Can anyone recommend a free Frequency Generator that I can download and use it in my notebook. The reason why I want a Frequency Generator it test some lounge shakers as I have one particular frequency that is pissing off my shakers The range I want to test is from 15 Hz to around 80 Hz. The way that I will test is via the audio output from the notebook to the input to the shaker amp. Also it might help where to download it from
Thanks
