…zation Fixes devlup-labs#1 - Added Bar3DVisualization with perspective projection - X-axis: frequencies, Y-axis: amplitudes, Z-axis: time variation - 3D box rendering with 6-face shading (top brighter, bottom darker) - Auto-rotation + interactive mouse drag rotation - Scroll zoom support - History buffer (deque) for time-series FFT data - New vertexShader3D.glsl with mat4 MVP uniform - Added option 5 in main.cpp menu - Depth testing enabled for proper 3D occlusion
…iables Fixes devlup-labs#2 - Added AudioVariables struct with bass, mid, treble + EMA smoothed versions - Added extractBands() method in AudioProcessor - Frequency ranges: Bass 20-250Hz, Mid 250-4kHz, Treble 4k-20kHz - EMA smoothing (decay=0.1) for bassAtt, midAtt, trebleAtt - Added getAudioVariables() getter - getFFTData() now also extracts band variables

Fix for Issue #2
Problem
The audio processing pipeline computes FFT data but does not extract distinct frequency bands (Bass, Mid, Treble) or their attenuated versions using EMA smoothing.
Solution
Added
AudioVariablesstruct andextractBands()method toAudioProcessor:bassAtt,midAtt,trebleAtt) using exponential moving average with decay factor 0.1getFFTData()now also extracts band variables; accessible viagetAudioVariables()Changes
src/Audio.h: AddedAudioVariablesstruct,getAudioVariables()getter,extractBands()method,emaDecaymembersrc/Audio.cpp: ImplementedextractBands()with frequency band separation and EMA smoothing; updatedgetFFTData()to call itVerification
