The ProAudio Tools app is an audio measurement tool that allows you to measure sound pressure levels in your environment. The application displays a graph of the sound pressure level in decibels (dB). The graph is divided into different sections, from zero to a maximum, which you can adjust in the settings. The sound pressure level in decibels is a measurement of the sound power of a sound wave. The graph can be saved and shared with other users.
ProAudio Tools allows you to use the application in different ways. You can set the time for which you want to acquire the data, which is a good option for measuring the environment of your audio source. The time can be set in seconds, milliseconds, or in the app itself.
