| Pieplow's books on bird song are fantastic. Each page has a
| tiiiiny picture of the bird up in the corner, then a big spread
| of spectrograms and a decent chunk of text to give the
| spectrograms context: eg, what are the 'typical' parts of it, vs
| what varies, how likely it is that subsequent vocalizations are
| the same/different, what to expect in variations by sex and age,
| and so on.
|
| But my favorite part of the book is the introduction. In addition
| to just a great intro to reading spectrograms and what's up with
| bird vocalization physically (they have a syrinx, not a larynx),
| there's a lengthy section with a kind of 'phonetics' of bird
| song. It's great.

| process.
|
| I suspect doing it a lot leads to some purposeful synthesia where

| spectrograph.
|
| Here's the first example I could find:

|
| Armed with that knowledge I started looking at more
| spectrograms of birds (I record birds around my house and pass
| through bird.net's model. Amusingly, I kind of learned
| eveyrthing in this article just by looking at lots of
| spectrograms- they are far, far easier for me to parse than any
| other musical representation.
|
| I just found 'demucs' and am really enjoying doing source
| separation and then looking at the resulting spectrograms, then
| back at the original full musical spectrogram- it helps me
| parse out the instruments a lot better when they overlap.
|
| There is also a product called 'Celemony DNA' which can do some
| editing in spectrogram space to remove individual notes.

|
| Try a rolled "r", vowels, consonants, "p", "f" ("eeeffff")
| etc.
|
| Also try whistling if you can.

| Online spectrogram options:

| Sort of works on mobile, go to landscape and tap the mic

| Doesn't work on mobile anymore? But should be good desktop

| The audio is a landscape, and anything that isn't a "global"
