DSP allows absolute control over the audio signal, enabling the design of advanced technologies that can enhance the listening experience in any context.

Meridian Lossless Packing

Meridian has been a long term collaborator and technology partner with Dolby. Meridian Lossless packing technology was developed by Meridian and licensed to Dolby as the standard for DVD audio.

Master Quality Authenticated

Meridian developed MQA - the revolutionary technology for efficiently streaming music with the highest possible sound quality. With MQA you can be sure that you’re hearing exactly what the artist approved in the studio.

Headphone Spatial Processing

Sound with a Realistic Sense of Space

Meridian's Headphone Spatial Processing (HSP) overcomes the challenges of headphone listening such as their compact size and lack of 'crosstalk' between the left and right channels. HSP not only recreates a realistic soundstage that simulates the experience of listening to real loudspeakers, but it also delivers vocals with pristine clarity. This is a fresh listening experience helping you forget you are wearing earbuds.
