      Well, this is funny. Pro Tools under Rosetta runs faster on M1 Macs vs Intel Macs... But Apple's own Logic Pro runs much worse on M1, natively. https://www.itmedia.co.jp/news/articles/2012/16/news101.html … https://www.itmedia.co.jp/news/articles/2101/02/news014.html …

      I think this is a good example of what I've been saying all along: that the M1 is a great chip which is competitive with Intel and excels at many things, but that it all depends on the specific software.

      I expect things will improve over time, but before moving your workflow to M1 Macs, *test* whatever it is you're doing. Still looking forward to doing my own tests under Linux, especially at low buffer sizes :-)

      I suspect that the difference in memory size between the Macs affected the result. The author used reverb effects that might consume a large amount of memory. Still looking forward to an additional comparison with the same memory size.

      I can't imagine a single DSP reason for a reverb plugin to need more than a few megabytes of RAM at most.

      Honestly I'm not confident of my inference though :P but at least the Intel Mac in the article has 4x bigger memory than the M1 Mac and it might result a difference other than the difference of computational capacity. (BTW I started to donate Asahi Linux last month. Keep it up!)

      I want the author to show more values like a graph of memory consumption and CPU % etc.

      I agree that it would be nice to confirm, but I thought about this and concluded that a reverb plugin shouldn't be eating RAM. i.e. if it is that would be a giant bug, but I don't think the fabfilter guys are that terrible at plugin dev ;)

          Yes, I considered that. Sampling reverbs (i.e. convolution-based ones) should use at most 4x reverb tail length for the impulses (stereo cross pairs), which is less than 8MB per instance for a 10-second reverb time (which is quite long).
