Sound Byte lets you quickly and easily arrange and play back sound recordings. They're arranged in racks of 75 recordings, each called a cart (just like the old days in broadcast radio with a cart machine). Clicking on a cart, or hitting the hotkey assigned to it on the keyboard, plays the sound. You can have multiple racks, allowing to you organize your sound files by use.

Sound Byte can activate the handshake line on a serial port when a sound is playing - this can be used to control the PTT line on a transceiver to automate transmission.

Sound playback can be directed to either the default sound output device, or a specific device. This allows you to dedicate one output device for ham radio use that will only play the sounds you want - no more accidently playing system sounds over the air.

Please visit the Sound Byte program page for more information about Sound Byte, or visit our download page to get a copy to try out before you purchase it. There's no risk!
