Metatags (Premium Feature)
Metatags are special text tags that allow you to define some custom settings per block.
- Metatags are defined inside the naming editor.
- You can set metatags for multiple blocks at once and
- You can define multiple metatags for one block, separated by a semicolon (;).
- Metatags will override default render settings.
Defining a metatag
- Make item selection (one or more blocks)
- Run LKC - RenderBlocks - Enter metatag.lua
- Enter desired metatag using formula:
metatag=value
- Click OK or press ENTER
Available metatags (case sensitive):
- ch - number of channels (predefined config/custom number)
- tail - tail value (ms)
- ftail - faded tail (ms)
- loudness - desired output loudness value (-dB)
- limit - limiter value (-dB)
Channel Metatags
| WARNING: Old channel metatags with ! prefix are deprecated but backwards compatible. |
| NOTE: REAPER can actually render file with any number of channels (odd or even) and you can define that inside render settings, or per block using channel metatags. |
| Predefined | Custom (any number - odd or even) |
| ch=mono ch=stereo ch=quad ch=5.1 ch=7.1 | ch=1 ch=2 ch=3 ch=4 ch=5 etc. |
-
Use channel metatags to override how many channels will be in the output file
-
Make sure to fulfill these prerequisites for multichannel files:
-
Tracks needs to be multichannel
-
Folders needs to be multichannel
-
Master track needs to be multichannel
NOTE: Render settings will be handled automatically
Tail Metatags
Render Blocks will consider render settings window value 
for the tail and use it for rendered files by default.
| NOTE: There is a bug currently for default tail and render blocks. Enable tail while on region render matrix/ all project regions setting. After that save render settings and then it should be fine. This bug does not affect adding tail and ftail metatags. |
Besides that you can define two custom tail metatag types - tail and ftail. This is very useful for sounds that have long reverb tails.
The example shows the same sfx rendered with different tail settings.
| ORANGE: no tail metatag RED: tail=2000 GREEN: ftail=2000 |
Fade shape that is used for ftail is shown in the image below and for now cannot be changed.
