# AdTech Overview

The Audalaxy Adflow is a scalable solution with intuitive tools for managing workflows with audio commercials. Ads are processed in real time and individually tailored for each listener. An advertisement agency with an VAST4 compatible ad server is required.

### Supported Features

1. **Ad Delivery Scenarios**
   * Preroll
   * Midroll
2. **Methods for detecting & triggering ad breaks**
   * **Bitflip (recommended)** — the copyright bit in the MP3 or AAC-ADTS frame header is set to 1 to mark the ad point. Because the marker travels inside the audio data itself, it is frame-precise (\~23–26 ms) and survives streaming and reconnects.
   * **Metadata** — the ad point is announced through stream metadata. Useful when the encoder cannot touch the audio frames.
   * **Beep (legacy)** — an 18 Hz tone in the source signal, detected on our servers. Still supported, but the detection converts the beep into a bitflip anyway, so setting the bit directly is the better path for new integrations.
3. **Ad Server API Compatibility**
   * AdsWizz
   * Adtonos
   * AdAlliance (Smartclip)
   * AdMediationService (AMS)
   * Any VAST4-compatible ad server
4. **Big Data Storage**
   * **Audalaxy-Big Data**
5. **Additional Features**
   * **Real-time configuration** via web interface (e.g., zone\_alias, drift, maxAds, duration, etc.)
   * **IAB TCF v2 compliance**
   * **Listening impression tracking** for marked elements inside streams, even without an ad server (requires Audalaxy-Big Data)
   * **Full integration** with all ad features of the **Audalaxy Audiostreamer**
