How do I make a sound continuously play when pressing keys?

can someone help me how I can have a sound continuously playing when pressing keys

function inputStart(obj, gameProcessed, plr) 
    if gameProcessed then return end
    local equiped = player.Character:FindFirstChild(script.Parent.Name)
    if obj.KeyCode == Enum.KeyCode.W then
        if equiped then        
            Up:Play()
            Left:Stop()
            Down:Stop()
            Right:Stop()
            script.Parent.Sound:FireServer() -- Sound Plays
            wait(.5)
            script.Parent.SoundStop:FireServer() -- Sound Stop
        end
    elseif obj.KeyCode == Enum.KeyCode.A then
        if equiped then
            Left:Play()
            Up:Play()
            Down:Stop()
            Right:Stop()
            script.Parent.Sound:FireServer() -- same Sound Plays
            wait(.5)
            script.Parent.SoundStop:FireServer() -- same Sound Stop
-- Code that continues... It's the same thing
        end

Whenever .5 ends, the sounds just have a seizure when I spam keys. I need to find out how to reset wait() or keep the sound playing when spamming keys

If you go to 'Properties' in the Sound, you have an option called 'Loop'. Enable the loop option to continuously play the sound when enabled.
