# ZIM Studio - Terminal-Based Audio Studio Tools
*A [Zettelkasten](https://en.wikipedia.org/wiki/Zettelkasten) Information System for Music with Integrated Audio Player*
_Implemented in [Rust](https://www.rust-lang.org) and [Ratatui](https://ratatui.rs) with optional [nvim plugin](https://github.com/navicore/zim-studio-nvim) support._
ZIM Studio provides three main functions:
1. **Project Management**: Initialize a project structure of directories and placeholder README.md files
2. **Metadata System**: Generate searchable sidecar files for all audio media
3. **Audio Player**: Sample browsing, auditioning, and editing with TUI interface
## ✨ More...
- **Supported Audio Formats**: `*.flac` and `*.wav` (so far)
- **Enhanced Navigation**: Shift+Arrow keys for 20% jumps through long recordings
- **Smart Sidecar Cloning**: When saving selections, automatically clones source metadata with:
- Updated duration for the extracted selection
- Provenance tracking (source file, time ranges)
The sidecar format is YAML embedded in markdown, providing both structured metadata
and free-form notes. The YAML contains facts about the track while the markdown
enables long-form notes, links to inspiration, TODO checklists, etc.
See [example sidecar file](examples/sidecar-example.md) for a complete example.
The motivation for creating `zim` is twofold:
1. Maintain a workflow where DAWs are guests in my workflow rather than the
other way around.
2. I use [neovim](https://neovim.io/) and [telescope](https://github.com/nvim-telescope/telescope.nvim) for my
personal note taking and rely on no proprietary company to enable my
ability to work in software ... I wanted the same detailed note taking
independent of any vendor for my music making. I use proprietary DAWs but
am not ok living in DAWs or any vendor's closed system.
## Installation
```bash
# Install with just the project management and metadata features
cargo install zim-studio
# Install with the audio player feature included
cargo install zim-studio --features player
```
If you use neovim (untested with regular vim) you may want to try the
[nvim plugin](https://github.com/navicore/zim-studio-nvim).
## Quick Start
```bash
# Initialize ZIM with your music projects directory
zim init ~/Music/Projects
# Create a new project
zim new "My Greatest Hits"
# Creates: ~/Music/Projects/my_greatest_hits/
# Navigate to your project and add some audio files
cd ~/Music/Projects/my_greatest_hits
cp ~/Desktop/track1.flac masters/
cp ~/Desktop/track2.wav masters/
# Generate sidecar metadata files
zim update .
# Creates: masters/track1.flac.md, masters/track2.wav.md
# Edit the generated sidecar files to add your notes
$EDITOR masters/track1.flac.md
# Validate all YAML frontmatter
zim lint .
# View/edit global configuration
zim config view
zim config edit
```
## Project Structure
When you create a new project with `zim new`, it generates:
```
my_greatest_hits/
├── .gitignore # Ignores audio/video files
├── README.md # Project overview
├── masters/ # Final mastered tracks
├── mixes/ # Mix versions
├── sources/ # Raw recordings, samples
├── edits/ # Edited/comped audio
├── bounced/ # Bounced/rendered audio (stems, etc)
└── project/ # DAW project files
├── live/ # Ableton Live
├── reaper/ # Reaper
├── bitwig/ # Bitwig Studio
└── renoise/ # Renoise
```
## Sidecar Files
`zim update` generates a `.md` sidecar for each audio file with:
- **YAML frontmatter**: Structured metadata (technical specs, tags, etc.)
- **Markdown body**: Free-form notes, ideas, TODO lists
The YAML is designed to be both human-editable and scriptable for automation.
See the [example sidecar](examples/sidecar-example.md) for what this looks like in practice.
## Shell Completions
Add to your shell configuration:
```bash
# Bash (~/.bashrc)
source <(zim completions bash)
# Zsh (~/.zshrc)
source <(zim completions zsh)
# Fish (~/.config/fish/config.fish)
zim completions fish | source
# PowerShell ($PROFILE)
## Development
```bash
# Run all checks locally (matches CI)
make ci
# Individual commands
make fmt # Format code
make clippy # Run lints
make test # Run tests
make check # Check compilation
```
## Audio Player User Guide
The optional audio player provides a fast, keyboard-driven interface for browsing, auditioning, and editing audio samples directly from the terminal.
