Everything this tool gives you
Authentic Vinyl Dust Noise & 22.1kHz Vintage Resampling
Emulate the warmth and grit of classic 12-bit samplers like the SP-404 and MPC. Our DSP resamples audio to 22.1kHz and synthesizes subtle vinyl crackle and needle pops directly over the track.
- 22.1kHz linear resampling for vintage sampler warmth
- Algorithmic vinyl crackle and random needle pop textures
4665Hz Tape Roll-Off Filter & 0.94x Chill Stretch
Lo-Fi is defined by the absence of harsh high frequencies. A dedicated 4665Hz low-pass filter softens piercing highs, while a gentle 0.94x linear stretch eases the tempo and lowers the pitch for an effortless chill vibe.
- 4665Hz low-pass filter to remove harsh digital highs
- 0.94x relaxed tempo stretch with natural subtle pitch drop
