Recorded a conversation on two separate recorders? Their clocks drift, they started at different times, and one might be phase-flipped. BiBimBot aligns them to the sample — automatically, across the whole recording.
Mix my tracks free →We'll align the first 5 minutes free, so you can hear it lock into sync before doing the whole thing.
This was just the first 5 minutes. BiBimBot aligns full multi-hour sessions — drift, dropouts, and all.
See full-length plans →No timecode, no clapboard, no manual nudging. BiBimBot listens to what the microphones share and rebuilds a single timeline.
Two mono files from any two recorders. Mic 1 is your reference; Mic 2 gets aligned onto it.
BiBimBot measures the delay between the tracks across the whole file — start offset, clock drift, even mid-recording jumps.
Mic 2 is gently resampled onto Mic 1's clock and polarity-matched, so the two tracks sum cleanly with no comb-filtering.
Most "sync" tools apply one constant offset and call it done — which drifts apart minutes later. BiBimBot models how the delay changes over time.
Phase-transform cross-correlation locks onto the shared room sound — robust to bleed, reverb, and noise — down to a fraction of a sample.
Two consumer recorders can slip ~1.7 seconds over an hour. We estimate the sampling-rate offset and resample it away — continuously.
If a recorder hiccups mid-session, BiBimBot follows the delay through the gap instead of throwing the rest of the file out of sync.
Detects a flipped track and frequency-dependent phase differences, so summing the two mics reinforces instead of cancels.
Full-length alignment for episodes and back-catalogs is in private beta. Drop your email and we'll get you in — and you'll keep the free sample tool forever.
