I'm interested in learning how to write the software for audio synthesizers. a friend of mine started on the hardware side for them and, as i have no experience with this type of code.

some where in main:
char value;
char* sname;
sname= new char[20];
for(int i=0;i!=19;i++)
{
cin>>value;
sname[i]=value;
}
I need a stopping case when user press enter array get closed and add '' at the end but how to do that?
I just spent 3 hours writing and debugging 37 lines of code. Is this normal or am I "below average" in coding abilities. I come from a C background and decided to write C++ code that I finally got right as shown below for the specific example:
Code: #include <iostream>
#include <fstream>
#include <string>
#define SPACE_SEARCH 10
using namespace std;
[code].....
I think it was more the learning along the way that consumed atleast 75% of my time for this specific case. But then again, I read that programming always entails learning along the way and so its somehow no excuse for the long time taken in this specific case.
So as a matter of interest, what pace do all of you operate on, on average? i.e. LOC/day, Debugs per day or any other indicator of productivity?
Is there a way to put a mp3 file into a c program without having the windows media player pop up in the background each time you compile the program? I just wanted to input a few seconds of an audio file..

A = P(1 + r/n)nt
//Declared test cases
float principal = 200000.00, annualInt = 0.03;
float years = 10.0;
float calcInterest1(float principal, float years, float annualInt) {
float interest1;
float nt = annualInt*12;
float A = principal+annualInt;//Accrued Amount
interest1 = (A = (principal*(1+years/100))pow(nt));// A = P(1 + r/n)nt
return interest1;
}
Is there any opensource tool which can check the coding style use in a program.
View 2 Replies View RelatedWrite a program that computes how many feet an object falls in 1 second, 2 seconds, etc., up to 12 seconds.
1.Have a procedure called FallingDistance which has one input parameter, seconds, and one output parameter, distance.
2. Compute the distance in feet an object falls using this formula: d = ½ gt2
(where g = 32.2)
3. The main program should call FallingDistance within a loop which passes the values 1 through 12 as arguments.
4. Print a table with seconds and falling distance in feet.
Sample Output (This program has no input)
Seconds Distance
================
1 16.1000
2 64.4000
3 144.9000
4 257.6000
5 402.5000
6 579.6000
7 788.9000
8 1030.4000
9 1304.1000
10 1610
11 1948.1000
12 2318.4000
In C++, the procedure is called a function. Instead of using an output parameter, your C++ function FallingDistance should return a result of type double. This is what I created:
#include <iostream>
#include <cmath>
#include <string>
using namespace std;
const double g =32.2;
double fallingDistance(double);
[Code] ....
which gave me this error:

I am writing a program where all work is done in the class methods. Main is used to call the methods. I need to know how to get a loop to work without any variables in main that can be used outside the methods. This is what I have in main:

I am trying to create an on-line product store. I'm having trouble with setting up the code to correctly acknowledge quantity desired per product item in the shopping cart at check-out. I want to be able to capture multiple impressions/hits/clicks per item and increase the # in the quantity box each time someone clicks on the same item. For example, if product A is clicked 3 times, then the quantity in the shopping cart should show "3". If it's clicked 5 times, it should show "5" and so on ... However, right now, it's showing the product multiple times in the shopping cart with a quantity of "1" for each time the item was clicked. How can I correct this?

View 1 Replies View RelatedI have a RGB STRIP connected to Arduino, when im communicating via Serial. All works great! So next i wanted to make some audio visualisation.. So i found some samples etc.. and then i created the Audio Visualisation via C# using BASS.NET, when R has been BASSes, G medium frequency and B high frequency. But isnt looking good, so i started thinking, what 3 variables in song has can use, but this is bad idea.. I got idea to change to random color when its get "beat" or BASS hit some value. I tryied 4 hours of doing it, searching, programming... But i cant do it...
So, my question is how to detect the beat or just anything event for Audio Visualisation. Best output form WASAPI. Only what i can do is get FFT and Audio Spectrum from WASAPI by BASS.NET, but thats all. My audio skills is so low for this.
I tried playing audio using irrKlang in openGL.But i ended up with some problems.

I'm trying to make a windows-focused , I will make it portable after , audio function that plays sounds according to my midi file. I know there is playsound, but it's not what I desire. I'm curious if Beep plays through the sound card or is similar to printf("a") ? I'm just looking for a low level solution.

View 3 Replies View Relatedwork for a radio station as their webmaster, and we have been looking into online streaming options for the last few months for our website. Pretty much everyone charges a monthly fee for this type of service and I feel like it is something I am capable of doing myself.
At the station we have a computer dedicated to operating the music/talk. On this computer there is a program that ques all the music, ads, ect.. This would be my audio source: Either the program playing all the music, or the computer itself.
The problem I have been pondering all night is how would I access this input source? The only audio input I am familiar with accessing is .mp3 or .wav files. How can I code my program to access this audio the program is producing and stream it to people on the web?

View 1 Replies View RelatedI have problem with this code:
Code:
#include <string>
#include <fstream>
#include <iostream>
#include <cstdlib>
using namespace std;
// multiplier
const double MULTIPLIER = 0.0000001;
[Code] .....
It should cut wav files into smaller pieces using text file .lab (the values multiplied by * 0.0000001 gives time in second. For example, i have such file with recorded yes and no: [URL] ..... and such boundaries [URL] .... It all should be in the same folder, then, after puting "yesno.wav" into command line and press enter it should gives 2 files with yes and no words. But it doesnt - i obtained one file with silent and one short sound. The record is recorded by Audacity, default sample rate 44100, default sample format 16-bit.
I got this code from a wiki that taught me how to make C code that plays audio, and with a few changes I was able to get it to take a command-line argument as the music file name. Here it is
Code:
#include <stdio.h>
#include <stdlib.h>
#include <SDL/SDL.h>
#include <SDL/SDL_mixer.h>
int main(int argc, char *argv[])
[Code] ....
The only problem is, even though I guess it needs to create a window to work with SDL, is there any way you could hide it or something so the user can't see it? I don't really want to see it ( I'm planning on running it from Batch files or C applications as an easy way to play an audio file once ), because if I did, I might as well just use a default audio player instead.
