Audio HLS streaming
i personally use github.com/faiface/beep for most of my audio playing.

Sine wave generator using Golang
We will be using beep go package to process audio signals and playback sounds. Beep uses oto under the hood for audio playback.
-
Audio library that can play as many file formats as possible?
https://github.com/faiface/beep is handy and I've used it for a player. You could extend further to add support for decoding other file types it didn't do (it currentlu does MP3, WAV , FLAC, OGG)

Wrote a Chip8 emulator to teach myself Go, it is one of the most comfortable languages I have ever used.
For learning Go, A Tour of Go, and tutorials from libraries I used (Pixel and Beep), as well as a lot of Googleing.
-
Any "simple" projects with particularly well-written and/or well-documented code for a beginner to look through?
Shamelessly: https://github.com/faiface/beep
- Any good git repos made by a single dev?

How to read data from mp3 audio file in golang?
I just want the format of the sample data, so that I can process it. Also studying this: faiface/beep...

Stream YT Audio from Go?
You can use beep for playing the audio and use a wrapper of youtube-dl for getting the audio urls.

Lag Is Never Where You Want It... Or Don't Want It
Reading ebiten docs and source code they very clearly state that writing RGBA bytes to an image is slow, and shouldn't really be done every frame, at least many times per frame. This is where I thought my performance was being lost, and it sent me looking for answers for ages. Turns out, I was wrong and right.

Making Games in Go for Absolute Beginners
I love Go, yet I've never thought of it as a language with usable game engines. I'm extremely happy to find I was very wrong about that!
I'm woefully behind the curve on compiling to WASM, though, and I've yet to experiment much with tinygo so I have no idea how far I would get in creating a game people could enjoy in a browser without having to download a big bundle of assets. It's reassuring to see WASM mentioned explicitly as a compilation target [1] by Ebitengine though.

Ho did/do you remove cgo?
For other OSes, see https://github.com/hajimehoshi/ebiten/issues/1162

Is there a love2d for c++?
What about learning Go with Ebiten? Or Rust with Bevy?
-
What would be the closest thing to Unity/Unreal C#/C++ for Go to create games/animations/visual work?
Actually, there is a game engine in Go. Ebiten(gine) is actually really popular and has already been used for a few games in production

Mac + opengl
I noticed a similar issue when I got my MBP with the framebuffer not matching the window size and this has to do with the DPI settings. This GitHub link helped me understand the issue better and I hope it can be of assistance to you https://github.com/hajimehoshi/ebiten/pull/1811

crten - a small tool to view your pixel art with a CRT screen effect
This program also demonstrates how great Ebitengine is and how you can port GLSL shaders to it almost 1 to 1.
