From the first file to the first playback

Choose a method and learn how geometry, material, and fabrication settings shape the result. The converter runs in your browser with audio processing on the server.

3D-printed records

Convert a WAV into an STL record. Compare resin and FDM grooves, choose a preset, and prepare a short playback test.

Laser-cut records

Create record grooves from WAV audio for LightBurn, xTool, and Glowforge. Learn about kerf, path splitting, layers, and test cuts.

Bambu printing settings

Starting settings for printing record grooves with 0.4 mm and 0.2 mm nozzles: pitch, layer height, orientation, and troubleshooting.

How grooves work

Understand how Make a Record encodes WAV audio in a spiral, and how RPM, groove pitch, sample rate, and modulation affect the result.

What can I make?

Export DXF for LightBurn, SVG for xTool P2S or Glowforge, and STL for resin or Bambu/FDM printers. The seven presets are starting geometries; verify the dimensions and test a short clip on your equipment. A compatible cutter or printer is required to fabricate the record.

Will it sound like a commercial record?

Expect experimental, lo-fi audio. The download includes a preview of the signal encoded into the groove. Real playback also depends on your machine, material, stylus, and disc flatness. Read more about the method and its limitations.
