Thanks for the tips. Tried both, didn't sound as it should.

To get the room and apply it to other sounds in the mix. I have a bunch of reverb plugins but nothing can't even come close. If someone can point me to a plugin or an impulse response library that spits out such rooms, it would help. FYI it's a overhead signal from BFD. See attachment Sn BFD Overheads.wav

Hi, I got a dry snare and and the same snare wet. It's already recorded. Is there a software tool that i can feed with both samples and it creates an impulse response from the wet signal? Greetings

@des99 thanks for the info @exmachina you're welcome

cool

When testing i find it more helpful to seperate things CPU, RAM, SSD Stream. This gives more clear results and in the aftermath you can sum the impressions. The M1 Ultra is to expensive for me. Basic setting is twice the money.. for that extra I would rather by a analog synth. Mate, how about the fan noise of your MBP, do you come into situations where it bothers?

It's not the RAM cause on the M1 Air it takes only 20% in this test. A test with audio plugins and tracks is missing the point cause it's a CPU test. I never ran into CPU issues in such case, but with highload CPU Software instruments and reverb. I posted this to check how this test performs on other Macs espacially M1s cause i have only two macs to run this test. If there is an issue, there is an issue I don't expect someone in this forum to solve processor issues. But good news .. by changing the processor threads to 8 in Logics audio settings i had an improvement. 67 clean playback tracks with internal speakers as output device and Alchemy as softwre instrument with the Air M1 Compared to the 12 core intel Mac Pro it's still about -23 clean playback tracks (-25.5% less performance) but it's a significant improvement! I contacted Apple and wrote them about the issue. Maybe it helps. But for now it earths my hopes for CPU heaven with a mac studio M1 max.

Right, i did this test on the other machine a 1000 times. it would increase by 9 clean playback tracks too cause the Sculpture eats lesser CPU. The relation wouldn't change.

Compared to the previous test. Yes, the same test Alchemy replaced by Sculpture. It's not the plugin. If it would be I would be able to clean playback way, way more tracks.

I did the test using the Logics Sculpture plugin. No big improvement only 49 clean playback tracks, cause the plugin preset has a lower cpu load by default. So the plugin can't be the issue. Seems like the M1 ain't the kiler in this test compared to my old intel 12 core Mac Pro.

Ok, I will test it with another plugin and what happens when changing Processing Threads in the audio preferences. I picked Alchemy cause it's so heavy on CPU. There are two M1 Pro Prozessors: 8 & 10 Cores. Metric Halo had an driver issue with the 2D card. Basically I could run over 80 Tracks with it but only 20 with a clean playback in this. Adding more caused CPU "crackels" in the sound like digital noise or dirt. This problem was the reason why i created this test and that's how i found the problem.

Thanks for participating. This test is not only for me, it's for everyone to compare performances.

Your Results: (It's easier to read if you use this format) MacOS: Monterey 12.3 Mac Model: MacBook Pro Prozessor: M1 Pro (How much cores?) RAM: 16 GB Logic Version: 10.7.3 clean playback: 84 tracks with "USB audio interface" Output Device clean playback: 86 tracks with Internal Speakers Output Device Your MBP M1 Pro Geekbenches @ 1746 (sc) & 12231 (mc) if you have 10 cores My M1 Air Geekbenches @ 1705 (sc) 7415 (mc) with 8 cores (4 highperformance and 4 efficiency) You really think you have "double the high performance cores"? Couldn't find infos about that. Can you. check your Systim Informations > Hardware > Total Number of Cores: ? Thanks for the hint. Like I wrote, the Output Device is has an impact that's why listed different for my old intel Mac Pro My old Intel 12 core Mac Pro outputs more clean playback tracks than your MBP M1 Pro while it Geeckbenches much lower. That's the issue.

No, did Apple optimise the performance so significantly? there is a difference of of clean playback tracks by -50%. That's huge.

Hi friends, 2 years ago i set up an Logic CPU Test that simulated situations like having enough power but CPU spikes causing CPU dropouts stopping the playback It took some time to find the right balance but it was pretty helpful to understand how to deal with CPU settings, diffrent output devices can cause different results aso... I tested with: --- MacOS: Mojave 10.14.6 Mac Model: Mac Pro (Early 2009) Prozessor: 12 x 3.46 Intel Xeon RAM: 48 GB Logic Version: 10.4.8 - 10.5.1 --- Depending on the output device, I was able to (clean) playback 20 Tracks with MH2882 2D Output Device (MH had a driver Issue that caused cpu "crackles" at an early stage and only 20 tracks could be playbacke dean) 89 Tracks with Loopback Output Device 91 Tracks with Merging VAD Output Device This Mac Pro setup Geebenches @ 559 (single core) 3905 (muli core) Now I have an M1 MacBook Air 16 GB RAM too, and it Geekbenches @ 1705 (single core) 7415 (muli core) Following the Geekbench scores everybody would assume, the M1 Air preforms better in this test, but it doesn't, it preforms way worse! --- MacOS: Big Sur 11.6.1 Mac Model: MacBook Air (2020) Prozessor: M1 8 core RAM: 16 GB Logic Version: 10.7.2 Output Device: Internal Speaker clean playback: 40 tracks with Internal Speaker Output Device --- Temp Summary: My M1 AirBook with a 3x higher single core and 1.9x higher multi core Geekbench performance clean playbacks 2.25x lesser tracks in this test compared to my old Mac Pro. What is the issue? I don't know, that's why I opened this thread cause I want to replace my old Mac Pro with a new Mac Studio and this result confuses me. I would appriciate if folks in this forum, would do the test to, especially those who own a M1 Max to see if there is something wrong with my MacBook Air of it's a general issue that should be reported to Apple. 1) Please use the following Logic Audio Settings: I/O Buffersize: 128 Samples .... (if only playback, lower settings bring more preformance when you push the cpu to the limit) Processing Threads: Automatic Processor Buffer Range: Large Multithreading: Playback & Live Tracks Summing: Standard Precision (32 Bit) Rewire Behavior: Off 2) Please do the test with different Output Devices if possible. I tested my M1 only with the Internal Speakers cause all my audio Interfaces now have a ethernet connection and I don't have a thunderbolt adapter. 3) When you open the test project, you will see only one software instrument track loaded with an alchemy setting and a Bach midifile on it. Send 1 is open and points to an AUX Track with 5 Chroma Verbs in a row. Make sure all verbs are turned on. Stay on the set playback loop cause that's the part where the CPU always drops out cause there are midi glissandos. (more data at once for the CPU). You will see also an Midi Track. Some people use it to push the limit cause if you select the Midi track and start the playback, Logic says: cool, no software instrument i have to calculate if the user decides to play on on the midi keyboard and releases more cpu power. Is this a real world test? No, cause we are testing the CPU, but since I alway ran into CPU spikes in a production that caused CPU dropouts, stopping the playback, it simulates what happens when you run into real world limits. And no, don't let the test frustrate you, it is set up to start with an heavy cpu load. Download Link SPUMD Logic CPU Test Stop the playback, duplicate the Alchemy tracks (best in 10s), copy the midi region to the new alchemy tracks, playback again till the cpu drops out. Write the results in this thread providing the following informations: (p.s. close all other applications like safari while testing) --- MacOS: xxx Mac Model: xxx Prozessor: xxx RAM: xxx Logic Version: xxx clean playback: xxx tracks with xxx Output Device --- Thanks for participating.
