audixa 0.1.0

Official Python SDK for Audixa AI Text-to-Speech API

Audixa Python SDK

Official Python SDK for the Audixa AI Text-to-Speech API. Production-ready with both synchronous and asynchronous support.

Features

• ✅ Simple API - One-line TTS generation
• ✅ Sync & Async - Full support for both paradigms
• ✅ Type Hints - Complete type annotations (Python 3.10+)
• ✅ Retry Logic - Automatic retries with exponential backoff
• ✅ Rate Limiting - Built-in concurrency control for async
• ✅ File Downloads - Download audio directly to disk
• ✅ Error Handling - Comprehensive exception hierarchy

Installation

pip install audixa

For async file downloads, also install:

pip install aiofiles

Quick Start

Synchronous Usage

import audixa

# Set your API key
audixa.set_api_key("your-api-key")
# Or use environment variable: AUDIXA_API_KEY

# Generate TTS and get audio URL
audio_url = audixa.tts_and_wait("Hello, world!")
print(f"Audio URL: {audio_url}")

# Or save directly to file
audixa.tts_to_file("Hello, world!", "output.wav")

Asynchronous Usage

import asyncio
import audixa

audixa.set_api_key("your-api-key")

async def main():
    # Generate TTS asynchronously
    audio_url = await audixa.atts_and_wait("Hello, world!")
    print(f"Audio URL: {audio_url}")
    
    # Save to file
    await audixa.atts_to_file("Hello!", "output.wav")

asyncio.run(main())

Low-Level API

For more control, use the client classes directly:

from audixa import AudixaClient

# Create client with custom settings
client = AudixaClient(
    api_key="your-api-key",
    timeout=60.0,
    max_retries=5,
)

# Use as context manager
with client:
    # Start generation (non-blocking)
    gen_id = client.tts("Hello, world!")
    
    # Check status manually
    status = client.status(gen_id)
    print(f"Status: {status['status']}")
    
    # List available voices
    voices = client.list_voices()
    for voice in voices:
        print(f"{voice['id']}: {voice['name']}")

Async Client

from audixa import AsyncAudixaClient
import asyncio

async def main():
    async with AsyncAudixaClient(
        api_key="your-api-key",
        max_concurrency=10,  # Rate limit protection
    ) as client:
        # Concurrent generation
        texts = ["Hello", "World", "How are you?"]
        tasks = [client.tts_and_wait(text) for text in texts]
        urls = await asyncio.gather(*tasks)
        print(urls)

asyncio.run(main())

API Reference

Configuration Functions

Function	Description
set_api_key(key)	Set the global API key
set_base_url(url)	Set the API base URL

Synchronous Functions

Function	Description
tts(text, voice_id=None)	Start TTS generation, returns generation ID
status(generation_id)	Check generation status
tts_and_wait(text, timeout=300)	Generate and wait, returns audio URL
tts_to_file(text, filepath)	Generate and save to file
list_voices()	Get available voices

Asynchronous Functions

Function	Description
atts(text, voice_id=None)	Async TTS generation
astatus(generation_id)	Async status check
atts_and_wait(text, timeout=300)	Async generate and wait
atts_to_file(text, filepath)	Async generate and save
alist_voices()	Async get voices

Error Handling

The SDK provides a comprehensive exception hierarchy:

import audixa

try:
    audio_url = audixa.tts_and_wait("Hello!")
except audixa.AuthenticationError:
    print("Invalid API key")
except audixa.RateLimitError as e:
    print(f"Rate limited. Retry after: {e.retry_after}s")
except audixa.TimeoutError:
    print("Generation timed out")
except audixa.GenerationError as e:
    print(f"Generation failed: {e.message}")
except audixa.NetworkError:
    print("Network error occurred")
except audixa.AudixaError as e:
    print(f"General error: {e}")

Exception Reference

Exception	Description
AudixaError	Base exception for all SDK errors
AuthenticationError	Invalid or missing API key
RateLimitError	Rate limit exceeded (429)
APIError	General API error (4xx/5xx)
NetworkError	Connection/network failure
TimeoutError	Request or generation timeout
GenerationError	TTS generation failed
UnsupportedFormatError	Invalid audio format
ValidationError	Invalid input parameters

Audio Format

Note: Currently, Audixa only supports WAV audio output. The SDK is designed for easy extensibility when new formats are added.

# Correct - WAV format
audixa.tts_to_file("Hello", "output.wav")

# Error - MP3 not yet supported  
audixa.tts_to_file("Hello", "output.mp3")  # Raises UnsupportedFormatError

Logging

Enable debug logging to see SDK activity:

import logging

# Enable debug logging
logging.basicConfig(level=logging.DEBUG)

# Or configure the audixa logger specifically
logging.getLogger("audixa").setLevel(logging.DEBUG)

Production Best Practices

1. Use Environment Variables

export AUDIXA_API_KEY="your-api-key"

import audixa
# API key is automatically loaded from environment
audio_url = audixa.tts_and_wait("Hello!")

2. Handle Errors Gracefully

import audixa

def generate_audio(text: str) -> str | None:
    try:
        return audixa.tts_and_wait(text, timeout=120)
    except audixa.RateLimitError:
        time.sleep(60)
        return generate_audio(text)  # Retry
    except audixa.AudixaError as e:
        logging.error(f"TTS failed: {e}")
        return None

3. Use Async for High Throughput

async def batch_generate(texts: list[str]) -> list[str]:
    async with AsyncAudixaClient(max_concurrency=5) as client:
        tasks = [client.tts_and_wait(text) for text in texts]
        return await asyncio.gather(*tasks, return_exceptions=True)

4. Configure Timeouts

client = AudixaClient(
    api_key="your-key",
    timeout=60.0,      # HTTP request timeout
    max_retries=5,     # Retry attempts
)

audio_url = client.tts_and_wait(
    "Long text...",
    timeout=300.0,     # Wait timeout for generation
)
