SoundManager2 has irregular latency
- by Stefan Monov
I'm playing some notes at regular intervals. Each one is delayed by a random number of milliseconds, creating a jarring irregular effect. How do I fix it?
Note: I'm OK with some latency, just as long as it's consistent.
Answers of the type "implement your own small SoundManager2 replacement, optimized for timing-sensitive playback" are OK, if you know how to do that :) but I'm trying to avoid rewriting my whole app in flash for now.
For an example of app with zero audible latency see the flash-based ToneMatrix.
