POW-R (Psychoacoustically Optimized Wordlength Reduction) is a set of commercial dithering and noise shaping algorithms used in digital audio bit-depth reduction. Developed by a consortium of four companies – ''The POW-R Consortium'' – the algorithms were first made available in 1999 in digital audio hardware products. POW-R is now licensed for use by many companies, particularly those in the Digital Audio Workstation (DAW) arena, where it currently has significant market share. ==History== POW-R was developed between 1997 and 1998 after an unfavorable change in the licensing terms of a leading bit-depth reduction algorithm of the time prompted some of its licensees to put together a consortium to develop a viable alternative algorithm. Formed by four audio engineering companies: Lake Technology (Dolby Labs), Weiss Engineering, Millennia Media and Z-Systems, the consortium set out with the goal to create ‘the most sonically transparent dithering algorithm possible’. In 1999, the first products containing POW-R were released by consortium companies.〔 Other companies became interested in using POW-R in their products, and the algorithms are now licensed to a number of leading DAW vendors including Apple Computer, Avid-Digidesign, Sonic Studio, Cakewalk Sonar,〔(Review of Sonar 4 )〕 Merging Technologies,〔( Merging Technologies press release )〕 Ableton,〔(Ableton ‘What’s new’ )〕 Magix / Sequoia / Samplitude, and others. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「POW-R」の詳細全文を読む スポンサード リンク
