Audio files with specific bitrates are played differently between RPG_RT and EasyRPG

[Mimigris]

Name of the game:

Yume 2kki.

Player platform:

Windows, 64 bits continuous build of the Player.

Describe the issue in detail and how to reproduce it:

When the files dedp足音1.wav and dedp足音2.wav are played in EasyRPG, they are played differently compared to the RPG_RT. It seems to be related to the bitrate of the files, but this may need more test with other files and attempt to recreate the issue with other files and see how they behave.

Where is this sound used (savegame next to it?) and can you check if this uses some dumb out-of-bounds pitch value?

If I'm not mistaken it plays in the Dark Museum (though where is it in it is another mystery).

Can you check if this uses some dumb out-of-bounds pitch value?

The issue reported here is with the default settings (100% speed) so it's not directly related to the pitch selected in-game.

There is somehow no curation before submitting stuff to Yume2kki, or is there?

I mean this one second of PCM Wave at 192 Khz (!) has a size of 750 KB. o_O

I played the audio files on Linux and in EasyRPG Player and they sound the same.

In RPG_RT there is a difference. So imo that is a problem with RPG_RT then because it plays the file incorrectly due to the high sample rate?

How does it sound on windows?

I get a quite similiar sound in the Player when I double the frequency to 192*2 kHz. Doesn't make sense why this happens. Guess there is internally some calculation overflowing because the frequency is too high. 🤷
