OVNI Audio Releases Telescope - Free Open-Source Audio Analyser for macOS and Windows (VST3 & AU)

The thirteenth lens, Verdict, runs 21 deterministic rules over a per-second history and writes each finding with the measured number and the rule that produced it. The plug-in writes nothing to the audio: 0 samples of latency, bit-exact pass-through.

The useful part

The thirteenth lens, Verdict, runs 21 deterministic rules over a per-second history and writes each finding with the measured number and the rule that produced it. The plug-in writes nothing to the audio: 0 samples of latency, bit-exact pass-through. Telescope ships as one signed and notarized installer with VST3 and AU, universal, for macOS 11 or later.

Details worth keeping

OVNI Audio makes free, open-source plug-ins in three families: spatial effects that move sound and open up space, Supernova — a visual synth that turns sound into image — and Telescope, an analyser that measures a mix and writes down what it found. Telescope puts thirteen lenses over one analysis engine: loudness to ITU-R BS.1770 with LRA and true peak, dynamics, spectrum, spectrogram and waterfall, constant-Q with a key estimate, stereo scope and per-band correlation, energy by pan direction (not localisation), and tonal balance against a reference file.
