• Output the number of all media and assign it to allCount

--Mute Media Delete

for i = allCount-1,0,-1 do

• Loop backwards from allCount to 0

• Get mute information for each media

if mute then

• If mute is True (muted), continue below

• Delete the Index media of [i]

depthList = reaper.AZ_GetTrackDepthList(0)

• Get the hierarchical information of all tracks in a list and assign it to depthList.

• Get the total number of tracks and assign it to count

track,trackId = reaper.AZ_GetSelectedTrackFirstInfo(0)

• Get the first track and track ID of all selected tracks and assign it to track/trackId

• Loop twice to prevent cases where the hierarchy has changed and deletion has not been possible

for i = count-1,trackId,-1 do

• Loop from the number of tracks to the first track

• Get the number of media for the specified track ID and assign it to allCount.

- Get the child track of the specified track ID and assign it to trackList

・If there are no child tracks, return false to retval.

if allCount == 0 and retval == false then

• If the track has no media and no child tracks

reaper.AZ_DeleteTrackIdSelect(0,i,0)

• Delete a specified track

• Get the track with the specified ID and assign it to track

for e, value in pairs(depthList) do

• Loop the number of times equal to the number of hierarchical lists

if track == depthList[e].Track then

• If the track matches a track in the hierarchical array

reaper.AZ_SetTrackItemDepth(track,depthList[e].Depth)

• Resets the track's hierarchy to its previous state
