About STL Format

STL (Stereolithography) is the standard file format for 3D printing. It represents 3D surface geometry as a mesh of triangles, without color or texture information. Supported by virtually all 3D printing software and services.

About AMR Format

AMR (Adaptive Multi-Rate) is a speech audio codec optimized for voice recording. It is widely used for voice memos on mobile phones and in telecommunications for its efficient compression of human speech.
