Nous décrivons une méthode de compensation des fluctuations de température par un traitement de déformation temporelle linéaire dans un système de reproduction sonore. Cette technique est appliquée aux réponses impulsionnelles des fonctions de transfert de salle, pour obtenir un système de reproduction sonore de haute qualité, notamment celui traitant les composantes hautes fréquences. Premièrement, les réponses impulsionnelles sont mesurées avant et après la fluctuation de température, et les premières sont converties en secondes par le processus proposé. Ensuite, nous concevons des filtres inverses pour le système et évaluons l’amélioration de la précision de reproduction et de la distorsion spectrale. Grâce à la méthode de compensation, nous pouvons améliorer la précision de la reproduction à n’importe quelle fréquence. De plus, nous proposons un algorithme adaptatif pour l'estimation d'un taux de déformation approprié, utilisant le signal observé du son reproduit obtenu à un seul point de contrôle. En utilisant l'algorithme proposé, nous pouvons améliorer la précision de reproduction à chaque point de contrôle d'environ 14 dB, dans lequel la différence de température est de 1.4.

Abstract: We describe a method of compensating temperature fluctuation by a linear-time-warping processing in a sound reproduction system. This technique is applied to impulse responses of room transfer functions, to achieve a high-quality sound reproduction system, particularly one that treats high-frequency components. First, the impulse responses are measured before and after temperature fluctuation, and the former are converted to the latter by the proposed process. Next, we design inverse filters for the system, and evaluate the improvement of the reproduction accuracy and spectrum distortion. By the compensation method, we can improve the reproduction accuracy at any frequency. Moreover, we propose an adaptive algorithm for the estimation of a suitable warping ratio, using the observed signal of reproduced sound obtained at only one control point. Using the proposed algorithm, we can improve the reproduction accuracy at each control point by about 14 dB, in which a difference in temperature is 1.4
