Command line tool for batch processing

[MrBeignets]

Hi, I started looking into command line possibilities with Reaper, and I'd like to make a small .bat that takes a list of waves and process them through -batchconvert command.

So far I came up with this:

cd "C:\Program Files\REAPER (x64)"
reaper -batchconvert "C:\xxxx\list.txt"

The issue is that it doesn't load the reaper config, the fx chain remains empty, files are exported through.

I tried calling:
reaper -cfgfile "C:\yyy\REAPER.ini" -batchconvert "C:\xxxx\list.txt"

It doesnt seems to take the config in account

and

reaper -cfgfile "C:\yyy\REAPER.ini"
reaper -batchconvert "C:\xxxx\list.txt"

Which starts reaper batch converter with the proper config but the second command is processed in another unconfigured instance.

Thanks in advance for your help !

I just saw that there's also a log file that is created after the non process

INIT: REAPER 5.211/x64: batch converter loading job file C:\Users\xxx\Desktop\testreaperbatch\filelist.txt
OK

Also calling reaper -batchconvert seems to open a special instance of Reaper where no rpp file is open, which might explain why no prefs are loaded into the batch converter...

Using reaper -batchconvert *will* load the reaper.ini configuration before processing.

It will not however load any .rpp, nor will it load the default batch converter FX chain or configuration.

The batchconverter text file can specify a lot of things in a <CONFIG block:

• <FXCHAIN sub block
• FXCHAIN "fxchainfilename" line (if path specified, full path, otherwise looks in FxChains directory for filename)
• <OUTFMT block (base64 output format)
• SRATE 44100
• NCH 2
• RSMODE modeidx
• DITHER 3 (1=dither, 2=noise shaping, 3=both)
• PAD_START 1.0 (leading silence in sec)
• PAD_END 1.0 (trailing silence in sec)
• OUTPATH "path"

Then of course, if not in the <CONFIG block, each line should be:

filename

or

filename(TAB CHARACTER)output filename

Edit: also, adding more of this to the command line help text.

Hey Justin, I'm trying to write a <CONFIG block but I can't find a proper way to make it work. Right now I have:


<CONFIG> C:\reabatch\vo_test.wav <FXCHAIN>"mycharacter.RfxChain"</FXCHAIN></CONFIG>

Whats the proper syntax, can you write a small example please?

C:\input\file.wav
C:\input\file2.wav
C:\input\file3.wav
<CONFIG
  FXCHAIN "something.RfxChain"
  OUTPATH "C:\output"

(this use of <CONFIG to start a block and > to end a block mirrors the .rpp project format...)

Works on OSX and linux versions (linux headless as well)

who knew! thx...

...not able to get the usage to display with './REAPER -h' however -> cribbing usage from a forum post...

Just a note for anyone else using this feature, the reaper-render.ini file (%APPDATA%\Roaming\REAPER) contains the settings of any render presets you have and is helpful in finding the settings to use in <CONFIG>

This is brilliant! I'm going to start using it to rerender video files that people submit for our Sunday services, and get them all to the same LUFS-I level.

I know this quote is from an old post, so possibly things have changed. But I'm not finding this reaper-render.ini file.

On a side note, does anyone know how to set the bit depth (16, 24, etc.) when using the command line batch process?

command line of Reaper still needs to improve, to be really practically useful.
