Optimizing Ableton To Avoid CPU Spikes While Livestreaming

Post by luckykat » Thu Jun 09, 2022 4:17 am

Been using Live 11 for about a year now with current setup:
32GB RAM, Focusrite Scarlett 2i2 audio interface, i9 processor.

Just started livestreaming on Twitch & things are pretty stable when there are only a few tracks & plugins being used.
However, when I start using multiple instances of plugins and especially when I use izotope ozone 9 or Waves H-Series plugins, I get CPU spikes, snap, crackle and pops.

Any suggestions on how to optimize Ableton/PC for livestreaming?
Any software/hardware that allows you to use as many plugins as you like without fearing the CPU tripping the 100% level?

thanks!

What does your performance consist of? We livestream our band every time we play and we use Ableton for our backing tracks and never have a problem regardless of the number of tracks. However, all our backing tracks are flattened to audio tracks ahead of time to reduce the loading and initialization processing of plugins.

I would look at your use of Ozone in a live context. It's quite hefty in terms of resource usage and buffering / latency.

What I tend to do is build a cheap Ozone on my master / busses out of Ableton devices, and I make sure to keep latency and resource usage as low as possible. In a live context it's not as important to have all the Ozone bells and whistles on because each song will be different - so its not like you can set and forget Ozone. What you probably have is a hipass on the bass, some multiband EQ / compression, limiting, saturation and a transient punch up of some kind.

So I just rebuild that in Ableton using Glue, EQ8, etc.
I punch up and carve individual busses, so the drums have a DrumBus effect for example.
In a live context I cant rely on presets, so I expose all the buss controls on a control surface

what it looks like broken out on a control surface (very slick and professional! :wink: )

Yep, you really don't need to use Ozone especially in a livestream context.
Just replace it with native Live devices and you should see a significant improvement.
