Handling Audio Files
Recorded audio data is saved in a file. The PR7 comes with folders in which you can save
recorded files. Each folder features a predetermined function.
Folder structure
Folders in the PR7 are structured as follows:
•
REC folder
.................. Stores audio files that were recorded on the unit.
•
MUSIC folder
.............. Stores files that were copied from a computer.
PCM, MP3, and WMA files are supported for playback.
This folder is used for playback only. You cannot copy or
divide files in this folder.
•
MANUAL folder
.......... Stores the Reference Manual (this book). This folder is
included only in the built-in memory.
NOTE
• Folders can be created on a microSD card if the card is inserted into the unit.
• The PR7 will recognize audio files transferred from the computer only if they are inside
for more information on connecting the unit to a computer.
About the limitations of files and folders
The size and the number of folders and files are limited.
• The number of files per folder: Up to 99 files
As soon as you start recording the 100th file, an error message will be displayed and
you will be unable to record.
• Maximum file size: 2GB
If recording is extended and its size exceeds 2GB, the PR7 will automatically create
a new file and continue recording.
NOTE
If you plan to record audio of long duration that may end up larger than 2GB, use a
microSDHC card, which can accommodate files of larger size.
About the file naming rules
The PR7 automatically names recorded files in accordance with the file naming rules
shown below.
The name of files that are saved in the REC folder must conform to these rules. Please
note that if you change a file name, the file will no longer be recognized by the REC
folder.
Files using other name formats will be recognized if they are in the MUSIC folder.
About the file format
The PR7 enables you to edit only files in formats that are available recording format
options on the unit.
