Resoluna by Loudless Labs · Limited beta

AI audio upscaler for music

Give your music a fresh listen.

Upload compatible 44.1 or 48 kHz WAV or FLAC, generate an AI high-frequency extension, and download a 24-bit / 96 kHz FLAC to compare with your original.

Output is also capped at 50 MB and is typically about 3.5 times the input size. Choose a shorter or smaller source file if needed. Files are scheduled for deletion after 24 hours.

How it works

More than changing the sample rate.

Resoluna analyzes patterns in your compatible track, including its lower-frequency structure, and estimates a plausible high-frequency extension. The result is a 24-bit / 96 kHz listening version made from music you already own—an opportunity to explore a fresh perspective without needing a separate high-resolution master. The extension is a model estimate, not the original missing signal, so keep your source and decide which version you prefer.

Illustrative spectrum: charcoal bars show source content at lower frequencies; pale mint bars show the estimated high-frequency extension.

Illustrative concepts only—not prototype output or measurements.

Step 01

Choose a compatible file

Start with music in WAV or FLAC at 44.1 or 48 kHz.

Step 02

Generate an estimated extension

The model estimates additional high-frequency content from the input audio.

Step 03

Listen and inspect

Download the 24-bit / 96 kHz FLAC and inspect the input/output spectrogram preview when available.
