Problems with ogg files?

First try this, select the WaveLab Cast app, press Command+i, in the Info window that opens, see if it has a place to check to run in Rosetta. If it does, mark it then open WaveLab Cast and see if it will open the .ogg files.

FWIW, VLC should open .ogg files as well. https://www.videolan.org/vlc/

Handbrake can open .ogg files and convert them to a different audio format.

https://handbrake.fr/downloads.php

Go to this page, right or control click on any of the download buttons and save the link. FWIW, from what I see, some .ogg files will open, some won't. All the ones from this page open.

Can try to update...

Post back with the result.

Just to add, you can see if MediaHuman Audio Convertor will convert the .ogg files.

Q - " start WaveLab Cast in Rosetta 2 mode”. Not sure what that means."

A - To answer the Rosetta 2 aspect of your question Only.

If you need to install Rosetta on your Mac

Rosetta 2 is only available on Apple Computer with the Silicon M1 / M2 CPU. 

Terminal Command 

softwareupdate --install-rosetta

There are three categories / types of software that can run on the Operations System.

Only Intel Binary Code. This software will invoke Rosetta 2 to translate the Intel binaries so the operating system can understand and execute the Application. The Applications must be 64 Bit to function on Big Sur, Monterey and Ventura

Universal Binary Software.  It contains Both Intel and M1/ M2 ARMs binary code and refer to (  Universal 2 ) When the user installs a 64 bit Application that contains Both Intel and M1 / M2 ARMs binaries - depending on factors, the Operating System may or may not invoke Rosetta 2.

“ Apple Silicon “ Checking in System Information >> Applications  >> as of now, only see One Application classified as Apple Silicon and that is “ Rosetta 2 Updater “.

That would make perfect sense since. It is specifically designed to operate only on Apple Silicon M1 / M2 ARMs based computers

Hi P. Phillips,

Thank you for these suggestions.

So, if I understand correctly, I can install Rosetta 2 on my MacBook and this will allow me to import ogg files into Audacity, WaveLab Cast, etc.

But are there any problems associated with this? Will Rosetta 2 interfere with anything else while it is “working in the background”? 

Rosetta is a translator for Intel code. The VST-2 plugin is Intel. It has no Apple Silicon native implementation.

You have to tell WaveLab to open using Intel code through Rosetta interpreter. WaveLab is "Universal" in that it can run on both Intel or Apple Silicon. The plug-in cannot.

Rosetta doesn't "work in the background." It just interprets Intel code for the apps that require it.

Is this the Specific Computer involved in this issue ?

MacBook Pro (16-inch, 2021) - Technical Specifications (CA)

Normally, when a Third Party Application that contains only Intel Binaries and is coded in 64 Bit - the Operating System would Prompt the user to Download any updates for Rosetta 2 without User Intervention required ..

If the same Third Party Application contains Both Intel and M1/ M2 ARMs binary code, depending on factors, the Operating System may or may not invoke Rosetta 2.

To Verify of the Third Party Application, go to Application folder and select the Application in question

Use the Get Info using Control Click

Examples for point of references as to what you are looking for

The first Application below is Intel Based and is 64 Bit. Therefore on an Apple Silicon computer Rosetta 2 would be invoked

The Second Application below is Universal and 64 Bit.

FWIW, I was mistaken about Handbrake, it will not open an audio .ogg file. However, I can open some .ogg files in Audacity, IINA, VLC even Firefox. The .ogg files you have however, may have been created with a codec macOS doesn't recognize or isn't installed. That could be why you are getting the VST 2 plugin message.

As an aside to your Main Question.

Much like, back in the day, when Apple was transitioning from the PPC to Intel based computers, there was a translator called Rosetta.

there was a period when Apple decided the Developers had had enough time to re-code their Application to run Natively on the Intel Machine Code

There after, Rosetta was no longer included in newer versions of OS X / macOS

Based upon a similar progression to present day.

Apple has now completed the Transition from Intel Based computer to All In-House ARMS Apple Silicon Machines.

It would be reasonable for Apple to follow a similar Strategy at some time the future.

Only Apple would know just if or when.

With this in mind, you may start looking now, for Alternatives for this and other Plug-in while it still is working instead of when the " Door Closes " on Non Native Apple Silicon plug ins.

Use the support site for Audacity and WaveLab to resolve these non-Apple sourced issues.

The only thing i can suggest is to contact Audacity Support
