# MIX_LoadRawAudio

Load raw PCM data from a memory buffer.

## Header File

Defined in [<SDL3_mixer/SDL_mixer.h>](https://github.com/libsdl-org/SDL_mixer/blob/main/include/SDL3_mixer/SDL_mixer.h)

## Syntax

```c
MIX_Audio * MIX_LoadRawAudio(MIX_Mixer *mixer, const void *data, size_t datalen, const SDL_AudioSpec *spec);
```

## Function Parameters

|                          |             |                                                              |
| ------------------------ | ----------- | ------------------------------------------------------------ |
| [MIX_Mixer](MIX_Mixer) * | **mixer**   | a mixer this audio is intended to be used with. May be NULL. |
| const void *             | **data**    | the raw PCM data to load.                                    |
| size_t                   | **datalen** | the size, in bytes, of the raw PCM data.                     |
| const SDL_AudioSpec *    | **spec**    | what format the raw data is in.                              |

## Return Value

([MIX_Audio](MIX_Audio) *) Returns an audio object that can be used to make
sound on a mixer, or NULL on failure; call SDL_GetError() for more
information.

## Remarks

There are other options for _streaming_ raw PCM: an SDL_AudioStream can be
connected to a track, as can an SDL_IOStream, and will read from those
sources on-demand when it is time to mix the audio. This function is useful
for loading static audio data that is meant to be played multiple times.

This function will load the raw data in its entirety and cache it in RAM,
allocating a copy. If the original data will outlive the created
[MIX_Audio](MIX_Audio), you can use
[MIX_LoadRawAudioNoCopy](MIX_LoadRawAudioNoCopy)() to avoid extra
allocations and copies.

[MIX_Audio](MIX_Audio) objects can be shared between multiple mixers. The
`mixer` parameter just suggests the most likely mixer to use this audio, in
case some optimization might be applied, but this is not required, and a
NULL mixer may be specified.

## Thread Safety

It is safe to call this function from any thread.

## Version

This function is available since SDL_mixer 3.0.0.
