Choose below the option that's NOT correct regarding audio compression and information loss?
Lossless audio compression produces a representation of digital data that decompress to an exact digital duplicate of the original audio stream, unlike playback from lossy compression techniques such as Vorbis and MP3.
Only in lossy compression (not in lossless), information redundancy is reduced. Methods such as coding, pattern recognition, and linear prediction are employed to reduce the amount of information required to represent the uncompressed data.
Lossy audio compression algorithms provide higher compression at the cost of fidelity and are used in numerous audio applications. These algorithms almost all rely on psychoacoustics to eliminate or reduce fidelity of less audible sounds, thereby reducing the space required to store or transmit them.

Audio data compression has the potential to reduce the transmission bandwidth and storage requirements of audio data. Audio compression algorithms are implemented in software as audio codecs.
