Groove Number vs EchoSketch

how swung is your track? groove number gives you the number. drop in a song, record a clip, or open the live mic — groove number listens and tells you the one thing drum machines flatten and great players bend: the groove. 50% is dead straight. ~66% is full triplet swing. most music that feels good lives in between, around 54–62%. now you can see it. and it's not just the number. what it reads • swing % — the hero. one honest number for how far off the straight grid the groove sits. • bpm — dual-estimator with an octave guard, so 174 never gets called 87. nudge it ×2 / ÷2 or tap the tempo to lock it, and the swing recomputes against the corrected grid. • key — chroma + krumhansl-schmuckler with a tuning estimate, shown with a confidence read and the runner-up key, so a close call never hides. four ways to see it • meter — the number, front and center: swing %, bpm, and key in one calm readout. • swing grid — the signature view. every onset plotted against the straight 8th/16th grid, colored on-time, late, or rushing. you can see the pocket. • spectrogram — mel-scaled heatmap, quiet to loud, low to high, with a frequency + dB scale. • chromagram — the 12 pitch classes over time, tonic marked. how it listens • a file you drop in or pick (mp3, m4a, aac, wav, aiff, flac) • a clip you record — it listens and stops on its own the moment the groove locks • the live mic — a running bpm + swing read in the room, with a VU level meter and a live spectrogram one more thing • groove → midi — export the groove as a midi clip, swing baked into the note timing. drop it on a drum track in any daw and it plays your pocket. built to be calm and honest • fully on-device. your audio is analyzed right on your iphone, ipad, or mac. nothing is uploaded. nothing is stored on a server. • no account. no sign-up. no ads. no tracking. • strongest on four-on-the-floor and electronic music. live, acoustic, and rubato material is harder — so groove number always shows its confidence and hands you the ×2/÷2 and tap-tempo overrides. wrong calls stay visible, never silent. one number for the feel of a track. plus everything you need to trust it.

EchoSketch turns delay and reverb into a live, playable instrument. Shape your sound in real time using a responsive X/Y performance surface designed for intuitive touch expression. At its core are four great-sounding delays: digital, analog, ping-pong, and reverse. The range for each parameter and the XY axes direction can be set independently, allowing you to easily morph between sounds. It works as an Audio Unit plugin or standalone — iOS or Mac. Comprehensive Delays • Digital (patterned after a legendary '80s rack delay), Analog (warm, with tape-style pitch glide), Reverse, and Left/Right Ping-Pong • Delay times can sync to tempo or be set in milliseconds • Feedback features delay-dependent tone shaping — bright for short delays and darker for long ones Convolution Reverb • Stereo or mono Spring, Plate, and Hall • Reverb path is separate from the delay (same as vintage tape echo units), so repeats don’t get washed out Modulation and Filter • Analog-style modulation for chorused, warbly pitch echoes • Tone control — darken or brighten delays, with a center detent for flat Designed for Hands-On Performance • HOLD / LIFT — leave the XY cursor in place, or touch the pad for momentary delay sounds • FREEZE — set the current feedback into an infinite loop and play over it • MOTION — record a gesture on the XY pad and loop it Presets and More • Presets are transferable between hosts • Two looks — light "Trail" and dark "Glow" • Works standalone with live audio or as an AUv3 plugin • Universal — iPad/iPhone also gets you the Mac version — one purchase • Mac: after installing, open EchoSketch once to use it as a plugin in your DAW • Works in AUM, AudioBus, GarageBand, Logic, and other AUv3 hosts
