Spectrum Analyzer
Semantic type: SpectrumAnalyzer · Category: analyzer
Passes audio through while the host-side EffeTune app can display its frequency spectrum.
Use the opt-in decoded telemetry callback or subscription API to observe this analyzer. See Compatibility.

Spectrum Analyzer
Creates a real-time visual display of your music’s frequencies, from deep bass to high treble. It’s like seeing the individual ingredients that make up the complete sound of your music.
Visualization Guide
- Left side shows bass frequencies (drums, bass guitar)
- Middle shows main frequencies (vocals, guitars, piano)
- Right side shows high frequencies (cymbals, sparkle, air)
- Higher peaks mean stronger presence of those frequencies
- Darker green line shows the current sound
- Brighter green line briefly holds recent peaks, so you can see strong sounds that just passed
- Watch how different instruments create different patterns
What You Can See
- Bass Drops: Big movements on the left
- Vocal Melodies: Activity in the middle
- Crisp Highs: Sparkles on the right
- Full Mix: How all frequencies work together
Parameters
- DB Range - How sensitive the display is (-144dB to -48dB)
- Lower numbers: See more subtle details
- Higher numbers: Focus on the main sounds
- Points - How finely the display separates nearby frequencies (256 to 16384)
- Higher numbers: More frequency detail, with slower updates
- Lower numbers: Quicker updates, with less frequency detail
- The analyzer uses the average of the left and right channels. Mono input is analyzed directly.
