This is a simple implementation of "turning code execution into audio". With a history back into the mid 20th century, programmers and operators historically would use these type of sounds coming from a computer to detect (via sound!) a program hang (i.e. a running program would have constantly changing sounds, but a hung program gets stuck on one tone indefinitely).
An example of a computer system doing this "code to tones" trick can be viewed here.
You can "cut to the chase" and hear what these 'Hello, World!' programs "sound like" via this YouTube playlist.
NOTE that make-waves.sh was developed under Ubuntu 20.04 x64, but should work on any system with syscall and a modern bash interpreter. I probably shouldn't have done this as a bash script, but, well, here we are... :)
This project currently contains 8 versions of "Hello, World!" to showcase the make-waves.sh script ability (but you can absolutely use make-waves.sh to create tones from YOUR progams, too!):
- C
- go
- rust
- java
- python
- ruby
- perl
- bash
You can use make to build the compiled versions, and make clean to remove compiled artifacts. NOTE that you'll need to have installed the required build tools and script interpreters to run each version of these.
You can create the associated WAVE file for a program (or several) easily:
./make_waves <program name> [<program name> ...]
Examples:
WAVE file for C's "Hello, World!" (results in hellow-c.wav):
./make-waves.sh ./hellow-c
WAVE file for go's "Hello, World!" (results in hellow-go.wav):
./make-waves.sh ./hellow-go
WAVE file for rust's "Hello, World!" (results in hellow-rust.wav):
./make-waves.sh ./hellow-rs
WAVE file for java's "Hello, World!" (results in hellow-java.wav):
./make-waves.sh ./hellow-java
WAVE file for python's "Hello, World!" (results in hellow.py.wav):
./make-waves.sh ./hellow.py
WAVE file for ruby's "Hello, World!" (results in hellow.rb.wav):
./make-waves.sh ./hellow.rb
WAVE file for perl's "Hello, World!" (results in hellow.pl.wav):
./make-waves.sh ./hellow.pl
WAVE file for bash's "Hello, World!" (results in hellow.sh.wav):
./make-waves.sh ./hellow.sh
You can use make waves to create ALL of the WAVE files (might take a minute), and you can use make clobber to remove compiled artifacts AND all WAVE files.
- make computation algorithms and WAVE file specifics more easily "tweakable" in
make-waves.sh - base tones on actual instruction execution (although, using SYSCALLs makes this software eaiser for more folks to use)
