Title: what methods do you use to apply a "bass roll-off" in post..?
Post by: macdaddy on March 14, 2004, 08:01:21 PM
compression..?

EQ..?

both..?

what type(s)? how much?

I know alot of this is subjective, but I would like to know how some of you go about this task, as well as your thoughts on the matter...

thanks for any, and all, input and assistance.

I don't use any techniques after the fact, however the recording came out i leave it pretty much alone, except if the recording volume was a bit low i'll raise it a few db's.  It's mostly because i'm very much a newbie when it comes to tinkering with Audition regarding cleaning up a recording of mine.  :(

yeah I tend to stick with EQ, I just got done mastering a recital I taped for a friend of mine, I wanted to keep things simple so I used a cool edit preset called "simple bass lift".  there was also a "simple bass cut".

(Not to thread hijack, but) - Gloco,

Did you stealth that Frampton?  He's coming down here to SunFest soon, and I was wondering if he was hip to taping...

If I've GOT to roll off some bass, I usually use a parametric or graphic, or setup a low-pass filter.

What editing app are you using?

who doesn't think he can stealth TLM170's (but stranger things have happened).

Do you need to reduce the low end or cut out a low rumble or what? Obviously EQing can do both. What exactly are you looking for for an answer?

its all so dependant on the recording.  having huge multiband eq's in software such as sound forge and wavelab makes it so that you really dont need any sort of preset rolloff, you can just gauge it recording by recording

Bass rolloff by definition is a high-pass filter (EQ) set to a low frequency, usually 50-150Hz.  Any other process addresses another aspect to the sound.  For example a rumble filter is not bass rolloff, though having rolloff engaged and/or using a shockmount during recording might have prevented the need for a rumble filter.

Yeah, i did stealth the Frampton show, i'm totally clueless as to his thoughts about live taping so i snuck in my minidisc without any hassles.  The show wasn't too bassy, but i do recall his vocal monitor being a bit low compared to the rest of the band.  I use Adobe Audition, but then again, i'm totally clueless to how to use its features.  I stick to cd wave for transferring shows.

thanks for the replies...

I've been running DPA (4060) > SBM-1 (line-in) > d8

the bass can be boomy. when played back on my primary system, which is really top notch, the recordings sound great. But when played back on car stereos, or on my Karma, they are really bass heavy...

While I have the switchable batt box, I never use it because I run line-in. I guess I could buy the -22db att cable (signal s too hot otherwise), and use the rolloff filter and go mic-in, but isn't there a way I can set all this in software, doing what the box does with hardware?

thinking about it, I could use that as a starting point, and fine tune on a case by case basis. Some don't need anything - acoustic and/or non-PA shows. But the floor at Primus, GBA, and surely Phish in a few weeks :) can come out  quite boomy, and I would like to get rid of some of that, if possible...

for seeding, I just include a rough approximation via a foobar EQ setting, so the FLACs are unaltered...

but for CDs I burn for my non-taper/trader friends, and for my own curiosity, I would like to know what options I have via software...

Thanks again for all of the assistance and interest.

If you have a tape that has a lot of bass, you could probably get pretty close to which freqs you need to roll-off by running the spectrum analyzer, and lower it dependent on which low-end freqs are appearing really loud.

I recently picked up MIX magazine's "Mixing Engineer's handbook"  Which has  a great section on EQ.  It's in the context of mixing multi-track, but the insights on what to do with a parametric EQ are golden.  I recommend it highly.
