Coarse Audio Structure Generation Via Semantic To Codebook Mapping

via “coarse audio structure generation via semantic-to-codebook mapping”

Open-source text-to-audio — speech, music, sound effects, 13+ languages, runs locally.

Unique: Implements a two-stage hierarchical audio codec approach where coarse tokens establish acoustic structure before fine-grained details are added, enabling efficient progressive refinement and potential latency optimization

vs others: Faster than single-pass models for coarse-only use cases; enables streaming or progressive audio output unlike end-to-end TTS systems
