First of all thanks for the previous thread, the previous app "Speaker Setup" has some 10k downloads by now after all.
I continued to use the measurement algorithm from "Speaker Setup" for a new app: "Room Acoustics Meter" offers a more technical approach.
Compared to typical Windows programs, I focused on making many measurements at once.
The algorithm automatically determines the microphone position and saves the result without file handling by OK-clicking.
A private listening room can thus be quickly measured very comprehensively with many measurements using a handy Android device. Of course, this is not possible in a concert hall. In my opinion, this advantage has been used far too little in the private sector.
The result can be output as a frequency-dependent sound pressure map, so you can see different room modes immediately.
Frequency response, impulse response (step, smoothed, filtered by frequency, ETC, Schroeder), waterfall diagram, spectrogram and T_60 are also available.
I put another emphasis on reverberation times for low frequencies.
In my opinion, a simple value (T_60 at 65 Hz = x) sometimes does not describe reality reliably enough to derive e.g. damping measures from it. In the app there are therefore filter options for the impulse response and output of the Schroeder curves.
You can see how the T_60 values come about and can better distinguish between artifacts and the physical behavior of the room.
Currently all plugins are unlocked, the app costs nothing. In case of concerns: the app is distributed as a "beta version" via the Google Playstore, so it is checked for malicious code by Google.
"Beta" means that no more bugs have been found on multiple devices by multiple people,
but the software is not yet to be used "in production".
PREREQUISITES
- A calm mind that doesn't get mad at bugs, but thinks about what could be the cause
- Android 5.2 or later on a cell phone or tablet. iOS is unfortunately not supported.
- Access to the Google Playstore - installation runs like a ready-made app except for a few hints.
INSTALLATION
Either check out hifi-apps.com first and then use the _Download_(via_Google_Play)_ link or directly:
Google Play https://play.google.com/store/apps/details?id=com.hifi_apps.ra_meter
WHAT WOULD I BE GRATEFUL FOR?
- Reports where the user guidance is unclear and therefore leads to senseless operating sequences. Please don't think "I should have thought of that", but let us know.
- Crash reports should be sent automatically. It would be nice not to block the app's internet connection because of this.
The app does not access any personal data and the data volume per crash is at most a few kB, usually considerably less.
