BS EN 61606-1-2009音频和视听设备.数字音频部分.音频特性的基本测量方法.总则

This part of IEC 61606 is applicable to the basic methods of measurement of the audio characteristics of the digital audio part of audio and audiovisual equipment for all of consumer use, professional use and personal computer.The common measuring conditions and methods, described in this standard, are used for themeasurement of the performance characteristics of equipment having an audio bandwidth equal to approximately one-half of the sampling frequency of a system, where the audio information is processed in the form of digital data. CD players, DAT recorders, digital amplifiers, digital sound broadcast receivers and television broadcast receivers with digital sound are examples.This standard describes test methods for equipment which has digital input with analogue output and analogue input with digital output. Future revisions of this standard will cover digital-in/digital-out and analogue-in/analogue-out tests.This standard does not apply to a lossy compression signal and also does not apply to power amplifiers.NOTE 1 A digital audio system having an analogue input and an analogue output with digital signal processing may have different characteristics from those of a pure analogue audio system due to sampling of the audio signal and performance of incorporated A/D and D/A converters. Measurement methods described in IEC 60268-3 may not give correct results when applied to a digital system.NOTE 2 The methods described are mostly based on sampling frequencies of 32 kHz and higher.NOTE 3 For tests of those systems of digital-in – digital-out, and analogue-in – analogue-out tests, refer to AES17.NOTE 4 This standard is planned to harmonize with the first edition of IEC 61606 (1997)1, AES17 and EIAJ CP-2i50.

BS EN 61606-3-2008音频和视听设备.数字音频部分.音频特性的基本测量方法.使用

This part of IEC 61606 is applicable to the basic measurement methods of audio equipmentfor professional use.The definitions, measuring conditions and methods common to both consumer andprofessional equipment are described in the IEC 61606-1.This standard contains details of definitions and measuring conditions and methods applicableto professional equipment which differ from those described in IEC 61606-1.This standard excludes consideration of− measurement of low-quality audio devices,− measurement of low-bit-rate audio devices (‘sub-band’ or ‘perceptual’ coding devices),− measurement of devices which significantly modify time or frequency characteristics of thesignal, such as pitch shifters or reverberators,− measurement of signals from analogue input to analogue output, beyond the most general,− EMC and safety related testing.

BS EN 61606-4-2006音频和视听设备.数字音频部件.音频特征的基本测量方法.第4部分:个人电脑

This part of IEC 61606 specifies the basic measurement methods of a linear PCM signal for an audio part of personal computers (PCs) and applies to both desktop and portable computers. The common measuring conditions and methods are described in IEC 61606-1.Specific conditions and methods of measurement for PCs are given in this standard.NOTE 1 The methods described are mostly based on sampling frequencies from 8 kHz to 192 kHz and bit lengthfrom 8 bit to 24 bit.NOTE 2 This standard describes tests for equipment which has digital input with analogue output and analogue input with digital output. Digital input data are provided from an internal HDD or other memory media and outputdigital data are recorded to an internal HDD or main memories.NOTE 3 The methods specified in this standard are not applicable to systems incorporating bit-rate reduced digital audio signals that have data loss or to 1-bit signals. This part does not apply to analogue input with analogue output and digital input with digital output as described in IEC 61606-1.NOTE 4 When a CPU in a PC is overloaded by tasks other than those for audio input/output, the PC may fail to record/reproduce the whole audio data. This standard applies only to the measurement in which input/output data are recorded/reproduced without such missing data. The performance of a PC with missing audio data may be evaluated by the short-term distortion measurement although such evaluation is not within the scope of this standard.
