Hey, that's a neat challenge! Here's what I did to create the tone I've attached:

1. Generate->Silence->1 second
2. Ctrl+'a' to select all.
3. Alt+'c' (Effect menu)-> Nyquist prompt
4. Typed: (osc-tri 440), tabbed to OK and pressed enter.
5. Right arrowed about 1/4 of a second, pressed shift+'j' to select.
6. Alt+'c', pressed 'f' to jump to Fade In and pressed Enter.
7. Left arrowed about 1/4 of a second, pressed shift+'k' to select.
8. Alt+'c', pressed 'f' to jump to Fade Out and pressed Enter.

It's kind of fun to Change Speed on the file to get the different notes. It makes it sound a lot more like the plinky sound in the file you attached. Change Speed is also under the Effect (alt+'c') menu.

I know it's not exactly like the sound in your file, but maybe it helps get started creating your own?

Best,
David

I wonder, how would I make triangle tones that sound like piano notes? As
heard in this example.

No the built-in generator does not do triangle tones, but you can
generate triangle tones using the Nyquist Prompt effect.

If you select part of a track, open the Nyquist Prompt effect, and
enter the following command (note that the parentheses are essential),
it will generate a 0 dB (full scale) triangle tone in the selection at
440 Hz. Here is the code:
(osc-tri 440)

For a different frequency, just change the 440 to whatever frequency
you require.
To create a tone at lower amplitude, you can either, apply the Amplify
effect to the generated tone, with a negative amplification amount, or
you can extend the code a little. For example, to create a 1000 Hz
triangle tone with an amplitude of -6 dB (which is half of the full
scale amplitude) - the code is:

(mult 0.5 (osc-tri 1000))

Hi, it's Annabelle.
I know the tone generator within Audacity can generate sine, square,
sawtooth, and square no alias tones, but I wonder if it's possible that this
generator can generate triangle tones.
