Has anyone used the 3D frequency analyzer in WaveLab? Is this thing worth a damn? |

Are you referring to this?
If so then the help file states
"This function allows you to view a wave file in the frequency domain rather than in the time domain. Although a wave display (time domain) tells you a lot about where one sound starts or ends in a file, for example, it doesn't say anything about the timbral contents of the file. A frequency graph (frequency domain) does.
The graph used in WaveLab is actually something often referred to as an FFT (Fast Fourier Transform) plot.
The graph can be used for example for the following purposes:
To see how the frequency spectrum is distributed in a mix.
As a basis for EQ-ing, so that you know which frequencies to reduce or boost.
To see which parts of the audio spectrum a certain background noise occupies (for removing by filtering).
For educational purposes - these graphs tell you a lot about how different sounds are "built"."
It can be handy to get a rough overal representation of the frequency content at any one time, the higher the mountains the more level is present at that particular frequency.
Does that help?

Ya. I still think thats crazy. I can understand how it tell all that, but at the same time can't. I just stick to the old school way. But yes that does help alot. Thanks. |

Thank you for the in-depth reply!
I was asking because this graph gives me some strange readings sometimes. Once I was working on this Industrial-Metal track, and it just had way to much high-end and a little to much mids. I wanted to pinpoint the certain high freq that was bothering me, but when I did the freq analysys the thing read totally flat ( like- NO little mountains or anything) EXCEPT- there was a mountain right at 20hz that was 20 feet (or metres for you guys) tall! I will admit that the track was quite thumpy, but I really don't think that I had that much in the low-end! But wait, I'm not done!
After that I had another track (about the same type of music). This track sounded almost the same as the first but when I did the freq on this one, the readout was EXACTLY the OPPOSITE! There were mountains everywhere EXCEPT for 20HZ! Didn't make any sense to me at all. I try to find a balance between my ears and these freq analyzers but I don't know how to take that!
What do you think? |

| Cross Check |
|
|
If I were you I would use your ears along with making some meaningful comparisons with some commerical tracks in a similar niche to your own tracks.
You can cross check (visually) by using some of the other tools also:
Spectrum meter
FFT Meter
Regarding your 20Hz problem, you can simply use a filter and remove everything below 20Hz, it's not needed and simply wastes bandwidth.
