Sounn VR Audio Analyzer vs EXPOCAL

Sounn VR turns your iPhone or iPad into a real-time audio analyzer for rooms, speakers, studios, stages, and live spaces. See sound as it happens with live FFT and RTA views, spectrograph history, and a camera-based VR overlay that places spectrum analysis over the space you are checking. Use it for fast setup checks, speaker tests, room comparisons, feedback hunting, education, and repeatable audio workflows in the field. REAL-TIME AUDIO ANALYSIS - Live microphone spectrum analysis from 20 Hz to 20 kHz. - RTA bar, line, and Bar+FFT display modes. - Linear, log, octave, 1/3, 1/6, 1/12, 1/24, and 1/48 octave analysis. - Selectable FFT sizes: 1024, 2048, 4096, and 8192. - Multiple FFT windows including Hann, Hamming, Blackman, Blackman-Harris, Flat Top, and Rectangular. - Peak hold, decay controls, reference snapshots, and difference views. SPECTROGRAPH HISTORY - Watch frequency energy change over time. - Review recent live sound events with an in-memory history. - Use horizontal or vertical spectrograph direction for different workflows. VR AUDIO OVERLAY - View the live spectrum over the camera feed. - Quickly connect what you hear with where you are in the room. - Record walkthroughs with the spectrum overlay and save them to Photos with Sounn Pro. BUILT-IN SIGNAL GENERATOR - Generate sine waves, pink noise, white noise, and swept sine. - Set frequency from 20 Hz to 20 kHz with a log slider and numeric control. - Run generator and analyzer together for loopback-style setup checks. SAVE, COMPARE, AND EXPORT WITH SOUNN PRO - Save and recall analyzer presets. - Compare live measurements against saved references. - Export CSV data, spectrum images, spectrographs, and settings files. - Share results through Files, Photos, Clipboard, Mail, AirDrop, and the iOS Share Sheet. - Back up settings and preset definitions with iCloud. LOCAL BY DESIGN Sounn VR processes audio on your device. Measurements and presets stay local unless you choose to export or back them up. Sounn VR is built for practical visual audio analysis. It is not a certified SPL meter, medical hearing test, or safety dosimeter. Terms of Service: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

EXPOCAL is the on-set exposure companion for cinematographers, DPs, and gaffers — every calculation you reach for between scouting a location and rolling, in one fast, dark-themed app. Nail exposure Incident metering math built on ISO 2720: dial in ISO/EI, shutter angle, and frame rate to get the exact T-stop — or work backwards from an aperture to the lux you need. Handles dual-base sensors and broadcast gain (dB) too. Match your gear Pick from a built-in library of 47 cinema cameras and 241 lenses. Check sensor coverage, mount compatibility, and how a lens, extender, or adapter behaves across your kit. Director's viewfinder Frame a shot right on your phone. Choose a camera and focal length and the live preview matches that lens's field of view — pinch or use the thumb zoom slider to find the frame before the camera is even built. Overlay mode draws the exact framing on a wide preview. Depth & focus Hyperfocal distance, depth of field, and aperture sweeps with sweet-spot, diffraction, and noise guidance. Light & color ND filter stops, white-balance mired shifts, and CTB/CTO/plus-green gel recommendations. Timecode Read SMPTE LTC straight from the audio input and show it full-screen, big enough to hold in front of a lens. When the sound has a clock and the camera does not, you film the number. The reader flywheels through dropouts and says when it has lost lock rather than pretending it hasn't. Export Generate clean PDF reports for scene and sensor planning. EXPOCAL gives estimates to support your judgment on set — always confirm critical exposures with your meter and monitor.
