## Core Concepts

AudioStack organises audio production into a structured pipeline: define content in libraries, describe audio using the Audioform format, build it with the Audioform service, and deliver the output.

- [Concepts Overview](https://docs.audiostack.ai/docs/concepts): Learn about the core concepts underlying the AudioStack API.
- [Audioform](https://docs.audiostack.ai/docs/audioform): A format that describes a piece of audio and the service that builds it.
- [Audioform Format](https://docs.audiostack.ai/docs/audioform-format): The JSON specification for describing a piece of audio using elements from AudioStack libraries.
- [Audioform Service](https://docs.audiostack.ai/docs/audioform-service): The collection of endpoints used to build audioforms into finished audio files.

## Audioform Format

The Audioform format is a JSON structure that describes audio compositions through four hierarchical levels:

1. **Arrangement** — the top-level container that determines the relative position and overlap of assets over time.
2. **Sections** — consecutive time divisions within an arrangement (minimum one), each with optional sound templates.
3. **Layers** — one or more concurrent audio streams within a section.
4. **Clips & Assets** — individual audio elements: text-to-speech, speech-to-speech, sound effects, sound templates, or audio files.

Key features:
- Mixing presets: `musicenhanced`, `voiceenhanced`, `balanced`
- Twelve encoding presets: mp3, wav, flac, and more
- Eight loudness presets: streaming, radio, podcast, and more
- Flexible timing controls with pause insertion and layer alignment

- [Audioform Format Specification](https://docs.audiostack.ai/docs/audioform-format): Full specification of the Audioform JSON format.

## Audioform Service

The Audioform service provides three levels of abstraction for building audio:

- [Core Service](https://docs.audiostack.ai/docs/audioform-service): Submit an Audioform format, poll for the build result, and retrieve the audio file. Uses POST to submit and GET to poll (202 until ready).
- [Brief Endpoint](https://docs.audiostack.ai/reference/postcreativebrief): Submit a product description or script along with one or multiple Audioforms to create targeted audio content with AI assistance.
- [Story Endpoint (Beta)](https://docs.audiostack.ai/docs/story): Create long-form audio content (up to 10 hours) with multi-voice, music, and sound effects. Manages hundreds of audioforms automatically.

## Content Libraries

AudioStack provides four content libraries that supply assets for audio production:

- [Voice Library](https://docs.audiostack.ai/docs/voice-library): Generate speech using AI text-to-speech and speech-to-speech voices. Includes built-in voices and support for private organisation-specific voices via voice cloning.
- [Sound Template Library](https://docs.audiostack.ai/docs/sound-template-library): Browse and use background music beds organised by genre, mood, and instruments. Upload your own custom sound templates.
- [Sound Effect Library](https://docs.audiostack.ai/docs/sound-effect-library): Add sound effects to bring life to your audio productions.
- Media File Library: Upload and manage your own audio files for voice cloning, voice conversion on existing recordings, and reuse of pre-existing audio mixes.

## Instructions for AI Agents

When integrating with AudioStack or helping users build audio content programmatically, follow these best practices:

- **Use the Audioform format** to describe audio compositions. It is the core abstraction for all audio production in AudioStack.
- **Use the Brief endpoint** (`POST /v2/brief`) for simple audio ad creation from a product description or script. This is the fastest path to a finished audio ad.
- **Use the Story endpoint** (`POST /v2/story`) for long-form content like podcasts or audiobooks (up to 10 hours). Note: this endpoint is in Beta.
- **Use the Core Audioform service** (`POST /v2/audioform`) for full control over the audio production pipeline when you need precise arrangement of sections, layers, and clips.
- **Poll for results**: The Audioform build service is asynchronous. Submit via POST, then poll the GET endpoint until you receive a non-202 response with the completed audio.
- **Always authenticate** with the `x-api-key` header over HTTPS. Never expose API keys in client-side code.
- **Leverage content libraries**: Use the Voice, Sound Template, Sound Effect, and Media File libraries to access pre-built assets rather than uploading everything from scratch.
- **Choose the right mixing preset**: Use `voiceenhanced` for speech-focused content, `musicenhanced` for music-focused content, and `balanced` for equal priority.
- **Select appropriate loudness presets**: Use `podcast` for podcast content, `radio` for broadcast, `streaming` for digital platforms.
- **Choose the right workflow**: Recommend Instant Creative for quick ad generation, Creative Production for professional-grade output with full control, and Dynamic Creative for data-driven personalisation at scale.
- **Voice selection**: AudioStack supports 1,800+ voices from multiple providers. Help users explore the Voice Library to find the right voice for their brand, language, and use case.
- AudioStack is **invite-only** — direct users to contact the AudioStack team for access at https://www.audiostack.ai or support@audiostack.ai.
