Direct Note Access (DNA)

Melodyne’s DNA Direct Note Access is the technology that allows one to identify and edit individual notes in the polyphonic material. This system offers unique access to the pitch, duration, timing, and other parameters of notes in the monophonic material.

Direct Note Access: How It Works

To begin with, DNA Direct Note Access can modify the operation of audio. In the digital image processing universe, the right software cannot only correct reality down to the smallest details; it can also help create new worlds. For instance, these new world consists of images that describe with total credibility something that has never existed. Because of this, DNA provides total freedom in the audio field. Melodyne with DNA Direct Note Access allows the user to intervene with audio material in unimaginable ways, from subtle enhancements to re-composition.


In brief, Melodyne is the main software developed by Celemony using Direct Note Access. Since the beginning, this software offered new possibilities regarding the quality of its pitch and time manipulation engine caused a real sense of excitement amongst musicians. The software has progressed through several stand‑alone versions that have widely improved throughout the years. Similarly, the plug‑in version proved itself indispensable for many everyday audio‑buffing tasks.

DNA Direct Note Access and Its Algorithms

It includes three processing algorithms: first, the pre-existing Melodic and Percussive settings; second, the Note Assignment mode; third and last the new DNA-powered Polyphonic mode. The algorithms aren’t perfect, so it’s essential that the software’s note detection matches the sound being produced. If this doesn’t happen, the processing won’t work as it should. Users can control the way Melodyne interprets the pitches in the audio with a special Note Assignment mode.

The Detection Process

The detection process is more complex and time consuming for polyphonic material. In order to operate accurately, Melodyne needs a precise map of all the notes in a given chord. If it detects only one note in a two-note chord, and the user tries to shift the pitch, both pitches will end up shifting. Although Melodyne is great at the polyphonic detection process, some time spent in Note Assignment mode is quite helpful too. Also, because users tend to lose information every time they enter the Note Assignment mode, it’s a better idea to deal with detection problems straight away.
