SoundScope
A browser sound lab: drop in an audio file and get waveform, spectrogram, spectrum, stereo field, metadata and detected signal events — plus a live microphone view.
Signal analysis for audio, in a private browser workspace. Upload WAV, MP3, FLAC, AIFF or most anything FFmpeg can decode and get a stereo waveform, a spectrogram and waterfall, the averaged frequency spectrum, a stereo-field phase scope, channel levels and the container metadata FFprobe can extract, alongside detected transients, dominant frequencies and repetitions. Pin markers, trim, filter and clean up without touching the original — every render is a new file. A pattern library compares spectral signatures across 32 bands by cosine similarity, and detection models are transparent frequency rules you build and run yourself; no pretrained semantic AI, and it says so rather than claiming to identify a sound. Live input shows your microphone in real time and uploads only what you choose to save. FFmpeg for decoding, NumPy and SciPy for the analysis.
