Welcome to the world of speech enhancement with DeepFilterNet! This low complexity framework is designed to enhance full-band audio (48kHz) using deep filtering techniques. Whether you’re aiming to improve audio quality for research purposes or personal projects, this guide will walk you through the essential steps of using DeepFilterNet effectively.
Getting Started with DeepFilterNet
Before diving into the specifics, make sure you have the following prerequisites installed on your machine:
- Rust programming language for the deep-filter binaries
- Python (preferably version 3.8+) for running scripts
- The necessary libraries including PyTorch and torchaudio
Installation Steps
1. Download Pre-Compiled Binary
To suppress noise in your .wav audio files, download a pre-compiled deep-filter binary from the release page. Support is currently limited to wav files with a 48kHz sampling rate.
bash
deep-filter [OPTIONS] [FILES]...
2. Setting Up Your Environment
If you want to use the Python backend for enhanced processing via GPU, follow these steps:
- Install PyTorch and torchaudio using:
pip install torch torchaudio -f https://download.pytorch.org/whl/torch_stable.html
pip install deepfilternet
3. Running the Demo
To run the demo on a Linux system, navigate to the demo directory and execute:
bash
cargo +nightly run -p df-demo --features ui --bin df-demo --release
DeepFilterNet Framework
DeepFilterNet is structured into various modules, making its implementation flexible:
- libDF: Contains Rust code for data loading and augmentation.
- DeepFilterNet: Main code for training, evaluation, and visualization.
- pyDF: Python wrapper for STFT processing.
- ladspa: LADSPA plugin for real-time noise suppression.
You can check out the framework running on various operating systems including Linux, MacOS, and Windows.
Enhancing Noise in Audio Files
Assuming you have noisy audio files that you’d like to enhance, you can specify the input and output directories when executing the Python script. Here’s how to enhance a noisy audio file:
bash
python DeepFilterNet/dfenhance.py --model-base-dir PathToModel --output-dir PathToOutput noisy_audio_file.wav
Troubleshooting Common Issues
While working with DeepFilterNet, you might encounter some issues. Here are some common troubleshooting ideas:
- Error in Audio Format: Make sure your audio files are in .wav format at 48kHz.
- Invalid Model Path: Verify that the model path you specified exists and is correct.
- Library Dependencies: Ensure that all required libraries such as LibTorch and HDF5 are installed successfully.
- Incompatibility with Python Version: Use a compatible version of Python (3.8 or above).
