XPZE App vs OmniRTA

XPZE analyses vocal audio to estimate how a voice is being processed. By examining pitch behavior, variation, and vocal characteristics, XPZE provides insight into whether vocals appear natural, lightly processed, heavily pitch-corrected, or synthetic. XPZE is designed for music fans, creators, producers, journalists, and broadcasters interested in understanding how modern vocals are shaped. Results are estimates and for educational and entertainment purposes only. For best results, scan clear vocals (verse + chorus ~30 seconds).

OmniRTA is an advanced real-time acoustic analyzer engineered for audio professionals, sound design students, musicians, and acousticians. Combining high-performance DSP with a clear, pedagogical interface, OmniRTA bridges the gap between signal theory and practical sound analysis. A Unique Educational & Comparative Platform: Unlike traditional RTAs limited to a single processing method, OmniRTA integrates multiple frequency analysis engines, allowing you to compare signal behaviors side by side and understand how different algorithms handle transient vs. steady-state audio: Standard Direct FFT: High-speed frequency decomposition optimized for real-time responsiveness, wideband signals, and general monitoring. Constant-Q / Fractional Octave Filterbank: Acoustically relevant octave and fractional-octave banding (1/1, 1/3, 1/6, 1/12, 1/24 octave) that matches human auditory perception across the audible spectrum. Proprietary Low-Frequency Transient Engine (Exclusive): Traditional FFT algorithms suffer from a strict time-frequency uncertainty trade-off, either sacrificing time accuracy or frequency resolution in the low end. OmniRTA introduces an innovative analysis engine specifically designed for low-frequency transient and percussive content. Accurately track fast double-kick drums, heavy techno sub-bass patterns, and low-end impact dynamics with surgical frequency definition and zero temporal smearing. Key Features: • Real-time multi-algorithm spectrum visualization. • Standard acoustic weightings: A, C, and Z (Flat). • Response ballistics: Fast, Slow, Peak Hold, and Infinite Peak. • Native high-performance DSP core written in Rust for minimal latency and optimal battery efficiency. • Seamless cross-platform experience across iOS, iPadOS, and macOS. Free vs Pro Version: OmniRTA offers essential spectrum analysis features for everyday work and learning. Upgrade to OmniRTA Pro via a one-time in-app purchase to unlock advanced fractional octave bands, deep algorithm customization, and extended logging tools.
