TALK TO EXPERTS

Your platform hurts your listeners’ ears

”Hey, the volume difference episode to episode I move to the next video, the ads are so loud my ears hurt.”

“I can’t believe I pay for this service. The volume is ridiculously unstable. PLEASE deal with audio quality!”

”It’s hard to understand the episode because I can not hear the conversations.”

“The volume is lower than other apps. ”

“Okay..the ads are louder that the shows. Are you kidding?”

No one likes to toggling between volume levels when listening to music.
No one likes to offend their ears when a sudden ad blasts through earphones when watching videos. 
This is all about the loudness problem. 

Why loudness normalization is essential for your platform

Loudness is the subjective “feeling” of how we perceive the strength of sound. 
The variance in loudness creates a very inconsistent experience for the viewer or listener. 

Unlike TV broadcasting there is no regulation for loudness normalization on OTT and Music Streaming services so each servcie platforms have different loudness.

As content produced for TV broadcasting are re-transmitted to mobile phones, the ‘Targeted loudness’ applied to these smartphones are unfit.

Not all content creators are audio experts, nor are experts at controlling the volumes with tools they use. 

Advertisers aim at even louder sound than the main programs to catch the interests of their viewers and listeners.
