A skeptical, evidence-driven tour of the audio codecs that actually matter: MP3, AAC, and Opus on the lossy side; FLAC and ALAC on the lossless side; the MQA fiasco; and the psychoacoustics that make any of it work. We take ABX blind testing seriously, name real transparency thresholds, and debunk the audiophile myths that fail under controlled listening — while being fair about where the differences are real.

It is about A2DP codec negotiation, the SBC fallback and its bitpool ceiling, AAC's inconsistency across phones, the aptX and LDAC marketing math, the latency-versus-quality trade-off, and the slow split to LE Audio with LC3 and Auracast. This is the protocol-level honest version.
