DepthCapture｜LiDAR Point Cloud vs Biquadia

DepthCapture records RGB and depth on iPhone/iPad. View RGB, depth maps and 3D point clouds live for measurement and research. ―――――――――― ■ Depth sources Sources depend on your device: ・LiDAR ・LiDAR+Spatial ・TrueDepth ・Stereo Depth ・AI Depth LiDAR uses the rear sensor, TrueDepth the front camera. Stereo requires a compatible camera. LiDAR+Spatial requires a supported LiDAR device and adds camera position/orientation in local capture space. AI Depth estimates relative depth from images; matching LiDAR or TrueDepth distance accuracy is not guaranteed. ―――――――――― ■ Record RGB + Depth Snapshot Capture saves RGB, Depth and capture info; Stream Recording saves continuous RGB-D. RGB: ・JPEG ・PNG Depth: ・BIN ・16-bit PNG ・TIFF ・EXR ―――――――――― ■ Live depth preview View RGB and Depth live with color maps: ・Grayscale ・Blue-Red ・Viridis ・Inferno Use an automatic or fixed depth range to check data and adjust subjects or settings. ―――――――――― ■ Live 3D point clouds View live 3D point clouds from depth and camera info, colored by RGB or depth. ―――――――――― ■ Object detection Detect selected categories, such as people, cars or animals. Overlay regions on RGB; highlight or show only points in those regions. Enable during capture to save results for in-app review and export as PNG masks + JSON info. Detection display does not alter saved RGB/Depth or exported point clouds. Detection may fail or skip recording frames depending on conditions and processing load. ―――――――――― ■ Export point clouds Export saved Snapshots or Stream Recording frames: ・PLY ・GLB ・glTF ・PCD ・LAS ・CSV ・E57 ・XYZ ・XYZRGB XYZ: coordinates only. XYZRGB: coordinates + saved RGB colors. E57 supports only saved LiDAR/LiDAR+Spatial data with the required depth/camera information. LiDAR+Spatial aligns only frames with valid poses in one coordinate system. Use with 3D software, point-cloud tools or Python. ―――――――――― ■ Continuous RGB-D recording Set saving intervals for Stream Recording. Save as RGB/Depth file sequences or ROS2-compatible MCAP, which can include RGB, Depth, CameraInfo, TF and IMU / Device Motion for robotics or computer vision. ―――――――――― ■ Capture metadata Settings and camera info, when available: ・Camera Intrinsics ・Extrinsic Matrix ・Lens Distortion ・Camera pose/tracking status (LiDAR+Spatial) ・RGB / Depth resolution ・Depth Source ・Depth Accuracy / Quality ・Depth Filtering ・Capture settings Snapshots and recordings include manifests and metadata for checking capture conditions on Mac/PC. ―――――――――― ■ Capture settings Settings vary by source/device: ・Depth Filtering ・Depth FPS ・Depth Resolution ・RGB Resolution ・RGB / Depth Synchronization ・Depth Range ・Save Depth Preview Balance quality, processing load and file size. Use built-in presets or save, reuse and share your own. Saving or importing custom presets requires a feature unlock purchase. ―――――――――― ■ Sync multiple devices Bluetooth syncs Snapshot capture and Stream Recording start/stop operations. Only operation timing is synced: set capture settings per device; image acquisition times may differ. ―――――――――― ■ Review saved data Saved Data shows Snapshot RGB, Depth and 3D Point Cloud, and lets you scrub/play Stream Recording frames. Share sessions or access them in Files. ―――――――――― ■ Uses ・LiDAR/depth-sensor checks ・3D point-cloud capture/viewing ・RGB-D collection ・Computer vision ・Machine-learning datasets ・Robotics/ROS2 ・AR/3D sensing: capture/validation ・Research/experiments/prototyping ・Depth-source comparison/testing Sources, resolutions and frame rates vary by device/camera. Without LiDAR, supported TrueDepth, Stereo Depth or AI Depth may be available. Advanced features can be unlocked by a one-time purchase or an auto-renewing monthly plan. The monthly plan includes ad removal. Watch rewarded ads for temporary feature access. ―――――――――― Terms of Use (Apple Standard EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Biquadia is an acoustic engineering and audio analysis lab designed for audio engineers, researchers, and sound designers. It brings real-time DSP, acoustic measurement, spectral visualization, and spatial analysis directly to iOS and iPadOS. [IN-APP PURCHASE DISCLOSURE] Biquadia includes powerful core features completely free of charge. Advanced features marked below with [Requires In-App Purchase] require a Biquadia Pro subscription (Monthly with a 7-day free trial) or a Lifetime Purchase. FREE FEATURES INCLUDED: • DSP Lab: Real-time FIR/IIR filtering, parametric EQ, dynamics processing, live oscilloscope, and FFT spectrum analyzer. • Analysis Lab: High-resolution FFT, pitch tracking, formant estimation, and real-time STFT spectrogram. • Measurement Lab: Multi-sweep acoustic measurements, impulse response capture, and calibrated SPL analysis. • Psychoacoustics & Codec Lab: Codec difference spectrograms, perceptual masking thresholds, and Bark/Mel scale overlays. • Audio FX & Signal Generator: Sine, frequency sweeps, pink/white noise generator, plus chorus, drive, and delay visualization. • System & Audio Hub: System performance diagnostics, multi-channel I/O mixer, and live signal routing meters. PRO FEATURES [REQUIRES IN-APP PURCHASE]: • Target-Speaker Extraction [Requires In-App Purchase]: Experimental on-device Core ML model that isolates one enrolled voice from a mixture using its speaker embedding — a technology demonstration, not a general-purpose noise remover. • Advanced Array Processing [Requires In-App Purchase]: Covariance-based MVDR beamforming for multi-microphone arrays (up to 32 channels). • Ambisonics & Spatial Audio [Requires In-App Purchase]: First-Order Ambisonics (FOA) encoding, 3D scene rotation, and binaural room impulse response decoding. • Measurement Data Export [Requires In-App Purchase]: CSV export of per-band THD+N/SNR measurement data. IN-APP PURCHASE OPTIONS: - Biquadia Pro Monthly: $4.99/month (Auto-renewable subscription with a 7-day free trial). - Biquadia Pro Lifetime: $79.99 (One-time non-consumable purchase). Biquadia processes audio entirely on-device. It has no developer-operated backend, telemetry, or audio upload. Network activity is limited strictly to Apple StoreKit and user-selected external links.
