I can honestly say I have never done that process, ever,,,, not once in my life. I started on 4-track reel to reel 1/2 inch tape (Teac 3340s) and then had experience on 24track 2 inch and wide mixing consoles... before jumping into digital audio (eMagic Logic with Pro Tools cards in a Powermac). Very rarely a band/artist and I decide to use tape... (Regina Spektor's Soviet Kitsch was an example, and more recently New Silver Girl (from Helsinki, Finland) recorded on tape at the legendary Hansa Studio with me in Berlin). Some times I'm sent vocals to mix that were recorded (in my view) very blandly, or too clean... and then I use UAD ATR tape emulation, along with UAD LA-2A emulation, or Distressor emulation and very often Soundtoys Decapitator to rough up the vocals and give them some of the excitement that could have been included into the original recording session!
If I want to destroy voice sounds for fun and profit: I like Amp Farm, SansAmp (plugin) those work cool.
