Beginner Digital Synth

I'm looking into writing a audio syntesizer in Java, and was wondering if anybody has any advice or good resources for writing such a program. I'm looking for info on generating raw sound waves, how to output them into a usable form (playing over speakers), as well as general theory on the topic. Thanks guys. ...

Bandlimited waveform generation

I am writing a software synthesizer and need to generate bandlimited, alias free waveforms in real time at 44.1 kHz samplerate. Sawtooth waveform would do for now, since I can generate a pulse wave by mixing two sawtooths together, one inverted and phase shifted. So far I've tried the following approaches: Precomputing one-cycle perfe...

Does anyone know of any C/C++/C# code libraries that do audio synthesizer emulation?

I'm trying to write a software synthesizer that recreates the sounds made by classic synthesizers like the Moog and the DX7. Does anyone know of any code resources for something like this? Thanks. ...

Access sound card or OS synthesizer device in Java

When I try to list Synthesizer devices in Java (1.6.0), I get only one device, Java Sound Synthesizer. I want to use the Synthesizer in the sound card or use any other installed synthesizer, eg. the Microsoft Synthesizer. How can I go about doing that ? If this capability is not inbuilt, is there any open source project that act as front...

MIDI player/synthesizer library for the iPhone

Does anyone know if there is a free/cheap MIDI player/synthesizer library that I can incorporate into my iPhone application? As I understand it the iPhone doesn't have native support for MIDI playback. To work around this limitation I've created a bank of .caf sound samples that I playback myself but I'd really like to improve the im...

Could someone recommend a good and inexpensive software synthesizer which generates really good piano sound (sample-based); support for other instruments is not required. OS: Windows or MacOS. Java interface would be a great asset. ...

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. ...

Making a real-time audio application with software synthesizers

I'm looking into making some software that makes the keyboard function like a piano (e.g., the user presses the 'W' key and the speakers play a D note). I'll probably be using OpenAL. I understand the basics of digital audio, but playing real-time audio in response to key presses poses some problems I'm having trouble solving. Here is t...

Qt4 modular synth editing widget

Hi, I'm about to start writing a GUI for a modular synthesis app (like Alsa Modular Synth, Pure Data, Ingen) that will be used for patch (sound) editing. What I need to do is something like this: So, basically, it's an area where I can draw some rectangles (boxes) that represent synth modules with input and output ports that I ca...

Drawing A Piano

Hello Everyone, I have started working on a software synthesizer (or keyboard). I have decided to use Java because of the available Jfugue API. I am trying to figure out how to go about creating the actual keys (notes) of the keyboard user interface, but I am stuck. I have tried to create an interface by dragging/dropping black and wh...

How would I go about programatically interacting with VST(i) Plugins to synthesize audio?

Take, for example, the VSTi Triforce, by Tweakbench. When loaded up in any VST host on the market, it allows the host to send a (presumably MIDI) signal to the VSTi. The VSTi will then process that signal and output synthesized audio as created by a software instrument within the VSTi. For example, sending an A4 (MIDI note, I believe)...

Objective-C synthesize property name overriding

Hi there, I am trying to understand the purpose of the synthesize directive with property name overriding. Say that I have an interface defined as follow: @interface Dummy ... { UILabel *_dummyLabel; } @property (retain, nonatomic) UILabel *dummyLabel; And in the implementation file, I have: @synthesize dummyLabel = _dummyLabel...

Setting Properties Rundown in Objective C

One of the things I've been struggling with whilst breaking into Objective C programming is understanding how to manipulate properties. I'm perhaps out of my comfort zone using a proper coding language as opposed to scripting languages that I'm used to, so the declaring things in header files and implementation files is confusing me some...

Slight noise problem when changing the volume in my soft synth

Hi, I'm writing a little software synthesizer and it sounds pretty decent except for a slight noise when the volume changes. e.g. while the volume is changing, a sine wave sounds more like a flute, when the volume is constant it sounds bright and pure. As the volume changes pretty much constantly because of the ADSR, this is very annoyin...
