SPX File

File extension .SPX
CategoryAudio File
DescriptionSPX (Speex) is an open-source CELP-based speech codec format intended for compressing speech at bitrates between 2 and 44 kbps. The .SPX extension has a number of advanced features, which ensure noise- and echo reduction, stereo encoding, integration of several sample rates within a particular bitstream, etc. Although SPX is patent-free, it is not widely supported by popular audio players. For this reason, most users prefer to convert SPX files to WAV or MP3.

MP3 File

File extension .MP3
CategoryAudio File
DescriptionMP3 is the most popular audio file type based on MPEG-1 Layer III compression. Its lossy algorithm was developed in 1991. MP3 codes the sound almost with the same quality, as CD (16-bit stereo), providing compression in size 1 to 10 from the original WAF or AIFF tracks. The quality of MP3 seriously depends on the bitrate. It can be 128 - 256 kbps. Higher bitrates are also supported, but they seriously increase the file size. It is supported by all modern hard- and software players.
