"We tried solving acoustic quality control with software on off-the-shelf hardware. It wasn't enough - dropped packets and clock drift got in the way. Lab-grade mics solve that, but they're built for far more than any ML pipeline needs. So we built the microphone we wished existed: synchronized, high-throughput, consistent unit to unit. Now we're offering it to every ML engineer who needs the same.”

Why the MPK801

Three things that make acquisition easy

Three things that make acquisition easy

Swap a microphone in minutes.

Calibration data lives on each microphone and is applied automatically, so a replacement drops straight in. No recalibration, no model retraining.

No room for calibration error.

Every microphone carries its own calibration data. There is no separate file to match to a serial number and nothing to configure by hand.

Know the moment something stops.

Heartbeat monitoring flags a microphone that stops reporting, and packet-loss tracking verifies every recording is complete. Nobody has to check by hand whether data is still arriving.
