What is DSEE HX audio technology?

While lossy music files (like MP3s) are great for saving space on your device, they are missing vital information from the song’s original recording file. On the other hand, High-Resolution Audio file formats (such as FLAC and WAV) are created with lossless compression that allows the original data from a recording to be reconstructed almost perfectly by a class of algorithms. DSEE HX™ Technology lies somewhere in between. Here’s how:

Sony DSEE HX™ software upscales your existing sound source (those lossy MP3s or AACs) to near high-resolution sound quality. This means that the technology injects more life into your music by upscaling compressed files. So it restores the subtleties of the original song recording.
