BAD audio quality (voice over) is killing your business!
You could have Morgan Freeman narrating your advert but have him record in a dumpster with a bagel (for you Americans out there) as a microphone and you will have people turning off, left and right. That means your costly copy written advert that you spent $$$ on is down the toilet. Your message, product or service is not being seen or heard in the glowing light you want it to be.
