New Scripts: 4 presets for vertical waveform Peak Display views

[Thonex]

Hi guys,

Really this is all cfillion's code example from this thread, but I decided to make 4 scripts -- 1 for each preset. I find it tedious to mouse around on the Peak Display Setting window while editing... so I made 4 presets with varying degrees of vertical waveform zoom. This is the actual control that is being changed behind the scene... and it doesn't need to even be open:



Here I have a toolbar to change the settings to demonstrate... as well as binding them to key commands (7, 8, 9, and 0 in this case). Of course you can change the values of the gainfactor variables to suit your preferences.

Should this be in ReaPack?



The code is crazy simple... except I would have never found the correct function or variable name without cfillion's help.

Set Peaks Display 1 (0dB)

function Set_Peak_Display_to_0 ()

  local gainFactor = 1 -- 0dB You can substitue your own value here (prefereably between 0-64)
  dB = reaper.SNM_SetDoubleConfigVar('projpeaksgain', gainFactor)
  reaper.UpdateArrange()
  
end

Set_Peak_Display_to_0 ()

Set Peaks Display 2 (9dB)

function Set_Peak_Display_to_9dB ()

  local gainFactor = 2.83 -- 9dB You can substitue your own value here (prefereably between 0-64)
  dB = reaper.SNM_SetDoubleConfigVar('projpeaksgain', gainFactor)
  reaper.UpdateArrange()
  
end

Set_Peak_Display_to_9dB ()

Set Peaks Display 3 (22dB)

function Set_Peak_Display_to_22dB ()

  local gainFactor = 12.6 -- 22dB You can substitue your own value here (prefereably between 0-64)
  dB = reaper.SNM_SetDoubleConfigVar('projpeaksgain', gainFactor)
  reaper.UpdateArrange()
  
end

Set_Peak_Display_to_22dB ()

Set Peaks Display 4 (36dB)

function Set_Peak_Display_to_36dB ()

  local gainFactor = 63.4 -- 36dB You can substitue your own value here (prefereably between 0-64)
  dB = reaper.SNM_SetDoubleConfigVar('projpeaksgain', gainFactor)
  reaper.UpdateArrange()
  
end

Set_Peak_Display_to_36dB ()

My actual first Lua scripts,
I'm no genius, but quarantine took me here.

I started from the script i've found on this thread
thank you Thonex!
The Script might be useful for those people like me that comes from PT.
These two scripts can add or subtract db's to the Peak display scale.
I set em up with 3db steps, but you can change it however you want.

function Add_Peak_Display ()

  Gain = 3 -- db You can put your own value here (Not more than 36db)
  GetGain = reaper.SNM_GetDoubleConfigVar('projpeaksgain', 0) --Get displayed gain
  Gain_Db_log = math.exp( Gain * 0.115129254 ) -- Translate Gain var to Log Scale thanx Xraym blog
  Max_Db_Display = math.exp( (36 - Gain) * 0.115129254 )
    if(GetGain > Max_Db_Display) -- new gain can't be more then 36db
    then
    NEWgain = 63.095732972255 -- Log scale number for 36db
    else
    NEWgain = GetGain * Gain_Db_log --Add gain
    end
  dB =  reaper.SNM_SetDoubleConfigVar('projpeaksgain', NEWgain)
  reaper.UpdateArrange()
--reaper.ShowConsoleMsg(NEWgain.."\n") -- Use it to check log scale

end

Add_Peak_Display ()

function Subtract_Peak_Display ()

  Gain = 3 -- db You can put your own value here (Not more than 36db)
  GetGain = reaper.SNM_GetDoubleConfigVar('projpeaksgain', 0) --Get displayed gain
  Gain_Db_log = math.exp( Gain * 0.115129254 ) -- Translate Gain var to Log Scale thanx Xraym blog
    if(GetGain < Gain_Db_log) -- new gain can't be less then 0db
    then
    NEWgain = 1 --0db log
    else
    NEWgain = GetGain / Gain_Db_log -- subtract desired gain
    end
  dB =  reaper.SNM_SetDoubleConfigVar('projpeaksgain', NEWgain)
  reaper.UpdateArrange()
--reaper.ShowConsoleMsg(NEWgain.."\n") -- Use it to check log scale

end

Subtract_Peak_Display ()

They are pretty simple scripts but i feel like i just hacked a bank account LOL


the reset function you see on the gif is exactly the one that Thonex posted in this thread
