Hello to all,
I'm working on processing audio data in Real Time, using windows 8.1 and visual studio 2015n SFML 2.4.0, everything work fine, i can record and save in .wav file, i changed Fs from 44100 Hz to 8000 Hz, in my work the data must be bufferise to 0.01 second in Time (so 80 Samples in ones frame), the problem is i want to read (get data or samples recorded) to process them, something like this:
- start record
- every 0.01 read 80 samples
- store them in a vector[80]
- myfunction(vector[80])
- choosing a time_to_record as a condition to stop the record.
* i tried with the function "onProcessSamples" but every time i get a different result.
Do you have a solution for this issue ? or suggest me another thing that i can record and process in Real time.
my code:
// soundStreamSFML_test.cpp : Defines the entry point for the console application.
//
#include "stdafx.h"
#include <iostream>
#include <SFML/Graphics.hpp>
#include <SFML/audio.hpp>
using namespace std;
// flux audio qui joue un buffer déjà chargé
sf::Int16 myBuff[16000];
long int j = 0;
class ch : public sf::SoundRecorder
{
virtual bool onStart() { return true; }
virtual void onStop() {}
virtual bool onProcessSamples(const sf::Int16* samples, std::size_t sampleCount)
{
unsigned long int count_samples = 0;
// int sample_count = 80;
// long int myBuff[79];
//cout << "sampleCount = " << sampleCount << endl;
cout << "sample_count = " << sampleCount << endl;
for (int i=0;i<sampleCount;i++)
{
if (i % 1 == 0)
{
cout << i <<"\t"<< samples[i] << endl;
}
//myBuff[j++] = samples[i];
// cout <<i << " "<< samples[i] << endl;
//printf("\n%d\t%d", i, samples[i]);
//count_samples = count_samples + 1;
}
/*
if (count_samples + 1 % 80 == 0)
{
count_samples = 0;
return false;
}
*/
return false;
}
};
int main()
{
// chargement d'un buffer audio à partir d'un fichier
//sf::SoundBuffer buffer;
//buffer.loadFromFile("1234_recorded.wav");
ch sbr;
//sbr.setChannelCount(0);
sbr.start();
//
sf::sleep(sf::seconds(10.0f));
//cout << sbr.getChannelCount() << endl;
// initialisation et lecture de notre flux
//wait(1000,0);
sbr.stop();
system("pause");
return 0;
}
