The "S" in "S16SYS" stands for "signed", the 16 says that each sample is 16 bits long, and "SYS" means that the endian-order will depend on the system you are on. This is the format that avcodec_decode_audio2 will give us the audio in. channels: Number of audio channels. silence: This is the value that indicated silence. Since the audio is signed, 0 is of course the usual value.

If you're using 8-bit WAV file samples, then use the constant AUDIO_S8. If you are using 16-bit WAV file samples, then use the constant AUDIO_S16SYS. AUDIO_S16SYS will automatically match the user's system's byte order, so you don't have to worry about the endianness of the target system! Now, if you're not sure whether or not your samples are 8-bit or 16-bit, simply try …

SDL_AudioSpec - SDL Wiki
https://wiki.libsdl.org/SDL_AudioSpec
A sample frame is a chunk of audio data of the size specified in format multiplied by the number of channels. When the SDL_AudioSpec is used with SDL_LoadWAV () samples is set to 4096. This field's value must be a power of two.

We then call the Init() function at the top of the file. The first thing that does its call Mix_OpenAudio, which starts the audio system. The settings we use are 44.1 kHz, 16-bit, stereo with a 512 byte buffer. You can use other audio formats, but that is the most common. After opening the audio system, we call Mix_AllocateChannels().

- desired->format should be the audio format (`AUDIO_S16SYS`, etc). - desired->samples is the desired size of the audio buffer, in sample frames (with stereo output, two samples--left and right--would make a single sample frame). This number should be a power of two, and may be adjusted by the audio driver to a value more suitable for the hardware.
