At Âmago Audio, our research-driven approach merges advanced innovation with precision engineering to create high-speed, time-coherent, low-noise microphones that capture sound with extraordinary clarity, ultrasonic frequency response, and a wide dynamic range.
Developed for modern recording, sound design, AI, and immersive applications, our microphones preserve every transient, every texture, and every detail — revealing what conventional microphones leave behind.
At Âmago Audio, we believe precision matters. Incubated by the renowned University of Aveiro, our research-driven approach allows us to push the boundaries of audio innovation, ensuring unparalleled sound fidelity for the most demanding applications. Our cutting-edge designs enhance key parameters like bandwidth, phase response, dynamic range and noise, delivering unmatched clarity and precision.
Why does microphone precision matter? Similar to how a high-quality canvas is critical for creating a masterpiece, capturing sound with utmost clarity is key to producing professional recordings of the highest quality. Many conventional condenser microphones struggle with issues like boominess due to excessive proximity effect, harsh presence peaks, unnatural off-axis coloration, sluggish impulse response, and excessive handling noise. While audio post-processing can refine and enhance, it cannot remedy a flawed initial capture.
With our high dynamic range, high-speed, low-noise, ultrasonic microphones, you begin with the most accurate representation of your source—capturing sound with pristine clarity and extended frequency response. This transparency ensures that whether you're aiming for absolute accuracy, planning to shape the sound later with EQ, compression, or other creative tools, or looking to let the unique character of your preamp shine through, you're always working from the best possible foundation—preserving fidelity throughout the signal chain.
Beyond Hearing. Beyond Limits.
Human pure-tone hearing may appear to stop at 20 kHz — but perception doesn’t. Research has shown that while we can’t consciously detect pure tones above 20 kHz, our auditory system can register timing differences as small as 6 microseconds, influencing how we perceive clarity, localization, and realism.
Studies by Moore (2003), Green & McGill (2016), and Houtsma & Goldstein (1984) confirm that ultrasonic timing cues are part of how we interpret the world of sound — much like how higher video frame rates make motion smoother even when individual frames are imperceptible. This means microphones limited to 20 kHz simply miss an important part of the time domain.
Real-world sounds generate broadband energy and rapid transient edges that extend beyond the bandwidth of conventional microphones. As such, extending the response into the ultrasonic range is necessary to preserve transient precision and micro-timing information essential to tone, presence, and spatial detail.
There’s also growing evidence that we can perceive ultrasonic frequencies through bone conduction, as shown in many medical and psychoacoustic studies — suggesting that energy beyond the nominal hearing band can be felt and experienced.
At Âmago Audio, we integrate these insights directly into capsule and preamp design. Our microphones extend well beyond the conventional audible band to preserve every transient, leading edge, and subtle spatial cue — delivering an audio image that feels alive, dimensional, and immediate.
Most professional small-diaphragm condensers (SDCs) employ diaphragms between 12 mm and 18 mm in diameter. Âmago’s µSDC™ Technology is built around 7.1 mm and 4.1 mm capsules, representing approximately 67% less diaphragm surface area than conventional SDC designs.
Reducing diaphragm size dramatically lowers moving mass, creating an ultra-lightweight assembly that enables near-instant acceleration and deceleration — the fundamental requirement for accurate transient reproduction.
Historically, capsules at this scale were limited by excessive self-noise and relegated to measurement or specialty applications. Âmago is the first to reduce the self-noise of ultra-small diaphragm condensers to the 15–19 dBA range, without compromising headroom or robustness.
Combined with an ultra-wideband internal preamplifier featuring a 1.5 MHz bandwidth, this architecture delivers a level of transient precision, timing accuracy, and impulse fidelity that most SDCs cannot physically achieve.
The result is a microphone that captures even the fastest attacks — cleanly, precisely, and without the traditional noise penalty.
A New Transient Regime: µSDC™
Every platform you post to — YouTube, Instagram, TikTok — compresses audio aggressively. Most use the Opus codec, squeezing bitrates to 128–160 kbps (and sometimes far lower), flattening transients, trimming dynamics, and rolling off the high end. Additional processing — normalization, limiting, gating — reshapes your sound even further.
