Dear， Could help me get the waveform data of wav file？ THX

Hey!

The Wav format is supported on all platforms. What exactly is the problem you are facing? As a starting point you could try the code below which will read in an entire wav file into an interleaved vector.

    auto stream = audio::ifstream("hello.wav");
    auto samples = std::vector<float>(stream.info().num_samples());
    stream >> samples;

include <boost/range/value_type.hpp>

Could I use it in windows with Visual Studio??

marcrambo commented 5 years ago

It seems like you are missing the boost libraries. Boost is a required dependency. Cmake should have triggered an error during configure time about the missing library. Are you using cmake?

You can use Visual Studio 2015 and above.

Hiya.

You need to install the boost libraries and then include them in your VS solution. Here is a guide for windows: https://www.boost.org/doc/libs/1_68_0/more/getting_started/windows.html
