Trouble wit embedding .wav as header

[Scuf-235B5ECE]

Hello! I get in trouble with embedding my .wav file into binary as C-header. Few words about my surroundings:
-Microsoft Windows [Version 10.0.22621.1194] (win 11)
-Microsoft Visual Studio Community 2019 ver 16.11.26
-MSVC cl ver 19.29.30148 for x86
-raylib 4.5
At first, I try to load file itself:

`

InitAudioDevice();
Sound testZap = {0};
Wave tempW = {0};
tempW = LoadWave("RotateState.wav");
ExportWaveAsCode(tempW, "RotateSound.h");//header really created
//testZap = LoadSound("RotateState.wav"); //it works too!
testZap = LoadSoundFromWave(tempW);
UnloadWave(tempW);
PlaySound(testZap); // I hear my sound

`

Then, I include fresh header to project, then #include it inside .c file and rewrite code:

`

tempW = LoadWaveFromMemory(".wav", RotateSoundData, sizeof(RotateSoundData));//at LOG console I saw "WARNING: WAVE: Failed to load WAV data"
testZap = LoadSoundFromWave(tempW); //actually, sound is empty
UnloadWave(tempW);
PlaySound(testZap);//nothing!

`

I start investigate, what happens:
-debugging tryout: LoadWaveFromMemory -> drwav_init_memory -> drwav_init_memory_ex -> drwav_preinit ...
I can't go deeper, because IDE can't find source files. So drwav_init_memory returns FALSE.
-I try to read my fresh header, that contains wave data, and compare it with hexadecimal representation of .wav file itself:

Look at byte marked blue - it present in file, but absent in header array.

So my question is: how to store resource in binary for minimalistic projects?
Is LoadWaveFromMemory and ExportWaveAsCode is designed to work together? I mean, that ExportWaveAsCode save to header exactly what LoadWaveFromMemory expects.

If you want to experiment with my data: my wav
RotateState.wav
my header:
RotateSound.zip

Thank you for wasting your time for my little trouble!

Hi @Scuf-235B5ECE, ExportWaveAsCode() saves raw PCM samples, so its array isn't a complete WAV file. LoadWaveFromMemory(".wav", ...) expects the RIFF/WAV header too.

The 53,260 bytes in your exported array match the WAV's audio data exactly. After InitAudioDevice(), you can build a Wave directly using the names in your attached header:

Wave tempW = { 0 };
tempW.frameCount = _FRAME_COUNT;
tempW.sampleRate = _SAMPLE_RATE;
tempW.sampleSize = _SAMPLE_SIZE;
tempW.channels = _CHANNELS;
tempW.data = RotateSoundData;

Sound testZap = LoadSoundFromWave(tempW);
PlaySound(testZap);

Skip UnloadWave(tempW) here, it would try to free the header's static array. Use UnloadSound(testZap) when you're finished with the sound.

If you'd rather keep LoadWaveFromMemory(), embed all the bytes of the original .wav file, including its header. The raylib 4.5 exporter only exports the decoded samples.

Thank you @benitoalba !
Of course, it working method, but now I can suggest yet another one:

    unsigned int readByes = 0;
    unsigned char* memfile = LoadFileData("RotateState.wav", &readByes);
    tempW = LoadWaveFromMemory(".wav", memfile, readByes);
    ExportDataAsCode(memfile, readByes, "RotateSound.h"); //this header can satisfy LoadWaveFromMemory()

And now

    tempW = LoadWaveFromMemory(".wav", RotateSoundData, sizeof(RotateSoundData));
    testZap = LoadSoundFromWave(tempW); //now sound is ready
    UnloadWave(tempW);
    PlaySound(testZap);//playing!

Work as planned.
