Free browser tools for Bluetooth audio work. Everything runs on your own device: nothing you play, tap or drop into these tools is recorded or uploaded.
Run a Bluetooth latency test in your browser: tap along with a beat and get your end-to-end audio delay in milliseconds. Free, no upload, no app.
Read Latency Tester →70V amplifier calculator: sum speaker taps in your browser, check the load against the 80 percent practice and read impedance on 70.7V or 100V lines.
Interactive toolCheck audio bitrate, codec and sample rate of any file in your browser. Nothing uploaded. Compare with Bluetooth codec ceilings from 127 to 990 kb/s.
Interactive toolSpeaker ohm calculator: combine series, parallel or series-parallel speaker loads in your browser and check each result against a 4 ohm floor.
Interactive toolSpeaker wire gauge calculator: enter run length and speaker impedance for a recommended AWG from ASTM B258 resistance data, computed in your browser.
