Why Dolby Pulse?
Dolby Pulse offers stunning sound quality at data rates much lower than the rates used in MP3 or standard AAC. With mobile bandwidth at a premium, especially as providers switch to stepped data plans, you’ll appreciate getting great sound at the lowest data rates—not to mention downloads that are up to 400 percent faster than a typical MP3 track download.
Because Dolby Pulse delivers its great quality at low bit rates, it’s more resistant to playback interruptions, tolerating fluctuations in a mobile network’s available bandwidth. The network’s speed may drop, but your music won’t.
Dolby’s built-in loudness control also improves your listening experience. A device that includes a Dolby Pulse decoder can keep volume levels constant from track to track, so you won’t always be reaching for the volume control.
