Conversion functions

convert function

template <typename Tout, typename Tin,
          typename Tout_traits = audio_sample_traits<Tout>,
          typename Tin_traits = audio_sample_traits<Tin>>
void convert(Tout *out, const Tin *in, size_t size)

Converts audio samples (both formats are known at compile time)

Source code

template <typename Tout, typename Tin, typename Tout_traits = audio_sample_traits<Tout>,
          typename Tin_traits = audio_sample_traits<Tin>>
void convert(Tout* out, const Tin* in, size_t size)
{
    for (size_t i = 0; i < size; ++i)
    {
        out[i] = convert_sample<Tout, Tin, Tout_traits, Tin_traits>(in[i]);
    }
}
