For a lot of listeners, this audio was pretty much indistinguishable from the source of the audio. ATRAC1 can be used for mono audio, doubling recording time. ATRAC technology was used with Sony's MiniDisc format which offered digital audio that was indistinguishable from CD-Audio on much smaller physical media. Further evolution of the ATRAC system say its use in digital downloads and Sony Walkman-brand audio players (in fact, Sony's first digital audio devices didn't support the much more common MP3 format.)
Sony is not the only manufacturer to support ATRAC in its products; Sharp and Panasonic are two examples of others who implemented the technology into their products.
