Hello, having a weird problem and wondering if someone can help me.. Basically, I'm trying to read in a .wav file, and I have read in the header information and that's all fine, it's just the data..
Here is the code:
bool Wav::readHeader(ifstream &file)
{
file.read(this->chunkId, 4);
file.read(reinterpret_cast<char*>(&this->chunkSize), 4);
file.read(this->format, 4);
file.read(this->formatId, 4);
file.read(reinterpret_cast<char*>(&this->formatSize), 4);
file.read(reinterpret_cast<char*>(&this->format2), 2);
file.read(reinterpret_cast<char*>(&this->numChannels), 2);
file.read(reinterpret_cast<char*>(&this->sampleRate), 4);
file.read(reinterpret_cast<char*>(&this->byteRate), 4);
file.read(reinterpret_cast<char*>(&this->align), 2);
file.read(reinterpret_cast<char*>(&this->bitsPerSample), 4);
char testing[4] = {0};
int testingSize = 0;
while(file.read(testing, 4) && (testing[0] != 'd' ||
testing[1] != 'a' ||
testing[2] != 't' ||
testing[3] != 'a'))
{
file.read(reinterpret_cast<char*>(&testingSize), 4);
file.seekg(testingSize, std::ios_base::cur);
}
this->dataId[0] = testing[0];
this->dataId[1] = testing[1];
this->dataId[2] = testing[2];
this->dataId[3] = testing[3];
file.read(reinterpret_cast<char*>(&this->dataSize), 4);
this->data = new char[this->dataSize];
file.read(data, this->dataSize);
unsigned int *te;
te = reinterpret_cast<int*>(&this->data);
cout << te[3];
return true;
}
Now if I use the readwav in Matlab I get the result (of the third element, same file): -0.0078 But in the C++ output I get 1031127695
I have heard it's something to do with the fact I'm outputting it as an integer, but I've tried every data type there is.
Any ideas? Thanks :)
