Thesia: Multi-track Spectrogram / Waveform Viewer

This project is in a very early stage.

Design Draft

Setup

macOS, Linux

1. Install Rust

2. Install node.js v16.20.2 ~ v21 (The most recent version tested: v21.6.1)

     nvm install 21.6.1
     nvm use 21.6.1

3. Install napi-rs/cli and dependencies

   # clone thesia repo & cd to the directory
   npm install -g @napi-rs/cli
   npm run build:backend
   npm install

Windows

1. Install Rust

2. Install vcpkg and openblas

   git clone https://github.com/microsoft/vcpkg
   .\vcpkg\bootstrap-vcpkg.bat
   .\vcpkg\vcpkg integrate install
   vcpkg install openblas --triplet x64-windows-static

3. Install nvm-windows (using a GUI installer)

4. Install node.js v16.20.2 ~ v21 (The most recent version tested: v21.6.1)

   # clone thesia repo & cd to the directory
   npm install -g @napi-rs/cli
   npm run build:backend
   npm install

Run in Dev Mode

npm run start

packaging into an executable binary

npm run package

Plan

• dB colorbar
• Hi-DPI display support
• time / frequency info on mouse hover
• waveform amplitude zoom in/out slider
• selecting spectrogram mode / waveform mode
• configurable STFT parameters
• peak / RMS / LUFS / LKFS level calculator
• volume normalization
• Audio Player
• STFT parameters preset
• pitch / formant tracker
• Adaptive STFT (sth like iZotope RX Editor)
