Potentially useful for the surface level experience of music, there are established programs and systems to visualize music in terms of Frequency, Amplitude, and other elements through microphone input. While this may not convey the in-depth information of a score, this technology can be an easy and often portable way to offer a visualization of “surface level” sonic events in music both in a recorded setting and in live performance. Many applications and website-based spectrum analyzers are available on mobile devices as well as desktop computers, providing options for students studying at home or attending live performances.
When provided to supplement a score, this can be a great way for students to better visualize the musical events. However, without a score, this can also prove useful for beginning music students or students taking general education music courses to familiarize themselves with the density and events within the act of listening to music.
Microphone Sound Analyzer is a free online sound spectrum analyzer that uses your device’s microphone to provide a visual spectrum analysis with regards to frequency and amplitude. Since this analysis is performed in real time, the contours for frequency and amplitude move rhythmically in relation to the musical events as they occur. This allows for a relative facsimile of experiencing the sonic events in real time, with representations of density, pitch, and dynamic.
The application can be run from a desktop computer with a microphone to pic up audio played by the same computer or another device.
