I’ve decided to do further research into other games I like to understand a bit more behind the process of sound/music creation. To expand my knowledge and learn more techniques and ways of working. As well as potentially attempt them for my game.
Old School Runescape is a 2007 version of Runescape. The game is something I played in 2007 and to see them re-release the same version is amazing. The music is very nostalgic and uses old school midi instruments and sound effects sound like synths. I want to do further research just to find out how it was made. For reference here is an example of the music in the game.
I find the music really beautiful and captivating. Maybe it’s the nostalgia but I find the compositions really fitting for the game. And I want to learn what they used. Especially for the sound effects, I think they almost could fit in the game we are working on. For the machine sounds or ambient sounds, they sound a bit crushed or low bit rate. See below for examples.
I searched online but only seemed to find research about the current Runescape version, not the older version. Or any information was mainly just stating it was midi. I found a Reddit post that Ian Taylor replied to explaining how he made the audio.

I also managed to find a tweet where Ian shows the original synthesizer they created to make all the Runescape sound effects.

I also found another Reddit post that explains the Runescape 2 sound effects were mainly additive synthesis using this above synthesis engine they created for their making their own personal sounds.

I want to attempt to explore additive synthesis and see what I can create. Explore the sound design elements and create some sound effects of machinery for the child being created and the ambience of the factor in the game.
