: Generates an ideal composite MPX signal digitally. This signal can be routed through high-end, DC-coupled sound cards to test hardware FM transmitters, stereo generators, or limiters without requiring external hardware generation units.

A digital subcarrier transmitted at 57 kHz that displays station names, song titles, and traffic data on car dashboards.

Feeding baseband .wav or MPX files directly into an SDR transmitter configuration.

The mono audio compatible with older receivers (0–15 kHz). MPXTool 3.19.52.zip

The subcarrier transmitting text data like song titles, station names, and traffic alerts (57 kHz).

Facilitates "shootouts" between different audio processors by recording and playing back their outputs for side-by-side comparison.

Use a software patch cable like Virtual Audio Cable (VAC) to bridge your audio processor's MPX output straight into the MPXTool input.

is a software archive primarily used for the configuration, monitoring, and management of MPX (Multiplex) hardware, typically in the context of professional audio processing, FM broadcasting, or telemetry systems. Key Overview

: Adjust your transmitter settings and audio processing to achieve a perfectly flat response. Key Features of Version 3.19.52 Feeding baseband

For low-power FM operators, hobbyists experimenting with software-defined micro-transmitters, and broadcast engineers operating tight budgets, remains an incredibly useful diagnostic utility. It eliminates the need for expensive benchtop modulation hardware by converting any standard Windows PC with a capable sound card into a high-fidelity broadcast laboratory.

: Includes a reference-quality phase-linear stereo decoder to monitor how audio processors are performing.

If you cannot find a safe copy or need modern features, consider these alternatives:

An essential tool for European broadcasters, it measures compliance with the ITU-R SM.1268 standard (often called the Stokkemask), which prevents RF over-modulation.
