HANDLING NOISE -CHIRPS ETC.
When you are out in the field there are always a chance you bring home sounds you never planned for, these could be yourself touching the microphone, cables, twigs touching the parabola etc. In audacity there are ways to get rid of such spiky noise, as long as the noise is not a part of the song/call. I share here some of my experience how to do it.
First step when you have identified the unwanted noise is to find and mark a nearby area with similar noiselevel as your noisy bit.
Then mark a portion of the recording and copy it ; Ctrl + C
Next step is to mark the noisy bit the same width (= amount of time) not to destroy the intervalls in the song sequency.
Then Paste; Ctrl + V
The vertical line is now gone and you can go further in editing the recording.
I choose to reduce some of the bottom noise, and uses High Pass filter; 6dB 1500 hz to reduce the general noise, then to reduce the coarse lowest part I chooses High Pass filter and 12dB 300Hz. In this case it should produce a nice noisefree file.
