AES International Conference on Automotive Audio – Munich – September 11-13, 2019

Listen is a gold sponsor and exhibitor at the AES International Conference on Automotive Audio in Munich, Germany on September 11-13.

Listen founder and president, Steve Temme, will be presenting a tutorial on ‘Testing Voice-Controlled and Smartphone Integrated Infotainment Systems’ at 2pm on Sept 12th. In this tutorial he will discuss the challenges of implementing audio tests in cars when the signal path is often via a smartphone and/or the car’s own voice-controlled system, and demonstrate how modern test systems can use techniques such as frequency shift and resampling to enable accurate measurement of car audio characteristics ranging from simple frequency and distortion measurements to voice control and communications in the presence of background noise.

On display at the the booth will be various options for testing automotive audio including the SoundCheck test system, Listen’s own audio test hardware, and 3rd party hardware such as 6 microphone arrays and head and torso simulators. On the booth, Listen will also be demonstrating how SoundCheck fully integrates with, and controls, the Mentor A2B interface to enabled rapid automated testing of systems and components that use the A2B bus.

Cupertino SoundCheck Training – Sept 10-11, 2018

training_chicago2017Unleash your audio test skills with our popular 2 day SoundCheck training course in Cupertino, CA on Sept 10-11.

In this class, we start with the basics – how to set up your system, calibrate your hardware and use the virtual instruments.  We then focus on how to develop and modify test sequences, starting with stimulus, analysis and display options, and progressing to more advanced functionality such as sequence loops and jumps, statistics, and advanced post-processing. The class is a combination of classroom-style teaching and hands on practical sessions, so that when you leave the class you will be ready to go in practice as well as in theory.

This hands-on class covers all the major features of SoundCheck version 16, including writing sequences, test signals, analysis, distortion measurements and more. The class is a combination of presentations interspersed with hands-on exercises to ensure that you are comfortable with all the concepts and methods taught before you leave the classroom. Although no previous SoundCheck experience is assumed, the course still offers plenty to users familiar with writing basic sequences.  Content includes:
