Off-topic, αλλά σχετικά με το Purifi για όποιον είναι περίεργος σαν και μένα:(Το πιο ενδιαφέρον στο linkedin του Bruno είναι το τελευταίο project, το Purifi που τρέχει από το Δεκέμβρη σε συνεργασία με Lars Risbo και Peter Lyngdorf - "We are still in stealth mode - stay tuned...". Room correction? )
Louder, Cheaper & Better Through System-Level Optimization of Speaker, Amplifier, Power Supply & Intelligent Signal Processing
Abstract:
Active speaker systems are commonly designed by choosing one component at a time (speaker, amplifier, power supply, DSP processing). Lots of design practices and standards have been built up over many years around this component-based approach. However, this leads in practice often to over- or under-design of the components of the system which impairs both performance and cost. For example, speakers are built heavy and rugged to meet standard power tests leading to poor sensitivity and linearity. The paper is looking at the un-tapped cost and performance potential in co-optimizing the entire chain by taking the system-level view. Now, speakers can be optimized for sensitivity and linearity while the intelligent processing protects it from damage and enhances the audio quality.
