For curiosity's sake, let's have a scenario: "Wow, I really like Shadow Fiend's voice lines. The effect is awesome! But I have no idea how to recreate it! I have Adobe Audition but I just don't know how!"

Well, friend, I did the hard work for you-- it isn't exact due to the variance of the human voice, but I'll explain:

The issue with recreating Shadow Fiend's voice is: Gasp! The terrifying Multitrack mix.

And not only that-- you'll need to edit about 5 different voice files-- but have no fear, it's not as intimidating as you think!

Step 1: Record Line.

Step 2: Insert it 6 times into Multitrack Mixdown.

Step 3: Add the Graphic Equalizer (10 Bands) effect into Track 1, Track 2, and Track 3. With this parameter:

<31: 20.

63: 17.

125: 5.5.

After this, you'll have to modify the second and third, but we'll keep Track 1 like this to make it the "Deep" one.

Still with me? You've got this, I know you do.

Step 4: Add the Pitch Shifter effect. Track 1 should have Semi-tones set at -4(or deeper, depending on your voice) and can vary in Cents. I put mine to 95 due to my own voice.

Step 5: Repeat Track 2, but set the Semi-tones to 4. This will be your "squeaky" or "high" voice.

Step 6: Add the Full Reverb effect to Track 1 and Track 2. Feel free to modify to suit your needs:

Decay Time: 92 ms.

Pre-Delay Time: 3.4 ms.

Diffusion: 670 ms.

Perception: 29.

Room Size: 20.

Dmension: 0.66.

High Pass Cutoff: 45 Hz.

Dry: 42.3%.

Reverberation: 2%.

Early Reflections: 1%.

Repeat for Track 2.

Step 7: Set Track 1 to +2 decibels/+2 on the volume dial(left dial above the white line/right under where it says "Track 1"). Set Track 1 to -13.5.

Right, so we've got those two down...

Now for the next three.

Step 8: Add the Surround Reverb effect to Track 3. Set the Impulse to "Octagonal Room" with these parameters:

Room Site: 100%.

Damping LF/Damping HF: 70%.

Pre-Delay: 100 ms.

Front Width/Surround Width: 100%.

C Wet Level: 97%.

Mix: 100%.

Gain: 7.5%.

Step 9: Add the Echo effect to Track 3 with these parameters:

Delay Time: 990 ms(or less, depending.)

Feedback: 9.5%.

Echo Level: 75%.

Successive Echo Equalization:

86 to 1.4K: -15.

3k: -4.45.

7.4k: -5.10

22k: -4.

Step 10: Set volume of Track 3 to -8.5, or until it is less audible than the other two.

Nicely done. Now the next two are simple:

Step 11: Copy + Paste Track 1 and Track 2. Make Track 4 and Track 5 with these.

Step 12: Add the Echo effect to Track 4 and 5 with these parameters:

Delay Time: 990 ms(220 onto the higher pitched track. Make it less if needed for either.)

Feedback: 11.80%.

Echo Level: 75%.

Successive Echo Equalization is the same as Track 3.

Step 13: Set volume to -11 for both tracks.

That should be it! Modify as you see fit. Make sure to go to File > Export > Multitrack Mixdown > Entire Session to save!
