In this series, I'm going to build Oxygen, a voice journal and audio analysis toolkit for people who want to change the way their voice comes across. In the first episode, we're making a CLI clone of the "Voice Memos" app on Apple platforms — it lets you record and play back audio clips. In the next few videos, I'll talk about audio compression/encoding/decoding and make our CLI app a little more fully featured. Later on, I will also be building a UI and diving into audio processing and analysis.
Today's code: https://github.com/emilyskidsister/ox...
Setup: I use neovim with coc.nvim and coc-rust-analyzer, which turn neovim into an IDE. The theme is fairyfloss.vim, based on Sailor Mercury's theme. My full setup is available at https://github.com/emilyskidsister/do.... Other tools shown in this video are alacritty, tmux, and fish.
