Audio Compression

Audio compression reduces the size of an audio file by using algorithms to remove inaudible or unnecessary data, making the file easier to transmit and store.

Why do we test it?

Optimizing audio compression ensures that the file size remains manageable without sacrificing audio quality. Over-compression can result in low-quality sound that could deter users, while under-compression may result in slower loading times. This test ensures that audio is adequately compressed to maintain a balance between quality and performance, which is vital for high-quality ad playback.
