A new era in low-noise audio recording
Crystal-clear sound with a noise level

as low as 15 decibels.

Studio recording quality
that fits into your coin pocket
Aspen Aura Microphone utilises four combined MEMS microphones in an omnidirectional configuration, capturing a full frequency range of 20 - 24000 Hz at 48kHz sampling frequency. The microphone achieves a noise level of 15dB(A) and handles maximum sound pressure levels up to 122 dBSPL. The microphone solution is patent pending.
Aspen Aura LE Audio Microphone is designed to be weather resistant for robust and easy usage in real life recording situations.
Our engineering journey
Emendion was founded by three engineers from Umeå, Sweden, who share a passion for audio technology. We created the Aspen Aura Microphone to be among the first professional-grade microphones supporting the new Bluetooth LE Audio standard and Auracast broadcasting.

Aspen Fabric Clip
At just 5 grams, the Aspen Aura Microphone clips to your clothing and stays put. Heavier clip-on microphones tend to pull on fabrics, bounce during movement, and shift out of position. The Aspen avoids all of that — it's light enough to wear comfortably throughout a full day without needing to readjust. The clip is adjustable to 4 positions for different mounting options.
Recording any long speech while you forget it’s even there
With up to 5 hours of continuous streaming on a single charge, it's built to last through long meetings, presentations, or a full day of recording without interruption.
The Aspen LE Audio Microphone is coming to Kickstarter.
Back the campaign to be among the first to get one, at an early-bird price.
