What is this BS EN 60958-4-1 - Professional applications for digital audio about ?
BS EN 60958-4-1 discusses digital audio interface with a focus on professional applications. BS EN 60958-4-1 is the fourth part of the BS EN 60958 multi-series on the digital audio interface that specifies the format for coding audio used for the audio content.
BS EN 60958-4-1 is expected that the audio data will have been sampled at any of the sampling frequencies recognized by AES5. The capability of the interface to indicate other sample rates does not imply that it is recommended that equipment support these rates. To eliminate doubt, equipment specifications should define supported sampling frequencies.
Who is BS EN 60958-4-1 - Professional applications for digital audio for ?
BS EN 60958-4-1 on professional applications for digital audio is useful for:
- Manufacturers of products that provide audio output (televisions, phones)
- Audio equipment manufactures
- Audio programmers
- Music producers
- Sound technicians
- Recording and dubbing studios
Why should you use BS EN 60958-4-1 - Professional applications for digital audio ?
The two-channel digital audio interface has been widely used in a variety of professional audio applications that have reached beyond the vision of the original standard. In particular, applications using increased sampling frequencies and alternative physical media. BS EN 60958-4-1 defines the format for coding audio used for the audio content. BS EN 60958-4-1 specifies the semantics of the audio data, including the "validity" flag. BS EN 60958-4-1 also specifies the sampling frequency by reference to AES5.
Together with IEC 60958-1, IEC 60958-4-2, and IEC 60958-4-4, BS EN 60958-4-1 specifies an interface for serial digital transmission of two channels of periodically sampled and linearly represented digital audio data from one transmitter to one receiver.
What’s changed since the last update?
BS EN 60958-4-1:2016 supersedes IEC 60958-4:2003, which is withdrawn. BS EN 60958-4-1:2016 includes some technical changes with respect to IEC 60958-4:2003.
These include:
- Support for a wider range of physical media
- Support for a wider range of audio sampling frequencies
- Deprecation of “minimum implementation” of channel status data
