Mac M1 version

[ghost]

Hi

I have a MacBook Pro M1 having a M1 ARM processor.
I can't find a version of audacity for my Mac. The intel version doesn't do anything (it doesn't start). I have no Intel processor, that's all I know. It's the Apple M1 processor I have. Mac OS is latest version too.

Is there somebody who can provide a version?

Itel version runs just fine for me. Do you have Rosetta 2 installed?

Sorry i'm not an expert.
What are you talking about?

I just tried audacity intel version but it doesn't do anything.

Rosetta 2 is a program that allows Intel programs to run on M1 macs: https://support.apple.com/en-us/HT211861

I agree that the Intel version works on M1, but an Apple Silicon or Universal version would improve performance even more

Using Audacity on my M1 laptop runs at 100% cpu scrolling around, playing audio and the UI runs at 3 frames per second.

I support this, especially exporting could be much faster if the app would be optimized for M1 Macs.

This is an issue that I'm working on right now. I'm afraid it is not related to Rosetta and won't be fixed by ARM build.

We do plan on adding ARM builds anyway :-)

@crsib

Okay, thanks for your kind & fast response! Appreciate your work!

[andrew-jolley]

@crsib ok thank you. That’d be great to see soon!

For those unaware, apps run in rosetta 2 -- while amazingly performant -- still use meaningfully more battery and cpu than those running native arm.

That said, are there things that those of us in the community with development experience and m1 macs can do to help?

I just compiled latest Audacity from a source and it works great so far natively on Apple Silicon.
Everything for ARM64 support is already in place.

Steps for those who want to try before official release

cmake -DCMAKE_BUILD_TYPE=Release -Daudacity_use_mad="off" -Daudacity_use_id3tag=off ..

In cmake-proxies/cmake-modules/AudacityDependencies.cmake
replacelist( APPEND settings "arch=x86_64" ) list( APPEND settings ENV "CONAN_CMAKE_SYSTEM_PROCESSOR=x86_64")
with armv8

In cmake-proxies/libsbsms/CMakeLists.txt set( ENABLE_SSE NO)
In cmake-proxies/libsoxr/CMakeLists.txt delete SIMD
In lib-src/libsoxr/src/util32s.c delete SIMD

Edit: Forgot to write, in CMakeLists, replace CMAKE_OSX_ARCHITECTURES with arm64, better to use this branch #2343

Can you quantify the performance benefit?

I tried doing all your steps @EETagent but XCode just doesn't build it in the end...

It seems like it tries to build x86 things but fails... I don't know since I am not a a programmer and I need this for school...

[EETagent]

I do not have Xcode installed, nor Rosseta 2, so i can't comment on that or Intel build performance, used Unix Makefiles generator for building

If the application's launch is completely broken, and doesn't even bring up an unknown developer's window, you'll need to codesign it yourself

xattr -cr /Applications/Audacity.app

codesign --force --deep --preserve-metadata=entitlements,requirements,flags,runtime --sign - "/Applications/Audacity.app/Contents/MacOS/Audacity"

codesign --force --deep --preserve-metadata=entitlements,requirements,flags,runtime --sign - "/Applications/Audacity.app/Contents/MacOS/Wrapper"

[jacop5]

Amazing! Thanks a lot!
I can't use FFmpeg for some reason though.

You can compile FFmpeg yourself and then link Audacity against your libavcodec dynamic library from settings, FFmpeg exports works fine from my testing

https://ffmpeg.org/releases/ffmpeg-4.3.1.tar.xz 4.3.1 works for me, master doesn't, I haven't tested another versions or ffmpeg from homebrew

Great, I'll let you know as soon as I get it working

[jacop5]

I managed to get it working by using the ffmpeg version I had previously installed via Homebrew by pointing to /opt/homebrew/Cellar/ffmpeg/4.4.1_3/lib/libavcodec.58.134.100.dylib.

@danielktdoranie & @jacop5

Did you see #2223 (comment)?

[LWinterberg]

Please refrain from adding endless +1 comments. ARM support is planned and +1 comments won't make it go any faster.

@danielktdoranie & @jacop5

Did you see #2223 (comment)?

Yes, I did. But since Audacity is really popular and M1 macs have been out for a while I was expecting to find an official build... and most of all, I expected it to work without lagging

But I found a workaround for the Rosetta build

Yep. Poster says “it’s coming” so is next Christmas. Should already be done.
