Start with your media
Record camera video with a live visualization, import audio or video from Files, or choose media through the Photos picker.
Local-first audio and video workspace
See sound in context. Keep media local.
Record or import audio and video, explore spectra and spectrograms, arrange visual overlays, organize projects, and export media or traceable reports—all without an account. Free app surfaces and exports include the AcoustoViz watermark, and overlay-video exports support up to 30 seconds. Pro unlocks the professional template library, multiple simultaneous controls, full-length export, no ads, and automatic watermark removal; the brand mark can be shown again in Settings.
Multiple views, one timeline
Inspect waveform, FFT spectrum, spectrogram, octave bands, markers, selections, and playback from a coordinated local workspace.
Projects that keep context
Use search, tags, favorites, archives, templates, sessions, and recoverable jobs while preserving the settings behind each result.
Media and traceable reports
Create rendered media plus CSV, JSON Lines, PNG, and PDF outputs with units, configuration, hashes, and limitations.
Measurement boundary
Levels are relative dBFS by default. Optional user calibration can produce derived dB SPL only while its input route, format, channel policy, evidence, and validity period still match. AcoustoViz is not an IEC 61672 Class 1/2 certified sound-level meter, legal metrology, medical advice, or a safety/compliance decision.
Media stays local
No account, cloud dependency, or automatic media upload. Recordings and projects stay on device until you export or share them. The free tier may show consent-gated Google banners on Projects and Settings; app media is never sent to the advertising SDK.
