0.00 / 0.00 s
Sonocode turns a sound clip of up to 10 seconds into a printable image. Audio is compressed with Opus in your browser, protected with Reed-Solomon error correction, and stored as four grey tones with a calibration row. Each audio packet carries its own checksum, so a damaged part is concealed instead of failing the whole clip.
