maybe "sox-bible is bit of overstatement, but oh well..."

SOX BIBLE by INFU

Here you will find:

many links to various fantastic sox resources (each one was also archived by "archive.org" in case some links fail!)
Plenty commands or small scripts I assembled
Focus on Wavetable Synthesis!

(It might not be comprehensive sox place-to-go, but surely you'll find it resourceful!)

sox is a robust command line audio studio for pretty much any kind of job - Think of it like "Text-based Audacity"!
Easily convert your audio from one format to another - no problem!
If you need extra precision, you have dozens of parameters to tweak!
While not as user-friendly or intuitive like apps with graphic interface, sox can make up for it with it's speed and precision.. if you know how to achieve it ^^;

Funny enough, sox a reason why I got into terminal/programming stuff at all!

To get most out of it, we need not only to learn sox, but also some scripting language, like Python, Bash, or Windows Batch!
Programmer or not, if you're using terminal then some Bash knowledge will do you so good!

in this article I'll stick to Bash (that's available in pretty much every Linux system, and on Windows available through "Git for Windows" / "WSL"!)

There aren't many examples online that take full advantage of all features...
Heck - some sox effects feel barely talked about even by manual itself!*
I got some links with sox guides and resources below, each containing various commands and tricks!

One example of neglected powerful features IMO is "synth"!

sox has built-in synthesizer, and while took me some time to understand it well, it was worth it as it's pretty cool!
You can generate up to 10 waveforms, mix them together in couple ways, slap some effects on them, which got me thinking...
I can create my own wavetable! if you don't know what it is, let me try explain it without nerding out about whole *"Art and History of Wavetables" XD

Wavetable is set of various tiny audio waveforms, grouped together as one small audio file:
It's like a soundfont, with plenty instruments of varied timbre each, just with total limit of 2 seconds, taking no more than half a megabyte.. Wavetables can turn your basic Sampler into fully featured Synthesizer!
I created a bunch of various helpful scripts to make those wavetables, some involve sox in some way, some others include other tools.
Enjoy!
