Week 1 Forum - Electronics, Instrument Building and Improvisation

This week Christian introduced us to what we were going to do this semester in Music Technology Forum. I think the expectations of us are really high this semester. It's a big ask for students with no previous knowledge in electrical engineering to build something like this:

I wouldn't have the heart to do this to my Super Nintendo. . .


[2]
Circuit Bending Improvisation. . .


In forum this week we look at the Victorian Synth. Basically this is the process of connection a speaker to a battery and creating sounds by experimenting with the positive and negative terminals. I also used rice, tacks and jilla mints on top of the speakers to create different sounds. Overall it was an interesting and tasty experience.

Victorian Synth experimentation. . .


My main problem this week was working out the order of connecting devices. I also found it difficult to get any kind of varying sound effects. I found my speakers made the same noise regardless of the position they were in.[3]

CC2 Week 1 - Music & Sound Processing


I found the task this week generally okay. My main challenges was getting the line object to work properly. For most of the time that I was building the patch, I still heard a click when I turned the sound off.

I have some screen shots and my patches below.

AA2 Week 1 – Introduction to Game Audio

Super Mario Brothers (1985) Nintendo

[1]


Super Mario Brothers, in my opinion, is the most popular and influential video games of all time. This game has continually had new versions made for new platforms and also had older versions now available using emulators. E.g. the original Super Mario World (on SNES) is now available on the Gameboy Advanced and Nintendo DS.[1]

Nintendo first released Super Mario on the Nintendo Entertainment System (NES) in 1985. The NES had a total of five sounds channels. These included:

- 2 x pulse wave channels with a volume resolution of 16 (Supported frequencies between 54Hz & 28kHz).

- 1 x fixed volume triangle wave (supporting frequencies between 27Hz & 56kHz)

- 1 x white noise generator (16 pre-programmed frequencies) with a volume resolution of 16 (two modes by adjusting inputs on a linear feedback shift register)

- 1 x delta pulse-width modulation channel (6 bit range) with 16 pre-programmed sample rates between 4.2kHz & 33.5kHz. This channel was also capable of playing standard pulse-code modulation (PCM) by writing individual 7-bit values at timed intervals

CPU - 8-bit / 1.79MHz
Memory - 2kB onboard RAM

Game cartridges have their own RAM, which will increase the amount of memory. The NES supports a total of 48kB of RAM.[2]


[1]The final showdown. . .


So now that you have an idea of the specs of the old school Nintendo it is easier to understand the quality and possibility of the sound FX and music. The NES was an 8-bit video game console meaning that the sound quality was quite inferior to today’s’ standards. 8-bit sound FX are not such a problem as any kind of distortion could add to the sound. Sounds like Mario jumping, power up FX, dieing etc. do not need to be of high quality.

The music in Super Mario Brothers, written by Koji Kondo, is played in such a way that can be repeated and not drive the gamer insane. A lot of the music in other levels is a variant of the original theme. Kondo has received some criticism for this.[3]

[3]Koji has a lot to smile about. He is still producing video game music today. . .


I think the music quality was good for that era. In 1985 digital audio in general was very new and the storage of digital sound and music was difficult. I think the music for Super Mario Brothers and the NES in general were revolutionary of that time.[4]

I thought I'd leave a movie of me playing the game. . .
