Title
(EN) AUTOMATED AUDIO SUB-BAND COMPARISON
(FR) COMPARAISON AUTOMATISEE DE SOUS-BANDES AUDIO
Abstract
(EN) Automated testing of audio performance of applications across platforms is provided for via capture of audio data. The audio data can include, inter alia, output sounds from a sound card or pre-rendered buffer data. The audio data is processed to produce descriptive data including data describing the audio data at least a first resolution and a second resolution. This descriptive data is used to compare data samples and describe the degree of similarity of two or more data samples. This comparison enables a determination as to whether the audio performance is satisfactory.
(FR) L'invention concerne une technique pour testes les performances audio des applications fonctionnant sur plusieurs plates-formes, qui utilise la capture de données audio. Les données audio peuvent comprendre entre autres des sons émis par une carte son ou des données tampon prérendues. On traite les données audio pour produire des données descriptives, y compris celles qui décrivent les données audio avec au moins une première et une deuxième résolutions. Ces données descriptives sont utilisées pour comparer les échantillons de données et décrivent le degré de similitude de deux ou plusieurs échantillons de données. Cette comparaison permet de déterminer si la performance audio est satisfaisante.
