5Band Dynamic EQ
Semantic type: FiveBandDynamicEQ · Category: eq
Applies level-dependent equalization in five configurable bands.
This type has catalog telemetry metadata but no public observation API in v0.1. See Compatibility.
Contract
- Seeded: no
- Catalog sample rates: not declared; this does not mean unsupported
- Assets: none
- Catalog-declared latency: zero
- Telemetry: catalog metadata only; observation API unavailable in v0.1

5Band Dynamic EQ
A smart equalizer that automatically adjusts frequency bands based on the content of your music. It combines precise equalization with dynamic processing that responds to changes in your music in real-time, creating an enhanced listening experience without constant manual adjustments.
Listening Enhancement Guide
- Tame Harsh Vocals:
- Use peak filter at 3000Hz with higher ratio (4.0-10.0)
- Set moderate threshold (-24dB) and fast attack (10ms)
- Automatically reduces harshness only when vocals get too aggressive
- Enhance Clarity and Brilliance:
- Use Band 5 with Filter Type: Highshelf, Frequency: around 10000Hz, SC Freq: around 1200Hz, Ratio: 0.5, Attack: 1ms
- Mids trigger high frequencies for natural-sounding clarity
- Adds sparkle to music without permanent brightness
- Control Excessive Bass:
- Use lowshelf filter at 100Hz with moderate ratio (2.0-4.0)
- Keep bass impact while preventing speaker distortion
- Perfect for bass-heavy music on smaller speakers
- Adaptive Sound Tailoring:
- Lets music dynamics control the sound balance
- Automatically adjusts to different songs and recordings
- Maintains consistent sound quality across your playlist
Parameters
- Five Band Controls - Each with independent settings
- Band 1: 100Hz (Bass Region)
- Band 2: 300Hz (Lower Midrange)
- Band 3: 1000Hz (Midrange)
- Band 4: 3000Hz (Upper Midrange)
- Band 5: 10000Hz (High Frequencies)
- Band Settings
- Filter Type: Choose between Peak, Lowshelf, or Highshelf
- Frequency: Fine-tune center/corner frequency (20Hz-20kHz)
- Q: Control bandwidth/sharpness (0.1-10.0)
- Max Gain: Set maximum gain adjustment (0-24dB)
- Threshold: Set level when processing begins (-60dB to 0dB)
- Ratio: Control processing intensity (0.1-100.0)
- Below 1.0: Expander (enhances when signal exceeds threshold)
- Above 1.0: Compressor (reduces when signal exceeds threshold)
- Knee Width: Smooth transition around threshold (0-10dB)
- Attack: How quickly processing begins (0.1-100ms)
- Release: How quickly processing ends (1-1000ms)
- Sidechain Frequency: Detection frequency (20Hz-20kHz)
- Sidechain Q: Detection bandwidth (0.1-10.0)
