Interactive Acoustic Lab
Explore how raw audio transforms into rich acoustic spaces inside your browser. Inspect the live DSP pipeline, calculate speed and pitch math, simulate 8D binaural orbits, and understand true-peak export limiting.
Audify runs 100% inside your browser using the HTML5 Web Audio API. Click any processing node below to inspect its mathematical transfer function, buffer lifecycle, and acoustic parameters.
Modulates playback speed and pitch. In Varispeed mode, changing speed naturally alters musical pitch (like vinyl or tape). For independent pitch shifting, polyphase sinc interpolation shifts semitones while preserving time.
For Slowed + Reverb, rate is set to 0.85× (-2.83 semitones). For Nightcore, rate is pushed to 1.35× alongside a +3.0 semitone lift for an energetic +7.87 semitones total transposition.
Experiment with tempo and pitch multipliers. Learn how the viral Slowed + Reverb and Nightcore aesthetics derive their exact acoustic formulas.
8D audio creates the illusion of a physical band walking in circles around you. Watch how Interaural Time Difference (ITD) and Level Difference (ILD) guide the stereo field.
Understand how low-shelf and peaking filters alter frequency energy. Watch how boosting bass reduces digital headroom and triggers the −0.3 dBFS true-peak limiter.
Even when extreme +15 dB bass boost is applied, Audify's look-ahead limiter prevents inter-sample digital clipping by clamping instantaneous peaks to −0.3 dBFS.
Reverberation is the acoustic persistence of sound after its source stops. Inspect the synthetic impulse response curves that Audify convolves with your audio.
Choose the optimal export encoding. Understand the mathematical tradeoffs between uncompressed linear PCM and lossy psychoacoustic MP3 encoding.
Best For: Music production, master archival, video editing sync. All exports from Audify pass through our look-ahead true-peak limiter calibrated to −0.3 dBFS to prevent inter-sample clipping on consumer audio converters.
A frictionless, four-step workflow from audio import to master download.
Drag and drop any MP3, WAV, OGG, FLAC, or AAC up to 10 MB. Files are decoded strictly into your browser's RAM.
Choose from 36 acoustic treatments or customize speed, pitch, biquad filters, and stereo panning sliders.
Listen to instant zero-latency previews with real-time waveform navigation and A/B bypass comparison.
Export bit-accurate WAV (16/24/32-bit float) or 320k MP3 with −0.3 dBFS true-peak look-ahead limiter protection.
Put this theory into practice. Load your audio track into Audify Studio and audition every acoustic preset in real time with zero server wait times.
