Audio Post Basics: LFE Channel in Surround Mixing

Join me on the LIVE class as we talk about the LFE channel used in most surround sound mixing formats. Pro Tools, Davinci, Premiere, Dolby Surround sound - all can use the LFE channel, whether mixing in 5.1 or Atmos.

For the one who asked how to send the pink noise to the LFE, you have to go to SETUP in Pro Tools and then to the I/O. Make a mono sub path in your output and move it to the LFE position. Then you can select the LFE as the output of your pink noise track. May be the I/O setup could be an interesting subject for the next video. Thanks for this video Tom!

Hey Tom, I haven't watched this livestream just yet so apologies if you have covered this. I'd love to know what you considerations are for downmixing to LT RT - Do you make adjustments to the mix and does listening to the mix through the downmixer give you any insight into your mix that you may not have had listening in 5.1? Thanks!

If you are looking to become a dialog or sound editor, not a re-recording mixer, do you need a 5.1 setup in your studio or is a stereo setup adequate?

[@ThomasBoykin]

Nope

When i've calibrated sub 10 db louder than the front speakers(dolby -20db pink noise filtered by eq 120 hz 24q), every content in 5.1 like movies, tv shows or trailers sounded horribly boomy, the LFE was too hot. So i set LFEs spl same as front speakers and it worked for me. I checked my material at cinemas and the movie sounded just like in my studio in terms of low end. I've aligned sub with other speakers in phase via smaart app.But I still don't know why the LFE channel was too hot, i suppose theres something with room size or so.

What do you think about downmix to stereo with muted LFE? Asking because theres a muted lfe preset in avid downmix plugin

[@ThomasBoykin]

Depends on the show
