Fresh From the Bench: QuantAsylum QA403 32-bit Audio Analyzer

The QuantAsylum QA403, the 4th generation audio analyzer from the company founded by Matt Taylor in 2012, has a lot to offer. In particular when a user gets tips and guidance from someone like Bob Cordell, no less. The QuantAsylum QA403 Analyzer was the result of a complete redesign imposed by the silicon shortages and supply chain disruptions, pre- and post-pandemic. It appears that the efforts made were well worth it. Jan Didden shares his impressions.

HEAD acoustics ACQUA Adds Listening Effort Prediction Option

November 15, 2024 by audioXpress Staff

HEAD acoustics ACQUA Adds Listening Effort Prediction Option

With LEAP (Listening Effort Prediction from Acoustic Parameters) now integrated into ACQUA 6.1.100, HEAD acoustics offers an optional tool for on-site prediction of the perceived listening effort. The software predicts the perceived listening effort of a listener when hearing an impaired speech signal without the need for an undisturbed reference signal. This makes it possible to carry out measurements more efficiently under laboratory conditions and in real-world applications.
