Audio quality bottlenecks shifted from storage to transducers
Evidence
Historically, the bottleneck in audio quality has been the storing and transmission systems, such as gramophones, vinyl players, and cassette decks. The concept of high fidelity was developed to measure and minimize different deviations from perfect responses, such as linear and non-linear distortions. Nowadays, digital transmission has practically removed such problems, and currently the biggest bottlenecks are the microphones and loudspeakers. However, new challenges have emerged with perceptually based lossy audio codecs. — Ville Pulkki, Matti Karjalainen, Communication Acoustics- An…, 2360
