ROLAVIScan vs CreamAudio Analyzer

ROLAVIScan is a professional field application for GNSS surveying, RTK positioning, LiDAR scanning, augmented reality, terrestrial photogrammetry and geospatial project management on iPhone and iPad. Built for surveyors, engineers, construction professionals, geodesists and field teams, ROLAVIScan brings capture, stakeout, measurement, reconstruction and visualization tools into one mobile workflow. GNSS AND RTK • Connect supported ROLAVI, SparkPNT TX2, DataGNSS NANO RTK and UM980 Bluetooth receivers • Use NTRIP corrections for RTK positioning • Connect external NMEA sources through TCP • Use iPhone GPS as an approximate SINGLE-position source • View solution status, satellites used and visible, skyplot, signal bars, HDOP, VDOP, correction age and accuracy • Record raw GNSS data with supported ROLAVI receivers SURVEYING • Capture survey points with names, codes and instrument height • Perform point stakeout and review distances and direction • Apply geoid models and Grid Shift corrections • Import and export CSV survey data • Display DXF, KML, KMZ, SHP ZIP and WMS layers • Work with LandXML terrain surfaces and georeferenced raster data • Organize survey points, photos, point clouds and exports by project LIDAR AND POINT CLOUDS • Capture color point clouds and mesh data on compatible LiDAR devices • Preview, process and manage field scans • Export professional point-cloud and 3D formats for further processing AUGMENTED REALITY • Visualize and stake out georeferenced points in AR • Measure AR points, polylines and polygons • Place ROLAVIAR models • Create and inspect AR pipelines and AR polygons • Use shared GNSS/AR calibration for geospatial visualization PHOTOGRAMMETRY AND 3D • Capture georeferenced photo sets • Process on-device photogrammetry projects • Preview and export reconstructed models, including USDZ workflows • Generate georeferenced 3D Gaussian Splatting projects • Export Gaussian models and colored LAS point clouds ROLAVISCAN PRO ROLAVIScan Pro is a single auto-renewable subscription that unlocks the complete compatible workflow, including supported non-ROLAVI Bluetooth receivers, iPhone GPS, TCP NMEA, Surveying, AR, Camera–LiDAR, Photogrammetry and 3D Gaussian Splatting. Monthly and annual plans are available. The subscription title, duration, included services and localized price are displayed before purchase. Payment is charged to your Apple Account after confirmation. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period. You can manage or cancel your subscription in Apple Account settings. Restore Purchases is available inside the app. Some functions require compatible GNSS hardware, a LiDAR-equipped Apple device, internet access for NTRIP or sufficient device storage and processing capacity.

CreamAudio turns your Mac, iPad, or iPhone plus a class-compliant USB or Thunderbolt audio interface (such as a Focusrite Scarlett 2i2) into a complete professional audio measurement bench. The interface's analog inputs become the front end; its outputs drive the built-in signal generator. Multiple precision instruments share one calibrated signal path: OSCILLOSCOPE • Live two-channel display in normal (Y-t) and XY (Lissajous) modes • Adjustable volts/division and time/division with pinch and scroll zoom • Edge triggering with Auto / Normal / Single modes and single-shot capture • Graticule with division labels and live Vpp, RMS, frequency readouts • Per-channel DC/AC coupling and vertical offset FUNCTION GENERATOR • Sine, square, triangle, sawtooth, white and pink noise • Per-channel frequency, amplitude, offset, phase, and duty cycle • Sweep, chirp, and burst programs • Test Tape: an automated alignment-tape sequence (reference tones 400 Hz to 12.5 kHz, sweep, chirp, burst, flutter tone) to record onto a deck and measure back • Route to the same interface (loopback) or a separate output device SPECTRUM & SPECTROGRAM • Real-time FFT spectrum with selectable size and windowing, log/linear axes • Spectrogram heatmap across the recorded timeline FREQUENCY RESPONSE • Measure response with white / pink / swept stimulus that drives the generator automatically; curves accumulate for easy comparison DISTORTION & LEVEL • Automatic THD, THD+N, and SNR measurement • Vpp, Vrms, mean, frequency, period, and duty-cycle readouts • Built-in analog-style AC millivoltmeter (1 mV to 30 V, dual volt/dB scales) WOW & FLUTTER METER • Speed-stability analysis for turntables, cassette, and reel-to-reel tape • DIN / IEC 386 (3150 Hz) and JIS (3000 Hz) reference tones with auto-detect • WRMS, DIN 2-sigma quasi-peak, and unweighted readings; deviation waveform RECORD, SCRUB & EXPORT • Record the raw two-channel stream and scrub the timeline to find transients • Re-run any analysis offline on a selected window • Save recordings to WAV (lossless) or AAC (.m4a) CALIBRATION • Map normalized samples to real volts with manual entry or a guided reference solve, so every reading is in true voltage units; profiles persist per device Sample rates up to 192 kHz where the interface supports them. Everything runs locally on your device — no account, no network, no data collection. Requires a Metal-capable device. An external audio interface is recommended for real measurement work; the built-in microphone can be used for casual signals. Requires a subscription or one-time purchase. Start with a 3-day free trial, after which a monthly subscription begins automatically and renews each month unless cancelled at least 24 hours before the period ends. Prefer to pay once? Unlock everything with a one-time lifetime purchase — no trial, no subscription. The free trial is available to new subscribers. Subscription and lifetime prices are shown in the app and on this product page. All features described below are included once unlocked; there is no separately-priced content.
