Extreme energy use on M1 MacBook Air.

(1/2) > >>

Hi, I’ve just installed MC28 on an M1 MacBook Air, 16G memory.

Whilst using MC28 I noticed that the battery was depleting quite quickly and on checking Activity Monitor I can see that MC28 has an Energy Impact value of ~86 when playing music. When no music is playing it is down to ~0.5.

When I open Audirvana (used since getting the MacBook last year), it also has a similar idle value and the Energy Impact only goes up to 0.9 when playing music.

I’ve let MC28 play for a while but the value is consistent as is the value when not playing.

All my music is stored locally on the MacBook, none of it is compressed.

MC 28.0.64
M1 MacBook Air with Big Sur 11.6

Any ideas? It’s not really useable with this power draw - assuming the Energy Impact values are correct.

LilyAarseth:
Not sure if this is the right solution, but left and right spectrum analyzers use a lot of cpu power when playing music, maybe if you disabled those two it would help a bit?

verloc:
Thanks Lily, that has resolved a substantial part of the energy use, it’s now down to a relative value of ~10. However, this is still 10x higher than I get with Audirvana.

I can also see the battery time vary as I change between programs too.

Is this expected power use? Is there anything else to turn off to improve consumption? I’m already running it in Audio Only Mode.

JimH:
There are several processes that occur in the beginning that will end.  Import, audio analysis, etc.

Thanks Jim.

I've been playing music with MC28 for over 3 hours now and it's still at ~10, if I activate the spectrum analyser the Energy Impact goes straight to 85 and stays there. There is no variation in these values and they are the same after this 3 hours plus of playing.

I doubt it's to do with import, audio analysis, et cetera unless these processes aren't closing down as expected.
