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: Built-in memory REC MUSIC MANUAL R0 R1 R2 R9 M0 M1 M2 M9 REC microSD MUSIC R0 R1 R2 R9 M0 M1 M2 M9 • 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 the MUSIC folder. Refer to page 32 for more information on connecting the unit to a computer. Handling Audio Files 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.
