Bass & Treble

Adjust warmth and brightness with two shelves.

Both adjustments combine. Current defaults of 500 Hz and 1500 Hz include more speech than the original 120 Hz / 6000 Hz tuning.

01 / Understand

The idea, before the settings.

Two separate shelves shape the low and high ends. Bass and Treble each have their own gain and transition frequency; this is not one movable peaking band.

SourceBass & TrebleMeter → Output

Use it in AudioRouter

  1. Begin with Bass and Treble at 0 dB so the shelves are flat.
  2. For boom, try Bass −3 dB and move Bass frequency lower to focus on the bottom rather than all low mids.
  3. For brightness, try Treble +2 dB. Raise Treble frequency to affect mainly the upper end.
  4. Match output loudness before comparing Bypass; check headroom after boosts.

What success looks like

Shelves change broad regions. Frequency moves the transition; it is not a separate gain adjustment.

If it does not work

If voice sounds thin or harsh, reduce the amount or move the transition away from important voice frequencies.

Select the node to open Properties. Click its name to rename it. While playing, supported parameter-only edits save after a short pause. For structural edits, use Save when the canvas marks a change. Enabled and Bypass are distinct live controls; see the in-app help for their behavior.

02 / Explore

Make the behavior visible.

The fixture combines bass, bell harmonics and broadband texture. Listen for low weight versus high brightness, rather than overall loudness alone.

The example repeats until you press Stop, and control changes are heard immediately. The picture shows the tool's shape rather than time; follow the timing in Follow the sound below. This is not a DSP measurement or control for your running AudioRouter session.

03 / Configure

Every control, with a reason.

↓ Lower / alternativeCuts low frequencies.

↑ Higher / alternativeBoosts low frequencies.

Try thisTry −3 dB to reduce excess warmth.

Keep in mind Its frequency changes how much speech is affected.

↑ Higher / alternativeBoosts brightness.

Try thisTry +2 dB for a modest lift.

Keep in mind Boost may also emphasize hiss and consonants.

↓ Lower / alternativeKeeps the adjustment lower in the spectrum.

↑ Higher / alternativeIncludes more of the voice in the bass adjustment.

Try thisTry 120 Hz for a focused low-bass change; 500 Hz reaches more of the low-mid warmth.

Keep in mind A frequency change can make the same dB value sound stronger.

04

Treble frequency

Boundary of the treble shelf transition.

Range / choices800 Hz → 12000 HzDefault1500 Hz

↓ Lower / alternativeIncludes more speech in the treble adjustment.

↑ Higher / alternativeKeeps the adjustment in higher frequencies.

Try thisTry 6000 Hz to change the high end while leaving more voice presence intact.

Keep in mind Runtime frequency eligibility depends on sample rate.

04 / Put it to work

Start with a useful example.

Example 1

Reduce a boomy microphone

  1. Try Bass −3 dB at 500 Hz.
  2. Keep Treble at 0 dB while evaluating.
  3. Compare bypass at a matched listening level.
Example 2

Focus on the frequency extremes

  1. Set Bass frequency to 120 Hz and Treble frequency to 6000 Hz.
  2. Keep your chosen gain amounts and compare the narrower regions affected.

These are starting points. Compare at a comfortable monitoring level and adjust for your own source.

05 / Get unstuck

Small details that matter.

  • Large boosts can consume headroom.
  • Changing a frequency can make the same gain setting sound much stronger.
