Stereo Tool Preset Fixed May 2026

Stereo Tool’s “Fixed” preset locks the stereo image and processing behavior to a predictable, consistent setting — ideal when you need reliable, unchanging stereo output across tracks or broadcasts.

Thimeo recently introduced the "Auto-tuning" wizard in Stereo Tool 10.0+. This is the digital equivalent of a "stereo tool preset fixed" button. The wizard analyzes 30 seconds of your audio (speech, music, or mixed) and automatically adjusts:

While not perfect, the auto-tune is the fastest way to fix a broken preset you downloaded from a random blog.

A “fixed” preset in Stereo Tool means the processing parameters (EQ, multiband compression, limiting, clipping, AGC, stereo image, etc.) are locked — either by the preset designer, a broadcast engineer, or due to the preset being in a “read-only” or “protected” mode. The user cannot tweak individual sliders unless they unlock or copy the preset. stereo tool preset fixed

These presets are often shipped with the software (e.g., “FM Classic,” “Internet Radio,” “Podcast Clean”) or provided as “set-and-forget” solutions for specific use cases.

“The audio sounds too quiet / too loud compared to other presets.”
Fixed presets don’t compensate for low input levels. Adjust input gain manually.

“It distorts on some songs but not others.”
Fixed presets can’t reduce gain dynamically. Lower the drive or clipper threshold. Stereo Tool’s “Fixed” preset locks the stereo image

“I saved a preset but it’s still changing over time.”
You likely saved an adaptive preset as “fixed” in name only. Double-check that all adaptive modules (especially AGC, Auto EQ, and Loudness) are truly off.

| Advantage | Explanation | |-----------|-------------| | Predictability | Output is deterministic, crucial for regulatory compliance (e.g., FM deviation limits). | | Low CPU overhead | No continuous parameter calculations or external control threads. | | Stability | No risk of parameter runaway from buggy external automation. | | Ease of recall | One file → exact same sound across systems. | | Debugging | Easier to reproduce audio artifacts. |

The clipper is where the loudness war is won or lost. While not perfect, the auto-tune is the fastest

Stereo Tool allows you to cut bass frequencies below a certain point from the side channel (making bass mono to avoid vinyl skipping or FM distortion).

Navigate to the Multiband tab. Look at the crossover frequencies (e.g., Band 1: 40-150Hz, Band 2: 150-400Hz). Fix: If you hear "booming" or "honking," shift these frequencies slightly. For modern music, ensure band 1 doesn't exceed 120Hz.
