Stereo Tool — Settings

Once you master the basics, these advanced separate the pros from the amateurs.

Located under the "Repair" or "Auto EQ" tabs (depending on your version), these tools are essential for consistency.

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

Before adding loudness or enhancements, you must clean up the incoming audio. Processing distorted or noisy audio only amplifies the flaws. Input Gain

Dynamically changes the compressor behavior based on the specific texture of the incoming song. 3. Stereo Separation and Widening Controls how wide or centered your broadcast sounds. Grid / Spacing: Allows expanding the side channel ( stereo tool settings

Stereo Tool is a professional-grade Swiss Army knife for audio. Whether you are broadcasting to thousands of listeners on FM or just enjoying music on your PC, mastering these settings unlocks a level of control that is rare in consumer software.

Keep compression moderate here to preserve vocal clarity and prevent a "hollow" or nasal sound.

Focus on the (to stop wild volume swings), the Multi-band (to fix muddy mids), and the Clipper (to control loudness). Use the presets as a foundation, but trust your ears.

Corrects tape alignment issues from legacy audio sources. If you notice your stereo image tilting slightly to one side, use this to center it automatically. High-Pass Filter (HPF) Set this between 30 Hz and 40 Hz for general broadcasting. Once you master the basics, these advanced separate

Fixes phase shifts introduced during original recordings or low-quality digitizations. Turn this on to restore high-frequency clarity.

Modern music suffers from the "loudness wars," leaving many tracks distorted and flat. Stereo Tool can digitally repair this damage.

However, with great power comes great complexity. Its overwhelming number of settings is the main reason many users give up on it. Whether you're looking for the "loud and punchy" sound of an FM radio, a clean and natural tone for streaming, or just want to make your music library sound better, this guide will walk you through the most critical settings to help you get the best sound without needing an engineering degree.

The dynamics section is the heart of your signature sound. It controls consistency, punch, and tonal balance. Automatic Gain Control (AGC) Processing distorted or noisy audio only amplifies the flaws

Turn this on to balance volume differences between different songs or speakers.

Cap this at 3.0 dB to keep the stereo widening natural. Too much widening causes listener fatigue and makes the audio sound hollow on mono speakers. 3. Multiband Dynamics (The Core Processor)

Set this just below the clipping point (usually around -0.1 dB to -0.5 dB).

Use Left/Right for standard stereo tracks, or Sum/Difference if you want more control over the stereo field.

5 or 7 bands offer the best balance between precise tonal control and CPU efficiency.
