DecibelRTA vs Wavevra

DecibelRTA is an ultra-fast, professional real-time acoustic analyzer combining a fractional-octave IIR spectrum analyzer and an advanced IEC sound level meter on a unified display. Engineered with a native, zero-latency DSP core, DecibelRTA displays 11 vital acoustic metrics simultaneously without requiring navigation through menus: 11 METRICS AT A SINGLE GLANCE • Instant Spectral Pitch: Dominant musical note (e.g. A#2), frequency (Hz), and exact level (dB). • Core Metrology Chips: Leq 5s (equivalent continuous level), ACUM (psychoacoustic sharpness), LRA (Loudness Range dynamic spread), L50 (median ambient level), and CRST (crest factor). • Standard SPL Bar: SLOW (1s), FAST (125ms), and instant PEAK decay monitoring. HIGH-PRECISION SPECTRUM ANALYZER (RTA) • 3, 6, 12, and 24 bands per octave constant-Q filter bank (up to 240 selective IIR bands). • Contextual dual-path engine delivering sharp low-frequency transient tracking below 280 Hz. • Real-time spectral centroid, active -3 dB bandwidth marker, and continuous peak-hold curve. • Linear regression spectral tilt line (beta) for instantaneous noise color identification (pink, white, brown noise). • Built-in industry reference target curves (Flat, Audiofrog, Harman Room, JBL House, B&K Optimum) with a ±3 dB tolerance corridor. IEC 61672 SOUND LEVEL METER & STATISTICS • Type-standard A-weighting with true-RMS exponential ballistics (FAST / SLOW). • Continuous 5-second sliding Leq and sliding statistical histogram (L10, L50, L90). • Dual-mode dynamic range: Studio Mode (30 to 100 dB) and LIVE Mode (50 to 120 dB). • Fast overload CLIP warning and color-coded acoustic safety levels. BUILT FOR SOUND PROFESSIONALS • Live sound engineers & FOH: Quick feedback detection and stage SPL limits. • Studio & Mastering: Mix tonal balance, dynamic compression (LRA), and high-frequency fatigue check (ACUM). • Car Audio & Hi-Fi: In-cabin acoustic calibration and speaker alignment against target curves. • Acoustic & Industrial Hygiene: Noise floor surveys (L90) and OSHA/NIOSH threshold tracking. Microphone access is strictly processed on-device in real-time. No audio data is ever recorded, stored, or transmitted.

See what sound looks like with Wavevra. Wavevra combines real-time audio analysis with expressive audio-reactive visuals and a creator-focused Studio. Explore sound as it happens, record audio or video, import existing media, shape the result, and export videos directly on your iPhone. SEE SOUND IN REAL TIME Watch your audio come to life through Wave, Spectrum, Radial, and Flow visual styles. Wavevra uses real audio analysis to drive its visuals. Explore dominant frequencies, RMS and peak levels in dBFS, headroom, frequency bands, and strong frequency peaks. For a more technical view, switch between Spectrum, Spectrogram, and Waveform. CREATE YOUR LOOK Choose from multiple visual styles and color palettes. Adjust intensity and smoothness to shape the motion and appearance of your visual. Wavevra Pro unlocks additional visual styles, palettes, and creator options. RECORD OR IMPORT Use your microphone for live analysis and recordings. Capture video with your camera or import supported audio and video files already on your device. Imported media is analyzed locally and can be opened directly in Studio. EDIT IN STUDIO Play back your media, move through the timeline, choose the part you want to export, and adjust the presentation. Use layouts including visual-only, split, side-by-side, and overlay compositions. Choose from multiple aspect ratios including: • 9:16 for Shorts and Reels • 16:9 for YouTube and landscape video • 1:1 for square content • 4:5 for portrait content EXPORT AND SHARE Create finished videos from your audio-reactive visuals. Share your exports, save them to Photos, or save them through Files. Wavevra Pro adds longer recording and export options, measurement overlays in exported videos, additional creative options, and removes Wavevra export branding. BUILT FOR PRIVACY Wavevra does not require an account. Your audio, video, analysis data, projects, and exports are processed on your device. Wavevra does not use advertising, tracking, or analytics. FREE TO USE Wavevra remains useful without a subscription. Live analysis, technical analyzer views, local projects, recording, Studio, and core export features are available in Free. Wavevra Pro expands the creative and export capabilities of the app through monthly or yearly subscriptions available through the App Store. Wavevra reports digital audio levels such as dBFS. It is not a calibrated sound level meter and does not report dB SPL.
