what’s the minimum for two tvs simultaneously streaming video with multi-track audio?
You have too much network bandwidth!!
As I was fiddling around with my Roon streamer, putting the finishing touches on the network configuration I started monitoring the network throughput of the end point. With a stereo 196 kHz/32 bit audio signal it uses about 1.5 Mbits/second of bandwidth.
This means a typical 1 GigE could support about 70 simultaneous high resolution audio streams. Even an old-school 100 Mbit network could handle 9 of them.
My point really is just that chances are good your home network already has much more bandwidth than you need for high resolution audio.

@cleeds That is objectively true, but on a typical modern CPU or streaming device, the time taken to decode a level 8 FLAC file (highest level) can be considered to be negligible and often falls within milliseconds. I think the next step is to use a GPU integrated with a CPU to do decoding once the price of them comes down significantly. That would eliminate the latency from the CPU to pass data to the GPU. Apple is already doing something similar with the M-chip line which makes them ideal CPUs for AI. |
@daveteauk Buddy, you are seriously going to try to police my posts? Maybe if you don’t like what gets posted on this site YOU should go and listen to music instead? Or maybe read how others, who do care about this thread, engage, and if it’s not for you, move on? How many threads do you reply wiht "this isn't for me, why don't you not post this?" a day?

HQ Player Client shows Qobuz streaming bitrates in real time. I was similarly surprised to find low (<5 Mbps) bandwidth rates for streaming HiRes audio. When I see frequent agonizing over pricey audiophile switches and CAT6 hardware, it begs the question why if one has a WiFi signal that delivers high bandwidth with low latency and high reliability, why consider a galvanic connection (e.g. ethernet) and the extraneous noise it introduces? @tomrk Incidentally, HQ Player integrates the GPU with the CPU for sharing the load of upsampling/shaping/filtering algorithms, but only later NVIDIA processors support this feature. Orb (orb.net) is a free app for just about any platform that allows one to asses and monitor latency, packet loss, and overall system speed and quality in real time.
