craftos2 VS AUKit

My main passion right now is working with the ComputerCraft mod for Minecraft, which adds a flexible Lua-based fantasy terminal to the game. I'm most known for CraftOS-PC, a cross-platform desktop and mobile C++ app which recreates the ComputerCraft environment outside Minecraft. I'm currently working on writing an operating system for it called Phoenix, which aims to implement a full-fledged POSIX/Linux-like environment all in Lua.

Finally, (self plug) I make a Lua terminal program, CraftOS-PC, that has an API for audio playback built-in, as well as a very robust library for audio loading, generation, modification & playback, and even a sound generator plugin to handle tones for you, so if all you want to do is play around with learning how low-level audio generation and mixing works, I highly recommend it - working on this stuff taught me everything I've learned about the mechanics of sound.

My AUKit library for CC:T includes a bunch of functions for loading, manipulating, and playing audio, with support for PCM, DFPWM, WAV, AIFF, AU, and FLAC in any sample rate or data format. You might be able to find what you need here. If you really want those frequencies, you'll need to find an FFT library for Lua; but I don't recommend doing this in plain Lua because it'll be extremely slow. It takes about a minute to run an FFT on a 4 minute song using LuaJIT, and for CC's Lua, it would probably take over an hour.

What file are you trying to play? CC only allows playing .dfpwm and some wav files without extra libraries. Try running `speaker ` program where url is link to file you are trying to play on speaker. If that don't work you might need to use external CC library to play your sound. Try https://github.com/MCJack123/AUKit to see if that don't help.

If you don't want to convert files to such specific formats, you can use AUKit's austream, which allows you to play any type of WAV, DFPWM, AIFF, AU, or FLAC file. Just download the aukit.lua and austream.lua files to the computer, and then use austream to play it.

It's using u/JackMacWindowsLinux's Aukit.
