Chroma is a visualization plug-in designed to reveal the musical notes within any audio track. By analyzing the sound, it provides a clear graphical representation of the notes present, making it easier for users to identify chords and assist in transcription tasks. This tool is particularly useful for musicians and producers who want to gain deeper insight into the harmonic content of their recordings.

The plug-in processes audio based on the equal-tempered scale, classifying each frequency into its corresponding musical note or intermediate pitch. The resulting chromagram displays bright horizontal lines that indicate the presence and strength of specific notes. The intensity of these lines reflects the volume of each note, offering a continuous view that extends beyond the traditional 12-tone scale, allowing for nuanced pitch detection.

Ideal for analyzing single tracks or full mixes, Chroma enhances the workflow of anyone working with musical audio by providing a detailed, real-time visual breakdown of pitch content. Its continuous pitch representation and clear display simplify the process of chord identification and transcription, making it a valuable addition to any music production or analysis setup.
