With WavePad Audio Editor – Masters Edition, you can create high-quality audio recordings and edit and send them to other people to listen to or share. It allows you to record your voice or any other audio that you want to make into a recording, then add effects and send it to your device to play back. It also allows you to record music and add effects to make it into a song. 

The audio effects you can add are the same ones you can use for sending audio to other people. It has many different sound effects to make your recordings sound different. For example, you can add a high pass filter to make your recording sound clearer.
