## 🚀 Quick Install
### Interactive Install (Recommended)
Our new interactive installer guides you through setup with intelligent hardware detection:
```bash
curl -fsSL raw.githubusercontent.com/jatinkrmalik/vocalinux/v0.6.3-beta/install.sh -o /tmp/vl.sh && bash /tmp/vl.sh
```
**Choose your engine:**
1. **whisper.cpp** ⭐ (Recommended) - Fast, works with any GPU via Vulkan
2. **Whisper** (OpenAI) - PyTorch-based, NVIDIA GPU only
3. **VOSK** - Lightweight, works on older systems
The installer will:
- **Auto-detect your hardware** (GPU, RAM, Vulkan support)
- **Recommend the best engine** for your system
- **Download the appropriate model** (~39MB for whisper.cpp tiny)
- **Install in ~1-2 minutes** (vs 5-10 min with old Whisper)
> **Note**: Installs v0.6.3-beta. For other versions, check [GitHub Releases](https://github.com/jatinkrmalik/vocalinux/releases).
### Installation Options
**Default (whisper.cpp - recommended):**
```bash
curl -fsSL raw.githubusercontent.com/jatinkrmalik/vocalinux/v0.6.3-beta/install.sh -o /tmp/vl.sh && bash /tmp/vl.sh
```
Fastest installation (~1-2 min), universal GPU support via Vulkan.
**Whisper (OpenAI) - if you prefer PyTorch:**
```bash
curl -fsSL raw.githubusercontent.com/jatinkrmalik/vocalinux/v0.6.3-beta/install.sh -o /tmp/vl.sh && bash /tmp/vl.sh --engine=whisper
```
NVIDIA GPU only (~5-10 min, downloads PyTorch + CUDA).
**VOSK only - for low-RAM systems:**
```bash
curl -fsSL raw.githubusercontent.com/jatinkrmalik/vocalinux/v0.6.3-beta/install.sh -o /tmp/vl.sh && bash /tmp/vl.sh --engine=vosk
```
Lightweight option (~40MB), works on systems with 4GB RAM.
### Alternative: Install from Source
```bash
# Clone the repository
git clone https://github.com/jatinkrmalik/vocalinux.git
cd vocalinux
# Run the installer (will prompt for Whisper)
./install.sh
# Or with Whisper support
./install.sh --with-whisper
```
The installer handles everything: system dependencies, Python environment, speech models, and desktop integration.
### 🌙 Nightly Releases (Bleeding Edge)
For developers and early adopters who want to test the latest features, check out our [GitHub Releases page](https://github.com/jatinkrmalik/vocalinux/releases) which includes both beta and nightly builds.
> **⚠️ Warning**: Nightly releases contain the absolute latest code and may be unstable. For production use, we recommend using the latest beta release.
Nightly builds are automatically generated from the `main` branch every day. They include all merged changes but haven't undergone the same testing as beta releases.
**Release Channels:**
- **Beta** (Recommended) — Tested pre-releases with known features
- **Nightly** — Untested bleeding edge with latest commits
### After Installation
```bash
# If ~/.local/bin is in your PATH (recommended):
vocalinux
# Or activate the virtual environment first:
source ~/.local/bin/activate-vocalinux.sh
vocalinux
# Or run directly:
~/.local/share/vocalinux/venv/bin/vocalinux
```
Or launch it from your application menu!

## 🔊 Sound Customization
Vocalinux uses smooth, pleasant gliding tones for audio feedback:
- **Start**: Ascending F4→A4 (0.6s) - positive, uplifting
- **Stop**: Descending A4→F4 (0.6s) - resolves completion
- **Error**: Lower descending E4→C4 (0.7s) - gentle but noticeable
All sounds use pure sine waves with smoothstep interpolation for buttery smooth pitch transitions - perfect for headphone use!
### Regenerate Sounds
To modify or regenerate the notification sounds:
```bash
python scripts/generate_sounds.py
```
This script generates all three sounds using the same smooth glide algorithm. You can edit the frequencies, durations, and amplitudes in the script to customize the sounds to your preference.
