Loudness Normalization

A perfect loudness solution ready for OTT/music streaming.
Our technology reduces the loudness variance between sources to protect our users’ hearing.

Provide an optimal playback experience with consistant loudness.

Key Features

Unlike in typical file-based solutions, the metadata-driven “server-client ” architecture eliminates the need for additional transcoding.

You can set different target loudness for TV and mobile for one source saved in the server.

Mobile devices' inbuilt speakers have weak low-frequency response, resulting in very mild bass sound when music is played. We fixed this problem.

Distinct loudness modes are available based on the platform or service.
