Cannot import opus

[jadenquinn]

Bug description

I had this issue before, but it would just crash Audacity as soon as I try to import an opus file, but now it just says it can't recognise it and that I should import it as raw data, but it's not uncompressed... so that didn't work and would probably damage my speakers.

Steps to reproduce

1. Open Audacity.
2. Try to import opus.
3. Go on Github to complain after google searching for an hour.

Expected behavior

I expect Audacity to not only recognise an opus file, but know how to work wiht it, and be able to export an AAC version to boot!

Actual behavior

It... not doing 5% of that.

Audacity Version

latest stable version (from audacityteam.org/download)

Operating system

Windows, macOS

Additional context

Tested on MacBook Pro (Maxed out, 16-inch i9 2019) on SackOS 12.6.3.

Trying under Windows with an opus example file -

• Drag'n'Drop of the file works
• File -> Open works
• File -> Import -> Audio works

Can you open the file I linked too? If not, can you send the zip that Help > Diagnostics > Generate Support Data gives you?

[jadenquinn]

Yea no doesn't work. It doesn't crash Audacity anymore but it doesn't know what it is.

Testing under Macbook M1 Pro also shows no errors. Opening and playing the opus example file works just fine.

How did you accomplish this? It just says it can't recognise it. If I try to import it raw, it's just... noise. Really LOUD noise. I'm on a MacBook Pro 2019, so Intel.

Works fine for me on W10 with 3.2.4

From here (#4287 (comment)), to answer this question, Audacity doesn't crash when I try importing your file, but it's just as useless, as it just says it doesn't know what the frickle it is. I am on MacOS, however. I do not care how it behaves on Windows though.

In my case, this was happening because I had not yet configured Audacity to find the avformat*.dll shared library from my ffmpeg installation.

To fix this, first install ffmpeg if you have not yet done so:

winget install "FFmpeg (Shared)"

Then make sure that Audacity knows where to find the relevant avformat*.dll by going to Edit | Preferences | Libraries:

After doing these steps, I could import Opus files.

Here is the audacity documentation on installing and configuring ffmpeg: https://support.audacityteam.org/basics/installing-ffmpeg

As far as I've used this, it works perfectly fine now.
