Flexible, cost effective and enhanced experience for industry and end-users

ETSI, the leading ICT standards organization, has released this month AC-4 the next generation digital audio compression standard for tomorrow’s media delivery environments, offering the flexibility to support future audio experiences.

From TVs to home theatres, from computers to mobile phones and online streaming, this innovative codec offers an advanced sound experience for all users’ entertainment including video games.
