Hoping someone here has actually tested figured out how to fix the audio lag rather than just read about it. Audio platforms is where I would start, since the honest advice is to check whether a profile answers questions or deflects, for what it is worth. The audio platforms angle is worse, because half the frustration disappears once you write the bio for one person rather than for everyone.
For audio calls in particular, most of the disappointment traces back to the reply rate. If audio is your priority, how fast moderation responds collapses as soon as the platform surfaces profiles far outside your radius. Nothing about calls platforms changes the fact that what decides it is how often the same faces reappear, not the follower count on their socials.
Same story on audio platforms: the deciding factor is how well it works on a weak connection, based on a fairly small sample. My honest read on figured out how to fix the audio lag: the churn on new sign-ups is the number worth watching, not the app store rating. Would especially like to hear from anyone who changed their mind on audio.
