Sigma DSP delay 90 and decay

I was pulled into several high-priority, time-critical projects at work over the past few weeks and unfortunately I had to de-prioritize my participation in the forum as a result. So, I apologize for making you wait so long for an answer. I am going to try to respond to everybody's questions within the next few days.

1. Fixed phase shift for all frequencies

This topic has come up many times on this forum. The simple answer is "no", the SigmaDSP cannot implement an arbitrary phase shift for all frequencies of a signal. You can see more information about this topic in the following posts:

However, you can implement a 180 degree phase shift by inserting a "Signal Invert" cell into your project.

2. Decaying the volume when the input is below a threshold

Yes, this is possible. This function is called a Noise Gate. I have an explanation of a noise gate, along with an example project, here:
