Codec decoder configuration.

Conv-transformer autoencoder that converts tokens back to a 24 kHz waveform. Uses ALiBi positional bias, QK-norm, LayerScale, and weight-normed convolutions.

Fields

dim: usize

Hidden dimension for transformer layers.

n_heads: usize

Number of MHA heads (not GQA).

head_dim: usize

Per-head dimension.

ffn_dim: usize

SwiGLU FFN hidden dimension.

layers_per_block: usize

Number of transformer layers per block.

sliding_windows: Vec<usize>

Sliding window sizes for the 4 transformer block groups.

input_channels: usize

Input conv: channels in (semantic 256 + acoustic 36 = 292).

output_patch_size: usize

Output conv: samples per patch.

sample_rate: u32

Output sample rate in Hz.

semantic_vq_size: usize

Number of semantic VQ codebook entries.

semantic_embed_dim: usize

Semantic embedding dimension (per entry).

acoustic_fsq_dims: usize

Number of acoustic FSQ dimensions.

fsq_levels: usize

Number of FSQ levels per dimension.

norm_eps: f64

RMSNorm epsilon (codec uses 0.01, much larger than backbone’s 1e-5).

qk_norm_eps: f64

QK-norm epsilon for codec attention.
