Title: Low Frequency Cut: Set it going in or with EQ Post Recording?
Post by: bilco on June 22, 2008, 01:56:39 PM: I just got the PCM-D50, which has 2 choices for low cut, 75 or 150. Even 75 is going to cut out some of the lowest notes on a bass guitar; the low E on a bass is ~ 42 and a 5 string goes even lower.

Are most of you just setting the low cut filter up front to be safe or do you record without a filter going in and then EQ with software when you are editing the wave files?

is it natural sounding, or, grossly bloated?

the hpf does not strongly cut off freq's at the specified point; it just begins lowering at that point, per its designated steepness.

Exactly.If you want to isolate/lower a specific frequency, use EQ.

Post by: Brian Skalinder on June 22, 2008, 03:52:39 PM: I rarely, if ever, use HPF in the field. I usually adjust in post if necessary, as I prefer having more control over the process than most field HPF features provide.

Post by: Liquid Drum on June 22, 2008, 04:06:22 PM: So by using 80hz roll-off on my CA-9100 I could be potentially ruining my recordings to a degree? Maybe I should turn it off...

I have a bunch of recordings where I've run hpf on one channel, and not the other, with intent. Fine sounding recordings.

interesting

in smaller chamber music ensembles, the bass will generally be in the right channel / right side of the stage. The treble players are to the left.
Because bass becomes omni-directional at around 300hz, I like to be able to ensure aural placement of the bass section in the captured recording. So i'll turn on the hpf to position 2 on the V3 left channel (75hz at 6dB), to help keep the bass in the right side.

That is great thinkin moke...

Post by: indietaperwloo on June 22, 2008, 05:37:48 PM: I'd only use it in a bass-heavy environment like a club or arena. Even then, I'd only use it in extreme circumstances and if I have to apply it, I apply it in post with Waves X-Hum with just the HPF and DC Offset removal - no hum removal unless there's hum to remove.
