The iZotope Spire is an oddity and many would be hard-pressed to classify it.

It is labeled an interface by many retailers though it blurs the line between hardware workstation, and portable recorder as well.

Regardless of classification, it enables convenient recording via XLR or the built-in mic.

All recorded files are stored in the hardware but are easily accessed via the mobile app.

Tech Specs:

  • A/D Resolution: 48 kHz/24-bit
  • Connectors: None. Connects via internal WiFi Router
  • Simultaneous Channels: 2
  • Inputs: 2 x XLR/TS combo jacks
  • Outputs: 2 x headphone 1/8" outputs
  • MIDI: none
  • Power: Universal power adapter
  • Bundled Software: Spire Studio Controller app
  • Phantom Power: Yes


People who were browsing for audio interfaces with hopes of getting musical ideas down were drawn to the Spire for the convenience and speed it puts ideas down onto record. Many love the fact that they can easily set it up within seconds and put ideas as they pop up in their heads. As a creative tool, many rave reviews were written about how the Spire enabled them to get ideas down faster, and even more fleshed out with layers thanks to the Spires integrated mixing tools.


It's not for everybody: for the price of a regular audio interface, and other peripherals, the Spire sits up there on price with a modest home studio. For some users who bought the unit, some experienced peaking and clipping particularly with drums, but comments speculate that manual gain staging for the inputs may be a solution. No means to transfer large files by a cable. Many felt this offsets the convenience of the unit itself.


If you're the type to want to get ideas on record as fast as possible without booting up a computer, while also being able to make scratch recordings sound listenable, the Spire Studio is right up your alley.
