True Audio's TrueRTA v.3.1 is a PC-based real-time analyzer (RTA). The TrueRTA includes a low distortion signal generator, digital Voltmeter, dBu meter, dB SPL meter, crest factor meter, dual-trace ...

Only LED displays that are made to display text. <BR><BR>An all-hardware audio spectrum analyzer is a pretty simple beast... particularly if you don't need it fancy, calibrated, useful for real ...

One of the most useful pieces of test gear to become generally available to the average broadcast engineer in the last 20 years or so is the spectrum analyzer. This electronic tool, while still rather ...

[El Artis] just finished building an audio spectrum analyzer that uses a character LCD. The uses an Arduino to drive the display, but unlike other meters that use the microcontroller for analysis, [El ...

[Simon Inns] just rolled out his latest project, a PIC based spectrum analyzer. He’s using a Fast Fourier Transform routine crafted in C to run as efficiently as possible on the 8-bit chip. The video ...
