Instant Harmony with vielklang

Get complete harmonization with voice leading on one single click - loading a single-voiced audio file - and create natural-sounding background choirs and brass arrangements!

It's all about Music

vielklang "thinks musically" and prepares the ground. vielklang is packed with musical intelligence and music theory: it automatically detects the best fitting harmoniesfor each individual input melody, and automatically synthesizes up to four voices with the voices not merely running in parallel but with their voicings automatically selected to sound most natural (voice leading). vielklang gives you a natural-sounding result immediately and allows you to concentrate on tweaking the results rather than edit them from scratch as with traditional harmonizers.

Creativity First

Directly interact with the music rather than with the technology. Don't waste time with tedious configuration of obvious parameters like root note, scale, tuning frequency etc.; let vielklang take care of this with its automatic recognition engines and concentrate on making music! Have complete control over your voicings and musical parameters like harmonies, pitch range and scale.

Discover the Potential

The vielklang audio harmonization instrument is not a harmonizer, but much more! With the vielklang plugin, you can easily generate and trial natural sounding background vocals and brass sections, modify melodies and single-voiced loops in terms of pitch and scale, and experiment with different harmonizations or chords triggered by different MIDI inputs. It allows you to generate up to four voices, edit their harmonies and single pitches, control the playback speed, and convert the audio to MIDI.
