Why Multiple Audio Track Support

Multiple audio track support opens up a myriad of possibilities for video content creators. By adding different audio tracks, you can:
  • Reach a Global Audience by including multiple language tracks to cater to a diverse audience.
  • Enhance Accessibility by providing descriptive audio for visually impaired viewers.
  • Add Versatilityby including commentary tracks or alternate audio for special editions or director’s cuts.

How it works

​
Separate audio streams

When encoding your video, our system allows the audio stream to be encoded as a separate stream of chunks. This approach is highly recommended as it ensures the audio is in a separate stream and is loaded independently. This separation not only improves loading times but also ensures a seamless and flexible viewer experience.

​
Respecting original files

If your original file already contains multiple audio streams, our system will respect this and display the available audio tracks in the player. This means viewers can easily switch between different audio tracks, such as different languages or dubbing options, enhancing the flexibility and accessibility of your content.

​
Automatic HLS output format

The entire process, from encoding to playback, is streamlined and efficient. All audio tracks and their associated descriptions are automatically transferred to the HLS (HTTP Live Streaming) output format, which is the format we support. This ensures a smooth and consistent viewer experience across all devices and platforms.

Enabling multi-audio support

You can enable multiple audio track support on encoding tab of library settings by toggling Enable Multi Audio Track Support:
