Soundscope
Professional grade audio analysis—spectrogram, LUFS, stereo width, key, and BPM. Runs in your browser or download for Mac and Windows.
Features
Spectrogram
Visualize frequency content in a high-resolution and resizable interface. Supports mel, log, or linear scaling with adjustable FFT size and dynamic-range.
Loudness Meter
Measure integrated loudness (LUFS), short-term max, true peak, RMS, dynamics, and loudness range—compliant with the ITU-R BS.1770 / EBU R128 standard.
Stereo Image
Calculate stereo width, mid/side balance, and left/right correlation; visualized over time.
Key Detection
Detect key with confidence scores for both root and mode. Ambiguous results show the most likely candidates.
BPM Detection
Detect tempo quickly with a confidence score so you can lock in BPM fast. Includes precise note timings in milliseconds.
Formats & Performance
Supports one-shots and full songs in WAV, MP3, FLAC, OGG, AAC, AIFF, OPUS, M4A. Export visualizations as a PNG.
