2 unified studios · 100% client-side execution · Zero uploads · No sign-up
Trim waveforms, analyze loudness in dBFS, synthesize tones or pink/brown noise, extract exact video frames, build timestamped storyboards, and demux WAV audio locally.
Audio & Waveform Studio
Decode and trim audio on an interactive waveform, apply fades and peak normalization, export 16-bit PCM WAV, inspect FFT spectrum & dBFS loudness, synthesize tones/noise, and run a precision metronome.
Video Frame & Media Studio
Scrub local MP4/WebM videos to capture full-resolution PNG/WebP frames, build timestamped storyboard contact sheets, extract lossless WAV audio tracks, and calculate bitrates.
Common workflows in Audio & Video Studios
Waveform trimming & 16-bit PCM WAV export
Decode MP3, WAV, OGG, M4A, or FLAC locally via Web Audio API, set millisecond cut markers with smooth fades, normalize peaks, and save lossless WAV.
Reference tones, noise & precision metronome
Synthesize sine/square/saw/triangle tones or filtered Pink/Brown noise, run a zero-drift Web Audio metronome, and calculate BPM delay times.
Video stills, contact sheets & audio extraction
Step through local MP4/WebM footage frame-by-frame, generate composite timestamped contact sheets, or extract the audio track to .wav.
