Stereo Tool by Thimeo is a professional-grade audio processor used for FM, AM, and web broadcasting. It allows for extensive customization of sound through various processing modules and non-audio configuration settings. Core Audio Processing Settings stereo tool settings

These settings control the "signature sound" of your broadcast by managing dynamics and frequency response:

Input Gain: Adjusts the level for left and right channels before processing begins.

Automatic Gain Control (AGC): Evens out the sound to prevent listeners from needing to adjust their volume.

Multiband Compressor: Compresses specific frequency bands to achieve a consistent "big sound".

Stereo Separation: Increases or decreases the width of the stereo image. "Stereo Tool" is a professional broadcast audio processor

Advanced Clipper: Provides clipping without distortion to maximize loudness within legal limits.

Bass & Highs: Tools like Power Bass, True Bass, and Bass Boost add depth to tracks with poor low-end response. FM & RDS Text Settings

Optimizing Your Audio with Stereo Tool Settings

Stereo Tool is a powerful audio processing plugin used in broadcasting, live events, and music production to enhance and manipulate stereo audio signals. With its comprehensive set of tools, Stereo Tool allows engineers and producers to adjust, correct, and creatively manipulate the stereo image of their audio. Understanding and optimizing Stereo Tool settings can significantly impact the quality and character of your audio output. Use "Voice" preset as a base

7.3 For Podcasting

  • Use "Voice" preset as a base.
  • Lower the multiband release times to 300-500 ms for a natural sound.
  • Disable stereo widening (most podcasts are consumed in mono via earbuds).

Recipe B: Transparent & Wide (Classical / Jazz / Audiophile)

  • AGC: Target -12 dB, Slow (2000ms release)
  • Multiband: 3-Band, "Smooth" preset. Reduce all band gains to 50%.
  • Loudness: Drive at 30%. No Bass/Treble boosts.
  • Clipper: Hardness 60%, Strength 2% (just catching true peaks).
  • Result: Preserves dynamic range and stereo width. Low loudness (-16 LUFS).

4.3 The "Band Pass" Filter (A hidden gem)

  • Setting: Each band has a high-pass and low-pass crossover.
  • Default: 40-150, 150-400, 400-2000, 2000-12000.
  • Custom trick: Widen the mid band (400-4000 Hz) for more vocal presence.

Stereo Tool Settings: How to Get Cleaner, More Consistent Audio from Your Stereo Tracks

Whether you’re a mixing engineer, producer, or hobbyist finishing a stereo buss or multitrack mix, having the right stereo tool settings can dramatically improve clarity, width, and punch. This post walks through practical, actionable stereo-processing techniques—EQ, compression, mid/side, saturation, imaging, and limiting—with concrete starting settings and how to adjust them for different goals.

6.3 Clipper Threshold & Ceiling

  • Threshold: -6 dB to -3 dB (How early the clipper engages).
  • Ceiling: -0.5 dBFS (Absolute maximum).
  • Pro tip: Enable "Pre-Clipper EQ" to gently roll off highs before clipping. This reduces harsh "crackling" artifacts.

Problem: "The highs are sibilant and harsh."

  • Solution: Go to the Clipper section and enable "High Frequency Limiting" at 8 kHz with a strength of 20%. Also, reduce Coupling from the high band to the mid band.

Stereo Image Control

  1. Image Width: Adjusts the stereo image from mono to wider than stereo. Be cautious with extreme settings, as they can lead to an unstable image on mono playback.

  2. Image Center: Allows for shifting the center of your stereo image. Useful for making your mix sound more balanced or for creative purposes.

6) Limiting / Final Peak Control

Purpose: catch peaks and raise overall level before mastering, without squashing dynamics.

Typical limiter chain:

  • Gentle bus limiter with ceiling −0.3 to −0.1 dB.
  • Aim for 1–4 dB of gain reduction on mix bus in loud genres; 0–2 dB for dynamic genres.
  • Use lookahead sparingly; slower release preserves punch.

How to check:

  • Listen for pumping, distortion, or stereo imbalance introduced by limiting.
  • Prefer leaving more headroom for mastering if submitting to an external mastering engineer (−6 to −8 dB RMS headroom; peaks below −6 dBFS).
