Title: possible to extract audio from roms?
Post by: DYNAGOD on October 12, 2004, 01:07:05 pm
I have been playing aorund with dark basic and wanted to start making an admittedly simple game for the hell of it in my spare time.  i was wondering if there was a way to extract audio from rom files so i can have a sound base to work with. most if not all of the sounds in those classic titles are perfect and i have no desire to go recreating the wheel.


thanks

Look @ M2.

Don't have an address handy, just do a Google.

I came across this post when trying to figure out how to extract audio...

Thing is Dynagod... the older games use Synthesized sounds. That means there's NO data to extract. It's all programming through synthesizer chips.

You should just get a Wave editor (Gold Wave, SoundForge), set your recording to be "What you Hear" or "Wav/Mp3", then hit record, and then play the game...

Come back to the editor and edit the parts you want to keep and save them as your WAV sound files.

Well, there is data, just not in the form of an audio file. It would be cool if you could convert the data into a MIDI file, since that is essentially the same thing; i.e. instructions telling your sound card what tones to generate.

Well, not exactly. MIDI files are just information on note on/off volume, what instrument, etc. There are standard midi setups so that you can get a piano sound or guitar sound, etc so you can get an approximation to what the creator of the midi file intended.

But standard midi doesn't support the random beeping and booping that an arcade machine synthesizer can do. So midi isn't really applicable to this.

Recording the sound (hopefully without converting to analog) is probably the easiest and most accurate way to do it.

Dark Basic? how is it, I thought about buying it! is it easy for someone with minimal programing skills? [/thread_hijack]

Unfortunatly the main sound I'm looking to get is played when there is background music...  Meaning the sound I end up will have the music, which will keep it from sounding right...  :(

Welp... time to hooke up with a programmer. His challenge: Disable the music.
