The extra half a bit in REW comes from the rms level of a full scale sine being -3.01 dB relative to digital full scale. That's likely a...

Explanation is in the help: The upper limit for data used in distortion calculations is 95% of the Nyquist frequency (i.e. 95% of half...

REW's figures are for the selected bandwidth, 20 Hz .. 20 kHz in the case of that measurement. The ENOB calculation is correct.

OK, I have added a 16 or 24 bit choice for the next build and 16-bit is forced if saving to a 16-bit format.

REW doesn't have a 16-bit J-test signal, the signal is 24-bit.

Some countries do not allow PayPal donations, though I'm not sure why. If you would like to use PayPal's send money option instead the...

This has been very unexpected! Thank you so much to everyone who has donated, I really appreciate it.

For the beta builds, yes.

The home directory will be used by the installer if the user does not have or does not provide admin privileges for the installation.

That's the way I designed the measurement sweep to ensure sufficient low frequency energy to obtain a good impulse response and hence an...

Yes.

They are from the Dolby standards for AV processor level alignment.

REW's sweep starts at half the start frequency, so a measurement from 20 Hz starts its sweep from 10 Hz. As sweeps follow an exponential...

REW can apply mic in box corrections.

CCA magnitude uses some coherent averaging functionality that is only active when showing distortion, I have fixed it for the next build.
