Case Study | Blast Radio - Live Audio Streaming App

Blast Radio

IoT device capable of streaming lossless audio to the Internet

In this project, the client was already working on an IoT device capable of streaming lossless audio to the Internet. With our technical expertise, we've helped them in convert MVP into scalable micro-services & dockerised architecture.

Migration of Firebase database to MySQL.
Microservice architecture with auto-scaling capacity and hosted them on AWS services like ECS & Lambda.
IoT firmware release system with the support of multiple types and versions.
Configured the Icecast server. https://icecast.org/
Implemented RudderStack as CDP and streamed the data to Amplitude.com, Customer.io, S3 Data Lake, and AWS Personalize
Architected multi-region audio streaming services

Project Highlights

Here are some of the challenges we encountered and the achievements we made throughout the project.

From Firebase to AWS: Scaling for Success

Initially, the MVP is built with a Firebase database and function. But as the user base grows, the cost of Firebase increases. So we migrated the Firebase database into MySQL, and Firebase functions into multiple microservices hosted on AWS with different stacks like ECS and Lambda with Auto scaling & load balancer power.

Multiregional Audio Service

We've developed the multiregional audio service to stream the lossless audio with low latency.

Mobile Application

We modelled the Mobile application in Flutter to manage the stream and listen to other broadcasters' streams.

Firmware Evolution: Versatile IoT Release System

We have a homegrown IoT firmware release system with multiple types of firmware and version support.

RudderStack Powers Multi-Platform Data Streaming

We integrated RudderStack as CDP in Microservices and mobile app to stream the data to Amplitude.com, Customer.io, DataLack, and AWS Personalise.

Admin Tool

We have also set up the admin tool with Retool.io and Metabase.com.
