice demonstration board, STEVAL-MKI126V1 or STEVAL-MKI126V3), and connected to the PC via a USB interface (STAudioHub interface, STEVAL-MKI138V1). The STSmartVoice kit is digitally controlled by APWorkbench and the sound recorded from the microphones can be analyzed and visually represented by means of real-time virtual instrumentation (oscilloscopes, spectrum analyzers, etc.). Up to six digitally connected microphones can be processed. This comprehensive microphone kit, enhanced by the APWorkbench suite, represents a unique solution on the market and enables a digital MEMS microphone offering for the mass market.
