Field notes
The bench combines signal generation and measurement in one browser interface, with controls for pink noise, timed bursts, a 20 Hz–20 kHz logarithmic sweep, channel selection, FFT smoothing, and trace freezing. It supports a reference capture from a loopback or calibrated microphone, then offers CSV export and a PDF report containing the graph, settings, and notes. The interface shows a 48.0 kHz engine and a protective limiter at −3 dBFS.
