TMBWOD Audio Production

A full day working on the production for The Many Beautiful Worlds of Death audiobook. This is the fun part, made so much easier by Prometheus! After maximising the basic recordings I apply basic dynamics, then load those waves into Prometheus to apply effects, always a high pass filter (plan voice recordings are always too bass heavy), a noise gate, and a tiny bit of reverb.

After that, special effects for the work in hand. I've applied a tinny voice filter to Arturo, the funny robot man, a reedy voice to the gramophone, a telephone effect for God, and a thinner voice for Adam, the mechanical child. For the main computer of the trans-dimensional gateway, I used the very retro sounding AnalogX speech synthesizer. I experimented with the DEC Talk synthesizer (as used by Stephen Hawking!) but that sounded too realistic!

One tricky voice was for 2me, the emotional spirit entity. I read it plain but thought that a female squeaky voice might work. Turning up the pitch sounded good enough, but not intelligible enough, so I decided to tag on a sine wave which tracked the amplitude. This seemed to work well, fitting the description of a 'smooth glass' voice.

The main song was included, and I made a small edit of music, a few notes, for the introduction.

Then it was a matter of rendering out the final files and making tiny volume adjustments so make all waves between -20 and -21dB.

All is set for proofing now. I may re-record parts if I'm particularly unhappy with elements, though this would be troublesome at the moment. The entire book is a little over 5 hours.
