Standard streaming formats and MP3s rely on lossy compression. This process shaves off frequencies at the extreme highs and lows to reduce file size. For standard synth-pop, this might pass unnoticed. For Safri Duo, it is devastating.
A "transient" is the initial high-energy burst of sound when a stick strikes a drum head or a hand hits a conga. In lossy files, these fast attacks are smeared, resulting in a dull, muddy thud. In FLAC, the crisp snap of every bongo hit is perfectly preserved, giving the music its signature punch and urgency. 2. Expanded Soundstage and Separation Safri Duo Greatest Hits 2010 FLAC
