Rainbow Display

With the Audio Editor set to the Rainbow display, the spectral properties of an audio file are indicated by colors in the waveform.

To open the Rainbow display, click Rainbow at the bottom of the Audio Editor window.

Representing the spectral properties of audio material by multiple colors in the waveform in this way enables you to perform a quick visual analysis of the audio file. Hence, the Rainbow display can serve purposes such as the following:

• In music production and mastering, it allows you to identify patterns, such as the presence of specific timbres, and to locate problematic areas in the audio material; for example, too much bass or too many high frequencies.

• In forensics, it facilitates the identification and subsequent extraction of significant signals, even in extremely noisy recordings.

• In educational contexts, it constitutes a visual aid for explaining and learning about sound structure.

• In linguistics and speech analysis, it provides insight into how different spectral features correlate with phonemes, intonation, and other elements of speech.
