I’m using `IBufferSender` to send samples to a control that displays the harmonic content. It works, but only updates when sound is being processed. How can keep sending samples to the control during silence? Thanks!

There is a threshold of -90 dB where it stops sending. This was hardcoded, but I just pushed an update so you can set a lower threshold
