Editing your audio is great, but just like editing photos, it should be done as minimally as possible and in such a way to make the media more similar to the experience you had in the field.
The risk with editing audio - or photos - is that you can distort the media such that it is not representative of what actually occurred in the field. For example, by boosting contrast and saturation and adjusting colors in a photo, you could make a Cassin’s Vireo look more like a Blue-headed Vireo.
This is part of why eBird recommendations suggest only trimming and amplifying audio. That way no information is being lost, or added.
More important than editing audio, is obtaining decent quality audio in the first place. What this means is reducing background noise as much as possible - don’t have people talking in the background for example, or wait until there is a lull in other bird noises to obtain audio of your target. Basically your results will be better if you try to do more quality control on the front end, rather than the back end.
