Music plays quiter than in Mugen

[Kiwi1444]

Describe the bug

Music in Ikemen Go plays quiter than in Mugen 1.1

To Reproduce

1. Set the sound in Mugen and ikemen Go to the same volume levels (I set the master volume to 35 and BGM volume to maximum).
2. Make sure that the sound level of Mugen in Windows mixer is at the same level as Ikemen Go
3. Record the first 60 seconds of music on the selection screen (I recorded with WaveLab)
4. Let's compare the two records:
   Mugen:
   
   Ikemen Go:
   

When analyzed in SounForge, I got that Ikemen Go plays music 7.5-8 db quieter than Mugen, which is quite significant

Expected behavior

The volume level of the music is equal to Mugen

I'm not sure if replicating Mugen's volume is one of our goals. Ikemen's looks a lot more like "35%" than Mugen's there.

[Kiwi1444]

I use both Mugen and Ikemen Go and it's not very convenient that the sound levels don't match. Especially when it comes to recording and editing video

[potsmugen]

You only need to make them match once though.

[Kiwi1444]

I will, but I'm just informing you of a difference between Ikemen Go and Mugen that I've noticed recently. I thought it was important

[Jesuszilla]

We're aware of differences. Due to differences in audio libraries, their implementations, and the different functionality the library we use provides, and due to the nature of working with audio, it's just not something that's easy to fix unfortunately.

Furthhermore, this comment exists in our code base for BGM volume precisely because attempting to address this in past nightlies only led to even more complaints from users:

	// NOTE: This is what we're going to do, no matter the complaints, because BGMVolume is handled differently
	// than WAV volume anyway.  We've had problems changing this in the past so it's best to keep it as-is.
	volume := -5 + float64(sys.cfg.Sound.BGMVolume)*0.06*(float64(sys.cfg.Sound.MasterVolume)/100)*(float64(bgm.bgmVolume)/100)
