There are numerous tools out there for musicians, but not many are as versatile, compact, powerful, and affordable as iZotope’s Spire. This handy portable recording studio goes far beyond mobile recording. It’s perfect for those who are hobbyists, professional musicians, touring musicians, music producers, and more. Chock-full of key technical aspects that any beginner or professional audiophile will love, the iZotope Spire could easily be a key component to anyone’s mobile setup. 

Tech Specs

The iZotope Spire comes with a built-in, high quality microphone. In addition, it has two XLR/TS combo inputs with +48 V of phantom power to plug in external microphones. The highest recording sample rate and bit depth is 48kHz/24-bit. Lastly, it has a rechargeable lithium-ion battery that will get you more than four hours of continuous use. If you don’t want to run it on batteries, then you can plug it in using the DC power.

One of the most unique features of the Spire is the “Soundcheck” feature. This ensures that the player doesn’t distort the audio. On the very top of Spire, there’s a “Soundcheck” button. Simply press that, play the loudest part of your song for ten seconds while Spire captures the sound, and it will automatically set the levels for you.

Spire allows you to layer up to eight parts on one song. All of this information syncs wirelessly through WiFi with the free Spire mobile application. You can edit, add effects (such as amps, delays, and reverbs) with zero-latency, and trim your audio directly within the mobile application. Once finished adding effects, editing, and trimming, you’re able to mix your audio. This includes panning your audio from left to right and ensuring you’re getting the right placement of your instruments.

The LED touchscreen allows you to mute, delete, and adjust the volume flawlessly without having to stop your groove.

Once you’ve finished mixing your project, the mobile application allows you to share it with a friend via Google Drive, Dropbox, or iCloud, or upload it to social media.

Build Quality

The Spire is built very well. Each of the buttons have a hard rubber material. The outer protective layer is a heavy duty metal that protects the Spire of any internal hardware damage in case it's dropped. The mesh for the external microphone is metal.

Ease of Use

The iZotope Spire is very much a plug-and-play device. Pull it out of the box, put some batteries in or plug it in, and hit record. Once you’ve recorded a track, the right side of the ring will light up, signifying one track has been recorded. When you record additional layers, the ring will continue to fill up. It’s really as simple as hitting “New Song,” “Record,” and rolling with the punches. As mentioned above, the tracks will record into the mobile application that you will then be able to share with friends or via social media. 

Final Thoughts

Will iZotope’s Spire replace any professional studio gear? No, but will your professional studio gear be as portable and convenient as the Spire? No. This is one of the best tools for a musician of any skill level because of its ease of use and convenience. You never know when that vocal melody, lyric, guitar riff, or rhythm (and even entire song) pops into your head.

If you’re a musician that likes to travel lightly for gigs, then the iZotope Spire is certainly a tool you’ll want to have in your arsenal.
