Well, the cycle is complete: Lesson Six on Polyphony is up. I’d love feedback from experts in audiospectrographic analysis in particular, because I may have messed up on some of the details this time around.
Of course, no sooner do I finish my lesson than I think of all the ways in which I could improve and expand it. I may work on that down the road. Meanwhile, the six-part series on this site will teach you basically everything you need to know about reading avian audio spectrograms. Enjoy!
I’ve finally posted Lesson Five on Nasality. It’s a bit of a doozy, but I’m proud of it, especially since it’s getting into some territory that nobody’s really published on before, at least vis-a-vis psychoacoustics, since Peter Marler’s classic 1969 article “Tonal Quality of Bird Sounds“.
For that reason, and because I’m afraid I may have made it a little overly complex, I’m particularly interested in getting feedback on this page. Let me know how it treats you. One more installment is planned after this one, on polyphony…and then we’ll have covered it all!
I’ve published Lesson Four on trills and beats. Lessons five and six may be a while in coming, since they are slated to deal with nasality and polyphony, which is where things start to get complicated. Stay tuned!
Lesson three is up; it covers noise.
Also, I neglected to mention it before, but I’ve been working on updating the Bird Sound Glossary as well. As I expand the spectrogram pages, I’ll add more “example” links to the glossary, and I’ll expand the number of terms as we go.
As always, comments appreciated!
I’ve just posted the first part of my online tutorial on how to read spectrograms. Lesson One deals with Pitch and Inflection. More lessons to follow; all will be permanently available through the menu bar.
Let me know what you think!
