摘要： Systems and methods for generating a visual color display of audio-file data are provided. The system includes a processor that performs a method including receiving audio-file data; generating filtered-audio data by processing the audio-file data by frequency-band filters. The frequency band filters have different frequency bands. The method includes generating one or more waveforms corresponding to the filtered-audio data and displaying the waveforms superimposed in unique color relative to one another. The method includes downsampling the waveforms. The method includes processing the waveforms through an envelope detector. The method includes processing the waveforms through an expander and applying a gain factor. The waveforms have transparency levels at sections that are proportional or inversely proportional to amplitudes at the sections.

摘要： Systems and methods for musical tempo detection are provided. The method includes detecting peaks and their locations in a waveform of a digital audio track, and dividing the track into first measures with a first-measure length based on a first estimated tempo. The method includes determining distances between a beginning of the first measures and each peak location, and determining a first number of peaks having the same distance from the beginning of the first measures. The method includes dividing the track into second measures with a second-measure length based on a second estimated tempo; determining distances between a beginning of the second measures and each peak location; and determining a second number of peaks having the same distance from the beginning of each of the second measures. The method includes estimating an accurate tempo by comparing the first number of peaks and the second number of peaks.
