When Making Important Recordings
Because the recording system using the REAC driver consists of multiple elements (the computer, the
operating system, various drivers), there can be various reasons why recording does not occur correctly.
Some possibilities are that a specific element might not be working correctly, the overall system might have
insufficient performance, the settings might not be appropriate, the system was not operated correctly, or
some other reason. In addition, the recording system will be affected by the environment in which it is located
(the power supply, sound pressure level, vibration, temperature, etc.), and these factors may cause it to
operate incorrectly.
Please carefully read the following cautions.
Check carefully before you make an important recording.
On the day before the actual recording or during the rehearsal, check to make sure that recording occurs
correctly.
Use an additional recording device to record simultaneously (Backup recording).
As a precaution against dropouts or stoppages on the main system during recording, be sure to use an
additional recording device to make a simultaneous recording.
Verify the settings of your computer, Windows, the drivers, and SONAR.
Be sure to check that the settings have been made correctly as described in this document. If the settings are
incorrect, recording will not occur correctly. Depending on the performance of your computer, it may be
necessary to adjust the buffer size of the REAC driver. Depending on your computer's hardware, on its
version of Windows, and on the software that is installed, it may be necessary to make other settings in
addition to those described in this document.
Check the free space on the hard disk before recording.
Before you record, make sure that the hard disk has sufficient free space, taking into account relevant factors
such as the recording time, the number of tracks you'll be recording, and the sample rate.
Be sure to format the recording hard disk before you record.
If the hard disk is significantly fragmented, recording may stop because the hard disk cannot provide sufficient
performance.
Do not use other software during recording.
Recording might not occur correctly if you use other software (including Windows Store apps for Windows 8).
Do not place the computer in a hot location.
Depending on the temperature of the location in which the computer is placed, you may need to take
measures to prevent overheating.
