>With the bosendorfer example, do we not hear mostly the harmonics of the low >notes in a recording and not much of the fundamental? I feel 'at home' (aka it is in my core range) with a freq of 35Hz (cis below the A-String of a bass) and I still can hear frequencies even below that (not just some harmonics). Don't know about 16Hz but I'd argue for something like 25Hz. While we are at it: the average Bass singer can produce frequencies of about 75Hz (between d and dis above Bass A-String). The good ones go down to even below 60Hz (H/B above Bass A-String). So be careful with your lowcutfilter when recording a deepsounding male singer with a deepsounding voice ;-) >Point is, that the original poster asked about removing certain frequencies >to avoid distortion when mastering for CD.

If you want to do that type of thing (be it for low or high frequencies) you might want to apply spectral analysis before doing so. That way you'll see wether these freqs actually chew up headroom. No need to bother if they don't. Best, Michael -- Vote against SPAM - see http://www.politik-digital.de/spam/ Michael Gerdau email: mgd@...
