THEPHONOLOOP (also branded as TPL) is a small studio run by a two-person team of music producers and sound designers who build sample-based virtual instruments and sound libraries with a vintage, tape-processed aesthetic. Their catalog is oriented toward composers, producers, and sound designers, and their releases are distributed primarily through their own storefront and through resellers like Plugin Boutique.

Their instruments run inside Native Instruments' Kontakt and Kontakt Player, with additional offerings as Ableton racks. Notable releases include themkI, a deeply sampled recreation of a 1970s electro-mechanical electric piano with MPE support; Tapes.01, a library of noises, textures, and modular/synth sources captured to tape, cassette, and microcassette; outlines, a Kontakt Player instrument built from acoustic gestures, tape loops, and modular experiments aimed at cinematic scoring; and a broader Cassette series that includes mallet, keys, toy piano, vibraphone, and plucked-instrument libraries recorded through cassette machines.

The studio's signature is the deliberate embrace of the imperfections of analog tape media — wow, flutter, hiss, and saturation — layered onto otherwise clean acoustic, electromechanical, or synthesized source material. All content is sold royalty-free for use in commercial and non-commercial productions.

THEPHONOLOOP has 38 products cataloged on Equipboard, including Kontakt Instrument, Instrument Bundles, and Expansion Packs. Most THEPHONOLOOP products sit on the budget-friendly end of the spectrum.
