What's the problem? Describe what went wrong.

Certain notes in the Semifinal Battle theme sound wrong on LLE audio without the DSP firmware files.

What steps will reproduce the problem?

Go to any colosseum in the game, get to the third fight and listen. Mt. Battle should also work if you can access areas 7 and onwards. Compare with youtube uploads if needed.

Is the issue present in the latest development version? For future reference, please also write down the version number of the latest development version.

Probably, tested on 5.0-14853. The latest revision at the time of writing this is 5.0-14862 and there's been no changes to de DSP code afaik.

Is the issue present in the latest stable version?

It's probably always been an issue.

If the issue isn't present in the latest stable version, which is the first broken version? (You can find the first broken version by bisecting. Windows users can use the tool https://forums.dolphin-emu.org/Thread-green-notice-development-thread-unofficial-dolphin-bisection-tool-for-finding-broken-builds and anyone who is building Dolphin on their own can use git bisect.)

What are your PC specifications? (CPU, GPU, Operating System, more)

6600K
16GB DDR4 (2333 I think)
1060 3GB

Didn't test on my main computer, since I do have the DSP files there and had never encountered this.

Is there anything else that can help developers narrow down the issue? (e.g. logs, screenshots,
configuration files, savefiles, savestates)

HLE doesn't seem to have this specific problem though iirc there's still some issues with the HLE code that affect Colosseum, so I guess the only way to get perfect audio emulation on that game is LLE + firmware files. I guess it's not really a bug, since the firmware fixes this, but it would be nice to have it listed on the wiki.
