What is a .SPX file?

An SPX file is a type of audio file that uses the Ogg Vorbis container format. This format is special because it can hold different kinds of multimedia, but in the case of an SPX file, it specifically holds audio that has been compressed using the Speex codec. This codec is great for voice audio because it can compress voices at different quality levels, from 2 to 44 kbps, which helps save space without losing too much quality. It can handle different frequencies of sound, so whether the sound was recorded at a low, medium, or high quality, the SPX file can manage it all in one stream.

SPX files are often used to store voice recordings, like those you might hear in video games or podcasts. They can also hold other types of audio, such as music or sound effects, making them quite versatile.

To open an SPX file, you can use several different programs. One of the most popular is the VideoLAN VLC media player, which is available for free and can handle many types of audio and video files. Other programs that can open SPX files include File Viewer Plus, which you can download from the Microsoft store, foobar2000, and CoolUtils Total Audio Converter. These tools help you play or convert SPX files into other formats if needed.

The technology behind SPX files, developed by Xiph.Org, includes features like noise suppression, which reduces background noise, echo cancellation to avoid sound repeats, and variable bitrate encoding, which adjusts the file's data rate based on the complexity of the audio. This makes SPX files a smart choice for various audio applications, especially where clear voice audio is needed.
