    Sound synthesis, sound design and audio processing - Part 11

    01/14/15 in Sound Synthesis

    In the previous article, we saw how the evolution of polyphony required ─ and, hence, lead to ─ the introduction of computing in the design of sound synthesis devices. We also saw that the arrival of multi-timbrality marked an additional step in the computerization of sound synthesis systems, given the need to use multiple data channels to control…

    In the previous article we saw how a voice is defined in sound synthesis and how it can gather several oscillators without that necessarily meaning that the synthesizer in question is polyphonic.

    In the previous articles we saw what makes up a synthesizer's basic sound chain: Oscillators, followed by filters and an amplifier, plus envelopes to control them. We also saw that an oscillator can produce a sound wave, with more or less harmonics, but always based (as long as it's a periodic wave) on a fundamental sound, whose frequency can, in…

    10/22/14 in Sound Synthesis

    We have started to study the way in which you can create a sound with the aid of a hardware or virtual synthesizer. But, how does sound ─ which is up to now a combination of voltages or binary data packages ─ turn into something you can actually hear?

    Today we'll deal with another element that is essential to sound synthesis: Filters. They are widely used in subtractive synthesis, which is the most widespread form of synthesis, making filters pretty common on a great number of hardware and virtual instruments.

    Today we'll begin our exploration of the different elements that constitute a synthesizer. "It's about time!," I hear some of you say... And it's true, but it's important to have a theoretical background to know what you are doing. Besides, it's not like I forced you to learn any mathematical formulas, now, did I? Which, on the other hand, will pr…

    09/29/14 in Sound Synthesis

    In the previous article, we explored sounds based on waveforms with more or less harmonics, but they all had one thing in common: They were periodic. As we saw, if you refer to periodic cycle, you refer to frequency, and if you refer to frequency, you refer to pitch and...voilà, you have a music note. Today, we'll deal with sounds that aren't peri…

    Journey to the core of sound

    08/29/14 in Sound Synthesis

    Throughout history, humans all around the globe have never stopped diversifying the uses of music ─ ritual, recreational, intellectual, etc. ─ and have produced it using their voices and bodies or through the development and practice of musical instruments. Through the 19th century, the basic methods for creating music were the same: Hitting anima…

    The Fundamentals of Different Synthesis Methods

    09/19/12 in Sound Synthesis

    Many of those who use synthesizers in the modern technological world are not well versed in the basics of different kinds of synthesis. With the ease of computer-based synthesis, any synthesis program can be opened and fiddled around with by ear until something “cool” comes out.
