How to locate a character's pronounciation in the "animalese.wav"?

[2bdenny]

I want to extract only the pronounciation of "A", could you tell me how to locate it in this audio?

And I'm confused about this letter_library's 44 and Math.floor(i * pitch), I‘ll be grateful if you are willing to explain that =D!

data[c_index * output_samples_per_letter + i] = this.letter_library[44 + library_letter_start + Math.floor(i * pitch)];

hi extremely late reply but the animalese.wav is a 3.9 second audio that has letters A-Z pronounced in alphabetical order. each one is 0.15s (150ms) long, so the A sound is the first 0.15 seconds in the audio.

hope this helps!
