Detailed Description

NOTE: This documentation section is a work in progress!

Using std::vector with nom::SoundFileReader

ISoundFileReader fp = new SoundFileReader();
NOM_ASSERT(fp != nullptr);
if(fp == nullptr) {
  NOM_LOG_ERR(NOM_LOG_CATEGORY_APPLICATION,
              "Failed to create audio buffer: out of memory!");
  return;
}
 
if(fp->open(filename, metadata) == false) {
  NOM_LOG_ERR(NOM_LOG_CATEGORY_APPLICATION,
             "Could not load audio from input file:", filename);
  return;
}
 
NOM_ASSERT(fp->valid() == true);
 
// The number of bytes to read into our temporary read buffer in a single
// update cycle
const nom::size_type CHUNK_SIZE = metadata.total_bytes;
 
// Temporary input buffer
std::vector<int16> read_buffer;
 
// Output buffer; the audio samples for audio playback with one of nomlib's
// audio engines, i.e.: OpenAL
std::vector<int16> buffer = nullptr;
 
nom::size_type total_samples_read = 0;
int64 samples_read = -1;
while(samples_read != 0) {
  samples_read = fp->read(read_buffer.data(), CHUNK_SIZE);
 
  auto& samples = buffer;
  samples.insert(samples.end(), read_buffer.begin(),
                 read_buffer.begin() + samples_read);
 
  total_samples_read += samples_read;
 
  if(total_samples_read >= CHUNK_SIZE) {
    break;
   }
