WaveSurfer Spectrograph
Originally uploaded by raprice.
This is the spectrograph for the Eastern pewee displayed in WaveSurfer. The top part is the spectrograph, the bottom is the wavebar (which is the only thing that SoundStudio displays). You can see the time axis between them. I've trimmed off the Hz axis (ranging from 2 to 6.5 kHz) in this screen shot in order to capture the pee-oo sound at the end. The leading pee-o-wee phrase was repeated 6-7 times.
The spectrograph isn't all that clear because of the background hiss in the recording. This can probably be reduced after a bit of time with the manual. Same applies to getting the time for both the wavebar and spectrograph to line up. As it is, the time axis applies to the spectrograph only. The wavebar shows a larger timeframe and functions as a 'big picture' viewer.
