Synth Waveform Experiments │ Sound design and Synthesis │ haQ attaQ LIVE ep 11

jakoB_haQ

Interested in learning more about synthesis? I did a live stream earlier today in where we where dissecting synthesizer waveforms with the help of an Oscilloscope, in an attempt to understand them better. An oscilloscope is really handy when dealing with this stuff, because it allows us to have a closer look at whats really going on with a sound.

Interesting episode. Loved this one!

The jaggedy-thingies you see at the onset of wave duty-cycles are called the 'Gibbs Phenomenon'. Depending on the precise shape of these little ripples the synth tries to reduce the 'ringing' artifacts that occur when synthesizing digital waveforms with large discontinuities, such as pulse/square waves and sawtooths.

So these little ripple-things you will probably not see when analyzing a similar analog signal, even though the sound may be completely identical to our ears. DSP is a mysterious world

Awesome Bram! Thank you so much! I'll have a nice read this evening! =D

Well, it's quite boring and nerdy stuff actually. I just happen to know because some time ago I was also wondering what these things were and how they affected the sound. Interesting though is that if you look back at the shapes in Sunrizer you'll notice they managed to suppress them quite well.

So THATS what's wrong with my music
