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.

The app almost made me last for work

I am really surprised this app doesn’t automatically shut off after an hour or so after use. Anyways when it’s on, your speakers don’t work so it essentially shut off my alarm for work at 5am. The reason I got this application was for baby sound monitoring. You think a tired and working parent will always remember to shut this off for much later alarms?

From expensive to subscription

I purchased this app for $150+ a few years back. Now, most of the features are non-usable without a subscription. Completely uncalled for. Had I known then what I know now, I wouldn’t have given them the money. Extremely displeased.

Developer Response ,

Hello System24, SoundMeter X is a separate app from what you purchased previously. Any of our legacy apps that you purchased can still be used indefinitely on compatible versions of iOS. The last update to our legacy apps officially supported iOS 11, but we're not aware of any issues on iOS 12. If you have any other questions or concerns, you are welcome to contact us directly.

Unable to download the older app.

Unable to download the older app that I paid a lot of money for. They want you to pay even more money for the new one. I feel like I was robbed.

Developer Response ,

Hi, Matt. You can still re-download the legacy version of SoundMeter or SoundMeter Pro that you already purchased. Those apps will run indefinitely on versions of iOS up to version 12 (they are incompatible with current beta versions of iOS 13). To re-download them on a compatible version of iOS, please see your list of purchased apps in your App Store account. If you have further questions or concerns, please contact us. Also, if you would like to submit a review of SoundMeter X based on its own merits, we would appreciate that.
