Γιατί 24bit 44khz
AI απάντηση :
“
Short answer: because it’s the best “lossless-at-scale” sweet spot.
Why 24-bit/44.1 kHz specifically?
Net-net: 24-bit addresses the meaningful fidelity gap (processing headroom and noise floor) while 44.1 kHz avoids unnecessary sample-rate bloat—giving Spotify a true lossless tier that’s audibly transparent for music, technically clean, and economically scalable. “

Why 24-bit/44.1 kHz specifically?
- Matches the native master for most music. 44.1 kHz is the historical distribution standard (CD lineage), so using it avoids extra sample-rate conversion on the vast majority of tracks. Less SRC = fewer opportunities for artifacts.
- Audible benefit where it counts, without overkill. Jumping from 16-bit to 24-bit meaningfully increases dynamic range/headroom (≈96 dB → ≈144 dB), which is useful for level-normalization, crossfade, and other DSP stages—even if final listening rooms can’t exploit the full range. Going from 44.1 to 48/96 kHz yields far smaller real-world gains for music playback.
- Bandwidth & cost efficiency. 24/44.1 FLAC is truly lossless but much lighter than 24/96 or 24/192, making it feasible to ship to hundreds of millions of users without a price hike—which Spotify explicitly says it isn’t doing.
- Fits Spotify’s existing pipeline and device ecosystem. Their official spec is “up to 24-bit/44.1 kHz FLAC,” which slots neatly into current ingestion/streaming workflows and plays nicely with most Connect devices.
- Minimizes avoidable resampling. Many phones/OS mixers run internally at 48 kHz; if Spotify delivered mixed sample rates widely, you’d get more on-device SRC anyway. Sticking to one well-supported rate helps control where conversion happens.
