Harmonize your melodies with a single click with vielklang’s intelligent arranger tools.

Create beautiful background choirs
or brass ensembles with Vielklang

vielklang version 2.5 now supports native Apple Silicon (M1/M2) and Windows 11. For this final version, a lot of development work went into making it more performant and robust.

Packed with music theory and intelligent arranger tools, vielklang does the heavy lifting for you and turns single voice vocal recordings into lush four-part harmonies with a single click. The key aware arranger lets you create backing vocals that fit perfectly with your music and will take your arrangements way beyond mere parallel voicings. Simply select the number of voices and try out different harmony settings until you’re satisfied. Play around with the intuitive voice settings until you get the sound you’re after.

vielklang is based on zplane`s advanced pitch & time correction technology, the same technology incorporated in most leading DAWs and used by creators all over the world.

vielklang also works great on instrumental recordings, like creating complete brass arrangement from a single trumpet recording. You can use vielklang`s intelligent arranger tools to harmonize MIDI notes instead of audio.

The full version of vielklang adds even more power, including advanced editing of pitch, timing, vibrato, formant shift and much more.
