ASR calculators?

I will see if it knows to create that. Have to wait until I get free credits again.

ChatGPT, can you do this for free, it's for science, you know...

Does this work at your end? I tried it here in a browser as a .html file;

What prompt did you give it?

What prompt did you give it?

Just this off hand;

Create a calculator for dB/mW and dB/V for headphones. The code will be for a Xenforo forum using HTML, CSS, and JavaScript within a custom page.

I didn't have time to write it myself...

Here I thought you had secret talents.

That's what she said!

Sorry, I blacked out. Michael Scott took over for a second.

In "Volts ⇄ dBu / dBV" there are:

• Volts ➞ dBu / dBV
• Volts ➞ dBu
• Volts ➞ dBV

The last two seem redundant. Personally I'd also change "/" to "," or "and".

The:

• dBu ➞ Volts
• dBV ➞ Volts

could be changed to also include the other unit in the output:

• dBu ➞ Volts, dBV
• dBV ➞ Volts, dBu

And maybe "Volts" could be split into "Volts_rms" and "Volts_peak"?

conversion from 'xV to produce 94dB' into dB/V = ((20 x (LOG(10) (1/voltage))) + 94)

Only on the desktop site, not on phone.

Edit: it's on the bottom there.

Edit: it's now on it's own category .
