Three free sound applications

Sound Meter
ABC Apps

The volume level of a device can also be determined by the smartphone in your pocket. Sound Meter is a simple option for measuring sound pressure in decibels. The app can be used to monitor, for example, the volume of ambient noise, but also to explore the performance of your audio system. The app provides information about, among other things, the minimum, average, and maximum sound pressure levels.

Spectroid
Carl Reinke

What happens in the frequency band? Spectroid is a real-time spectrum analyzer that claims to operate over a wide bandwidth. The application can provide important information, for example, whether there is any unnecessary amplification or attenuation in the frequency band. It also (within the limits of the mobile phone microphone) can be used to check the extreme ends of the repeater band.

Frequency Sound Generator
LuxDeLux

What does a specific, precise frequency sound like? You can find out with the Frequency Sound Generator. The app can also be used to check, for example, how low the bass sound of the audio system extends or how high your own hearing is still capable of functioning. The Hertz value and the waveform are both customizable. In addition, the app also functions as an instrument tuner!
