Soundboard (EZB)

This soundboard will play audio files through the EZ-B v4 speaker. You may load WAV or MP3 files into the library to have multiple audio files. Use the ControlCommand() scripts to trigger specific audio files.

Main Window

1. Stop Button
This button stops the audio coming from the Soundboard.

2. Clean Button
If audio files are deleted from the tracklist they will leave a blank row. This button removes the blank rows from the tracklist.

3. Clipping Indicator
If the volume level bar is increased too high this indicator will turn red and let you know that the audio is clipping. Clipping is a form of audio distortion where the top and bottom of the sound wave are "clipped" off resulting in lower quality sound at a higher volume.

4. Volume Display
This displays the current volume percentage coming from the Soundboard. This value can be from 1(lowest) to 200% (highest) depending on the volume slider's position.

5. Volume Slider
This slider adjusts the volume of the audio coming from the Soundboard.

6. Track Number Column
This column is where the track number is listed. These numbers are important when using controlCommand() scripts.

7. Tracklist Column
This column is where the track titles (+ file format) are listed. Left-click on this area to add a track to the corresponding numbered row.

8. Track Management Buttons
These buttons play the audio, edit the track to include timed scripts, and delete the track.

Settings

1. Title Field
This field contains the title of the skill. You can change it if you'd like. *Note: Changing the title will also change the title in the controlCommand() associated with this skill.

2. Board Index Drop-down
Use this drop-down to select the board number that your EZ-B v4 represents. Double-check the number in the connection skill.

3. Get Music! Button
If you are connected to the internet, this button links you to the freemusicarchive.org where you can download royalty-free music.

How to Use Soundboard (EZB)

1) Add the Soundboard (EZB) Skill to your ARC project (Project -> Add Skill -> Audio -> Soundboard (EZB)).

2) Click on the skill's Track List then find and add an .mp3 or .wav file to the Soundboard.

3) Ensure you are connected to an EZ-B v4 with the ARC software then press the play button and listen for audio to come out of the EZ-B v4 speaker.

Track Editor

The Track Editor is a unique feature to this skill. It allows you to add scripts to multiple timestamps in the track in order to execute robot movements (or other actions) that correspond with the audio track. Simply right-click on the audio waveform to have access to the following options:

• Add Script Here: Adds a script to the selected timestamp.


• Delete selected script: Deletes the script from the timestamp.


• Play from here: Plays the audio track from the selected position.


• Set selection start: Sets the audio track starting position for the selected timestamp.


• Set Selection End: Sets the audio track finishing position for the selected timestamp.


• Clear Range: Clears any "Start" and/or "End" positions added to the track.


• Delete Selection: Deletes everything in between any set "Start and "End" positions.


• Cut Selection: Cuts everything in between any set "Start and "End" positions.


• Copy Selection: Copies everything in between any set "Start and "End" positions.


• Paste Selection: Pastes everything in between any set "Start and "End" positions.


• Delete Everything Before Here: Deletes the part of the waveform before the selected area.


• Delete Everything After Here: Deletes the part of the waveform after the selected area.


• Actions: Adds Auto Position actions instantly to the track into order to create quick dances and animations.

Code Samples

Every Soundboard ControlCommand() is published in the Cheat Sheet tab. Pressing the Cheat Sheet tab will display the ControlCommands() for all skills, including the Soundboard. To play/stop a track from a script, you would use commands such as:

controlCommand("Soundboard v4", "Track_0")
controlCommand("Soundboard v4", "Track_Random")
controlCommand("Soundboard v4", "Stop")

Requirements

An EZ-B v4 I/O Controller.

Resources

To create your own sound recordings or edits to play in the Soundboard you can use open source audio software such as Audacity. Note that the sound files will have to be saved in .wav or .mp3 format. Here's a community tutorial on using Audactiy for sound clips.

There's a also a community tutorial for using the Soundboard skill in general: here
