What WAV files levels should I use to avoid clipping on WAV Trigger board (firmware 1.34)?

I use a Robertsonics Wav Trigger board sampler to play polyphonicaly
up to 6 WAV files together. Playing all 6 files produce ‘clipping artefacts’
in the funal mix I hear. I know that’s because each individual files sound levels
are too high and should be lowered to avoid this clipping.
Here are the individual MAX sound levels for each of them
measured in Sony Soundforge software:
-15db
-7.5db
-12db
-13db
-10db
-5db

Please tell me how much should I lower these sound levels
to get a secure non-clipping mix on the Wav trigger ?
The best would be a common dB value I could substract on each of them..
Thanks for your help..

You’ll probably have to determine this with testing/experimenting…you can make copies of the files, then modify them. I’d maybe try subtracting 5dB from each and re-try, go more or less if needed…just save each set/version with a diff name and you should be able to get it going

Probably 5dB substracted on each files could do..
I’ll check if Soundforge could be batch modifications on multiple files..
Would help a lot.. When Robertsonics published its first WavTrigger video
using Mellotron wav files as an example it should have stated
what were the wav files max dB levels on its video..

It really depends on the content of your particular sound files. You didn’t mention how you are triggering the sounds. If you’re using the trigger inputs or serial control, you can specify a gain of less than 0dB. If you’re using MIDI, you can reduce the MIDI velocity value. Both of these methods will effectively reduce the volume of each sound instance without needing to modify your sound files. Otherwise, you’ll need to reduce your sound file levels until you eliminate clipping for your particular case. I usually adjust in steps of 3dB.

I’m using the serial input to access the WavTrigger. No MIDI neither switches..
So no MIDI velocity sent to the WT.
You said .. If you’re using the trigger inputs or serial control, you can specify a gain of less than 0dB.. Yes I did readjust the gain using the serial command to do it.. but as you stated somewhere it won’t fix my problem since the clipping is occuring BEFORE the adjustable gain section.. right ? Anyway I just ‘batch converted’ all my wav files in a -3dB directory and also did it for -5dB.. I’ll check which attenuation starts to make a difference in my case.
