Four-channel projects
* If you want to load these files onto your computer, make sure
that your waveform editing software supports four-channel
files.
Type Structure
STEREOx1
If there is only one stereo channel pair, a stereo WAV file will be created with a name
consisting of the project name and a.wav extension.
STEREOx2
If there are two stereo channel pairs, a folder will be created with a name consisting of
the project name plus an extension of.pjt. In that folder, stereo WAV files will be cre-
ated with names consisting of the channel number and a.wav extension.
Type Structure
4CH
A four-channel WAV file will be created with a name consisting of the project name
and a.wav extension.

Limitations on file size
The R-4 Pro can handle files up to 2 GB in size. If the file size reaches 2 GB during recording, the file is
closed. Then, a new file is created and recording continues. When you finish recording, these files appear
as separate projects.
About BWF
Files created during recording and editing are in BWF (Broadcast Wave Format). BWF files contain
information about the recording time and recording device (EDIROL R-4 Pro) in addition to the data of a
conventional WAV file. Of course, BWF files can be loaded by playback devices or audio editing software
as conventional WAV files.
When the Setup-Mode for “6 Timecode” (p. 66) in the system settings is “OFF,” files are created in WAV
format.
Caution when copying files from your computer
Be aware of the following when copying files from your computer into the R-4 Pro’s internal hard disk.
• The R-4 Pro can only record linear PCM WAV files at sampling frequencies of 44.1, 48, 88.2, 96, or 192 kHz
and bit depths of 16 or 24 bits. It cannot play back any other type of file.
• File and folder names containing double-byte characters (e.g., Japanese) will not be displayed correctly.
• Any files other than WAV files cannot be recognized by the R-4 Pro, and will be ignored.
• Files beginning with “.” (dot) will be ignored.
• You must not copy files larger than 2 GB into the R-4 Pro’s internal hard disk. Doing so will make the R-4
Pro’s operation unstable, and in the worst case might even damage the files in the internal hard disk.
