You may want to determine whether your app performs peak normalization or RMS normalization (or gives you an option of selecting which you want to use). I'm guessing your app already performs normalization and you don't need a plugin for it. MIQ responded to my search for a good, free parametric EQ here: I'm not familiar with any free noise reduction plugins, as I've never really had a need for them. Not sure if this will work for you, if your app even has the feature, or if you have a portion of audio that is only noise. Are you recording particularly quiet sources that make it difficult to achieve good levels? Maybe you need a preamp?Īs for noise reduction, some WAV editors support capturing a noise profile and then removing the noise profile from other sections of the recording. The best way to address the noise floor issue is to minimize it up front by running levels high enough that you're approaching, but not hitting, 0 DBFS (i.e. I think you'll find some of these functions already exist in the software you use, others are available as free plugins, and the more sophisticated require retail purchase.Īnd then there are those who take a purist approach to the recording - it is what it is, and they don't want to mess with it. I'm not really sure the intent of your question, so these are just some general functions often used for this type of thing.
