Sound Leveling
BadMouth:
I think you are taking it a bit too far. I just want them at similar levels.
I'm not tuning an EQ and they don't need to be exactly 80dB by strict industry standards.
Model of phone shouldn't matter as long as the same phone is used every time.
Running line out to line in is an interesting proposition and would be much more accurate.
I'll keep that in mind.
I was thinking about where to adjust the volume at.
It does make sense to do it in MAME. Not sure what is going on with MAMEPlus that I am testing on, but the volume up and volume down aren't working. The Master Volume "~" resets when I exit the game and restart it. After a little searching, looks like the Master Volume isn't saved anywhere on the official MAME build either. The slider controls are stored in the game's cfg file, but you have multiple sliders per game which sucks.
The worst offenders on my cab run on emulators other than MAME, so I'll adjust those in the service menu first.
I can't get to the service menu of a couple of the Taito Type X games, so I guess my ahk scripts for those games will just keep evolving. :lol
I was extremely picky about the sound quality on this cab.
I'm not compressing or clipping anything!
I got a bit nostalgic after mentioning my old audiocontrol, so I went to their website.
They haven't changed anything on that RTA in the past twenty years except for the color of the carrying case. :lol
I do see they make a mic that plugs right into an iphone/ipod though.
Looks like a sweet setup, but I have a windows phone (don't make fun).

Windows Loudness Equalization
Windows includes a build-in Loudness Equalization feature, although some sound drivers may not support it. The loudness equalizer keeps sound output from all applications on your computer within a consistent volume range.
To enable the loudness equalizer, right-click the speaker icon in your system tray and select Playback devices.

Came accross that "tutorial" earlier.
It doesn't actually do what he says it does. :P

Do you know exactly what frequency our hearing centers around? I'm going to have an equalizer in my cab, and I was thinking of singling out this frequency while doing this type of testing.

Load up an audio recording/mixing program and create a new track. Make the track's input your line level in and change the output to a buss assignment to avoid feedback. Load up an audio meter plugin on the track and check out the weighted rms values in there.

Kind of what I was thinking, but I think it would be a lot better to go from the line output of the MAME PC to the line input of a laptop or another PC. That way, someone could be playing the game while the signal is being analyzed on the separate computer.

I took a look at your build thread. The speaker box you integrated into the cab is pretty impressive. I'm planning the exact same idea, but maybe with a sealed box instead of ported.
This being said, did you "acoustically calculate" the optimum geometry and dimensions inside the box? If not, you probably won't get a totally flat response. I'm not saying I could do better; just saying I'd highly recommend a nice analog equalizer to really optomize your sound quality and get the most out of all that work. It really makes a difference, especially when you have to make compromises to fit things into an arcade cabinet.
