Rocket Streaming Audio Server (RSAS) is a webserver for delivering live streaming audio over the internet. It receives live, compressed audio from a streaming audio encoder and delivers that audio to listeners connected to the server. RSAS was started as a drop-in replacement for Icecast, designed to overcome the performance limitations and other flaws in Icecast discovered while building the Radio Mast streaming audio CDN.
History
RSAS was developed in C++ by Albert Santoni in 2019 after difficulty scaling up the Icecast-based Radio Mast streaming audio CDN and dissatisfaction with the direction of Icecast development.[2][3][4] Development of RSAS followed the release of Rocket Broadcaster, a streaming audio encoder for Windows, in 2016.[5]
Technical Details
RSAS is a webserver for distributing live streaming audio, available on Linux, Windows, and FreeBSD.[6] It implements the HTTP, SOURCE, and HLS protocols, as well as APIs from Icecast to provide compatibility with Icecast-related software, such as encoders. Encoders connect by making an HTTP PUT request to a specific URL called a "mount", and upload live compressed audio. Listeners connect to the same URL using a player that makes an HTTP/HTTPS GET request and receives the live audio as a progressive download instead.
Created as a replacement for Icecast, RSAS is compatible with the configuration file format from Icecast 2.4.[7]
In addition to supporting most Icecast features, RSAS provides additional functionality such as HLS support, improved AAC support, live streaming metadata, and ad insertion.[8][9]
Performance
Touted as a high performance alternative to Icecast and Shoutcast, RSAS claims to support up to 1 million listeners on a server. Benchmarks published in 2022 demonstrate RSAS serving up to 240,000 listeners simultaneously on consumer-class hardware, limited only by CPU power and network bandwidth.[10] As a webserver, RSAS has been demonstrated to serve regular files with speeds equivalent to nginx on Linux.[8]
