This is a useful tool for finding blips and blerps to use for games.

Yes, really useful indeed.

I wrote this for convenience when using TinyGo:

type Sound struct {
	freq1   uint
	freq2   uint
	attack  uint
	decay   uint
	sustain uint
	release uint
	volume  uint
	channel uint
	mode    uint
}

func (s *Sound) Play() {
	var (
		freq     = s.freq1 | s.freq2<<16
		duration = s.attack<<24 | s.decay<<16 | s.sustain | s.release<<8
		flags    = s.channel | s.mode<<2
	)

	w4.Tone(freq, duration, s.volume, flags)
}

Then it is just a matter of filling in the values from this tool :)

For example this little "blip":

var blip = &Sound{
	freq1:   280,
	freq2:   370,
	attack:  10,
	decay:   0,
	sustain: 4,
	release: 0,
	volume:  8,
	channel: 2,
	mode:    0,
}

Nice!
