What are SPDIF inputs?

S/PDIF (Sony/Philips Digital Interface) is an audio transfer format interface. It transfers digital audio signals from one device to another without the need to first convert to an analog signal, which can degrade audio quality.

What are SPDIF ports used for?

A common use for the S/PDIF interface is to carry compressed digital audio for surround sound as defined by the standard IEC 61937. This mode is used to connect the output of a DVD player or computer, via optical or coax, to a home theatre amplifying receiver that supports Dolby Digital or DTS.

What is SPDIF used for in recording?

An S/PDIF connection allows for the possibility to transfer two audio channels (stereo sound) in uncompressed digital form (PCM). What’s more, in compressed form, it’s even possible to get digital surround sound (5.1/7.1 DTS) when plugged into certain devices.


The Basic Comparisons: Both HDMI and S/PDIF with optical cables pass digital audio from one device to the next or from source media to sound display like stereo speakers or a soundbar as well as an AV receiver. Both optical cables for SPDIF and HDMI cables for HDMI ports are relatively cheap as well.
