constexpr EncodeStateFlags carb::audio::fEncodeStateFlagNoExpandBuffer = 0x00000001

Avoid expanding the target SoundData if it runs out of space.

The encoder will simply start to fail when the buffer is full if this flag is used. Note that for some formats this may cause the last block in the stream to be missing if the buffer is not block aligned in size.
