StageTracker Mobile vs OmniRTA

MULTI-TRACK AUDIO StageTracker – The All-in-One Live Performance App StageTracker turns your iPhone, iPad, or Mac into a powerful stage companion. Manage your entire show from one place: songs, setlists, lyrics, backing tracks, video clips, MIDI, and click – all perfectly synchronized. AUDIO PLAYBACK Load multiple audio tracks per song with independent volume, pan, and effects. Route audio to different output channels with professional multi-channel interfaces like the RME Babyface Pro FS. Adjust pitch and speed in real time without compromising quality. VIDEO & HDMI OUTPUT Add video clips to your songs and send them to an external screen via HDMI. Use idle screens (image or video) between songs for a polished stage look. Video playback stays perfectly in sync with your audio and click tracks. LYRICS & TELEPROMPTER Write, edit, and display lyrics with automatic scrolling during playback. Zoom controls let you adjust text size for any stage situation. Use play mode as a full-screen teleprompter – on your device or on an external display. MIDI TRACKS & TRIGGER Create MIDI event sequences to control external gear – lighting desks, synths, effects processors, or anything that speaks MIDI. Trigger MIDI events at precise moments during your songs. CLICK TRACK Built-in click track engine with configurable time signatures, count-in bars, and accent patterns. Keep your band tight without needing a separate click source. SETLISTS Organize songs into setlists with drag-and-drop reordering. Auto-advance to the next song when playback ends. Queue songs manually or let the setlist flow automatically through your entire show. DEVICE SYNC Connect multiple devices on stage via local network. Sync lyrics, setlist position, and transport controls across iPads and iPhones so every band member stays on the same page. SONG SHARING Export and import songs as .stgsong files – including all audio, video, MIDI, and lyrics. Share via AirDrop, email, or any file sharing method. Full backup and restore for your entire library. WORKS EVERYWHERE Designed for iPhone, iPad, and Mac (Catalyst). Adaptive layout adjusts automatically to your screen size. Runs natively on Apple Silicon. FREE & PRO Get started for free with up to 3 songs and core features. Upgrade to StageTracker Pro for unlimited songs, multi-channel routing, and the full feature set. Whether you're a solo artist, worship leader, or full band – StageTracker keeps your show running smoothly from first note to final bow.

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.
