You'd be better to fix the 'phone recording - how are you making the
recording and are you recording it to a computer, or using a phone to tape
recorder? If it's a landline phone, buy a telephone to PC adaptor, or if
it's an internet call like Skype, get free recording software like Voice
Emotion meant for recording those type of calls.
If you normalised a part where only he was speaking and you just brought up
the background noise too much, the recording of his voice may be too bad to
do anything with it, but maybe you should have :
* tried a less aggressive noise removal first
* then compression without normalising (or levelling instead - might create
* then some sort of EQ (maybe boost 1 Khz - 4 KHz which are the frequencies
the ear hears most loudly)
* then normalize
Without hearing the MP3, it's hard to say any more. As long as you are not
expecting miracles and don't expect it done immediately, post it on the web
somewhere, or upload it here to Nabble if it's not above their size limits,
and maybe I will have a listen to it.
