I often end up having to record the audio more than once for some segments because of poor quality or background noise during initial recording. I use the same microphone but may be in a different room or on a different laptop. This is more of a hobby recording so I don't have a professional studio. However, I want my audio to match and more often than not it doesn't. In fact, I often can't get it to match even when recording from the same exact laptop + mic setup, just because the microphone position happens to be slightly off. This is especially noticeable if I only record a single sentence to overlay rather than an entire segment.
What are my options for remedying this with budget tools such as Audacity and Davinci Resolve? I tried playing with the equalizer and frequency response but didn't achieve desired results, granted I'm still a noob when it comes to the equalizer. Thanks in advance.
