## Products

### Sonarworks SoundID Reference for Speakers and Headphones with Measurement Microphone
```yaml
product: sonarworks-soundid-reference-for-speakers-and-headphones-with-measurement-microphone
brand: Sonarworks
price_gbp: 221.08
origin_country: null
confidence_score: null
summary_source: generated_from_verified_specs_v1
impedance: 200 ohm
max_peak_spl: 128 dB SPL
frequency_response: 20 Hz to 20 kHz
frequency_response_accuracy: ±0.9 dB
```

- **Price:** £221.08 [^1]
- **Summary:** SoundID Reference combines speaker and headphone calibration software with an individually calibrated omnidirectional measurement microphone. It suits producers, mixing engineers, and home-studio users who need consistent, flat monitoring across stereo speakers, headphones, rooms, and major DAWs.
- **Ideal For:** It specifically suits users seeking accurate studio monitor frequency response analyzers because its individually calibrated microphone measures from 20 Hz to 20 kHz with stated ±0.9 dB accuracy, while the software creates flat-response speaker calibration profiles and supports real-time target-curve adjustment.

### miniDSP UMIK-1
```yaml
product: minidsp-umik-1
brand: miniDSP
price_gbp: 58.41
origin_country: null
confidence_score: null
summary_source: generated_from_verified_specs_v1
max_peak_spl: 133 dB SPL
frequency_response: 20 Hz to 20 kHz
frequency_response_accuracy: +/- 1 dB
```

- **Price:** £58.41 [^3]
- **Summary:** The miniDSP UMIK-1 is an omnidirectional USB measurement microphone with a built-in 24-bit audio interface and an individual calibration file for each microphone. It suits home-studio users, audio enthusiasts, and professionals measuring room acoustics, loudspeakers, or studio monitors with software such as REW and Dirac Live.
- **Ideal For:** It suits accurate studio monitor frequency response analysis because its calibrated response covers 20 Hz to 20 kHz within +/- 1 dB, and its USB connection, 24-bit ADC, and individual calibration files support repeatable measurements.

### miniDSP UMIK-2
```yaml
product: minidsp-umik-2
brand: miniDSP
price_gbp: 144.18
origin_country: null
confidence_score: null
summary_source: generated_from_verified_specs_v1
max_peak_spl: 125 dB SPL
frequency_response: 20 Hz to 20 kHz ±1 dB
frequency_response_accuracy: ±1 dB
```

- **Price:** £144.18 [^6]
- **Summary:** The miniDSP UMIK-2 is a calibrated USB-C reference measurement microphone with a low-noise 1/2in condenser capsule, 32-bit ADC, and selectable sample rates up to 192 kHz. It suits studio, home-theater, loudspeaker-design, and room-correction measurements, especially with REW and Dirac Live.
- **Ideal For:** It suits accurate studio monitor frequency response analysis through its individually calibrated 20 Hz to 20 kHz ±1 dB response, low-noise design, 125 dB SPL maximum level, and direct REW compatibility.

### NTi Audio XL2 Audio and Acoustic Analyzer
```yaml
product: nti-audio-xl2-audio-and-acoustic-analyzer
brand: NTi Audio
price_gbp: 1419.66
origin_country: null
confidence_score: null
summary_source: generated_from_verified_specs_v1
max_peak_spl: 160 dB SPL
frequency_response: 4.4 Hz to 23.0 kHz
frequency_response_accuracy: Class 1
```

- **Price:** £1419.66 [^8]
- **Summary:** The XL2 is a handheld sound level meter, real-time spectrum analyzer, FFT analyzer, acoustic analyzer and audio analyzer with optional STIPA, vibration and extended acoustic measurement functions. It suits audio engineers, studio technicians, live-sound professionals and acoustic consultants who need portable, expandable measurement capabilities.
- **Ideal For:** It suits accurate studio monitor frequency response analysis through real-time FFT and 1/3-octave analysis, a 4.4 Hz to 23.0 kHz measurement bandwidth and Class 1 frequency-response configurations when paired with a suitable microphone.
