  "title": "LACE: Layer-Wise Compression for Dynamic Frame Rate Codecs",
  "summary": "LACE replaces single shared segmentation boundaries in dynamic frame-rate neural audio codecs with an independent compression step at each quantization layer, plus union alignment and boundary anchors so layer token streams stay duration-consistent for TTS. The cost is added codec complexity: per-layer compression modules and alignment logic must be trained and maintained, and adoption requires integrating the ESPnet3 codec recipe and retraining or fine-tuning the codec and downstream TTS model. It can fail if layer-specific boundaries interact poorly with an existing TTS stack, if reconstruction gains do not transfer to your data domain beyond LibriTTS, or if the alignment mechanisms erode the frame-rate reduction under different speech characteristics.",
  "rationale": "The method is directly relevant to TTS production efficiency and is released in ESPnet3, but its benefits are workload- and domain-dependent, so it should be validated on the reader's own codec and TTS pipeline before adoption.",
