# ONNX-based neural fingerprinter. The user supplies an ONNX model whose
# input is a `[1, n_mels, n_frames]` log-mel spectrogram and whose first
# output is a `[1, embedding_dim]` (or `[1, 1, embedding_dim]`) embedding.
# Requires std (we read the model file and feed PCM at runtime).

# AudioSeal-compatible watermark detector. Requires std.

# Install mimalloc as the process-wide #[global_allocator]. Requires std.
# Off by default because libraries should not pick the allocator on behalf of
# downstream binaries; flip this into `default` if you want it always-on.
