What is an SPX file?

An SPX file is an audio file saved in the Ogg Vorbis container format and encoded with the Speex Audio codec. It supports voice compression at 2 to 44 kbps and supports 8 kHz, 16 kHz, and 32 kHz compression in the same bitstream. SPX files typically store voice recordings for video games and podcasts, but may also store other audio content, such as music or sound effects.

The Ogg Vorbis Speex format is developed by Xiph.Org. The Ogg Vorbis container format is utilized by several types of multimedia files, including .OGG and .OGX files.

In SPX files, the audio data stored in the Ogg Vorbis container is encoded with the open-source Speex codec. Speex supports intensity stereo encoding, noise suppression, echo cancellation, variable bitrate (VBR) encoding, Voice Activity Detection (VAD), and Discontinuous Transmission (DTX).

An SPX file may also be a CAM (computer-aided manufacturing) file that contains stitching instructions for creating embroideries with a Pfaff sewing machine. It stores a pattern, which may be a flower, text, image, or other design. SPX files are supported by various Pfaff sewing machines from 2010 and later.

More Information

You will most likely only encounter a Stitch Pattern SPX file if you use a Pfaff sewing machine to embroider fabric. Embroidery programs, such as BALARAD Embird, may also export patterns as SPX files. They can also be downloaded from sewing websites.

You can view and modify SPX files with an embroidery program that supports the format. Then you can place it on a USB flash drive and insert it into a Pfaff sewing machine to load and stitch the design onto a material.

NOTE: Pfaff sewing machines manufactured before 2010, like the Pfaff 7570, do not support the SPX file format.
