BS 6840-18 discusses sound system equipment with a focus on peak programme level meters. Guide for digital audio level. BS 6840-18 is the 18th part of the BS 6840 multi-series on sound system equipment that describes a digital audio peak level indicator for professional and consumer use to indicate the peak levels of sampled and quantized audio signals.
BS 6840-18 establishes a basic plan for standards development concerning the characteristics to be specified and the relevant methods of measurement for a digital audio peak level meter.
BS 6840-18 on sound system equipment is useful for:
Digital processing of audio signals is a common practice in the music industry, in audio equipment for consumer use, and in broadcasting. It is necessary to study a method to check, measure and indicate the peak level of digital signals because such a standard has not previously been developed since digital equipment came on the market.
BS 6840-18 offers specifications for the characteristics and performance of a peak digital coding level indicator, intended to measure the peak level of a digital signal at any desired point of a digital audio signal system. It is necessary to monitor overload in digital sections after A/D conversion as well as overload in analogue sections in such digital equipment.
