A DIY creator has built a Bluetooth-enabled cassette loop recorder that captures Spotify streams to tape in real time, delivering genuinely analog, lo-fi playback with all the saturation and imperfections plugins attempt to emulate.Despite its retro charm and transparent, stainless-steel design, the project requires advanced skills in soldering, PCB design, and analog troubleshooting, making it better suited to dedicated tinkerers than casual listeners, who may prefer off-the-shelf options like the FiiO CP13.

Streaming services deliver decent audio quality straight to our phones and earbuds, but a DIY creator and YouTuber is taking things a step further. Julius Curt, also known as Julius Makes, has built a custom cassette-tape-themed Bluetooth music player.

The concept is clever and simple. The music player receives audio from your phone via Bluetooth, converts it to an analog signal, mixes it down to mono, and feeds it to the record head of a modified cassette deck.

The tape loops around 3D-printed guides and passes a playback head.Audio is then played via a built-in speaker or through headphones. This intricate journey…
