Signal Dashboard is a free online equalizer, compressor and limiter that runs entirely in your browser. Load an audio file (WAV, MP3, FLAC, OGG, M4A) or use your microphone and shape it with an 8-band parametric EQ (high-pass filter, low shelf, four peaking bands, high shelf and low-pass filter), a dynamics compressor with threshold, ratio, knee, attack, release and makeup gain, and a brickwall peak limiter with an output ceiling. Dozens of presets cover vocals, podcast and spoken word, acoustic and electric guitar, bass, kick, snare, drum bus, piano, synth, plus mastering chains for streaming, club, hip-hop and rock. Watch the EQ response curve over a live input and output spectrum, A/B against the raw signal, and export the processed result as a 24-bit WAV, a lossless FLAC or a 320 kbps MP3. Nothing is uploaded; all processing happens locally on your device. Part of songtools.music. See the legal disclaimer.
