Using Speaker Impulse Responses for Mix Portability

Mixing for portability across a number of playback systems and environments is a struggle for me (e.g., the feedback loop between trying a new eq setting and auditioning in the car is brutal).

I started using the following technique, which is pretty nice for getting a good percentage there, without the pitfalls of dashing to every audition environment.

Load Speaker IRs into a convolver as the last plugin on the mix buss.

Is this obvious? Do many people do this? It seemed like a nice tip to share!

What a clever idea vo1k1!

How is this working for you? Do you find you’re getting an adequate representation of the different speaker types using this method?

I suppose that its impossible to technically get 100% the sound of say a car using this method, seeing as its still yor monitors making the sound, and its still bouncing around in your particular mix room, but I don’t suppose this would really be an impediment to it practical use.

I’m heading over to gearslutz to ask the honcho’s what they think, keep an eye out for the thread.

I posted it in the mastering forum. I just looked at the link, and its come up with your tag in part of it. Sorry, I didn’t think that would happen. Want me to delete it? I don’t mind.

Hey SP, glad you like the tip :)

Please go ahead and post at GS! What is the URL? I did have a post on the subject, but did not get a reply. Maybe your post will market itself better :)

It is absolutely not a 100% solution for a number of reasons (like the ones you note). But it is very good at *quickly* previewing and revising with several *emulated* speakers/environments. So, depending on your time and resources, this can be a real advantage.

Post the GS URL? Also, if you try, let me know how it goes?

I’ve never dared to fire a gun shot in my car to record the impulse response :-)

I’ve had the painful experience of turning my car around on the way to dropping off DIY masters.

But all that nonsense stopped when I got a pair of real speakers and a sound level meter - plus four years of trying to get better.

now I’m not saying my DIY mixes are perfect or even consistently professional sounding but since I got that setup I’ve stopped racing around the house and the car with and without headphones and ipods etc. to get the basic thing done.

I just splurged on a pair of these :-)

Nice :) How well does the room correction stuff work for you?

shooting the room was very quick to set up and perform: plug in the little special mike into the left speaker, put that mike to where I usually sit, press a specific button sequence on the left speaker, and 10 seconds later it’s done.

While I’m not a professional sound engineer, the one thing I noticed immediately is, that the sound out of the speakers seems so incredibly smooth. No harsh sonic edges anywhere. So I think I’m definitely suffering from less ear fatigue than with any other sets of speakers I’ve had before.

heh - well, it took 18mos to pay mine off.

The scary ones are the $20k version that they have at my son’s audio engineering school.

hehe - at least you’ve generated some revenue with your music - while for me the pay-back curve (in a P&L sense) is firmly fixed pointing at infinity :-)

I like that post. For me, getting something bounced that is competitively loud for mp3 distribution is a real problem, in terms of esthetic quality.

yeah - compression for loudness is both a hideous thing from an aesthetics perspective, and on the other hand a vital thing from a practical perspective. I practically never listen to music in a serenely quiet environment, so soft passages get drowned out unless compressed.

I often even wish classical music was compressed a little more, or ideally speaking: car stereos (or any music system) should have compressors, so one could adjust the compression during playback rather than during mastering.
