whats the limit of stereo phasing?

Post by abort » Sun Oct 12, 2008 2:01 am

I was working with some peaces of work and realized wow this sounds really good in The headphones but dam this is going to sound like crap on the monitors.

My question is, how much stereo phasing can I get away with without loosing the game in the bigger picture here. I know someone will say "well whatever sounds good" but I was wondering if someone could produce some kinda chart or references about phase shifting and how it would be useful in a mix.

I know that stereo manipulation can be useful but its something that I have overlooked in the past ....

you should read up on what phasing is, there is no formula.
http://www.indiana.edu/~emusic/acoustics/phase.htm
looks pretty good.

phase is a very very small shift in time, smaller than the period of a single sine wave. in a signal like a song there are many sine waves at once (millions) so applying a small shift to all of them at once affects them all differently.

yes, use your ears.

thanks for the "°" I copied it from your post, how the hell did you write that?

exactly. its a very arbitrary thing, it will depend on on the frequency content of whatever you are listening to... usually (in studio situations) phase flip will change deconstructive interference. but it dont think that is your problem

is it the common problem of " it sounds shite on monitors after making on headfones??" i think that headfones in general lend themselves to that, because there can be little stereo placement perception, and a false bass response

yep ..sometimes I can create a whole other world inside those dam headphones but it sounds like shit on the monitors.

Can I just put a utility plug in and call it a day? joking, joking!!!

i know it oh too well :)

i think sometimes tho, that whatever u have produced on phones, needs just a bit of tweeking, before it resembles what u remember. some level changes, and in drastic situations, things need to be totally redone. this is life tho

maybe some advice would be, do not write for bass too often on headfones...
if you are writing bass heavy music. it is too hard to call, for me anyway :) i know mastering engineers on phones only!!! i still caant believe it

use the utility plug from time to time to bring the panning down to zero (basically sums the right and left to center) if it sounds fine there then you are safe, if there are serious phase problems it'll change drastically and sometimes things will disappear entirely in the mix.

just to make sure you understand this (you might, but I just wanna make sure) that a wide stereo spectrum doesn't necessarily mean you have any phasing problems

I guess we have crazy keyboard layouts here in Belgium. the ° is just shift + ) on our azerty keyboards.

on topic: watch out with phasing issues in the bass end of the spectrum, they might not be printable on vinyl.

I think your right about this. Not so much vinyl, they can work that out them selves :D but the lower end of the mix gets effected the most. the higher shstuff I suppose could do whatever it wants to.

Find some interesting comment on that in an interview I made with a mastering engineer: http://www.monolake.de/interviews/mastering.html
( the statement about the vinyl is rather at the end of the text .. )

Robert
very interesting indeed!
is this the guy that does Sleeparchive and/or Klockworks? I like that mastering on those vinyls.