Most microphones collapse under this treatment: they capture the surface but not the substance, so when the platform strips the fine detail, little remains.
Âmago microphones are built differently. With ultra fast transient response, extended bandwidth, and exceptionally low noise, they capture much more information — so even after compression, what remains still feels alive, immediate, and authentic. The result is translation across devices and platforms: realism, space, and emotion remain intact, from studio monitors to smartphone speakers.

Fast Rise Time
Rise time measures how fast your output changes in response to a fast step input. A higher bandwidth device has a faster rise time.
At Amago Audio, our fastest microphones have a rise time of approximately 8.75 microseconds, which is twice as fast as 98% of microphones in the market. This rapid transient response is crucial because real world sounds are not mere tones, but rather complex impulse waveforms with ultrasonic attacks and decay phases.
Âmago Audio Microphones respond rapidly to these ultrasonic attacks and recover quickly after the decay, ensuring the utmost clarity by preventing time-domain smearing especially when multiple impulses occur in quick succession.

From Whispers to Thunder
From the faintest whisper to the powerful crash of a snare, sound spans an enormous range — and your microphone should, too. Âmago’s Xtended Series microphones deliver a distortion free dynamic range up to 142 dB SPL, with self noise as low as 15 dB. That means we capture both the smallest ambient details and the most explosive performances without distortion, saturation, or compression artifacts.
Many manufacturers inflate dynamic range specs by measuring only the equivalent electrical input or by omitting total harmonic distortion at the stated SPL. We don’t.
At Âmago Audio, dynamic range is measured the right way: using a clean acoustic stimuli applied directly to the complete microphone, accounting for the capsule, diaphragm, and preamp response. The result is a specification that reflects real world performance instead of marketing abstractions.
Perfect Phase. Perfect Space
Phase refers to the time delay in the arrival of different frequencies within a signal. When this delay is uniform across all frequencies, the system exhibits linear phase, preserving clarity, stereo image, and spatial realism. When it doesn’t, detail blurs and the soundscape collapses.
Âmago microphones are engineered for temporal accuracy. By combining a novel wideband Class A preamp with ultra light diaphragms and an acoustically transparent enclosure, our designs maintain consistent time alignment across the entire frequency spectrum. That means minimal group delay, near perfect impulse fidelity, and stable inter channel coherence — critical in stereo arrays, immersive formats, and measurement work.
The outcome is a new standard in sound realism: instruments occupy real space, transients arrive intact, and mixes retain true three-dimensional depth.
Every real-world sound begins as an impulse — a rapid burst of wideband acoustic energy containing attack, tone, and timing. A microphone’s ability to respond to this instantaneous event determines how faithfully it captures reality.
Conventional microphones often exhibit slow rise times and post-attack ringing caused by higher diaphragm mass, grille reflections, and internal acoustic cavities. These effects smear transient detail and blur temporal accuracy.
Âmago microphones react and settle almost instantly. With rise times as fast as 8.75 microseconds, our 35 kHz models outperform over 98% of microphones, preserving transient information with exceptional precision.
Below, a typical 20 kHz omnidirectional microphone shows a sluggish response and delayed settling due to mechanical and acoustic reflections. By contrast, the Âmago O35X delivers a clean, immediate impulse with no trailing oscillation — maintaining fast transients and harmonic detail in precise temporal alignment.
Instant. Precise. Real Impulse
Transparent Mechanical Design
A microphone’s body doesn’t just hold components — it shapes the sound that reaches them. Grilles, cavities, and internal surfaces can reflect energy, producing standing waves, comb filtering, and phase smear that cloud transient detail.
We designed the mechanical structure as part of the acoustic path. Each microphone uses a precision machined stainless steel enclosure, dimensioned to minimize internal volume and eliminate parallel surfaces that cause resonance.
Critical areas are internally damped with tailored materials and surface treatments that absorb residual energy without restricting airflow — allowing sound to dissipate naturally instead of reflecting back toward the capsule. This internal damping, combined with integrated capsule mounting, removes the need for bulky external cages or multi layer grilles, maintaining tonal purity even at extreme SPL.
Every microphone ships with acoustically transparent hydrophobic foam that, when paired with an IP rated XLR cable, provide basic environmental protection with no tonal penalty.
