Preparing 
Your Files
Before you play your music in Scratch 
Live, It is important to rst analyze your 
les.
  The analyze les function processes 
the songs in your library to detect le 
corruption, saves the waveform overview 
to an ID3 tag*, and calculates auto-gain 
and BPM values.
How to Analyze Files
To analyze les run Scratch Live with the 
SL3 disconnected. On the left side of 
the main screen, click the Analyze Files 
button to automatically build overviews for 
all the tracks in your library. 
TIP: You can drag and drop individual 
folders, crates or files onto the Analyze 
Files button to force the building of 
overviews at any time.
About Corrupt Files
If Scratch Live detects a corrupt 
le it will tag it with a corrupt le 
icon:
  It is very important that you delete ANY 
corrupt les from your library as they can 
cause Scratch Live to crash regardless 
if you play the le or not. See “Status 
Icons” on page 27 and “Corrupt File 
Descriptions and Diagnoses” on page 
37.
Whitelabel.
net
The Serato Whitelabel Delivery Network is 
a unique system that allows record labels 
to digitally deliver promotional releases 
directly to DJs.
  To download Whitelabel audio les and 
sign up to receive updates on the latest 
promotional releases, visit whitelabel.net.
Whitelabel Audio Files
Whitelabel.net audio les are a unique 
format (le extension wl.mp3) developed 
by Serato. They are specially prepared for 
use in Scratch Live; pre-analyzed, tagged 
with song and artist info, BPM and album 
art where possible.
  Whitelabel audio les play as high 
quality 320 kbps stereo audio in Scratch 
Live when Rane Scratch Live hardware is 
connected. Without Scratch Live hardware 
connected, or when playing these les 
through other mp3 software and devices, 
they will play as low quality 32 kbps mono 
audio.
  Whitelabel audio les are promotional 
releases from records labels available to 
Scratch Live DJs for free from Whitelabel.
net.
Set Auto BPM
If this option is checked while analyzing 
les, Scratch Live will calculate the 
estimated tempos of your les. If Scratch 
Live is condent that the Auto BPM 
estimate for a le is accurate, it will be 
written to an ID3 tag* in the le. The Auto 
BPM function will not be applied if the 
track already contains BPM information. 
To re-analyze these les and use Auto 
BPM or auto gain on them, drag them 
onto the Analyze Files button. If you 
know your le’s BPM will fall within a 
certain range, use the range drop down 
to avoid double or half value BPMs being 
calculated.
*NOTE: ID3 tags contain data about 
your tracks and are saved inside the 
files. Genre, track name and artist are 
examples of common tag information. 
See “Editing ID3 tags” on page 27.
The Offline Player
The ofine player is a useful tool for 
preparing crates, auditioning tracks, and 
setting cue and loop points. The ofine 
player is available when Scratch Live 
hardware is not connected, and outputs 
through the current default audio device. 
Load a track to the ofine player by 
dragging and dropping onto the Deck, or 
pressing shift+left arrow. If the end of the 
loaded track is reached, the next track in 
the current playlist is played automatically. 
Click the Ofine Player Controls button 
(outlined below) to expand and hide the 
ofine player controls.
For information on rescanning, moving, 
copying, deleting and backing up your 
les, see “File Management” on page 
28.
