Re: Spectrum analysis
The spectrum may be viewed by switching the track to the "Spectrogram" or "Spectrogram (log f)" view: http://manual.audacityteam.org/o/man/tr ... tml#spgram
Horizontal lines indicate the presence of a tone or a narrow band of frequencies. If the band is high in the spectrum, that may be audible as a high pitched whistle sound. horizontal lines can be filtered out using the notch filter: http://manual.audacityteam.org/o/man/notch_filter.html
To filter out high frequencies, use the low pass filter: http://manual.audacityteam.org/o/man/lo ... ilter.html
To filter out low frequencies, use the high pass filter: http://manual.audacityteam.org/o/man/hi ... ilter.html
For more complex filtering, see the Equalization effect: http://manual.audacityteam.org/o/man/equalization.html
The next version of Audacity will include additional tools for spectral editing.
