Introduced in 2006, [1] DSEE is included in Sony's digital Walkman products and freeware SonicStage CP (version 4.2 or higher), x-app, and Music Center for PC.In operation, it analyzes irreversibly compressed music files such as MP3, ATRAC3, AAC, and WMA, and performs predictive calculations to compensate for high-frequency sounds lost due to compression, thereby improving sound quality.
In 1957 Willard Meeker developed a working model of active noise control applied to a circumaural earmuff. This headset had an active attenuation bandwidth of approximately 50–500 Hz, with a maximum attenuation of approximately 20 dB. [3] By the late 1980s the first commercially available active noise reduction headsets became available.
