Audio Channels

Audio channels represent the number of independent sound channels used in an audio file, such as mono (1 channel) or stereo (2 channels). Multi-channel audio is commonly used to enhance user experience.

Why do we test it?

Verifying the correct number of audio channels is critical to ensuring the creative functions as intended across devices and environments. Ads that incorrectly use multi-channel audio might experience compatibility issues or degrade the user experience. This test ensures the right audio channel configuration, optimizing for both performance and playback quality across platforms.
