Hi thanks for the explanation. Possibly a better question to ask is: why do you want to sharply cut off at 30 hz -- an absolute shelf phenomenon? I wanted to show some people that frequencies do matter in orchestral recordings in order to create a sense of space and dynamics. So I hoped that I could...

Hello Try the AU high pass filter and set the cutoff at 30 hz. If you want a deeper cutoff, you can try using the filter twice. note that sharp filter cutoffs can create some really strange artifacts.

Hi,

How can I set a hard filter, e.g. cut off everything below 30 Hz?

If I use the AU LowShelf with a gain of -40 dB @30Hz, also Frequencies above 30 Hz get reduced.

Is there a way just to reduce frequencies bekow 30 Hz without touching the freqiuencies above?

Hello

sorry for answering so late.

I downloaded the new version and also trashed the preferences.
And it works!

Thanks to everybody!

Hello,

thanks for the hint, but there is no file rearding Amadeus or hairer in the preferences folder.

Hello, I deinstalled the software, downloaded the most recent version and installed it again. Same problem. The spectrum goes up to 250 kHz when 65k data points are selected. That's really bizarre. What can I do here? It worked up to one of the updates (I don't know which one it was). Cheers Babak

Hallo Thanks for the replies. What I want to achieve is to analyze, whether low frequencies are present in the sound file, especially those below 100 or 50 Hz, respectively. I am shure, I chose 65000 in the setting. With that setting the only correlation I see is that the frequency range besomes muc...

Hello I want to analyze a sound file, but the scaling is a little awkward. If I choose the spectrum size of 65k points (one extreme), I get a spectrum between 0 Hz and 150.000 Hz (see http://www.abload.de/img/spektrum1szy.tiff) If choose the size of 512 points, and I zoom in in the settings, I get a...
