Questions tagged [sound-synthesis]

Periodic electric signals can be converted into sound by amplifying them and driving a loudspeaker with them. One way to do this is to simply add various amplitudes of the harmonics of a chosen pitch until the desired timbre is obtained, called additive synthesis. Another way is to start with geometric waves, which are rich in harmonic content, and filter the harmonics to produce a new sound- subtractive synthesis.

What's wrong with this simple FM synth design?

I'm trying to implement some features of a Yamaha YM3812 sound chip (aka OPL2 http://en.wikipedia.org/wiki/YM3812) in JavaScript using Audiolet (a synthesis library, http://oampo.github.io/Audiolet/api.html) Audiolet allows you to build a…

Using supercollider with python

I want to do some real time sound processing and I heard about supercollider and it looks great, but I want to stick to python as far as 'normal' programming is the issue. Is there any way to load a python script as a module to supercollider or the…

Sound of a rolling ball

I'm looking for the most realistic way of playing sound of a rolling ball. Currently I'm using a Wav sample that I play over and over as long as the ball is moving - which just doesn't feel right. I've been thinking about completely synthesizing the…

Lightweight open source software synth library on pure C (possibly C++). PCM.?

Are there any portable open source libraries that support sample-based synthesis and encapsulate producing and mixing simple PCMs? I really need something minimalistic and decoupled from operating system audio output mechanisms.

Sound Synthesis Framework in C/C++/Objective-C?

I've searched the net but didn't found anything interesting. Maybe I'm doing something wrong. I'm looking for sound synthesis API written on C, C++ or even Objective-C, which can synthesize different types of waves, effects are optional.
