Audio Recording Tips
Emagic
Adat Edit 
no “headroom” above 0 decibels – clipping is immediately 
apparent as harsh distortion.
Pay particularly close attention, therefore, to the clip hold 
display on the recording level meter. Compressors and/or 
limiters can help to avoid digital clipping, while helping to 
maintain a high average signal level.
Sampling rate
In Adat Edit you can record with a sampling rate of 
44.1
 kHz. 
As you know, you must maintain this rate for all audio files used 
in the song.
When you master your audio and Midi songs to DAT, you 
should set the recorder to 
44.1
 kHz. This is the standard for 
professional audio production.
If you need to import files recorded at a different sample rate 
into your songs, you can convert the file's sample rate in the 
Sample Edit window with 
Factory > Sample Rate Convert
.
Fragmentation
During normal use, files on a hard drive can become 
fragmented. If a file is deleted, the place that it occupied on the 
hard disk is then freed. The next time a file is saved, this free 
space may be used to store it. If the file is larger than the free 
space, part of the file will be stored at a completely differen t 
location on the drive.Over the course of time, the available free 
blocks may be scattered all over the drive. When files are 
stored, pieces may be scattered accross dozens of locations.
The read/write heads of the hard disk must, therefore, move a 
lot more than on a hard disk that contains files that are hardly 
fragmented. As a result, the transfer rate of data from the hard 
disk is reduced, and the reading of files  (in the case of Adat 
Edit, the playback of audio tracks) can be disrupted. This
