It would be interesting to make in the future version a configuration of sound cards separate part for broadcast on the Internet (for example integrate Edсast) that were 4 outputs:
1-normal, 2-FM ,3-Low delay ,4-stream. And that the stream could work simultaneously with other outputs.
And after make Preemphasis separately for each output.
FM-50/75, Normal-35/50, Stream-25/35ms ??

but then there is a problem with sample rate,because the Internet can have no more 44100,then it is necessary that in each of the outputs was an option of choice sample rate (I think it is hard to do)
Given that Internet radio is growing rapidly, this may it be interesting.

Hello Boris,

The intention of the "Normal" output was that that can be used for streaming...

Different pre-emphasis levels per output are difficult, because almost the entire processing is affected by it - so basically I would have to process everthing multiple times (which almost doubles the CPU load...)

Also, for best results, the input and all the outputs should use the same sound card - if you use different sound cards, the timing can be different (44.1 kHz isn't always exactly 44.1 kHz), which causes hiccups in the sound at the sound card that plays too slowly. I don't know if there are cards that support this many outputs???


I do know that it might be useful to reduce the de-emphasis that is performed on the normal output, to have more highs when streaming. That's already on my todo list.
