Rendered version of the Official SigMF Logo

The Official SigMF Logo

The provided SigMF pair sigmf_logo.sigmf-meta and sigmf_logo.sigmf-data represent the stereo audio that is the official SigMF logo.

The intent of these files is to both serve as a nice visual and an exemplar metadata to be used as a reference. The png is just a simplified view of the logo as rendered on an XY-oscilloscope per the below gist.

Additional Versions

The full logo archive contains a variety of versions of the logo for multiple use-cases.

  • sigmf_logo_fullband is the unfiltered logo at 192 KHz sample rate.
  • logo_*.wav are audio files for playback without converstion from SigMF.
  • logo_manifold.stl is a logo suitable for 3d printing.
  • logo_*.mp4 are XY-oscilloscope videos rendered from the SigMF logo.
  • logo-scope.* are vectors & images rendered directly from the SigMF dataset using this gist.
  • logo-*.svg are various vector versions of the logo.
  • logo-icon-*.png are various icons for folders or discord in multiple sizes.

How was this created?

The SigMF logo was created with the following steps:

  1. Initial render in Blender with as simple geometry as possible. The stl is a very simplified and tweaked version of the Eurostile font.
  2. A timeline was created with OsciStudio with various modulated artifacts over a 6 second period.
  3. The lower 48KHz version was then lowpass filtered and adjusted for -14 LUFS in Audacity per the EBU R 128 loudness spec.
  4. Original metadata was added with the SigMF Python module.
