Read full description

Concept: The app is a pitch monitoring tool and works as standalone or AUv3 plugin. It will analyze an incoming audio signal using FFT and display its spectral graph in real-time (unit: musical pitch not hertz). The user can watch and study in detail the pitch distribution of audio source. Usage: There are seven sliders. 1. Resolution: determines the analysis resolution. (higher resolution - worse time response) vice versa 2. Pan: works as panner, only if input source is stereo. 3. Magnify: magnifies the screen horizontally. 4. Slide: slides the screen horizontally. 5. Out: determines the audio output to be turned on or off (default: Off). 6. Input: input gain in dB. 7. Tuning: adjusts A4’s reference frequency in the range from 414hz to 467hz (default: 440). In the app the pitches are represented as follows: C -> C Cis -> 1 D -> D Es -> 3 E -> E F -> F Fis -> 6 G -> G As -> 8 A -> A B -> B H -> H Specifications: Compatible with the following sampling rate (from 44.1khz to 96khz)

About

A deep four-oscillator drone synthesizer for meditation, sound healing, and ambient composition. Inspired by Pauline Oliveros, Éliane Radigue, Stars of the Lid, William Basinski, and the long-form drone tradition. Real synthesis, real tuning systems, real cymatics — designed for listeners who want to go deep. Most "drone apps" give you a few sliders and call it ambient. Drone Meditations gives you a real instrument. SOUNDS YOU CAN SIT WITH FOR HOURS • Four oscillators per patch — sine, triangle, sawtooth, square, white / pink noise, granular pink, or loaded sample • Per-voice filter (LP / HP / BP), drive, cross-osc FM, stereo chorus, three-mode delay with musical timing, stereo Schroeder reverb • Twenty multi-target LFOs per patch (five per voice). LFOs 1–4 hit amp / pan / cutoff / Q / pitch / FM / FX-Mix; LFO 5 has its own row of granular + FX targets (grain, delay, reverb). Each LFO's rate can lock to a musical subdivision of the tempo. • Per-voice timing envelopes — fade in over minutes, fade out later, repeat N times or forever. Rotate harmonically across 20 minutes without touching a slider. • Six tuning systems: 12-TET, just intonation, Pythagorean, Lou Harrison Free JI, Wendy Carlos α/β/γ, Harry Partch 43-tone DESIGNED FOR THE DRONE TRADITION • 110+ presets across Drone Artists, Developer Patches, Solfeggio, Natural Resonance, Cymatics, Mystic & Composers, and Binaural categories — plus an INIT preset pinned at the top • 48 Drone Artists tributes — Oliveros, Riley, Radigue, Stars of the Lid, Sunn O))), Basinski, Niblock, Palestine, Budd, Coltrane, and more — capturing each artist's waveforms, FX, and tuning, not just their pitches • 21 Developer Patches showcasing granular sampling, BPM-locked grain density, FX-Mix LFO swells, and the JG hybrid pad/groove series • Modal chord category — the 7 diatonic modes plus Harmonic and Melodic Minor — with quantize-to-scale so pitch-modulated voices arpeggiate across all 7 mode degrees • Auto-morph between any two presets over 30 s to 60 min • 25 scripted meditation journeys (Deep Listening, Heavy Resonance, Minimalist Arc, and 22 more) • Tune to Room — global LISTEN snaps the chord root to a pitch from the mic; per-strip ear icon snaps just one voice LIVE CYMATICS THAT BREATHE WITH THE AUDIO • Physically-calibrated Chladni patterns fit from real plate- vibration footage. The renderer crossfades between two adjacent eigenmodes bracketing each voice's live frequency — vibrato breathes between physical modes, not styled animation. • Pinch to zoom; tap to enter fullscreen Performance mode with a drifting sand-particle simulation along the nodal lines • Cymatic snapshot gallery + spectrum-analyzer alternative GRANULAR + TEMPO • Granular waveform: pink noise chopped into Hann-windowed grains with size, density, jitter, stereo spread, per-voice overlap • Granular sampling: same scheduler on any loaded sample — freeze a bansuri forever, smear a chord into a tape-decay cloud • BPM-quantized density (½ → 1/32T) locks grain spacing to the global tempo. Per-LFO rate sync extends musical subdivisions to LFO speed. Metronome click toggle for an audible reference. RECORD, SHARE, AND COMPOSE • Mastered session recording: 24-bit WAV + AAC M4A sidecar with loudness normalization, automatic fades, embedded metadata • Per-voice mic record captures into a voice's sample slot — normalized, granular-ready, with the current frequency as the sample's reference pitch • 50+ bundled samples: bansuri, organ, piano, storm, tide, forest, urban, cosmic • Cross-device preset sharing via .dronepreset files — AirDrop a patch between web, iPhone, and iPad, samples embedded inline. iCloud auto-syncs samples-free presets across devices. One-time purchase. No subscription, no accounts, no tracking. Free web version: dronemeditations.com

Verdict

The call

The clearest difference is price: pitchGraf at $2.99 against Drone Meditations's $14.99. pitchGraf also leads on iOS requirement (15.0 vs 17.0). Drone Meditations's advantage is update cadence (every 3 weeks vs every 7 months). On ads, in-app purchases and device support there is nothing between them.
