the ideal world, every time you use a recording device the results
would be pristine audio. All speech would be clearly intelligible and
your recordings would be immediately usable for their intended purpose.

such as background or street sounds, low recording levels,
interference, buzz, hum and hiss. Enhancing problem audio can reveal
critical clues, possibly saving additional man-hours and expense, while
making the case.