### Launching the Player
```bash
# Launch with no file (opens browser)
zim player
# Launch with a specific audio file
zim player path/to/audio.wav
```
### Main Interface
The player interface consists of:
- **Title Bar**: Shows "🎵 ZIM Player"
- **File Info & LEDs**: Current file name and stereo level indicators
- **Progress Bar**: Playback position with mark in/out indicators
- **Oscilloscope**: Real-time waveform visualization (when window is tall enough)
- **Control Hints**: Two rows of keyboard shortcuts
### Keyboard Controls
#### Playback Controls
- `[space]` - Play/Pause toggle
- `[←]` - Seek backward 5 seconds
- `[→]` - Seek forward 5 seconds
- `[Shift+←]` - Jump backward 20% (great for long recordings)
- `[Shift+→]` - Jump forward 20% (great for long recordings)
#### Mark & Loop Controls
- `[i]` - Set mark in at current position
- `[o]` - Set mark out at current position
- `[x]` - Clear all marks
- `[l]` - Toggle loop playback of marked selection
#### File Operations
- `[/]` - Open file browser
- `[s]` - Save/export (full file or marked selection)
- `[q]` - Quit player
### File Browser
The built-in file browser searches through your audio files using their sidecar `.md` metadata:
1. Press `/` to open the browser
2. Start typing to search - it searches within the markdown content of sidecar files
3. Use `[↑/↓]` to navigate results
4. Press `[Enter]` to load the selected file
5. Press `[Esc]` to close browser
**Note**: The browser displays audio files but searches their `.md` sidecar content. For example, if you have `kick.wav` with `kick.wav.md` containing "punchy 808 style", searching for "808" will find this file.
### Mark In/Out & Looping
The mark feature lets you select a portion of the audio:
1. Play the file and press `[i]` at the desired start point
2. Press `[o]` at the desired end point
3. The selection appears highlighted on the progress bar
4. Press `[l]` to loop the selection continuously
5. The time display shows selection duration in brackets: `[3.5s]`
### Save Dialog
When saving (`[s]`), the save dialog provides:
- **Directory Browser**: Navigate folders with `[↑/↓]` and `[Enter]`
- **Filename Field**: Editable with smart naming for edits
- **Tab Navigation**: Use `[Tab]` to switch between directory list and filename
- **Smart Extensions**:
- Selections always save as `.wav` (even from FLAC sources)
- Full file saves preserve original format
Example auto-generated filenames:
- First edit: `original_edit.wav`
- Subsequent edits: `original_edit_2.wav`, `original_edit_3.wav`, etc.
### LED Level Indicators
[IMAGE: Close-up of LED indicators showing different levels]
The stereo LED indicators show real-time audio levels:
- **L (Left)**: Green LEDs - dim → medium → bright → red (clipping)
- **R (Right)**: Orange LEDs - dim → medium → bright → red (clipping)
- **Symbols**: ○ (off/quiet) → ◐ (medium) → ● (loud)
### Supported Formats
- **WAV**: 8, 16, 24, and 32-bit
- **FLAC**: All bit depths (converted to 16-bit WAV when saving selections)
- **AIFF**: All bit depths with intelligent sample rate detection
### Tips & Workflow
1. **Quick Sample Chopping**: Load file → mark in/out → save = done
2. **Preview Before Save**: Use `[l]` to loop your selection before saving
3. **Rapid Browsing**: The browser remembers your search, making it fast to audition similar samples
4. **Long Recording Navigation**: Use Shift+Arrow for 20% jumps to quickly navigate through long recordings
5. **Metadata Preservation**: When saving selections, source metadata is automatically cloned with updated duration and provenance tracking
6. **No Mouse Needed**: Everything is keyboard-driven for speed
### Troubleshooting
- **No Audio**: Check system audio output settings
- **Browser Not Finding Files**: Ensure `.md` sidecar files exist (run `zim update`)
- **Visual Glitches**: Resize terminal window or restart player
