- Click play and drag the slider to alter the frequency
- Sound is generated with a sine wave
- Live spectrum display
Back in the early 80’s when I was a young teen, my dad bought me my first computer. It was a Commodore 64 sporting a [then] impressive 64K of memory ( compared to 16 million K in a 16GB computer today ). When you powered it on, you saw a command-line / Basic language interpreter. As a result, the first thing I learned was how to program in Basic. And the first program I wrote was generating sound frequencies, like say… 230hz.
For years I was dissapointed that ActionScript never had this ability, until Adobe finally released it in Flash Player 10. Generating raw frequencies is nothing exciting unless you want to annoy someone or their dog, but it’s the building block to something more exciting – synthesizers, drum machines, sequencers, and electronic music. I’ll post some links later of some developers who have taken this to a whole new level.
