Bfd3 Core Library Instant

Heap-allocated strings are a common source of fragmentation and performance issues. The Bfd3 core library provides a fixed-capacity string that lives entirely on the stack (or inside any other object).

bfd3::FixedString<64> filename = "config_";
filename.append("data.bin");
const char* cstr = filename.c_str(); // null-terminated

#include <bfd3/core.h>
#include <cassert>
int main() 
bfd3::FixedString<20> str = "Hello, Bfd3!";
assert(str.size() == 12);
bfd3::MemoryArena arena(4096);
int* data = (int*)arena.alloc(100 * sizeof(int));
data[0] = 42;
return 0;

DAW integration – Core Library can be triggered via MIDI in any DAW, but mixing requires BFD3 player (no raw WAV mixing from Core Library alone without the engine).

Even with a well-designed library like Bfd3, mistakes happen. Bfd3 core library

Combine intrusive containers with pool allocators for zero-fragmentation dynamic objects.

struct Entity : public bfd3::IntrusiveListNode<Entity> 
    float x, y;
    static bfd3::ObjectPool<Entity> Pool;
;
bfd3::ObjectPool<Entity> Entity::Pool(1024); // pre-allocate 1024 entities
Entity* e = Entity::Pool.allocate();
e->x = 100.0f;
// ... use e ...
Entity::Pool.deallocate(e); // O(1), no heap call

BFD3 uses a strict naming schema to map samples to articulations: #include <bfd3/core

[DrumName]_[Articulation]_[VelocityZone]_[Microphone]_v[Version].wav

Example:
Snare14x5.5_Rimshot_Med_Room_v2.wav
