For audio lovers, we recommend making an audio spectrum analyzer. This device is necessary in professional equipment and rarely found in home applications. Present - it significantly increases its attractiveness.
The module is a multi-channel drive meter. The whole acoustic band is divided into several bands and in each of them the amplitude of the signal is measured. The system can be used to study the characteristics of the electroacoustic path transmission. It can also be used to test the acoustic properties of rooms in which music is played.
The device is especially recommended to enthusiasts, fans and all users of audio equipment
