Overview of the Software

Thimeo StereoTool is not merely an audio effect; it is a comprehensive suite of processing tools that acts as a complete audio chain. From the moment audio enters the software to its final output, StereoTool applies a series of algorithms to ensure the sound is loud, clear, and consistent. Originally developed to perfect FM radio signals by eliminating overshoots and optimizing for the “loudness war,” it has evolved into an indispensable tool for any audio professional seeking to deliver a polished listening experience.

The software operates as a standalone application, a VST plugin, or a Winamp DSP plugin, offering unparalleled flexibility. Its primary goal is to maintain a dynamic, natural sound while ensuring the audio meets strict broadcast standards, making it the industry standard for stations ranging from local internet radio to international FM broadcasters.

Key Features

StereoTool’s dominance in the audio processing market comes from its robust feature set. Here are the core components that define the software:

• Multiband Compression and Limiting: Unlike traditional compressors that work on the entire audio signal, StereoTool splits the frequency spectrum into multiple bands (up to 10). This allows you to compress bass frequencies without affecting the treble, resulting in a tight, punchy sound without distortion.

• Clipper and True Peak Limiter: The software includes advanced clipper technology designed to maximize loudness without introducing audible artifacts. The True Peak limiter ensures that the output never exceeds digital zero (0 dBFS), preventing distortion in streaming platforms and FM transmitters.

• Auto-Gain and AGC (Automatic Gain Control): This feature acts as an intelligent volume rider. It automatically adjusts the input volume to a target level, ensuring that quiet audio is boosted and loud audio is tamed, maintaining a consistent listening level across songs, commercials, and voice tracks.

• De-esser and Multiband Gate: A built-in de-esser effectively removes harsh “S” and “T” sounds from vocals. The multiband gate helps eliminate background noise and hiss during quiet passages.

• Composite Clipper (FM Mode): For FM broadcasters, StereoTool offers a dedicated composite clipper that allows you to drive the transmitter harder while staying within legal bandwidth limits, maximizing the station’s reach and punch.

What’s New in Version 10.11

Version 10.11 continues Thimeo’s tradition of refining audio quality and expanding user control. Key updates in this version focus on stability and improved audio transparency:

• Enhanced True Bass Algorithm: The low-frequency processing has been updated to provide deeper, more controlled bass without muddiness, giving tracks a fuller sound even on small speakers.

• Improved AGC Behavior: The Automatic Gain Control has been fine-tuned to react more naturally to sudden changes in audio dynamics, reducing the “pumping” effect sometimes heard in previous versions.

• Optimized CPU Performance: Under-the-hood optimizations reduce CPU load, making it more efficient to run multiple instances of the plugin in a DAW or to stream at high sample rates (up to 192 kHz).

• Interface Refinements: The user interface has received minor updates to improve navigation and accessibility, making advanced parameters easier to find and adjust.

Installation Guide

Installing Thimeo StereoTool is straightforward. Follow these steps to get started:

1. Download the Installer: Visit the official Thimeo website to download the latest version of StereoTool. Ensure you select the correct version for your operating system (Windows or macOS).

2. Run the Setup: Locate the downloaded .exe (Windows) or .dmg (macOS) file and run it. You may need to grant administrative permissions.

3. Select Installation Type:

   • Standalone: Install the software as a standard application.

   • VST Plugin: Install the VST (or AU for Mac) plugin files into your DAW’s plugin directory.

   • Winamp DSP: Install the DSP plugin for use with Winamp or compatible players.

4. Choose Components: Select which components you wish to install. For most users, installing the Standalone and VST versions is sufficient.

5. Complete Installation: Follow the on-screen prompts to finish the installation. Once complete, launch the application or load the plugin in your audio software.

How to Use the Software

Using StereoTool effectively involves understanding the signal flow. Here is a basic guide to setting up a preset:

1. Select Input/Output: In the standalone version, go to settings and select your audio input (e.g., Line-In, Virtual Cable) and output (e.g., Speakers, Streaming Software).

2. Load a Preset: Start with a preset. Navigate to the prests menu. Choose a preset that matches your goal, such as “Web Radio Loud”, “FM Soft”, or “Voice Podcast”. This gives you a solid foundation.

3. Set the AGC: Go to the AGC tab. Adjust the Target slider. This sets the desired output volume. The Speed slider determines how fast the software reacts to volume changes.

4. Configure Multiband: In the Multiband tab, use the EQ curve to shape the sound. Raising the low bands adds bass punch; raising the high bands adds air and clarity.

5. Apply the Clipper: The Clipper tab is where you control final loudness. Adjust the Clip Level to increase loudness. Be cautious—over-clipping can cause distortion. Use the Pre-Amp setting to drive the signal into the clipper.

6. Monitor: Use the built-in meters to ensure you are not clipping the output (red lights should flash only occasionally). Listen for artifacts like pumping or distortion and adjust the settings accordingly.

Best Use Cases

Thimeo StereoTool is versatile enough to be used in a wide range of professional scenarios:

• FM and AM Radio: Optimize the signal for transmission. Use the composite clipper to increase perceived loudness and coverage area without over-modulating the transmitter.

• Internet Radio and Streaming: Ensure a consistent, loud, and competitive sound that matches major streaming services like Spotify and Apple Music. The True Peak limiter ensures compliance with streaming platform loudness standards (e.g., -14 LUFS).

• Podcasting and Voiceover: Use the de-esser and multiband compressor to create a professional, radio-quality voice. The AGC smooths out plosives and inconsistencies in microphone technique.

• DJ Mixes and Live Performance: Insert StereoTool as a VST plugin in DJ software (like Virtual DJ or Traktor) to polish the master output in real-time, ensuring the mix sounds punchy and clear on large PA systems.

• Post-Production: Use it in a DAW (like Ableton Live or Adobe Audition) for final mastering of tracks, albums, or videos to give them a broadcast-ready finish.
