# Sound Latency Test

> Compare an acoustic speaker-to-microphone round trip or inspect browser-reported audio timing estimates.

Sound Latency Test helps investigate audio delay with two separately labelled methods. Acoustic mode plays a short chirp and detects its return through a microphone. Browser-reported mode shows available processing and output estimates without a microphone.

Users can label an audio path, save comparison A, compare a second setup, and export numerical results as CSV. Acoustic results include the output, air path and input capture, so a consistent physical setup matters when comparing devices.

Musicians, streamers and listeners comparing audio paths under consistent conditions.

Acoustic round-trip timing does not isolate Bluetooth codec latency or one-way output delay.
