SDL_AudioStream(3type)

💖 SDL_AudioStream 💖

okay bestie, real talk: this is a page from the SDL3 DATATYPES corner of the manual, and the star of the show is the type called SDL_AudioStream. let's get into it 🎀

---

✨ NAME ✨

SDL_AudioStream — the opaque handle that represents an audio stream. that's it, that's the name section, she's concise and she knows it 💅

---

🌸 SYNOPSIS 🌸

#include <SDL3/SDL_audio.h>

typedef struct SDL_AudioStream SDL_AudioStream;

yes bestie, it's a typedef and it's opaque, meaning you don't poke at her insides, you just hold her hand and let her do her thing 🫶

---

🦋 DESCRIPTION 🦋

okay so SDL_AudioStream is an audio conversion interface. like, that's the whole vibe. and the way that she does it?? iconic. let me list it out because there's a lot and all of it slaps:

• It can handle resampling data in chunks without generating artifacts, when it doesn't have the complete buffer available. no crunchies, no weird little pops, nothing. she's smooth 💖
• It can handle incoming data in any variable size. she does not care. bring her whatever, she'll take it.
• It can handle input/output format changes on the fly. mid-stream glow-up, no problem 🔥
• It can remap audio channels between inputs and outputs. stereo to mono, mono to stereo, she's flexible like that ✨
• You push data as you have it, and pull it when you need it; the stream will buffer data as needed. so you don't have to have your whole life together before you show up. she'll hold it for you 🥺
• It can also function as a basic audio data queue even if you just have sound that needs to pass from one place to another. lowkey a whole courier service.
• You can hook callbacks up to them when more data is added or requested, to manage data on-the-fly. very main character energy, very "I'll handle it myself" 😌

and here's the bigger picture, bestie: audio streams are the core of the SDL3 audio interface. like, THE core. You create one or more of them, bind them to an opened audio device, and feed data to them — or, if you're recording, consume data from them instead. that's the whole loop. that's the tea ☕💅

⭐ AVAILABILITY ⭐

This struct is available since SDL 3.2.0. so if you're on anything older, no she's not there yet, sorry bestie 😭

and that's the whole page, fr fr!! this one came to you from Simple Directmedia Layer, and she's running version SDL 3.4.18 — so if you see SDL_AudioStream(3type) floating around in the wild, that's just her signature. go make something that sounds good, bestie, you got this 👑💖✨
