Welcome to sonic beacon

Sonic beacon has been designing premium quality data acquisition and loudspeaker analysis software for the Windows Operating System since 1997. Our latest free of charge download allows the PC or laptop user to perform loudspeaker test and measurement using a low cost audio power amplifier, a measurement microphone and pre-amp and a multimedia compatible sound card or USB/Fire-wire audio interface.

Sonic beacon will perform frequency and phase response, harmonic and inter-modulation distortion, polarity, impedance, Thiele-Small parameter extraction, sensitivity and SPL as well as other FFT and real time loudspeaker tests. In order to maximize signal to noise ratios this program tests loudspeaker frequency response using the application of maximum length sequences (MLS) with FHT/FFT to extract the impulse.

This software application contains a series of modules that may be cascaded in order to perform a specific analysis on an electrical signal.† Data is passed and altered serially from module to module. A WAV/RIFF format input module, a signal generator, a sound I/O module, an oscilloscope, a spectrum analyser, a persistent data-logger and a WAV/RIFF format output module are included in this release. Sixteen bit sampling rates up to 192 kHz and FFT lengths up to 128K points are supported. Sonic beaconís standard data format is compatible with a wide variety of loudspeaker design and test packages. File and clipboard copy transactions in .FRD and .ZMA formats are now available for data transfer to many low cost cabinet and crossover design programs. Audio interface and amplifier calibration for the measurement of voltages and SPL as well as the application of microphone response curves are also standard in this release.

Sonic beacon has been used for loudspeaker and other audio equipment testing by acoustical technicians, sound engineers, scientists and students. It is ideal for prototyping of loudspeaker cabinets and crossovers. Best of all sonic beacon is absolutely free of charge.
