You can play the sound from any source, like Spotify, WinAmp, CD/DVD player, or use mic-in connector. With AudioInput component, you can get real-time waveform data samples from sound device. NET (WPF and WinForms), you may find it useful. LightningChart SDK is set of components for Visual Studio. We have lately added DirectSound-based audio data input routines in LightningChart data visualization library. It's all up to your imagination what to do with them.Р”Вisplay a picture, multiply the size by the bass for example - you'll get a picture that'll zoom in on the beat, etc. Once you have some values for for example bass, midtones, treble and volume(left and right), If you want to read about beat/tempo-detection google for Masataka Goto, he's written some interesting papers about it. (Paul Bourke is a name you want to google anyway, he has a lot of information about topics you either want to know right now or probably in the next 2 years ))

If you're accustomed to math you might want to read Paul Bourke's page :

More interesting and responsive visualizers can be written that combine the frequency-domain information with an awareness of 'spikes' in the audio that often correspond to percussion hits.Р”Р‡or creating BeatHarness ( ) I've 'simply' used an FFT to get the audiospectrum, then use some filtering and edge / onset-detectors. One characteristic of frequency-component-based visualizers is that they don't often seem to respond to the 'beats' of music (like percussion hits, for example) very well.

In the early days (and still), visualizers often modified the color palette in Windows directly to achieve some pretty cool effects.

Generally, the graphics methods have to be extremely fast and lightweight in order to update the visuals in time with the music (and not bog down the PC). How the visual display is updated in response to the frequency info is up to the programmer.

The visualizer does a Fourier transform on each slice, extracting the frequency components, and updates the visual display using the frequency information. As a visualizer plays a song file, it reads the audio data in very short time slices (usually less than 20 milliseconds).
