Topic: Level Meter App for Android devices

[JK]

Hello!

I am looking for a level meter app for android devices which displays the input of an internal or external microphone in dBFS.

Perhaps somebody can give me a clue?

Thank you!

Searching the app store brings up loads of matches for "sound meter" - but assuming you've done that already, I guess they don't fit the bill.

That's true ...

Because I'm looking for a PPM and not for Sound Level Meter which measures the sound pressure level.

out of curiosity, are you using it in place of level adjustment on a different recorder, or are you feeding the android unit a digital signal? (where I'm headed is dbfs is somewhat related to the ADC and each ADC will have a different threshold for what produces 0 dbfs)

Thank you very much for your answer.

I am trying out recording software for Android devices and I want to avoid clipping.

Every editing software and every digital recorder has a PPM but I haven't found one for Android smartphones.

gotcha.

feeding it a digital signal or analog in on the phone?

Analog from an external microphone (optional: pre-amplifier)

You could record a 1k sine wav. You can visually see the clipping that way.

I was more curious about after that, namely between the preamp and the recording device if you had a separate ADC so you weren't relying upon the phone's but instead just using it as a bitbucket.

and assuming you don't hear distortion on playback of that sample, you'd get a rough approximation of max dbu that the adc chip in question can handle before it overloads. That's beneficial if you have an external preamp and but even if you know the mv/pa of a set of mics then it would give you an idea of how that will pair in terms of avoiding overloading.
