Echo-TTS GGUF + ONNX

Converted model files for the Echo-TTS C++ inference engine.

This repo contains:

• echo-dit.gguf - EchoDiT diffusion transformer weights (F16 GGUF, best quality)
• echo-dit-q8.gguf - EchoDiT diffusion transformer weights (Q8_0 GGUF, near-lossless, lower VRAM)
• onnx/ - S1-DAC autoencoder (ONNX format) for audio encoding/decoding

Converted from Echo-TTS by Jordan Darefsky.

Usage

echo-tts \
  --model echo-dit.gguf \
  --speaker speaker.wav \
  --dac-encoder onnx_models/dac_encoder.onnx \
  --dac-decoder onnx_models/dac_decoder.onnx \
  --text "[S1] Hello world." \
  --output output.wav

Use echo-dit-q8.gguf instead of echo-dit.gguf for lower VRAM usage with near-lossless quality.
