- **Spectrogram Viewer** (soniqtools.com/spectrogram/) — Visualize frequency content over time with adjustable FFT, color palettes, and dB range. Like Spek but in your browser.
- **Spectrogram Compare** (soniqtools.com/compare/) — Compare two audio files side by side. Spot upsampled, transcoded, or fake hi-res files with difference overlay.
- **Audio Metadata Viewer** (soniqtools.com/metadata/) — Read ID3 tags, cover art, codec info, and embedded metadata from any audio file.
- **Waveform Viewer** (soniqtools.com/waveform.html) — Visualize the full waveform with zoom, pan, and channel separation.
