Test tone Generator

[randogdavis]

Are there any free test tone generators out there? My trial version of the NCH generator expired- wondering if there's another option.
:Thanks,

And speaking of tones, does anyone know the SPL conversion for SPL in 2.83V/1m to SPL in 1w/1m?
Thanks

What version of the NCH Tone gen are you using?
2.83V is 1 watt 8ohm and 2 watts 4 ohm.

v 2.01 I tried downloading the current version, but when I went to use it, it said my time was up too.

So does this mean that for an 8 ohm driver, the SPL rating in 2.83v/1m would equal the SPL in 1w/1m rating?

Thanks,

I have the same version. Mine never expired.

do you have WinISD? they have a basic test tone generator and i think it's still "freeware."
