Klangmanipulation is a German freeware audio software project focused on VST instruments, effects, and SynthEdit modules. The developer publishes plugins for Windows that lean toward synthesis and sequencing tools, with a community-oriented approach centered on free downloads and SynthEdit DSP module sharing.

Notable releases include the SynchroNator, a two-oscillator software synth featuring Moog-style low-pass and high-pass filters, tempo-syncable LFOs, and an 8-step sequencer, with per-oscillator volume, pan, fat, pulse-width, semitone, and octave controls. Other titles distributed through outlets like Plugin Boutique include the Synchronizer synth and the MIQU 2.0 sequencer. The project also maintains a presence on the SynthEdit Users Forum, where it contributes DSP modules used by other SynthEdit-based plugin builders.

Klangmanipulation has 3 products cataloged on Equipboard, including Synth Plugins and Sequencer Plugins.
