I have a recording with two people speaking. One of them has a much louder voice that the other and I am looking for a way to raise the volume of the other guy. Can you help me?
The real solution is to re-record with your microphone(s) positioned and set to record both speakers at a good (not too high, not too low) level. Preferably this would be done with two microphones (one each), with one panned all the way to the left, and the other panned all the way to the right. That would allow you to split the stereo track into two mono tracks, so that you can then process each voice separately.
Attempting to fix this problem after the event (assuming that both voices are on the same track), is a salvage operation. How good or bad the results are, largely depends on how bad the problem is. There is an optional “Nyquist plug-in” called “Level Speech” https://wiki.audacityteam.org/wiki/Nyquist_Effect_Plug-ins#Level_Speech
Instructions for installing Nyquist plug-ins are here: https://manual.audacityteam.org/man/installing_effect_generator_and_analyzer_plug_ins_on_mac_os_x.html#nyquist_install
Tip: Mac has a nasty habit of adding “.txt” to the end of the file name of Nyquist plug-ins. The name of this file must be “LevelSpeech.ny” and not “LevelSpeech.ny.txt”. Check that the file name is correct, otherwise it will be impossible to install.
Thank you! Now I have dowloaded the plugin, and put it in the right place, but I cant still see it when I try to “manage plugins”…
