Celemony Software GmbH is a German musical software company that specializes in digital audio pitch correction software. It produces Melodyne, a popular audio pitch modification tool similar to Auto-Tune, although the program itself is manual tuning software.

Celemony was founded in October 2000 by Peter Neubäcker, Prof. Dr. Hildegard Sourgens and Carsten Gehle. It is based in Munich, Germany.

In 2009, Melodyne won an MIPA Award for Most innovative product. In 2011, Celemony released Capstan, a stand-alone audio restoration software that eliminates wow and flutter from digital recordings.

In October 2011, Celemony and PreSonus introduced Audio Random Access (ARA), an extension for audio plug-in formats like AU and VST that permits to exchange data between them which is supported by several DAWs. It is now under an open source license and they also released a comprehensive software development kit (SDK).

Celemony received a Special Merit/Technical Grammy Award at the 54th Grammy Awards in February 2012 for "contributions of outstanding technical significance to the recording field."

Three years before Celemony was founded, Peter Neubäcker was working on a research experiment with sound. This experiment later turned into the Melodyne pitch correction product.

Melodyne has become a tool which is used by a large number of professional record producers worldwide to tune and manipulate audio signals, typically a singer's vocals.^{[citation needed]}

Melodyne also has facilities for time-stretching and rebuilding melodies. It can also be used to aid the creation of backing vocals from an existing lead vocal. The first public viewing of Melodyne was at the Winter NAMM Show in 2001, and it has since won various awards.
