In the upper right corner you can adjust the volume of the sound. To turn off the sound, click on the “fork” again. After that, you will immediately hear the sound of note A. In order to hear it, you need to click on the “iron fork”. Use the Java Sound API, and Math.sin to create the actual wave levels.

It provides you with the audio sample of the highest quality and accurate frequency. nont sin returns a value -1.0 to 1.0, multiplying it by 127 gives you a sine wave with a full scale of one byte -127 to +127, (it's cast to a byte) Keegan Jay. You attach this to whatever it is via the.

The service is available free of charge and without registration. Overview: The tone generator is a practical solution for those who always forget their tuning fork at home. This application recreates the main function, the look and the classic form of the tuning fork. Thanks to the tuning fork, tuning of musical instruments at home has become easy and accessible even to non-professional musicians. When you hit it, the vibration starts which provokes the needed sound. Actually the musical tuning fork is a 'piece of iron' in the form of a fork. This frequency is an international standard for note La or A. Tuning fork generates the constant sound with frequency 440 Hz. It is also needed for glee rehearsals, especially when singing A cappella. Usually it is used for tuning guitars, violins, violas, pianos and many other musical instruments. For this purpose people invented a special tool – tuning fork. Simply enter your desired frequency and press play.

Id recomend using it - there is the pygame.sndarray submodule that allows you to manipulate numbers in a data vector that become a high-level sound object that can be playerd in the pygame.mixer module.
