Wiki Guide: How to Play Sounds Through a VEX Cortex Speaker

No comments

Back in April, we did an unboxing for the VEX Cortex Speaker which we blogged about, here.

Since then we have had many requests for an updated guide on how to play custom audio files through the Cortex Speakers. Today, the wait is finally over. We have updated our wiki pages to include an in-depth guide on how to convert a sound file into a Cortex-usable format using the open source program, Audacity [link].

Once the file is formatted and downloaded to the Cortex properly, the ‘PlaySoundFile(“filename.wav”)’ command is used to access the audio file and play it through the speaker port (example shown below).


task main()
{

//Play a Sound File (need to use the File Management to Upload First)
PlaySoundFile("1.wav");
wait1Msec(1000);

}

If you are interested in the Cortex Speaker and what can be played through it, check out the VEX forum post about playing Nyan Cat through the VEX Cortex speaker. As an added holiday bonus, how about the 12 Days of Christmas?

We are continually updating and improving all of our support material; if there is anything you think would make ROBOTC more accessible, don’t hesitate to comment below!
