This cool new speaker will allow you to play tones, sounds and wave (.wav) sound files from your VEX Cortex. The new speaker plugs into the “SP” port on the Cortex – check near the bottom of the sensor bank of ports. The speaker even has a built in volume control:

 Before you can start using the VEX Speaker with ROBOTC, you must first move the sound files you wish to use onto the Cortex. The sound files must be formatted for 8-bit, 8.000 kHz, Mono output and saved as a .wav (waveform audio file format) file. You can use a free, open source program called Audacity to perform this conversion.
