Hello,

I've been looking for a free signal generator software to test my speakers but can't seem to find one.

Any suggestions?

Thanks llyr

A basic sinewave generator that is fee and open source is http://wavb.sourceforge.net

It generates .wav files which you can put on a usb key or CD. Each tone can be preceded by a automated voice announcing the range of the frequency sweep.

Ltspice is a possible source generation option - it has a .wav output option and behavioral sources can generate any waveform you can write a consistent mathematical expression for

Audacity is another freeware source for .wav editing, playback/record and analysis

Ltspice could also be used for analysis/plotting as it can import .wav as well and then use the plot analysis options - read the .measure docs, and fft is easy too

Includes tone generator, o/scope, spectrum analyser and frequency plotter.

I downloaded it ages ago but never used it. Looks ok, but I can't vouch for its abilities

Not very good, quite old. I have been using the nice PC oscilloscape / analyser / generator at Visual Analyser 2011
