Another new visualization idea ...

Axis	Mapping	Visual Effect
X-Axis	Panning (L-R)	Determined by the ratio of $(L - R) / (L + R)$
Y-Axis	Frequency	High frequencies at the top, low at the bottom
Bubble Size	Amplitude (Energy)	The louder the signal at that specific "pan-frequency" coordinate, the larger the bubble.
Persistence	Time Decay	Old bubbles fade out, leaving a "ghost" of where the energy has been, creating a visible "soundstage shape."

Looks quite interesting ... this is Gemini's version ...

Claude's version buay swee ...

Took Gemini's version and colored it ... it looks colorful & nice ...

 

[boxerfan88]

With logarithmic bin grouping ...

 

[boxerfan88]

After fine tuning the thresholds ...

 

[boxerfan88]

Added gridlines. Reduced NUM_BANDS, adjusted DECAY_RATE and THRESHOLD_* for snappier performance.



If interested, code is posted at HydrogenAudio.

I tried porting it to JSP/SMP platform but the performance is not good, and occasionally can hang foobar2000 due to cpu starvation. I've abandoned the JSP/SMP migration effort. Staying with WebView is much safer because it runs on a process separate from foobar2000. I don't want my eye candy to affect music playback.

Added 2 more algorithms that boost the HF sensitivity so that the bubble sizes and dancing look closer to how it sounds.
These modes are user select-able.




If interested, head over to HydrogenAudio to pick up the code.

• Mode1 = original
• Mode2 = HF boost
• Mode3 = Sum with cap (even more aggressive boost)

When the bubbleMode switch fades away after 2mins, just hover mouse over the bottom right to make it visible again.
