Hi there,

i have some loops which don‘t have slicepoints
integrated. When i use FL Slicer or Slicex i have to slice them there. Is there a way to batch process folders to add these points automatically or is this a manual job?

Thankyou.

Hi! Great question — adding slice points (a.k.a. transient markers) automatically to loops can save a lot of time, especially if you’re working with large sample libraries. Here's how you can approach batch slicing depending on your tools:

✅ Automatic Batch Slicing (with Tools)
There are tools that can detect transients and apply slice points automatically in batch, which can then be imported into FL Studio Slicer/Slicex with those markers.

1. Audio Editing Software with Batch Processing

• Audacity (free, with scripting options)
  
  
• Adobe Audition
  
  
• iZotope RX (premium, powerful batch processing)
  
  
• Wavelab (good for loop libraries)
  

Workflow (example using iZotope RX or similar):

1. Use a transient detector to automatically mark slice points.
   
   
2. Export markers as part of the audio file (typically embedded in WAV metadata or saved as a .cue or .txt file).
   
   
3. Load the file into FL Slicer or Slicex — they will detect embedded markers.
   

2. Dedicated Slicing Tools
Some tools are built specifically for batch slicing:

• ReCycle by Propellerhead: Slices audio based on transients, saves as .REX files (Slicex supports .REX).
  
  
• [Loop Slicer Max4Live (Ableton)], if you're in Ableton world.
  
  
• Sononym: A smart sample browser with transient detection.
  

Using FL Studio Native Tools
FL Studio itself doesn’t support batch slicing with slice points natively, so you'd have to:

1. Use Edison to detect transients (Tools > Regions > Detect transients).
   
   
2. Manually save sliced samples with markers (slow for batches).
   
   
3. Alternatively, use Slicex’s auto-slice feature when loading samples:
   
   • It can detect transients and place slice points automatically based on energy thresholds (right-click the slicing method in Slicex).
     

Batch Workaround (Semi-Automated)
If you’re comfortable with scripting:

• Use Python + pydub or librosa to analyze audio and detect transients.
  
  
• Export cue points or generate .wav files with slice markers in BWF metadata.
  

TL;DR — Summary
Option Batch Capable? Recommended Use
Slicex (Auto Slice) ❌ (one at a time) Simple, FL-native
ReCycle ✅ Best for .REX slicing
iZotope RX ✅ Pro-level batch transient detection
Audacity (w/ scripting) ⚠️ Free workaround
Custom Python Script ✅ Advanced users only
If you tell me what OS and tools you already use (or are willing to try), I can recommend the most efficient workflow for you!
