Efx FRAGMENTS vs OpenVoxTuner

Efx FRAGMENTS is Arturia’s creative audio effect plugin for dividing, transforming, and rebuilding sound with granular processing. Classic, Texture, and Rhythmic modes provide different granular approaches. Pitch quantization offers 15 scales, while grain quantization can follow transient detection or snap to a grid. A spatializer includes nine trajectory presets, and two effect slots provide routing options. The modulation section combines an envelope follower, three function generators, and a step sequencer. A curated library supplies 60 presets. The plugin supports VST, AAX, Audio Unit, and NKS in 64-bit DAWs, with a standalone app also listed. It runs on Windows 10 or later and macOS 11 or later, requiring at least 4 GB RAM, 1 GB free disk space, and a four-core CPU. Apple M1 is supported; Windows ARM processors are not. The listed Efx FRAGMENTS plan costs €79 as a one-time purchase purchase.

OpenVoxTuner is a free real-time vocal pitch correction and harmony-generation plugin for Linux, macOS, and Windows. Its Auto mode quantizes pitch to one of 14 scale types, with adjustable correction speed and amount. Graphic mode provides pitch-curve editing with snapping, a grid, copy and paste, and undo and redo. The harmony engine supports up to four voices, in voice and synthesized modes. Key detection can use audio input, the OpenVoxKey companion bridge, or a sidechain input. Built-in effects include formant processing, reverb, a noise gate, and an upward compressor. ARA2 integration reads key, scale, and time signature from the DAW timeline and syncs the playhead and waveform, but the plugin remains a real-time effect rather than an offline note-level editor. MIDI output can be generated from detected pitch, and MIDI input can control correction pitch. The plugin is free for personal and commercial use under AGPLv3, with source code on GitHub. The maker says it has no telemetry or feature paywalls and directs support questions to GitHub issues and discussions.
