Donkey Kong on MAME - sound quality not accurate

Pages: << < (5/8) > >>

Jack Burton:

There's a DK cab in a bar near here and the sound on it definitely sounds more muffled and bass heavy than when I play the newest MAME through different kinds of speakers, with exception of Mario's walking sound, which sounds a lot sharper.  I have a big Mitsubishi TV that I've played it through and it sounds good, but different.

I'm thinking it's mostly just the acoustics of the cab and the type of speakers used in that era.  

There's a couple of guys on this forum with MAME'd DK cabs.  Might ask them.

While I am interested in the solution to this situation, I'm wondering whether this is going to turn into an equivalent of King of Kong. 'Did you use a real Kong board?!'

Of note are that Mario's walking sound does not fluxuate in the above-linked recording. In the retro, tape recording at Coin-Op Videogame.com, it does.

CrazyKongFan:

There is a separate audio pot on the PCB. I have a cocktail, which has a 4-board stack, one labeled "audio". The pot is on that one, and adjusts either the digital or analog sounds (can't remember which). That being said, mine has a problem where sometimes, it sounds muffled, and sometimes (usually after being in the cold) sounds perfect. I don't think it's the audio board in the 4-board stack, because I have 2 of them and both act the same.

RayB:

First as has been mentioned, I'm pretty sure the sound hardware is designed in a way that renders the sound best, and this just isn't emulated since it is all audio components as opposed to "computer logic" parts.

Second, you're unfairly comparing the sounds with your examples. a WAV file is uncompressed, while your MP3 is compressed down to a cruddy 64kbs bit rate. Crisp highs are the first thing to suffer with MP3 compression and the lower the quality the more muffled the sound. So... you should be posting an uncompromised WAV file instead.

you're right, I didnt realize it only converted the mp3 at 64kps. I have replaced it with a WAV file. However, it sounds pretty similar to the mp3 to be honest.
