fas's Issues

Audio computation should be float by default

Double was the default initially but it was changed back to float, "double" is still used in the audio callback for computations... all should be of float type.

Core synthesis engine: Implement SSE

GCC is already producing SSE instructions but only scalar operations, the code of the synthesis engine can be greatly optimized by using hand-coded SSE instructions, the only thing required to implement it is padded notes data so that we can take chunks of vectorized notes data and divide greatly the amount of instructions to compute the additive bits.

Allow SSL

Allow SSL to fix Firefox mixed content issues when a connection originate from a SSL enabled pages.

Should be activated by default and have a command-line flag to enable/disable it.

liblfds version ?

Hello,

In the doc, it is said that we have to clone liblfds711, but it seems that liblfds720 is needed.
Unhopefully, liblfds's last version seems to be 711. And the error log discourages me simply trying to rename the thing

Faust version

Which particular faust version does this require?

Can't seem to start server

Not sure what the issue is. I am on Pop!OS 20.10 (similar to ubuntu 20.10)

I have my portaudio routed through Jack, and generally either sort of audio works fine, in other apps. I tried with both runtimes and it quits.

Here is jack:
