Draft AES-5id-xxxx: Draft - AES information document for Room acoustics and sound reinforcement system modeling - Loudspeaker modeling and measurements - Frequency and angular resolution for measuring, presenting and predicting loudspeaker polar data

The document provides guidelines for measuring, presenting and predicting polar data from a single acoustic source or from an array of acoustic sources. It describes the relationship between resolution, in both the frequency and angular domains, and accuracy.
