Lofi Converter

Lofi (low fidelity) imitates the imperfections of old equipment: a slightly slower, lower-pitched tempo, dull highs from worn tape or cheap speakers, the crackle and hiss of vinyl, the slow pitch wobble of a stretched cassette (wow and flutter), reduced bit depth, and a small, soft room. Layering several of these subtly is what gives the cosy, nostalgic sound.

Yes, on purpose. Like a turntable played at a lower speed, the song becomes slower and deeper together: the pitch change in semitones is 12 × log2(speed), so 0.88× lowers it by about 2.2 semitones and makes it about 14% longer. Use 1.00× to keep the original speed and pitch.

Bitcrush reduces the number of levels each sample can take, from the normal 16-bit down to about 6-bit at 100%. Low settings add a gritty, sampler-like texture; high settings sound harsh and noisy. Many lofi producers keep it under 30%.

No. Both are generated by the tool from random noise: crackle is a mix of quiet surface hiss and short random clicks and pops, rain is filtered pink and brown noise with tiny droplet sounds. They loop seamlessly under the song and are mixed after the filters, so they stay crisp.

Changing a song's sound does not change who owns it. You can freely process your own music or tracks with a license that allows remixes, but uploading a lofi version of someone else's copyrighted song needs the rights holder's permission.

Slowing down stretches the song by 1 ÷ speed, and the reverb tail adds about a second at the end. A 3:00 song at 0.88× becomes about 3:25.
