I am entirely new to C++ with just a couple of hours self-teaching, that started yesterday. SO:
I have a uncompressed simple beep.wav file, just about 3 seconds long with a single beeping sound in it.
What I am ultimately trying to achieve is, just to read the file, and at the same time write the binary data, all including: the header, ftm and data or all that is hex readable data and dump it into a simple beep.txt file.
is this possible, in C++? If so, how should I begin reading and dumping the binary file?
I can read the file ~more or less, using the <fstream> class
#include <iostream>
#include <fstream>
int main()
{
ifstream myfile ("beep.wav", ios::in|ios::binary|ios::ate);
if (myfile.is_open())
{
//reading goes here
}
return 0;
}
As mentioned by yzt, you need to know by advance what's in your .wav and in which order. As far as I know, you will have tags, headers and values (samples) as well as compression informations. So, to give a start :
If you know, by example, that the very first thing to do is to read the compression rate, you'll start your reading process by extracting may be a double :
ifstream myfile("beep.wav", ios::in|ios::binary);
double compression_rate;
myfile.read((char*)&compression_rate, sizeof(compression_rate));
// As well as probably the sample rate...
double sample_rate;
myfile.read((char*)&sample_rate, sizeof(sample_rate));
Then, may be, the number of samples :
int nb_samples;
myfile.read((char*)&nb_samples, sizeof(nb_samples));
Then, the values for those samples... (here stored as a vector of double)
vector<double> vect;
vect.resize(nb_samples);
myfile.read((char*)&vect[0], nb_samples * sizeof(double));
Etc...
But again, what the .wav you opened is made of ?
Once you completely master the content, you can go the other way and start writing your own .wav from scratch...
Getting started - and here.
