Audiolyze vs Continuo

Transform your iPhone or iPad into a professional audio analysis workstation. Audiolyze delivers real-time spectrum analysis, waterfall spectrograms, and oscilloscope visualization with the precision tools you need for sound engineering, acoustic analysis, and audio production. SPECTRUM ANALYZER Visualize audio frequencies in real-time with a high-resolution FFT spectrum analyzer. Choose from multiple display modes (dB, Amplitude, Power) and trace styles (smooth spline curves, linear, or classic bars). Switch between logarithmic and linear frequency scales, and select from multiple constant-Q resolutions for RTA analysis, from 1 octave down to 1/24 octave precision. WATERFALL SPECTROGRAM Track how your audio evolves over time with a scrolling 2D spectrogram display. Capture up to 20 seconds of frequency history to identify temporal patterns, transients, and spectral changes that a standard analyzer would miss. OSCILLOSCOPE Examine waveforms in the time domain with a responsive oscilloscope view. Multiple trigger modes (rising edge, falling edge, auto, free-run) help you capture stable waveforms, with adjustable amplitude scaling and trigger threshold controls. HARMONIC ANALYSIS Automatically detect and display harmonics with intelligent fundamental frequency tracking. View overtone relationships, cent deviations, and harmonic order labels overlaid directly on the spectrum — valuable for tuning, voicing, and timbre analysis. SPL REFERENCE LEVELS View relative sound pressure level readings with a built-in SPL meter. Calibrate against an external reference meter to align readings, with optional Z-weighting (flat response) or A-weighting (human hearing curve). Provided for reference and comparison; not a substitute for a certified, type-approved sound level meter. ADVANCED SIGNAL PROCESSING - Multiple FFT sizes (512 to 4096 samples) - Selectable window functions: Hann, Blackman-Harris, Flat-Top - Configurable frame overlap (0-75%) for improved averaging - Rolling window and exponential smoothing modes - High-pass and low-pass filters with adjustable slopes (6/12/18 dB per octave) CUSTOMIZE YOUR WORKFLOW - Peak hold display with decay - Snapshot comparison for before/after analysis - Visual glow effects for enhanced readability - Sparse or dense grid overlays - Save and recall custom presets for each visualization mode FOR SOUND ENGINEERS & MUSICIANS Whether you're a sound engineer tuning a PA system, a musician analyzing instrument tone, a podcaster optimizing room acoustics, or an audio enthusiast exploring the science of sound, Audiolyze provides the analytical depth you need in a beautiful, intuitive interface. EVERYTHING UNLOCKED Every feature is available from the moment you launch. No subscriptions, no in-app purchases, no paywalls, and no ads. Works on iPhone and iPad. Optimized for performance with GPU-accelerated Metal rendering. Available in 13 languages.

Type the changes. Get the bassline. Most bassline tools ask you for a scale. Continuo asks for your chords. Type a progression — slash chords and all — pick a style, and Continuo writes a line that actually plays those changes: chord tones on the strong beats, approach notes into the next chord, and a register that sits where a bass player would sit. HOW IT WORKS • Type your changes one bar at a time, separated by | — or start from one of 18 built-in sets: 12-bar blues, rhythm changes, ii-V-I, doo-wop, montuno vamp, bossa turnaround, 7/8 vamp and more. • Slash chords like Am/C pin the bass note, so the line plays exactly what you wrote. • Pick a style, then shape it: Density (sparse to busy), Motion (plain roots to passing and chromatic tones), and Swing (straight to triplet). • Tap Next take to cycle through ranked alternatives, best first. Tap any chord in the strip to swap, move, or stretch it — the line rewrites around your edit. • Undo steps back over anything that changed the line — an edit, a preset, an import, a take, even a slider. WHAT'S INSIDE • Seven styles: root and fifth, walking, funk/R&B, tumbao, bossa nova, reggae one-drop, and Motown. • Seven instruments that change what gets played, not just the tone: 4-, 5- and 6-string bass guitar, upright, 808/sub, synth bass, and chiptune. • Any time signature — 4/4, 3/4, 6/8, 9/8, 12/8, 5/4, 7/8, 5/8, 11/8 and more. Every style works in every meter. • Import changes from a MIDI or MusicXML file. • MIDI export, optionally with a reference chord track — plus MusicXML with chord symbols for MuseScore, Sibelius, Dorico, and Finale. • A bass-clef notation preview with chord symbols. • Fully offline. No account, no sign-in, no ads, no in-app purchases. • Private by design — Continuo collects nothing. Your music never leaves your device unless you export it. Continuo is by Songdeed. Pairs with Mediant, our chord-progression app.
