CODECs 
Stereo Audio CODECs
ESS Stereo CODEC solutions combine ESS Technology’s renowned SABRE signature sound with world-class specifications of our digital to analog (DAC) and Analog to Digital (ADC) converters.
These CODECs allow for a multitude of solutions with the addition of PGAs, PowerLine Drivers (Line Driver/Headphone Amplifier), Audio Signal Processors (ASP/ASP2), Jack detection, Microphone Bias, Analog PLLs, and Master SPI interfaces.
The ES9291 incorporates the ASP2, a 2nd generation Audio Signal Processor. With the combination of ESS’ SABRE Intelligence Studio (SI Studio) GUI interface with simplifies programming the ASP2, multi-band PEQs, MIXERs, DRC, AGL and specialty filters such as RIAA and cross-overs, allowing for quick to market solutions.

USB Audio CODECs
ESS USB audio solutions combine the legendary sound quality of ESS SABRE® DACs with easy-to-use solutions for headsets and dongles. The products feature best-in-class specifications and high-power outputs capable of supporting the most demanding of headphones. Jack detect functionally allows for easy use in USB-C Dongles. And the integrated ADC’s and PDM inputs enable recording inputs or ANC microphones.
MQA (Master Quality Authentication) renderer that makes MQA playback easy and cost efficient. MQA rendering is an ideal fit for USB-C headsets because an increasing number of software decoders support MQA core decode. Enabling the MQA rendering requires no additional design work for the headset maker.
The ESS Audio Signal Processor allows for advanced audio filters for Programmable Equalizers (PEQ), sidetone or other custom designs.
