Thesia: Multi-track Spectrogram / Waveform Viewer

This project is in a very early stage.

Design Draft

Build Setup

1. Install prerequisites
   • Common
     • Rust
     • node.js v16.20.2 ~ v21
       • The most recent version tested: v21.6.1
   • Windows
     • vcpkg & OpenbLAS

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

   • Linux
     • ALSA
       • For Debian/Ubuntu: sudo apt install libasound2-dev
2. Install npm packages & build

   # 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

The target binary is under release/build/<os>/thesia.app.

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)
