PRO-301/N Sound Quality 2CH Start-up package

Headset recording & playback and Analysis

PRO-301/N is a 2-channel professional recording system with a playback function which allows listening to your product noise during development, helps to identify sources and checks for improvement through simulation, using filtering and Re-synthesis capabilities.

This ultra-portable headset solution for binaural recording can replace an artificial head in any situations where an individual cannot be taken out, typically for measurement at the driver location in a car while running. Composed of a BMH headphone with integrated microphones and a 24 bits Professional PC-card, PRO-301/N includes the relevant software capabilities enabling you to analyze and optimize the performance of your product:

Playback equalization
Sound Quality Metrics
Advanced Filtering capabilities (option)
RPM and order analysis (option)
Time-frequency edition and signal re-synthesis (option)
