Well done. More people need to understand this coming from stereo and just jumping into Atmos, having completely bypassed surround learning curves.
I think the original was pulled. But I suspect the Apple Spatial Audio exaggerates it.
Thanks! I do like to use the LFE but yes, it's definitely adding low-end in the Apple Renderer. Cheers!
Thanks. I think I’ll ignore the lfe in my next production. I’ve only done 4 released atmos tracks. I did some lfe experiments to see what Apple Music does. Discovered it depends upon the iOS and if the playback is an apple device or not.
For example. I had a version of a song that had a bass drop only in the Atmos version in the lfe channel. Played back on Apple Music on my out of date iOS ( at the time ) It played back on everything in binaural because indeed LFE was present and it sounded like a different binaural on everything. Then I updated my iOS a few months later wondering if things would change. Indeed they did. Now. On everything besides AirPods ( 3rd party devices via Bluetooth like car , non Apple headphones ext ) it’s the stereo fold down. Same phone and playback devices. Just an updated iOS.
Apple's Spatial Audio is definitely a moving target.
Great video!! This clarified some things about my system and how I currently have it set up. I just sent you an email about something very similar about bass management and phase. One of my favorite bands (The 1975) has an album that was released during Covid, and when I include the LFE for almost every song on said album, the low end is pretty much non-existent. When I solo the LFE, there is a lot of extra low end that isn't showing up when I have my bass management turned on. When I have BM turned off or I take out the LFE, it sounds tremendously better. For almost any other album by the band, it has been great Atmos mixes. Is this the result of a poor mix/translation?
My guess is it's related to a filter placed on the LFE channel during mixing, and then overuse of the LFE.
How much would it have been a difference by choosing an 24dB instead 12dB filter in the LFE high cut?
I'm not sure exactly, but it would definitely make a difference especially since I believe a 24 dB per octave filter will cause more phase shift.
