Description

SoundMeter X turns your iOS device into a handheld data-logging sound level meter (SLM), data-logging noise dosimeter, multi-channel data recorder, and real-time analyzer (RTA).

Input signals can be acquired from the current audio input path (iOS automatically selects the audio input path according to which external audio devices, if any, are connected to your iOS device). Sensitivity calibration can also be performed for any audio input device or input channel.

In addition to real-time sound level measurements, SoundMeter can stream raw sound data to audio files, and store acquired sound level data, including date, time, and location, in CSV or TXT (tab-delimited) files, MAT-files, or high-resolution PDF images for later retrieval from your device.

SoundMeter may be downloaded for free from the App Store. The free download includes a sound level meter tool, which supports time exponential weighted sound levels, Lp, with flat frequency weighting and fast time weighting (LpAF). Additional tools and features are offered via auto-renewable subscriptions.

Fantastic, but too pricey.

This app is excellent! It does everything it says, and it does those things well. It would easily be 5 stars… but for the fact that the majority of the app’s features are locked behind an outrageously expensive paywall.

$100 is the price to enjoy full utility from this otherwise superb audio metering app. Should you decide that a fully featured, professional app like this is necessary for your work/passion and worth the price you better be right because you’re going to owe another $100+ in 12 months. That’s right, for all that $ you don’t actually own anything.

Even worse, I suspect (but don’t truly know) that, should your subscription lapse, you‘ll be locked out of saved data that you’d already paid over $100 to create.

Despite all of my complaints, I admit that I’ve been subscribed to the ~$20/yearly basic+ version of this app for longer than I’d care to admit.

That I don’t plan to cancel should say it all. 😕

Developer Response ,

Hello H0LLYW00D99,
Thank you for taking your time to share your thoughts regarding SoundMeter X. We're pleased to know that you appreciate the quality of the app.
If your concern is with ownership, you may be happy to know that we do offer perpetual license versions of SoundMeter as an alternative to the subscription-based SoundMeter X. If you need to always keep the app up to date with the newest features and tools, SoundMeter X may still be your best option.
With respect to your saved data, you will continue to have access to those files in SoundMeter X, even without a current subscription (remember to first transfer them to another device or to the cloud if you choose to delete the app from your device).
If you have further questions or concerns, please feel free to contact us directly.

Accurate sound meter

So I saw a lot of complaints regarding the cost of licensing and others based on folks who feel that they were cheated out of licensing. While I cannot comment on those specifics, remember that Microsoft does the exact same thing with Office 365. The developers have to pay the bills as well.

As for the free version of this app, it does what it says, and does it well. I tested it against an actual sound meter and had readings within 1 dB of each other across a wide spectrum of intensities and frequencies. For most people, I’m sure this accuracy will suffice. The user interface is fairly intuitive and easy to use. It fits the bill for my, especially since the basic version is free.
