Liquid AI Releases LiquidCodec, a 74M-Parameter Streaming Audio Codec

Liquid AI released LiquidCodec, a ~74M-parameter streaming speech tokenizer used in its LFM3-Audio-2B and LFM3-Omni-2B models, which converts 24 kHz audio into 12 token streams at 12.5 Hz frames and back. Liquid AI reports best ViSQOL and lowest mel distance on all 8 test sets versus X-Codec 2, NanoCodec and Mimi, with encode RTF 0.0028 and decode RTF 0.0115 on a single CPU thread, though NanoCodec scored higher PESQ (WB) on 7 of 8 sets. Weights are on Hugging Face, with Q4_0, Q4_K_M and Q8_0 GGUF builds for llama.cpp.
