## What is Miso AV Lab?

Miso AV Lab is an audio and video test bench for iPhone and iPad. Identify each loudspeaker up to 7.1, play an Atmos file on your height speakers, show reference patterns and HDR windows, check motion, and line up picture and sound. You judge each test by eye and ear.

The download includes Discovery, the information pages, and some tests. The Full Catalogue in-app purchase adds the rest.

INCLUDED WITH THE DOWNLOAD

• Brightness probe: raises a window’s brightness and shows the reported peak and sustained headroom
• Motion probe: measures the frame rate the display link delivers, including the slowest sustained rate
• Channel identification at 5.1 and at the layout matching your output
