when parallel processing...

okay so lately i've been using audio damage panstation on a bus channel and sending basses to the panstation bus, that way the original signal plays, but then i mix in the panned version for stereo effects. however, my concern is will i introduce any phasing playing the panned signal over the original? if so, would throwing some light distortion on the panned signal do the trick?

Maybe.

Can someone more knowledgable please chime in and let me know if phasing would occur in this situation and a possible workaround if there is phasing? Thanks in advance.

I haven't used that VST, however if you panning/widening bass sounds and then mixing them back in with the original you more than likely will encounter some phasing issues, however you could just EQ the panned/widened version to cut the real low end (where you will encounter issues the most) and leave the midrange & upper parts of the sound intact - this way you can get a powerful central bass sound with stereo effects.

Edit: you could probably use some stereo/phase analysers to realyl detect if there are issues and then alter your phase accordingly, I think there are some VSTs that can flip phase of a signal - so you could effectively constructively add the phases of your bass + stereo bass, instead of having destructive phasing.

What's the pan station doing? Is that all you have on that buss? Delay, detune, eq and distortion would help keep it distinct sonically from the middle channel.

You can always run tests with sine waves or pink noise. Watch on a spectrogram and a level meter and see if any dips occur when you add in the send. You're gonna have to account for the volume increase from adding in the pan buss though so set them to easy to calculate levels, like both at -6dB. They should add to 0dB so measure any reduction with the sine wave at different pitches and check the spectrogram for nulls with the noise.

Yes I already do cut the low frequencies out. And as of now I just have pan station and camel phat on the bus for distortion. I'm not exactly sure I totally understand how to check the phase but I can try when I get home. Is this common practice for basses? I can't see just putting a auto panned on the entire bass signal. I'm thinking of Cookie Monster songs. Do you think he pans his basses on parallel? It sounds almost like he's panning the entire bass signal but I can't justify doing that whih is why I'm mixing it in in parallel.

Are you talking about panning or stereo widening?

Autopanning. But that essentially is stereo widening lol.

When I think of stereo widening I think of detuning and micro delay.

If I were you, I'd put it through a M/S matrix and just mute the center channel. Then you'll only hear the panner when it's on the sides and it won't fuck with your center panned shit.

phasing in your mids and highs isnt always bad. You might loose a power but if it sounds good then use it.

I believe maybe is the most helpful answer you could have received. It implies that you should try it and find out for yourself :)

how would i go about doing this in logic? i have waves h-eq and iieq equalizers which i know have m/s capabilities but to be honest i dont use it :oops:

thanks so do i put that on the autopan bus channel and solo the sides or what? sorry im not sure i understand fully i've never done such a thing before.

by the way do you know of any free plugin that is like reasons stereo imager in the sense that you can set a frequency and make everything below it mono?

Phasing issues will arise if the signal is identical or very nearly identical and they are played slightly out of time with one another. You can test it by listening for the phasey sound.

If you add distortion, you'll get a different signal. Whether the signal is sufficiently different to prevent phasing maybe depends on how much distortion you add?

Ultimately, where is the music going to be played? If it sounds good, why not just allow it?





The monoising plugin you mentioned are called monoisers. Examples include OtiumFX Basslane and Clone Ensemble although they are VST only.

For monoisation you may be able to use a stereo imager plugin like Waves S1 Stereo Imager, Izotpoe Ozone or PSP Stereo pack, all of which come in AU flavour. http://www.pspaudioware.com/plugins/too ... udostereo/

What happens in Logic when you just make the audio lane mono instead of the audio output?

Can't you see it in the waveforms?

Yea.

You can make your own monofilter track preset if you don't wanna get a dedicated plugin. Just send to two busses, with high and lowpass filters at the same cutoff. Linear phase is a good idea here. Then just use whatever stereo plugin to convert the lowpassed buss to mono.

izotope's ozone is great for determining if you have phasing issues in your signal, and you can also correct it with the stereo imaging section, although sometimes correcting it brings it to shit as much as a mono system would. if the sound in question sounds good going through a mono plugin is it safe to say it will be ok in a club? also, is there any frequency related rule of thumb as to where phasing is tolerable so to speak??

Just a thought, but why not try controlling the phasing to your advantage to create different stereo effects? Maybe I'm not fully understanding what's going on here though :dunce:

i took a closer look/listen and im not having any phasing issues with just a camelphat using a few diff types of light distortion and then the autopanner on after that. so no worries guys. thank you.
