Stereo Tool is a de facto standard among audio processors for online streaming, and support for it is built into our Internet Radio Platform. This processor can significantly improve the sound quality of online radio. It is configured using preset files available online; radio owners also share presets in our Telegram channel. Many features are free, while a license key unlocks additional settings. Once you hear the improvement, returning to unprocessed audio may be difficult for both you and your listeners.
We understand how radio and working with audio content are important for the visually impaired and people with other disabilities, so our Internet Radio Control Panel supports screen reader software, audio event identification and other additional features that make it easier for these categories of people to work.
Our internet radio control panel provides an API for almost every function, allowing you to automate tasks and create your own integrations. You can use the API to build scripts for websites, mobile applications, players, and more. The concept is simple: you access a specific panel URL, receive data in JSON format, and use it in scripts written in PHP, JavaScript, or another language. API request authentication is supported. API documentation is available here .
The engine that we use for broadcasting and audio processing is written in C++ and is highly optimized, so the load on the server processor is very low. To run up to 5 radios on one server, you will only need a server with 1 processor core and 1GB of RAM, and on a modern server on a processor, for example, Core i5 13500, you can run up to 300 Internet radios simultaneously. Our product outperforms radios based on Liquidsoap by about 15-20% in terms of CPU performance.
