Problem
The guitar track sounds static and lacks the dynamic movement typical of funk music.
How to Use
Upload the guitar_riff.mp3 file, select 'Auto-Wah' mode, set wah frequency to 2 Hz, wah depth to 0.9, and mix to 0.7 for a balanced effect.
Example Config
{"mode": "auto", "wahFreq": 2, "wahDepth": 0.9, "mix": 0.7}
Outcome
