Description

Introduced by Meyer Sound, M‑Noise is a mathematically derived test signal that that effectively emulates the dynamic characteristics of music. The M-Noise (“Music Noise”) test signal is as a more appropriate signal than the commonly used pink noise signal. Even if a filter, such as the ANSI/CTA-426-B filter, is applied to a pink noise signal to shape its magnitude to more closely match the magnitude of typical music content, the resulting crest factor versus frequency will not match that of typical music like M-Noise will.

In any application requiring reproduction of musical content, M‑Noise enables a far more accurate measurements as well as a more efficient break-in processes compared to other existing methods. At higher frequencies, the crest factor of M-noise represent music much better than any other test signal or pink noise as an example.
