ErTing - AI-Powered Audio/Video Denoising

A powerful, local-first audio/video denoising tool powered by AI. ErTing uses ModelScope's speech enhancement models to remove noise from your audio and video files, delivering clean, professional-quality output.

ErTing (耳听) -- Hear clearly.

Features

Three Interfaces

• CLI - Full-featured command-line interface with unified flags
• GUI - PySide6 desktop app with batch processing, multi-file/directory import
• Web - Flask-based web interface for browser-based denoising

Core Capabilities

• AI-powered noise suppression using ModelScope models
• Supports wide range of audio/video formats (MP3, WAV, MP4, AVI, MOV, M4A, FLAC, OGG, WMA, AAC)
• Automatic format conversion to 16kHz WAV for optimal processing
• Configurable output paths and model selection
• JSON output for automation workflows

Requirements

• Python 3.10+
• ffmpeg (for audio format conversion)
• ModelScope package
• 2GB+ RAM recommended for model loading

Installation

Method 1: Install from PyPI

pip install erting

Method 2: Install from Source

git clone https://github.com/cycleuser/ErTing.git
cd ErTing
pip install -e .

Quick Start

CLI Usage

# Basic denoising
erting input.mp3

# Specify output path
erting -o output_clean.wav input.mp3

# JSON output for scripting
erting --json input.mp3

# Verbose mode
erting -v input.mp3

# Quiet mode (minimal output)
erting -q input.mp3

GUI Usage

erting-gui

The GUI supports:

• Add Files - Select multiple audio/video files at once
• Add Directory - Import all supported audio files from a folder
• Batch Processing - Process all files sequentially with progress tracking
• Auto Naming - Output files default to {original_name}_clean.wav
• Custom Output Dir - Choose a separate directory for all outputs
• Stop/Resume - Cancel processing mid-batch

Web Interface

erting-web

Then open http://localhost:5001 in your browser.

CLI Options

erting [-V] [-v] [-o PATH] [--json] [-q] input [options]

Positional Arguments:
  input                  Input audio/video file path

Options:
  -V, --version         Show version and exit
  -v, --verbose         Enable verbose output
  -o, --output PATH     Output file path
  --json                Output result as JSON
  -q, --quiet           Suppress non-essential output
  --model MODEL         ModelScope model name (default: iic/speech_zipenhancer_ans_multiloss_16k_base)

Python API

from erting.api import denoise_audio, ToolResult

result = denoise_audio(input_path="input.mp3")
print(result.success)    # True / False
print(result.data)      # {'input_path': ..., 'output_path': ...}
print(result.metadata)  # {'version': '0.1.0', 'model': ...}

Agent Integration (OpenAI Function Calling)

ErTing exposes OpenAI-compatible tools for LLM agents:

from erting.tools import TOOLS, dispatch

# Pass TOOLS to the OpenAI chat completion API
response = client.chat.completions.create(
    model="gpt-4o",
    messages=messages,
    tools=TOOLS,
)

# Dispatch the tool call
result = dispatch(
    tool_call.function.name,
    tool_call.function.arguments,
)
