So i've been looking into the java sound api and I can get input,record and play back sounds and i can draw a graph using coordinates or sin. I want to be able to have a live "Oscilloscope" as such which takes input from the mic and converts it into a waveform which scrolls left over time and when a noise is made the sound (frequency?) is added on to the left …

https://github.com/goxr3plus/Java-Audio-Wave-Spectrum-API
Java-Audio-Wave-Spectrum-API. Create Wave Spectrum from any Audio File using this API , written in JavaFX. How this works ? We convert the given audio if not to .wav using Jave2 library. We get the .wav amplitudes in a beautiful smart way. Based on the given width of the canvas we draw the wave. On every change of width re-calculate the wave and redraw.
