This test sequence demonstrates SoundCheck’s Triggered Record – Chirp Trigger function for open loop testing of devices without analog inputs such as smart speakers, wearables, smart home devices, tablets and cellphones. A stimulus WAV file is created in SoundCheck and transferred to the device under test, where it is played back and the response recorded in SoundCheck as if the stimulus were played directly from SoundCheck. The Acquisition step is triggered by the chirp in the stimulus file. Chirp triggers are more robust than level and frequency triggers which are susceptible to false triggering due to background noise.
This years AISE (ALMA International Symposium & Expo) will be held on June 9-10 in Orlando, FL. Listen will be showcasing its suite of audio measurement equipment for measuring smart speakers, wearables, smart home audio, hearables and automotive audio, as well as conventional transducers such as loudspeakers, headphones and microphones.
In addition to exhibiting, Steve Temme will present a half-day seminar on smart speaker testing. This informative and educational seminar will discuss the challenges of testing smart devices such as smart speakers, smart home devices, wearables and more, and demonstrate various methods of testing such devices. Steve Temme will also present a paper on testing smart hearable devices, and Les Quindipan will demonstrate automotive audio testing using the Mentor A2B interface with SoundCheck.
