What is an SPDIF output?

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.

Is SPDIF input or output?

S/PDIF (Sony/Philips Digital Interface) is a type of digital audio interface used in consumer audio equipment to output audio over relatively short distances. The signal is transmitted over either a coaxial cable with RCA connectors or a fiber optic cable with TOSLINK connectors.

How do I add SPDIF to my computer?

To get SPDIF input your PC you would need to add a sound card to your PC. You need a sound card like ASUS XONAR DG Headphone Amp & PCI 5.1 Audio Card. Using this card the PC supports digital audio output for: TV and music: two-channel stereo.

Which is better HDMI or Spdif?

And we finally arrive at the cream of the crop – the HDMI cable. Even though you probably associate it with high-resolution video more than audio, it’s also your best bet for sound. It supports the latest lossless Dolby sound formats like Dolby TrueHD and DTS HD Master Audio that are widely used on Blu-Rays.

Is Spdif better than aux?

Even though there is not much difference in the audio quality, it is supported by most modern home theaters. When you use optical input with a surround sound system, the result is better than AUX input.

Is USB better than SPDIF?

As we see there is zero difference between the two interfaces as expected from a properly engineered DAC. The same theme continues: USB performs just as well as S/PDIF even in this older DAC. S/PDIF output is full of jitter components so audibly worse than USB.

Is USB better than optical?

Optical cables are intended to just directly pass the digital data from one location to another using light. Can’t get much faster than light, so… No, USB is not “faster” than Optical. And distance is also not an issue, but in most Home Theater environments, not really an issue for USB either.

Is SPDIF same as RCA?

While they look similar because of the RCA connector (Phono Plug),it is not the same. SPDIF cables have a stereo digital connection, whereas RCA cables have a mono analog connection. There are no SPDIF to RCA cables, so you would need an RCA to S/PDIF converter to achieve that.
