Editing ATRAC (section)

== Performance ==
ATRAC algorithms were developed in close cooperation with [[Integrated circuit#LSI|LSI]] integrated circuit development engineers within Sony in order to deliver a product that could encode at high speeds and with minimal power consumption.<ref>{{Cite web|url=https://www.sony.net/Products/ATRAC3/special/developers01.html|title=Sony Global - ATRAC - Developer's Interview|website=www.sony.net}}</ref> This contrasts with other codecs developed on computers without regard for the constraints of portable hardware. This is reflected in the design of the ATRAC codecs, which emphasize processing smaller groups of samples at a time to save memory at the cost of compression efficiency and additional multiplies. These trade-offs are logical for [[Digital signal processor|DSP]] systems, where memory was often at a premium compared to multiplier performance.

Sony [[Walkman]]s offer better battery life when playing ATRAC files than when playing [[MP3]] files. However, as Sony only pushed ATRAC compatibility in [[Sony Ericsson]] Walkman series phones in the Japanese market, it is not supported in [[GSM]]/[[UMTS]] market phones. Sony's [[Xplod]] series of car audio CD players support [[ATRAC CD]]s. Minidiscs with ATRAC format songs have, in the past, been supported on Eclipse brand car stereos.
