Audio Spectrogram Analyzer
Progressive spectrogram viewer for audio and video files on Windows, with sample-accurate frequency labeling.
Overview
A WinUI 3 spectrogram viewer that analyzes audio and video sources and renders a frequency plot left to right as analysis completes. The frequency axis reflects the file's sample rate, and bundled FFmpeg keeps behavior consistent across machines without relying on a system install.
Key features
- Progressive spectrogram rendering during analysis
- Opens audio and video source files
- Sample-rate frequency axis labeling
- Bundled FFmpeg and FFprobe
- Dark WinUI 3 interface
Technical details
STFT-based spectrogram generation with progressive display. Uses bundled FFmpeg and FFprobe rather than PATH-installed tools. Portable release builds are published via GitHub Releases when available.
