So in some of the wiki helps, I saw some advice for mics and Audacity, which was largely, Turn them both up. I have a Blue Yeti, which of course, has its own gain control. I keep it at about halfway for other applications I am using, but in Audacity, if I turn the mic level all the way up (and worse yet my fair Yeti), the sound is through the roof. I know that people read at different levels and what not, but for those of you Yeti/Audacity users, do you have a general 'magic' spot for them?
Audacity is free software for Mac and PC that allows for the simple functions of recording audio and reducing noise. The Blue Yeti can really pick up quite a bit of background noise, so while recording monologues in a quiet place to start is a great idea, you will want to apply a noise reduction to double up.
Speaking louder into the microphone is the number one thing that will make your voices less quiet.
Being confident in your delivery and speaking as loud as your character would be in their current situation is what will help you project your voice and make it clear and distinct.
As well I know a useful trick that should do you wonders. It's an Effect called Noise Removal.
It will remove the background noise of recordings so you can increase the volume of your voice without making room noise super obvious.
I'll go through it step by step.
-Before you do a recording, hit the record button and let your microphone record for about five seconds without saying anything at all.
-After this period of time, do your recording as you usually would.
-Highlight the time where you didn't say anything.
-Go to Effects and select Noise Removal.
-A menu will pop up, from here click 'Get Noise Profile'
(Now Audacity recognizes the background noise that your mic is picking up)
-Select the track your recording is on.
-Go to effects and click on 'Repeat Noise Removal' (it should be at the top)
-Listen to your recording again, if you can still hear the background noise, click 'Repeat Noise Removal'.
Repeat as necessary.
(WARNING! If you said anything at all during the silence period, Audacity will remove certain frequencies of your voice from the recording, which will result in you glitchy and unusual)
Your recording should now be mostly clear of background noise, this will allow you to increase the amplitude of your recording without making the background noise super obvious.
Keep in mind that a good delivery is the best way to get good volume.
Hope I was helpful in some way! :P
