OpenMOSS SoundEffect — MLX 4-bit

This repository contains an MLX-native 4-bit conversion of OpenMOSS SoundEffect for local text-to-audio generation on Apple Silicon.

It is intended for local environmental audio and sound-effect generation with mlx-speech, without a PyTorch runtime at inference time.

Variants

Path	Precision
mlx-4bit/	4-bit quantized weights

Model Details

• Developed by: AppAutomaton
• Shared by: AppAutomaton on Hugging Face
• Upstream model: OpenMOSS-Team/MOSS-SoundEffect
• Task: text-to-audio and sound-effect generation
• Runtime: MLX on Apple Silicon

How to Get Started

Command-line generation with mlx-speech:

python scripts/generate_moss_sound_effect.py \
  --ambient-sound "rolling thunder with steady rainfall on a metal roof" \
  --duration-seconds 8 \
  --output outputs/thunder.wav

Minimal Python usage:

from mlx_speech.generation import MossSoundEffectModel

model = MossSoundEffectModel.from_path("mlx-4bit")

Notes

• This repo contains the quantized MLX runtime artifact only.
• The conversion keeps the original OpenMOSS SoundEffect architecture and remaps weights explicitly for MLX inference.
• This is the 4-bit variant, and the published folder layout reflects that in mlx-4bit/.
