3. You need a simple, reliable, home-recording setup. Keep in mind: Your objective is on being the best voice talent you can be, not the best production studio or recording engineer. Nevertheless, you do need the ability to record, edit, and turnaround a proper audition. Do not run out and purchase a mic! You can’t return it, for hygienic reasons. Besides, there’s a bit of a learning curve to this and recent industry advances have made having a home “studio” easier and more affordable than ever before. You could have the best gear and the coolest toys on the block, but if you can’t use them it’s a waste. (Tip: What you’re recording on matters less than where you’re recording. Find a quiet place like a closet full of clothes to record in.)
As the engineer, your key job is to select and set up the recording space, choose and position the microphone, set levels and make sure you're recording a good, clean signal at a healthy level. Like music, the louder the signal you want to record, the less audible the noise floor, but you don't want to have to speak louder than sounds natural, and you don't want to overcook things when tracking: any distortion will be very noticeable on an exposed voice part, and an otherwise great take with digital clipping won't be acceptable. If you notice clipping only when you start editing, software clip restoration tools might help to make the take usable, but it's not going to be perfect. Remember that although you may have needed to record 'hot' on analogue tape and older 16‑bit digital recording systems, modern 24‑bit A‑D converters can accommodate a much wider dynamic range, so you no longer have to track so loud: you can leave much more headroom.
