Audio Codec

The audio codec compresses and decompresses digital audio data. Today's widely accepted standard is AAC for audio ads.

Why do we test it?

Choosing the correct codec is vital because not all browsers or devices support every codec. Testing the codec ensures compatibility, preventing playback issues that could affect user engagement with the ad. This validation helps avoid situations where audio fails to play correctly, leading to poor ad performance.
