Detailed Description

Utility function for reading WAV audio files.

Author

Edward A. Lee

This defines functions and data types for importing audio files with the wave audio format. The main function is read_wave_file(), which, given a path to a .wav file, reads the file and, if the format of the file is supported, returns an lf_waveform_t struct, which contains the raw audio data in 16-bit linear PCM form.

This code has few dependencies, so it should run on just about any platform.

To use this, include the following flags in your target properties:

target C {
    files: [
        "/lib/c/reactor-c/util/wave_file_reader.c",
        "/lib/c/reactor-c/util/wave_file_reader.h"
    ],
    cmake-include: [
        "/lib/c/reactor-c/util/wave_file_reader.cmake"
    ]
}

In addition, you need this in your Lingua Franca file or reactor:

preamble {=
    #include "wave_file_reader.h"
=}
