User Reviews

AV Sync is a helpful Android app for live audio-video synchronization testing, commonly used to measure and adjust audio delay on TVs and home theater systems. Users praise its effectiveness and ease of use in troubleshooting devices. However, it only supports live recordings, not video uploads, lacks detailed instructions and calibration options, and has limited frame rate support. Some find the interface and flashing visuals a bit confusing or uncomfortable, but overall it fills a unique and useful niche for managing AV sync issues.

Pros

Helps effectively measure and adjust audio delay with visual cues, aiding in troubleshooting AV sync issues.
Works well in live synchronization scenarios, such as syncing TV audio with external devices.
App is appreciated by users for its unique function in audio-video synchronization, filling a niche on Android.
Easy to use when paired with external test channels or devices like Fire TV and home theater systems.
Provides useful results to identify if audio delay problems are caused by devices like TVs or receivers.

Cons

Does not support uploading or editing existing videos to sync audio and video, only works for live recordings.
Lacks calibration modes or explanations for settings, leading to some confusion among users.
Limited frame rate options; users request additional options like 24fps and 60fps for better accuracy.
Some users find the flashing white screen unpleasant and the app interface or instructions unclear, causing confusion about how measurements are done.
No automatic resynchronization feature; the app only identifies delay but doesn't fix sync issues.

I was looking for an app that can sync the audio with the visual of my video. It seems like this app doesn't allow you to upload a video to do that. So I'm still on my own search. but it let's you take a video and idk maybe records the audio and visual components to get info out of it? Still not sure exactly
