Awesome app! Actually it's much better and more flexible than what I've thought. Best ever. There are a couple of things that can make the app even better though. An option for mic calibration and an option for 1/10 and 1/3 octave frequency domain smoothing can really turn it into a professional, practical tool for sound engineering. PS: the green frequency line can't show the level on the red plot (peak) that's a pain. PPS: the default dettings aren't the best. Play around with the settings and soon you have a jaw-dropping analyzer.
It's not bad but it needs a few additions to make it usable; Add a peak hold, or at least a stop so you can see what as going on. The display jitters so much that you cannot read frequencies being displayed - there just isn't time. Add an averaging function. This will also allow a human to read it. Allow larger fonts!
A professional grade app that is as much lab bench test equipment as smartphone hardware can possibly be. Will this replace an ACTUAL studio audio spec-an? No but this is possibly the best substitute when all you have is your phone.
Allows me to measure and recognise day to day background sounds. I do however want to know how to calculate the dB level of negative values (-105 and -65 - it seems we have continuous by noise around 100hz). I should get my acoustics notes back out!
Near excellence. Carl might think to add an alarm triggered by individual setting of a frequency limit. Any noises over -60 db will trigger an alarm for instance. i.e. noises detector for Alexa?
This app was really good on my Nexus 6p, however I have just upgraded to a Pixel 2 XL and the input from the microphone now only shows louder sounds. The noise level appears to be below -100 dB, or more likely it is being filtered. Can you work around this? Or is it maybe a fault in my phone?
- Added DC subtraction to remove bad readings around 0 Hz.
- Fixed a few small bugs.
