Next I tested the pitch shifting technique using digital tools, following on from my meeting with Craig Bratley who went through the way I could split one input through 4 speakers I tested the pitch layering using Adobe Audition. This is effective to allow for greater control over the changes in pitch, you can input a value yourself and this can be in point increments. I tested this using just an input from a laptop internal microphone and then four different pitch effects added to each track. I used the range from +1.5 to -2, it seems with the digital the higher pitches are more prominent which meant that at +2 this overpowered the lower pitches making them harder to notice. Capping this at +1.5 created a more stable overall effect, where you can pick out each of the pitch changes even when layered together. I feel the digital tool will work better for my project as it again brings in the synthetic and further communicates this synthetic translation of the natural voice.
