Standard MP3s (320kbps) and even standard CD streams cut off frequencies above 20kHz and add compression artifacts. The 88 kHz FLAC preserves ultrasonic frequencies. While you can’t "hear" above 20kHz, those frequencies interact with audible sound waves, creating "air" and "space" around the cymbals.
This specific file format represents a significant jump in audio quality from standard CDs (44.1kHz / 16-bit). Aerosmith - Toys In The Attic -1975- -FLAC- 88
First, let’s demystify the number. When you see "88" in digital audio, it almost always refers to (88,200 samples per second). This is not an arbitrary number; it is a mathematical twin of the standard CD sampling rate, 44.1 kHz. Standard MP3s (320kbps) and even standard CD streams
