ReDimNet2 B2 (VoxCeleb2-dev, lm) for MLX
MLX conversion of the official ReDimNet2 b2-vox2-lm.pt checkpoint
(large-margin fine-tuned (recommended)). It produces 192-dimensional speaker
embeddings from 16 kHz mono audio.
Usage
uv add git+https://github.com/avra-m3/speaker-embedding-mlx
import mlx.core as mx
from redimnet2_mlx import load_model
model = load_model("causal/redimnet2-b2-vox2-lm-mlx")
emb = model(mx.array(wav_16k_float32)[None]) # (1, 192)
Parity
Embeddings match the PyTorch reference to 3.9e-06 relative error (worst case, float32, MLX CPU backend). See the parity log.
