By connecting MPXTool to a tuner with an MPX output, an engineer can make off-air recordings of any radio station's complete MPX signal. This creates a perfect digital copy of everything that's being broadcast. Because the MPX signal captures all subcarriers, playing back this file in MPXTool will sound exactly as it would if you were listening with a good radio at that moment. This allows for objective, side-by-side comparisons of different stations or different processors.
MPXTool is packed with features that transform a standard PC into a sophisticated broadcast lab. Its key capabilities include:
Thank you for using MPXTool. Version 3.19.52 is another step toward a faster, more reliable experience.
The "MPX" in the name refers to the used in FM broadcasting, which includes the mono audio, the stereo pilot, and the stereo sub-carrier. This tool allows engineers to interface with hardware units to ensure signal integrity and compliance with broadcasting standards. Core Features MPXTool 3.19.52.zip
If the official developer forum provides an MD5 or SHA-256 checksum, verify your downloaded file matches it exactly before extraction.
: Increase the FFT resolution within the software options to 4096 or 8192 samples for a highly detailed look at narrow subcarriers like RDS. Lower the window size if real-time, instantaneous peak monitoring is your top priority.
Whether you are looking to benchmark different audio processors or ensure your station meets strict modulation standards, the package provides a comprehensive set of tools to get the job done without expensive hardware monitors. What is MPXTool? By connecting MPXTool to a tuner with an

Your goal should be to obtain the latest, official version of MPXTool from the trusted source.
A standard FM baseband composite signal (MPX) is not just a standard left/right stereo file. It is a single, complex waveform spanning a bandwidth from that packages multiple signals together:
