So, I am often asked, &#8220;Which mic do you recommend?&#8221; The short answer is that you can connect just about any kind of microphone you want to your iPhone, iPad, or Mac through a suitable USB audio interface. The means that choosing a mic must be done with your own specific needs in mind. The suggestions below offer an answer to this question which addresses various needs and budgets. This is not intended to be an exhaustive list, but it is intended to give you an idea of what&#8217;s possible when selecting an external measurement microphone (or at least to make it easier to find something that fits your immediate needs).<\/p>\n\n\n\n<figure class=\"wp-block-image size-full is-resized\"><a

is-style-wide\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">High-bandwidth, High SPL<\/h2>\n\n\n\n<p>Special considerations need to be made when you need to measure extreme acoustic phenomena, such as frequencies above 20 kHz or sound levels above 140 dB SPL.<\/p>\n\n\n\n<p>Measuring high frequencies requires an interface that supports higher sampling rates, as well as analog bandwidth to match. The MixerFace, mentioned above, supports sample rates as high as 192 kHz, which would suggest a maximum theoretical bandwidth approaching 96 kHz. However, in my testing I have found that its analog circuitry supports measurements up to about 40 kHz (with a frequency response drop of around 5 dB by the time it gets that high). Of course, any microphone and preamplifier (preamp) you use also need to accommodate your high frequency needs.<\/p>\n\n\n\n<p>When high SPL&#8217;s are the goal, then the voltage sensitivity of the measurement mic as well as the maximum voltage of both the mic preamp and the USB interface must be taken into account. As an example, consider PCB&#8217;s <a rel=\"noreferrer noopener\" href=\"https:\/\/www.pcb.com\/products?m=377a12\" target=\"_blank\">377A12 1\/4&#8243; microphone capsule,<\/a> which has a nominal sensitivity of 0.25 mV\/Pa and an advertised max sound level (with 3% distortion) of 182 dB and maximum peak sound level of over 194 dB re 20\u00b5Pa. If 182 dB SPL rms is applied to a mic with a sensitivity of 0.25 mV\/Pa, the mic will yield a voltage of about 6.3 V, rms. If the sound is purely sinusoidal (a single frequency), the peak voltage would be about 3 dB higher, or about 8.9 Volts, peak. PCB&#8217;s compatible 1\/4&#8243; preamps support up to 8 Volts, which would prevent you from measuring such high sound levels. If the sound were more complex, the peak-to-rms ratio would be higher and the maximum measurable rms sound level would then be lower, still. However, PCB&#8217;s phantom-powered mic preamp, the <a href=\"https:\/\/www.pcb.com\/products?m=426a14\">426A14<\/a>, which can be used with the 377A12 mic capsule, increases the available voltage to 10 Volts, which may be important to your specific application.<\/p>\n\n\n\n<p>The RME ADI-2 Pro FS R USB Audio Interface, listed below, is the best solution I have found for high frequency, high SPL acoustic measurements with your iPhone, iPad, or Mac. It supports sample rates up to 768 kHz (and analog input circuitry to match) and input voltages up to +24 dBu, or 12.283 Volts. Be aware, however, that an external phantom power supply is required, since the ADI-2 Pro does not supply phantom power. Also, the ADI-2 is not especially portable, but it is possible to pair it with a 12-Volt battery and take the whole setup with you. Note that SignalScope X does, in fact, support 768 kHz sampling on iPhone, iPad, and Mac.<\/p>\n\n\n\n<div class=\"wp-block-group is-vertical is-layout-flex wp-container-core-group-is-layout-8cf370e7
