Top 23 Audio Open-Source Projects

Project mention: Is there a new limit on the size an mp4 video can be before it doesn't embed itself? Never used to have this issue, even when sending longer clips. | reddit.com/r/discordapp | 2022-09-23
For reference, I personally use FFmpeg for most, if not all, of my media. Maybe Premiere does something special, but all I know is that FFmpeg is reliable in a way that it's extremely transparent in what it does and how it does it, and what it does is 100% standard, nothing special ever being applied.

Project mention: Show HN: The simplest drum pattern composing algorithm I could come up with | news.ycombinator.com | 2022-09-21
If you wanna learn how to build your own drum machine in Javascript using the WebAudioAPI, here's an amazing read: "A tale of Two Clocks." (https://web.dev/audio-scheduling/). Also, check Howler.js (https://howlerjs.com/), a rock-solid library with a great community.

digital_video_introduction
A hands-on introduction to video technology: image, video, codec (av1, vp9, h265) and more (ffmpeg encoding).
Project mention: Crestron DMC-D-4K Class Tips/Things to Watch out For | reddit.com/r/CommercialAV | 2022-07-25If you want to keep digging from there, get familiar with the compression on NVX, JPEG-XS, and how it behaves. intoPIX are the upstream vendor that do some of the NVX internals and have some great resources on that here: https://www.intopix.com/jpeg-xs. For a guide on all things digital video I also highly recommend https://github.com/leandromoreira/digital_video_introduction.

Project mention: Is there a way to integrate a raspberry pi with a keyboard to do speech to text? | reddit.com/r/ErgoMechKeyboards | 2022-09-01
State-of-the-art ASR, like what you get on smartphones, has unfortunately high resource requirements. Some recent smartphone models are able to run ASR on-device, but more typically, ASR is done by sending audio to a web service. Check out the (currently experimental) Web SpeechRecognition API in a Chrome browser. Here is a demo of the API in action. For something open source, check out Kaldi ASR.

Do you still see challenges with doing WebRTC on a server? I work on https://github.com/pion/webrtc so would love to hear what could be better :)

Project mention: How would someone who is deathly broke become a serious rapper? | reddit.com/r/makinghiphop | 2022-09-15
I'm also a programmer, and what I found very exciting is : https://sonic-pi.net/

BlackHole
BlackHole is a modern macOS virtual audio driver that allows applications to pass audio to other applications with zero additional latency.
What I have is a small macOS app that takes the input from a system default device (MBP microphone) and routes it to a custom driver (think BlackHole ExistentialAudio-BlackHole). I can record the sound perfectly fine through audacity (when the app is in its recording state) ONLY when I manually select the default output device (in the Audio MIDI Setup, or sound preferences) to the BlackHole driver. What I want to achieve is to route the audio to the custom driver independently of the currently selected output device (in the settings), think Discord app and their settings panel, where you can select any output device that you want without changing the output manually in the Audio MIDI Setup, and all of the "audio passthrough" will be unaffected.

I' just installed Xcode 13 and try to run a playground that uses a package (https://github.com/AudioKit/AudioKit). To add it I'm supposd to select "File -> Add Packages...", but when I do this absolutely nothing happens. No window appears, no error message, just nothing. What could be the reason for this?
-
OpenFrameworks
openFrameworks is a community-developed cross platform toolkit for creative coding in C++.
No big secret. I'm using openFrameworks for the creation of this 2D world with a custom implementation of a very basic physics engine but there are plenty of libraries you can use to achieve something like this. The simulation is in real time (let's say capped at 60fps) and then I render a video or the frame sequence of the process. SD takes them sequentially as input images for the diffusion process.

Project mention: Any good starter guides for learning C or C++ game development | reddit.com/r/learnprogramming | 2022-09-24
www.learncpp.com and www.learnopengl.com are both great resources with a wide range of complexity. There’s a also bunch of different frameworks you could use for game development and they each have tutorials and documentation that’ll help get you started. I recommend checking out SDL (www.libsdl.org) or GLFW (www.GLFW.org) or SFML (www.sfml-dev.org). Also maybe try out Raylib (www.raylib.com). I personally use GLFW but it’s a bit more bare bones than other frameworks and may not be the best to begin with. Hope these links help!

Project mention: I made a cross-platform command-line app called maestro to play music! | reddit.com/r/Python | 2022-07-20
Uses https://github.com/cheofusi/just_playback to play sound. It's actually surprising how hard it was to find a cross-platform Python module to play sound that doesn't require an external dependency like ffmpeg. Even then, modules like https://github.com/jiaaro/pydub don't support features like seeking/scrubbing, which was a must-have for my project.
