Re: Programmatically binding an audio file with its text equivalent

I agree on both counts. It does seem kinda basic, but I’m sure there’s a valid reason. The whole purpose of these articles is to provide simple and reliable accessibility tips, and I’m voluntarily following a strict format which limits how much info I can share. So involving any kind of scripting goes beyond what I’m interested in providing for these. Which is also why I relied to a simple link following the audio file, as unsatisfying as that may be.
