Because you don't know the exact amplitude or phase of the ADC filter and you can't measure it directly without other components and...

Gotcha, thanks for the info. This seems like another confirmation of @KSTR's findings regarding how a very low frequency HPF can limit...

Correct. The theory was that the RME devices have a DC filter, with a very low frequency cutoff, below 1Hz, that also acts as minimum...

Revisiting my older ADI-2 Pro FS loopback recording. It appears that a minimum phase, low corner frequency HP filter benefits the RMS...

What a silly comment! The manual tells you how to connect the ground, there is no problem whatsoever doing so. The RIAA curve is much...

Interesting... I used the same 0.01Hz minimum phase filter with my own ADI-2/4 SE Pro capture, and it improved RMS difference from -78dB...

Mani, you might like this new version :) https://app.box.com/s/h2u20jzre4bake02n5aj40kc5r2woaa0 (because it's the same version number...

To get a deep null at LF, we want to make the frequency response of magnitude and more importantly phase the same for the compare. The...

Try it and see. The larger issue with the filter is not that it causes damage below 10Hz, but that it causes phase change over the...

:D

Bollocks. Now the bot is getting Shannon-Nyquist wrong and stirring it into the pot. Automated Brandolini.

For convolution with a large FIR filter, DW uses an overlap-add method that requires a minimum of n + m - 1 size for the FFT. In effect...

Thanks Paul. Much appreciated.

As much as I hate to remove new functionality, I decided to not add the DC filter to DeltaWave, after all. Instead, I extended the...

Windowed FFTs and STFT have been in use for as many years as audio has been around (applied extensively in DeltaWave, of course)...
