LiveCore

A hardcore livecoding system for realtime audio synth in the spirit of Sound Garden.
WIP with
Work with the garage door up ethos.

Influences

Dependencies

On macOS:

  1. $ brew install fswatch libsndfile
  2. or
  3. $ port install fswatch libsndfile

For Nim try choosenim.

There is also shell.nix for Nix users, which is the installation method I use and test against.

Configuration

Sample rate and channels count is hardcoded to 48000 and 2 respectively.
If your device requires different values, edit src/dsp/frame.nim.

Session workflow

NB: you need to run all the mentioned scripts from the repo root.

  • Checkout starting point. For a fresh session the main branch is a good choice.
  • Make sure that the git tree is clean, as this script will be committing your
    changes as you make them.
  • Start server with ./start-server
  • Run ./start-session with a session name as an argument.
    It must be valid as a part of git branch name as the script will prefix it with
    session/ and checkout this branch.
  • If the session with such name exists it will be resumed.
  • Make changes in src/session.nim and save file to compile and send to the server.
  • After every successful compilation there will be a commit.
  • Ctrl-C this script to stop and switch back to the starting point.
  • The system is ready for the next session!

Render

To render a specific session duration in a non-interactive mode to a file:

  1. $ ./render <duration in seconds> <path/to/output.wav>

Examples

Peek into src/session.nim in session/* branches.

FAQ

Why Nim?

C-like freedom, performance and fast compilation with heaps of syntactic sugar.
clive very much aligns with the vision I wanted to implement and I’d just port
clive to macOS if only C was terser. When I’m jamming I want the code to be
clean, concise and close to my intention, all other necessary trade-offs
considered.

Does it run on Windows/Linux?

Maybe. Please try and let me know! I strive to write the code in a
platform-independent way but I test it only on macOS.

Why snake_case procs and vars?

Purely irrational, æsthetic choice. CamelCase seems to be prevalent in the Nim
ecosystem, and majority of the code I write/read in other languages is camelCase
too. However, I enjoy the most writing/reading OCaml and Rust in the regard of
that particular convention, and I’m glad that Nim’s compiler doesn’t actually
care, so I went with underscores.
