# Mediaflow Services

## Audiostreamer

Audalaxy Audiostreamer is a live streaming platform service for audio content own-developed by Audalaxy. It is written in a modern programming language that enables all advantages of cloud infrastructures. The software can stream in the following protocols, with ad insertion capability:

* ICY streams (MP3, AAC with included metadata)
* RAW Streaming (MP3, AAC without metadata)
* HLS streams

### **Features:**

* HTTP / HTTPs Audiostreaming
* Supports streaming ICY live streams
* Supports a variety of media formats as input
* Supports various ingestion methods (PUSH, RELAY)
* Secure token content protection
* Authenticated connections
* Data aggregations for Big Data analysis
* Automatic stream fallback to a second broadcast route or a cloud playout

### **Ad-Features:**

* Detecting ad break markers via metadata, flipbit (beep)
* Replacement of the original content with digital ads or an insertion of digital ads
* Full individual ad configuration per stream connection via tokens and parameter, e.g. personalized for a user, for individual aggregators, apps, etc.
* Ad break opener and closer before and after ad insertion
* Stream opener for promoted streams
* Keep back spots via token
* Volume adjustments of spots
* Ad insertion capabilities (VAST4)
* All Features from Audalaxy-Adflow

## Metaflow

The Metaflow is a scalable solution with easy-to-use APIs for workflows with audio metadatas. The metadata will be synchronized inside the audio stream as essential part of general system in real time for a channel in general and a unique listener session. This allows metadata to be aligned with individual listener delays by inserted ads. Inside the metadata different types of information can be transported, e.g. title, artist or cover, but also control commands and opportunities to show commercials. If use the Audalaxy-Playoutflow, then the Metaflow is fully integrated
