Soundscope Free audio analysis tools
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.
