# AEC Audio Processing Module
A Python module for real-time audio processing using WebRTC technology, optimized and maintained by TheDeveloper. This package provides an easy-to-use interface for audio processing capabilities including echo cancellation, noise suppression, and automatic gain control.
## Features
- **Acoustic Echo Cancellation (AEC)**: Removes echo from audio streams
- **Noise Suppression (NS)**: Reduces background noise
- **Automatic Gain Control (AGC)**: Automatically adjusts audio levels
## Requirements
+ swig
+ meson
+ compile toolchain
+ python3
## Installation
You can install the package directly from PyPI:
```bash
pip install aec-audio-processing
```
## Basic Usage
### Simple Audio Processing
```python
from aec_audio_processing import AudioProcessor
# Initialize with all features enabled
ap = AudioProcessor(enable_aec=True, enable_ns=True, enable_agc=True)
ap.set_stream_format(16000, 1) # 16kHz mono
# Process 10ms of audio data
audio_10ms = b'\0' * 160 * 2 # 10ms, 16000 sample rate, 16 bits, 1 channel
audio_out = ap.process_stream(audio_10ms)
# Check if voice was detected
if ap.has_voice():
print("Voice detected!")
```
### Configuration Options
```python
from aec_audio_processing import AudioProcessor
# Initialize with specific features
ap = AudioProcessor(
enable_aec=True, # Echo cancellation
enable_ns=True, # Noise suppression
enable_agc=True, # Automatic gain control
enable_vad=True # Voice activity detection
)
# Set audio format
ap.set_stream_format(
sample_rate_in=16000, # Input sample rate (Hz)
channel_count_in=1, # Input channels
sample_rate_out=16000, # Output sample rate (Hz)
channel_count_out=1 # Output channels
)
# Set reverse stream for echo cancellation
ap.set_reverse_stream_format(16000, 1)
# Set stream delay for echo cancellation
ap.set_stream_delay(50) # 50ms delay
# Check feature status
print(f"AEC enabled: {ap.aec_enabled()}")
print(f"NS enabled: {ap.ns_enabled()}")
print(f"AGC enabled: {ap.agc_enabled()}")
```
