Loudness Equalizer

A specialized equalizer that automatically adjusts frequency balance based on your listening volume. This plugin compensates for the human ear’s reduced sensitivity to low and high frequencies at lower volumes, ensuring a consistent and enjoyable listening experience regardless of playback level.

Listening Enhancement Guide

Low Volume Listening:
- Enhances bass and treble frequencies
- Maintains musical balance at quiet levels
- Compensates for human hearing characteristics
Volume-Dependent Processing:
- More enhancement at lower volumes
- Gradual reduction of processing as volume increases
- Natural sound at higher listening levels
Frequency Balance:
- Low shelf for bass enhancement (100-300Hz)
- High shelf for treble enhancement (3-6kHz)
- Smooth transition between frequency ranges

Parameters

Average SPL - Current listening level (60dB to 85dB)
- Lower values: More enhancement
- Higher values: Less enhancement
- Represents typical listening volume
Low Frequency Controls
- Frequency: Bass enhancement center (100Hz to 300Hz)
- Gain: Maximum bass boost (0dB to 15dB)
- Q: Shape of bass enhancement (0.5 to 1.0)
High Frequency Controls
- Frequency: Treble enhancement center (3kHz to 6kHz)
- Gain: Maximum treble boost (0dB to 15dB)
- Q: Shape of treble enhancement (0.5 to 1.0)

Tone Control

A simple three-band sound adjuster for quick and easy sound personalization. Perfect for basic sound shaping without getting too technical.

Music Enhancement Guide

Classical Music:
- Light treble boost for more detail in strings
- Gentle bass boost for fuller orchestra sound
- Neutral mids for natural sound
Rock/Pop Music:
- Moderate bass boost for more impact
- Slight mid reduction for clearer sound
- Treble boost for crisp cymbals and details
Jazz Music:
- Warm bass for fuller sound
- Clear mids for instrument detail
- Gentle treble for cymbal sparkle
Electronic Music:
- Strong bass for deep impact
- Reduced mids for cleaner sound
- Enhanced treble for crisp details

Parameters

Bass - Controls the low sounds (-24dB to +24dB)
- Increase for more powerful bass
- Decrease for lighter, cleaner sound
- Affects the “weight” of the music
Mid - Controls the main body of sound (-24dB to +24dB)
- Increase for more prominent vocals/instruments
- Decrease for more spacious sound
- Affects the “fullness” of the music
Treble - Controls the high sounds (-24dB to +24dB)
- Increase for more sparkle and detail
- Decrease for smoother, softer sound
- Affects the “brightness” of the music

5Band PEQ

A professional-grade parametric equalizer based on scientific principles, offering five fully configurable bands with precise frequency control. Perfect for both subtle sound refinement and corrective audio processing.

Sound Enhancement Guide

Vocal and Instrument Clarity:
- Use 3.2kHz band with moderate Q (1.0-2.0) for natural presence
- Apply narrow Q (4.0-8.0) cuts to remove resonances
- Add gentle air with 10kHz high shelf (+2 to +4dB)
Bass Quality Control:
- Shape fundamentals with 100Hz peaking filter
- Remove room resonance using narrow Q at specific frequencies
- Create smooth bass extension with low shelf
Scientific Sound Adjustment:
- Target specific frequencies with precision
- Use analyzers to identify problem areas
- Apply measured corrections with minimal phase impact

Technical Parameters

Precision-Engineered Bands
- Band 1: 100Hz (Sub & Bass Control)
- Band 2: 316Hz (Lower Midrange Definition)
- Band 3: 1.0kHz (Midrange Presence)

Narrow Range

A tool that lets you focus on specific parts of the music by filtering out unwanted frequencies. Useful for creating special sound effects or removing unwanted sounds.

Listening Enhancement Guide

Create unique sound effects:
- “Telephone voice” effect
- “Old radio” sound
- “Underwater” effect
Focus on specific instruments:
- Isolate bass frequencies
- Focus on vocal range
- Highlight specific instruments
Remove unwanted sounds:
- Reduce low-frequency rumble
- Cut excessive high-frequency hiss
- Focus on the most important parts of the music
