Song Sleuth is suggesting species that sound completely different from what I recorded. What's wrong?
Check to make sure that you haven't zoomed in on a narrow frequency band, as the app will only analyze the visible frequencies on the screen (see filtering recordings)
The app is a computer program, and is using a strictly analytical approach to sound pattern matching. This means that it can return results that seem nonsensical from our perspective. Usually this is because there is some extraneous noise in the recording, and the app will sometimes suggest either very low-pitched sounds (e.g. Mourning Dove, Human, etc) or very high-pitched sounds (e.g. Cedar Waxwing, Black-capped Chickadee, etc) when we clearly hear something else.
In these cases simply filtering out the high and low frequencies and running the analysis again on the target sound should lead to a positive result. See the tutorial on filtering recordings.
In other recordings there might be confusing sounds before or after the target sound. In these cases it is helpful to trim, or crop, the unnecessary parts of the recording. This takes a little more effort than filtering, but leads to similar improvements in accuracy. Read more about trimming here.
