Audio player beginning

[ArakelTheDragon]

Hi to everyone!

First let me thank you for all of your help until now, I managed to solve my problems and am continuing to learn from my mistakes. I would like to start with audio.

I need to build a simple audio player which will play .wav files for now. My idea is simple, the audio file has to be read and sent to the audio processor. I understand that there are different formats because they are just compressed audio, this means I need to de-compress them and send them to the audio processor. Can you please give me some simple C audio .wav example. I need only the most basic parts, because its very hard to figure out the whole code.

Thank you in advance!

Which OS?
Which Compiler?

Are you looking to leverage all the goodies that your current platform provides.
PlaySound function (Windows) | Microsoft Docs

Or are you going really low level and picking the file apart a byte at a time.
WAV - Wikipedia

Windows 10.
GCC with codeblocks MinGW 17.12.

I am looking for the simplest approach, byte by byte should be the correct one. I don't see why this needs to be so complex sometimes.

You make it complicated by trying to do it all yourself, and not making use of established libraries to do all the work for you.

To me trying to use these established libraries is far more complex than building it by myself. They make no sense in a lot of the cases. Seeing pages of code is much worst to me than doing it by myself. This is why I try to learn the core first. I consider these things to be unnecessary complex and cluttered. Normally this should be simple, a function which transfers the file to audio MCU or to a buffer for the audio MCU, only 1 function is enough, why is it necessary to build such a long code for nothing? 1 function to decompress the audio file and 1 to send it to the audio MCU.

Here is the first error:

#include <windows.h>
#include <mmsystem.h>                               // Necessary for PlaySound ().
#include <iostream>
#include <inttypes.h>                               // Necessary for format identifiers like %llu, %lld and etc. %llu can be replaced with %I64u.
#include <tchar.h>
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <stdbool.h>
#include <math.h>                                   // For iQuadraticEquation (void).

error:
obj\Release\main.o:main.cpp|| undefined reference to `PlaySoundA@12'|

Link to the library that provides PlaySoundA@12

It should be one of these is what I found on the internet?

#include <windows.h>

#include <mmsystem.h> // Necessary for PlaySound ().
#include <iostream>

EDIT: OK my mistake, the library is Winmm.dll, its added and the playing of .wav files works correctly.

1. Answer to how to add library: Why dose this not work? - C++ Forum
2. Library download: Download Winmm.dll for Windows 10, 8.1, 8, 7, Vista and XP - 32 Bit and 64 Bit
3. Instructions on adding the library: c++ - How do I link to a library with Code::Blocks? - Stack Overflow

Sorry for the double post.
Here is the link for .mp3 and other formats. It gives good explanations.
