Psychoacoustically Optimized Wordlength reduction is a sonically transparent digital word length reduction algorithm, reducing 20, 24, and even 32-bits files to the CD standard 16-bit format. Pow-r is technically not noise shaping, although it performs a similar function, and aims to retaining a high degree of perceived dynamic efficiency with very low noise. The algorithm is scalable, meaning it is ready for all sample rates, even to 192kHz and beyond.
