Easy Audio Interfaces

Easy Audio Interfaces is a Python library that provides a simple and flexible way to work with audio streams, including recording, playback, network transfer, and processing.

Features

• Socket-based audio streaming
• Local file reading and writing
• Audio resampling and rechunking
• Voice activity detection (VAD) using Silero VAD model
• Network file transfer

Quick Start

Here's a simple example to get you started - record audio from a socket, process it, and save to a file:

from easy_audio_interfaces import SocketReceiver, LocalFileSink, RechunkingBlock, ResamplingBlock

async with SocketReceiver() as receiver, LocalFileSink("output.wav") as sink:
    rechunker = RechunkingBlock(chunk_size=512)
    resampler = ResamplingBlock(original_sample_rate=receiver.sample_rate, resample_rate=16000)

    rechunked_stream = rechunker.rechunk(receiver)
    resampled_stream = resampler.resample(rechunked_stream)
    await sink.write_from(resampled_stream)

Advanced Usage: Manual Chunk Processing with ResamplingBlock

For more control over individual audio chunks, you can use process_chunk and process_chunk_last:

from easy_audio_interfaces import ResamplingBlock
from wyoming.audio import AudioChunk

resampler = ResamplingBlock(resample_rate=16000)
await resampler.open()

# Process individual chunks
for chunk in audio_chunks:
    async for resampled_chunk in resampler.process_chunk(chunk):
        # Handle each resampled chunk
        process_audio(resampled_chunk)

# Important: Flush remaining buffered samples
async for final_chunk in resampler.process_chunk_last():
    process_audio(final_chunk)

await resampler.close()

Installation

From PyPI

uv add easy-audio-interfaces

From Source

uv add "https://github.com/AnkushMalaker/python-audio-interfaces.git"

Optional Dependencies

Based on the functionality you require, you should consider installing with the following extras:

# For speech-to-text
uv add "easy-audio-interfaces[stt]"

# For voice activity detection
uv add "easy-audio-interfaces[silero-vad]"

# For Bluetooth audio
uv add "easy-audio-interfaces[bluetooth]"

# For local audio devices
uv add "easy-audio-interfaces[local-audio]"

Usage

Main Components

Audio Sources

• SocketReceiver: Receives audio data over a WebSocket connection
• LocalFileStreamer: Streams audio data from a local file

Audio Sinks

• SocketStreamer: Sends audio data over a WebSocket connection
• LocalFileSink: Writes audio data to a local file

Processing Blocks

• CollectorBlock: Collects audio samples for a specified duration
• ResamplingBlock: Resamples audio to a different sample rate
  • process_chunk_last(): Flushes remaining buffered samples from the resampler. Call this after processing all chunks to ensure no audio data is lost due to internal buffering.
• RechunkingBlock: Rechunks audio data into fixed-size chunks

Voice Activity Detection

• SileroVad: Uses the Silero VAD model for voice activity detection
• VoiceGate: Applies voice activity detection to segment audio

Examples

Basic Friend Recorder

Records voice segments from a network stream using VAD:

python -m easy_audio_interfaces.examples.basic_friend_recorder

File Network Transfer

Transfer audio files over a network:

# Sender
python -m easy_audio_interfaces.examples.file_network_transfer sender input_file.wav --host localhost --port 8080

# Receiver
python -m easy_audio_interfaces.examples.file_network_transfer receiver output_file.wav --host 0.0.0.0 --port 8080
