Thanks for that Bill.
I just put it into wavelab will be very useful. I will take some more output results when I test an audio amp, but it sounds great on the computer.

Thanks for the link. Very handy, yesterday I lugged a heavy audio signal generator to an old peoples meeting where I gave them a short talk about sound. Thought it would be fun to let them check their high frequency response on there aging ears This program on a laptop would have been far more convenient.
I like the option also for pink or white noise.

Just for info, it also runs on Linux using the Wine runtime environment, though the amplitude sliders don't work. This isn't really a problem as the output can be controlled with the standard system controls.

However, Linux users may prefer the native Jack/Alsa Audio Analyser, which in addition will do audio analysis though it can't generate white or pink noise (I don't think). The screenshot shows an analysis of a line channel with nothing plugged into it, i.e. the noise floor.

For Linux users, the 'sox' command line tool can generate raw data for test tones and noise.
I can post a selection of commands if anyone is interested ...

Hello everyone. I downloaded the Marchand function generator and it works a treat. Dead simple, there's nothing on or about it that doesn't contribute to the task at hand, nothing you don't need but good enough to make it really useful. Nice one! Thanks for flagging that up.
Regards,
Paul
