I am very new to Sound Forge, and audio editing in general, so please bear with me.

I am trying to standardize the sound of many speech samples. The volume and tonal quality
varies from sample to sample. Some speakers sound sharp while others sound flat. I was
able to standardize the volume, but not the tonal quality. What factors affect the quality, and
what does Sound Forge have that can be used to standardize the quality? I realize they can't all
be the same, but I need to establish a mid-range for all sound samples.

Also a consideration, I have a lot of files to work with, so I want to process a batch of files at
once.

Sorry I can't be more specific with my questions. Please respond if you can give me any tips at
all! Thanks!

I suggest you weaken the quality same amount from all the files.
compress a bit
1. normalize all -1
2. compress 2/1
3. EQ them all roughly
4. Normalize 10 RMS

will not sound nice, but all will sound same bad.
