How a network switch affects audio playback – An extreme deep dive!

For the past few weeks / months, your author has locked himself in a measurement room with lots of switches and loud measuring equipment. This, in order to do some research on the influence of network switches on audio clocks. Will we succeed in finding “proof”?

How to create a great network for streaming audio?

Check out a sneak peek of this content! Alpha Audio has been heavily involved in streaming audio for (well over) a decade.

Audible differences Codecs – MP3 – AAC – Ogg – FLAC

After the story about audio codecs, we felt strongly about putting them to the test. What do they sound like? What are the differences? And how can we easily demonstrate that? And of course: let you hear it. We grab our reference track and get to work with Foobar and Adobe Audition!

From AAC, DSF and Flac to Mp3, Ogg Vorbis and WAV – Codecs
