I was playing around with C# code snippet but I kept hearing a clipping sound. I think this is because the phase variable is being set to 0 in the wrong spot.
The phase at the end of the FillBuffer() method is some non zero number. When FillBuffer is called again, the phase is suddenly changed back to zero. This causes the end of one sin wave segment to be out of sync with the next sin wave segment. The sin wave needs to be continuous between FillBuffer calls so no clipping sound occurs.
Moving the phase variable out of FillBuffer and putting it in a scope above makes it retain its value between FillBuffer calls, making the sin wave continuous, and the clipping sound is gone.
For further proof, the demo project "Audio Generator Demo" has the phase variable be one scope above FillBuffer and it does not set phase=0 inside of FillBuffer. If anything, I'm fixing this documentation to match the working demo
We don't use that info for anything, and it generates unnecessary diffs
every time we bump the minor version (and CI failures if we forget to
sync some files from opt-in modules (mono, text_server_fb).
This has been superseded by GDExtension so this code is no longer useful
nor usable.
There's still some GDNative-related stuff in platform export code which
needs to be adapted for GDExtension (e.g. to include GDExtension libraries
in exports).
This makes it easier to spot syntax errors when editing the
class reference. The schema is referenced locally so validation
can still work offline.
Each class XML's schema conformance is also checked on GitHub Actions.
We already removed it from the online docs with #35132.
Currently it can only be "Built-In Types" (Variant types) or "Core"
(everything else), which is of limited use.
We might also want to consider dropping it from `ClassDB` altogether
in Godot 4.0.
- Add a link to the audio generator demo in AudioStreamGenerator
and AudioStreamGeneratorPlayback.
- Mention that signed PCM8 data is expected in AudioStreamSample
(and how to convert unsigned PCM8 to signed PCM8).
