Loopeme is a pocket loop studio for musicians who write on the move. Hear a groove in your head? Tap the tempo, hit record, lay down a phrase. Loopeme auto-trims the silence, snaps the take to the bar and stacks it on top of the previous layers. The idea that used to die in your voice memos turns into a track instead. Built on a real C++ DSP engine: tracking and mixing run at low latency, and WAV export prints the same effect chain you played live — what you hear is what you keep. CATCH THE IDEA • Tap Tempo — set BPM from your own pulse, no "type 124" panel • Auto-trim — strips silence around your take at a dB threshold you control • Cut Mode — drag loop boundaries on the waveform and hear the result instantly • Metronome with pre-roll and downbeat accent BUILD THE TRACK • Multi-layer loop stack — pile takes on top of each other, each with its own fader and effects • Rhythm generator — turn one phrase into a pattern: ×2, ×4, ×8, ×16, triplets, backbeat, off-beats • Pitch Shifter and Peak Filter on every track • Add Bar / Remove Bar — change loop length on the fly, no re-record PLAY FROM ANYWHERE • Apple Watch — full remote: record, play, tap tempo from your wrist while the iPhone sits on the stand • MIDI controllers (BETA) — map Play / Stop / Rec / Tap to notes or CC, play with a footswitch or pad • iCloud — projects sync across all your devices TAKE IT OUT • WAV export of the whole project through the full FX chain — ready for your DAW • Inline previews in the project list before you open a session FOR WHO Guitarists, producers, beatmakers, looping vocalists, music teachers and anyone whose best idea happens in line for coffee instead of in the studio. Loopeme doesn't try to replace your DAW — it catches the stuff that never makes it there. We'd love your feedback — reach us from the in-app settings.

A classic algorithmic reverb effect based on the Freeverb algorithm by Jezar at Dreampoint. A Freeverb-style Schroeder/Moorer reverb based on the classic 8-comb + 4-allpass topology, with simplified controls and no stereo spread. This reverb creates lush, spacious ambience through a network of comb and allpass filters. Freeverb is widely used in electronic music production, ambient music, and sound design to add depth, space, and atmosphere to audio sources. The algorithm provides a smooth, musical reverb tail that works well on everything from vocals to synthesizers. This reverb only functions in mono and provides no stereo imaging, and the user can expect the same behavior as a classic Freeverb implementation otherwise.
