Parseval is a multi-microphone audio measurement platform for sound-system tuning and room acoustics, built for techs who work with several measurement mics at once. It competes on trustworthiness rather than feature count: a published accuracy specification, reproducible results, and coherence-weighted displays that visibly de-emphasize untrustworthy data instead of drawing a confident line through it.
Features
- Multi-mic transfer function measurement — up to 8 concurrent dual-FFT engines from one shared reference
- Phase-preserving (complex) smoothing with magnitude-squared coherence, blanking low-confidence regions rather than faking them
- Multi-time-window analysis for constant fractional-octave resolution, plus fixed-window modes
- Per-engine delay finding via cross-correlation, reported in ms, samples, and temperature-corrected distance
- Correct spatial averaging that separates coherent and incoherent math and refuses to average unaligned positions
- Clock-domain awareness: cross-clock measurements are detected and flagged as wrong, not silently resampled
- Signal generator, RTA / spectrograph, SPL metering with logging, and impulse-response / ISO 3382 room metrics
