Audyssey Develops Headphone Technology For Mobile Devices

By Joseph Palenchar On May 10 2013 - 3:40pm




Los Angeles – Audyssey has developed audio technologies that headphone suppliers can use to optimize the sound output of specific headphone models connected to smartphones and tablets.

The technologies also maintain perceived bass response that would normally be lost at lower listening levels.

Via a smartphone or tablet app, consumers would be able to select the model of headphone they are using to tailor sound to the acoustic characteristics of that particular headphone. Data about each headphone’s acoustic characteristics would be stored in the Cloud and accessed by the app, whose menu would include different headphone models that users would select.

The acoustics profiles can be incorporated in Audyssey’s own Media Player app for iOS devices, in streaming-service apps, or in a turnkey iOS media player app that headphone makers could provide.

To enable headphone makers to take advantage of the technologies, Audyssey developed

the ExpertFit measurement and evaluation program. With it, headphone suppliers create a unique profile for each pair of headphones using new algorithms developed by Audyssey. The algorithms are based on the company’s existing MultEQ and Dynamic EQ technologies for home audio systems.

  The tools enable headphone suppliers to create filters to tailor the output of a specific headphone model to account for the headphone’s acoustical characteristics and human perception, a spokesman said.

  The filters created by the Audyssey tools would become part of a headphone profile and would be used when listening through an app running Audyssey’s SDK, the company said.

  The technology derived from Audyssey’s MultEQ technology measures a reference mixing environment, capture its characteristics, measures each headphone individually, and applies an EQ filter to match the headphone output to the reference environment, a spokesman explained.

 The technology derived from Dynamic EQ would enable users “to listen at more reasonable levels compared to the ear-splitting studio levels and maintain the proper [frequency-response] balance that would normally be lost because of human perception changes at lower listening volumes,” the spokesman added.
