"It’s exciting and fun to have an audio-only platform that can be so spontaneous and spur of the moment. We really like the potential for being able to jump on to share something new, old, planned or improvised, whatever, whenever."

- Deakin of Animal Collective

Simple setup. Simple streaming.

Blast Box uses Wi-Fi to upload any audio to the cloud as an uncompressed .wav file then streams it to listeners in the highest possible quality.

To set up your Blast Box, pair it to your account using Bluetooth then connect to a Wi-Fi network or a mobile Wi-Fi hotspot (you can even use your phone's hotspot).  

Listeners follow you and tune in through the free Blast Radio mobile app.

Blast Box is how you capture and stream your audio.

Blast Radio is where you build your following and be heard. Listeners download the app, follow you, then get notified every time you stream.

If someone doesn't have the app, they can still tune in by visiting your unique web player: blastradio.com/YourUsername.

Easily download past streams and upload to other audio platforms.

All of your past streams are saved as a private archive with unlimited storage just for you.

Download any past stream from your profile and we will email you the lossless .wav file so you can upload it to any platform you choose. Make a podcast, release an NFT, drop an album... it's your content.
