Abstract
Methods, systems, and media for performing visualized quantitative vibrato analysis are provided. In some embodiments, a method for analyzing musical vibrato in an audio file is provided, the method comprising: receiving, using a hardware processor, a target note from a user; receiving, using the hardware processor, a time-domain signal representing a piece of music comprising a plurality of notes, wherein the plurality of notes include the target note and the target note is played with a vibrato effect; converting, using the hardware processor, the time-domain signal to a frequency-domain signal; determining, using the hardware processor, a plurality of changes in frequency and intensity of the vibrato effect over time based on the frequency-domain signal; determining, using the hardware processor, a target frequency corresponding to the target note; and displaying, on a display, data about the changes in frequency and intensity of the vibrato effect over time and data about the target frequency.
