Audible

Audible is a Python low-level interface to communicate with the non-publicly Audible API.

It enables Python developers to create their own Audible services. Asynchronous communication with the Audible API is supported.

For a basic command line interface take a look at my audible-cli package. This package supports:

• downloading audiobooks (aax/aaxc), cover, PDF and chapter files
• export library to csv files
• get activation bytes
• add own plugin commands

Requirements

Python >= 3.10

Installation

Standard Installation

pip install audible

Recommended: With Performance Optimizations

Available in audible >= 0.11.0

For significantly better performance (5-100x faster cryptographic operations), install with optional high-performance crypto backends.

Option 1: cryptography (recommended)

Modern, actively maintained, Rust-accelerated library:

pip install audible[cryptography]

Option 2: pycryptodome

Mature, C-based cryptographic library:

pip install audible[pycryptodome]

Option 3: Both (best for development/testing)

pip install audible[cryptography,pycryptodome]

Using uv:

# With cryptography
uv pip install audible[cryptography]

# With pycryptodome
uv pip install audible[pycryptodome]

# With both
uv pip install audible[cryptography,pycryptodome]

# Or run with extras (in project context)
uv run --extra cryptography your_script.py

The library automatically selects the best available provider:

1. cryptography (preferred, Rust-accelerated)
2. pycryptodome (C-based)
3. legacy (pure Python fallback)

Performance improvements with optimized backends:

• 5-10x faster AES encryption/decryption
• 10-20x faster RSA operations
• 3-5x faster key derivation (PBKDF2)
• 5-10x faster hashing (SHA-256, SHA-1)

Provider Overrides (advanced)

Most applications do not need to interact with the crypto layer directly. Prefer configuring providers through high-level APIs such as Authenticator:

from audible import Authenticator
from audible.crypto_provider import CryptographyProvider, set_default_crypto_provider

# Force a specific provider for this authenticator instance
auth = Authenticator.from_file(
    "auth.json",
    password="secret",
    crypto_provider=CryptographyProvider,
)

# Optional: set a process-wide default provider, then reset to auto-detect
set_default_crypto_provider(CryptographyProvider)
...
set_default_crypto_provider()

get_crypto_providers() remains available for internal use, but it is not part of the supported public API.

Optional: High-Performance JSON Backends

Available in audible >= 0.11.0

For improved JSON serialization/deserialization performance (2-5x faster), install with optional high-performance JSON backends.

Option 1: json-full (recommended)

Complete coverage with best performance for all use cases:

pip install audible[json-full]

Includes:

• orjson: 4-5x faster for compact JSON (API responses, metadata)
• ujson: 2-3x faster with indent=4 support (auth files, library exports)

Option 2: json-fast

Optimized for compact JSON only:

pip install audible[json-fast]

Includes:

• orjson: 4-5x faster for compact JSON

Option 3: Individual providers

# orjson (Rust-based, fastest for compact JSON)
pip install audible[orjson]

# ujson (C-based, excellent for pretty-printed output)
pip install audible[ujson]

# rapidjson (C++ based, alternative to ujson)
pip install audible[rapidjson]

Using uv:

# json-full (recommended)
uv pip install audible[json-full]

# json-fast
uv pip install audible[json-fast]

# Or run with extras (in project context)
uv run --extra json-full your_script.py

The library automatically selects the best available provider:

1. orjson (Rust-based, 4-5x faster for compact JSON)
2. ujson (C-based, 2-3x faster with indent support)
3. rapidjson (C++ based, 2-3x faster)
4. stdlib json (always available)

Performance improvements with optimized backends:

• 4-5x faster compact JSON (orjson)
• 2-3x faster pretty-printed JSON (ujson/rapidjson)
• Smart fallback: orjson automatically uses ujson/rapidjson for indent=4

Provider Overrides (advanced)

Most applications do not need to interact with the JSON layer directly. The library automatically uses the best provider. However, you can override:

from audible.json_provider import OrjsonProvider, get_json_provider, set_default_json_provider

# Get auto-detected provider
provider = get_json_provider()
print(f"Using: {provider.provider_name}")

# Force a specific provider
data = {"key": "value"}
orjson = get_json_provider(OrjsonProvider)
json_str = orjson.dumps(data)

# Optional: set a process-wide default provider
set_default_json_provider(OrjsonProvider)
