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. ...
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...
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. ...
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...
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. ...
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. ...
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...
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...
I am unsure why this code will not work and what i want it to do is when i click a button(action: buttonclick) i want it to change the two text box's(MyTextLabel & MyTextLabel2) text increment the value "r" by one. here is the code: MainView.h #import <UIKit/UIKit.h> #import <Foundation/Foundation.h> @interface MainView : UIView { ...
What's the PHP verson of this python code? import winsound winsound.Beep(537, 2000) ...
Does anyone know if there is an open source MIDI player / synthesizer library that I can incorporate into my iPhone application? ...
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...
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)...
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...
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...
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...
