loadaudio

loadaudio is a Python library designed to effortlessly load audio from a variety of sources and convert it to your desired format. Whether you're working with local files, remote URLs, base64 encoded strings, NumPy arrays, or pydub AudioSegment objects, loadaudio provides a simple and consistent interface.

Features

• Versatile Input: Load audio from:
  • Local file paths (.wav, .mp3, etc.)
  • URLs pointing to audio files
  • Base64 encoded audio strings
  • Data URLs (base64 encoded audio embedded in strings)
  • NumPy arrays representing audio samples
  • pydub.AudioSegment objects
• Flexible Output: Convert loaded audio to:
  • pydub.AudioSegment objects
  • NumPy arrays
  • Local file paths (.wav, .mp3, etc.)
  • Base64 encoded strings
  • Data URLs
• Automatic Input Type Detection: In most cases, loadaudio can automatically determine the input type, simplifying your code.
• Handles Common Audio Formats: Supports a wide range of audio formats compatible with pydub.

Installation

pip install loadaudio

Usage

from loadaudio import load_audio
import numpy as np
from pydub import AudioSegment

# Load audio from a file path as a pydub AudioSegment
audio_segment = load_audio("audio.wav", output_type="pydub")

# Load audio from a URL as a NumPy array
audio_numpy = load_audio("https://example.com/audio.mp3", output_type="numpy")

# Load a base64 string or data URL and save as a wav
file_path = load_audio("data:audio/wav;base64,...", output_type="file", output_path="output.wav")

# Load a NumPy array as a base64 string
numpy_array = np.array([1, 2, 3], dtype=np.int16)  # Example data
base64_string = load_audio(numpy_array, output_type="base64")

# Load a pydub AudioSegment and get a data URL
pydub_segment = AudioSegment.from_file("another_audio.mp3")
data_url = load_audio(pydub_segment, output_type="dataUrl")

# Explicitly specify the input type (optional)
audio_from_base64 = load_audio("your_base64_string", output_type="pydub", input_type="base64")
