Experience with delay #146

Closed smxthereisonlyone closed 4 years ago

We'd like to put audio triggers into a video stream and then detect those on iOS & Android to synchronize. Is that possible and with what delay?

AddictedCS commented 4 years ago

What kind of triggers? Acoustic triggers of type "a specific audio signal in a specific frequency range", or just any regular audio content?

smxthereisonlyone commented 4 years ago

We'd do 20 minutes of video stream with 20 minutes of audio. The video starts and goes for a few minutes. Now, imagine a user opens an app that includes sound fingerprinting, then sound fingerprinting starts and we'd like to know the exact timecode of the video. Is that possible?

This is achievable.
