Omnifone's catalogue of 6.5m tracks will encoded into the Dolby Pulse format.
Dolby Laboratories president and CEO Kevin Yeaman says, "As digital content services and networked devices become part of our day-to-day lives, the ability to deliver digital content in the most efficient file format becomes increasingly important."
Omnifone CEO Rob Lewis adds, "Consumers demand great sound quality, fast downloads, and streaming, and want to be able to store more media on their connected devices. Omnifone's decision to encode tracks using Dolby Media Generator into the Dolby Pulse format in 2010 will deliver highly efficient track sizes, faster delivery speeds, and higher sound quality per megabyte than traditional formats like MP3."
The new format is being backed by all four major labels.
