Creating RAW Sound

[Zarnick Maelstorm]

Hello, I want to know if OpenAL is able to create RAW sound, I want to make a program that creates a sound from a sin curve, is it possible to load OpenAL with a raw buffer, or it has to be from a file?

Thanks.

Short answer : Yes, you can pass a memory resident raw sound sample to
OpenAL.   The date should be 8bit (unsigned chars) or 16bit (signed
shorts).

Long answer : In fact that is the only way to pass audio data to OpenAL.
In many example applications and utility libraries, audio data is retrieved
from a wave file which is loaded into memory and then passed to OpenAL.
There is only one entry point to get audio data to OpenAL and that is
alBufferData which takes a memory pointer to raw sample data and a few
other parameters that tell AL what format the data is (e.g bit depth,
channel count, playback frequency, etc ...)
