Script bash fleksibel: pilih mode, warna, dan resolusi
Kamu bisa memilih mode spectrum (equalizer) atau waveform (gelombang), terus set resolusi dan warna sesuai kebutuhan konten.
Script: audio_visualizer.sh
#!/bin/bash
# Script untuk membuat video visualisasi audio (spectrum/waveform) dari semua file .mp3 di folder
# Output: file video .mp4 dengan nama sama seperti file audio
