Someone shot a wedding video and for about 50% of the shoot the sound was fine then the other 50% the sound was very, very low. What steps can I talk to raise the sound level of the remaing video so that it can be ok. I just need to do it on the second half of the audio track. Thanks for your help in advance.
If you don't have a noise reduction plug-in, you *might* be able to get away with using a noise gate after normalizing - this will replace all audio below a specified amplitude level with silence. This might be OK, depending on your circumstances, and what other audio tracks you happen to have playing to fill your newly-created gaps.
