Re: The Waveulator: Two VCA-based Clipper Saturators

Glad to see this back. I would be interested in a stereo version for mixing, likely something I’d consider for live broadcast use in the field. I’ve given in to the idea most digital console limiters sound bad as peak-stop devices, and instead go with a slow attack/release safety that will still occ...

Re: New: A Direct-Coupled Input-Capacitorless Active Mic Preamp

Adding additional resistance to represent source impedance shifts both curves upward but large differences remain with typical 150Ω source impedances. Do those shifted differences track with this plot, or is the effect increased? This looks like 12dB difference at 50Hz, 6dB at 100Hz. In the zone wh...

The attack release changes are interesting. Looks like changing the RMS cap, and trimming the input resistor are both necessary if substituting in an existing build.

Re: Analog "POTS" Phone Service - US Copper Shutdown Imminent

I don't know about ISDN, I would imagine they aren't taking orders. I haven't had a copper line in a dozen years or more.
