Application Note: Loudspeaker Rub and Buzz Measurements Although developed independently from Audio Precision, this algorithm has much in common with the one used to derive the Peak Ratio in the original APx rub and buzz result
Performance Metrics | FluidInference FluidAudio | DeepWiki This document defines the performance metrics used throughout FluidAudio to measure accuracy, speed, and efficiency Metrics are calculated during benchmarking and can be tracked programmatically via
AN012 - Peak, RMS and averaging circuits For most measurement systems, this will be done using one of the full wave precision rectifier circuits described in AN-001 This part of the process is critical, and the type of circuit used is determined by the required accuracy, signal frequency and the level
Application Note: Loudspeaker Rub and Buzz Measurements | Audio . . . Amongst the many tests quality assurance puts a product through, in an acoustic product like a loudspeaker, detecting Rub Buzz is critical before the product is shipped to the end customer In this application note, we introduce what Rub Buzz is and define four Rub Buzz detection results used on production lines
Raising the Bar for Rub Buzz Defect Detection - AP Rub Buzz Loudness (new with v6 1) – Applies a psycho-acoustic loudness model to the residual signal to calculate the perceived level of the rub and buzz based on well-established models of the human perception of sound
Speakers: The Evolution of Production Line Rub Buzz Measurements Rub Buzz defects are almost exclusively introduced in the manufacturing process The term “Rub Buzz” refers to the presence of higher-order harmonics, which create a harsh buzzing sound that often becomes particularly obvious at higher playback levels
