I pretty much have a good handle on how to clean up video footage... if I am given an old VHS tape of a music video... the video portion is fixable...
but I know next to nothing about audio cleaning? given a wav file... how hard is it to clean...
yea... that's vague... but examples of audio damage would be
Compression (someone used mp3 source... i need to re compress it to AC-3 or Layer-II... is there a pre filter to clean up the audio slightly... like doing a msmooth on video before compressing it?)
over driven (someone doubled the audio volume when recornding to tape)
under driven... the audio uses 20% of the avaible range... (can it be increased to 95%... with out a sinple volume adjustment... to help with quality?)
reduced quality... (someone stored the audio as 22 khrz and/or 8 bit)
I am ultimatly looking for a nice setup of standardized steps that I can take older audio and store it in a 192-320 kbps AC-3 file
