Pre-Record Bar Following is further explanation of the use of the pre-record bar in addition to what is already documented: This bar represents the internal buffering between the media and the HD-P2's audio engine. As the buffer fills up, the bar is filled in from left to right. While recording (or in pre-record) this bar shows how much data, if any, is waiting to be written to the media. Typically the bar will be at or near empty as incoming audio is continually written to the media. It is possible to know when the media is having a hard time keeping up if this bar continues to fill up over time and never goes down. Eventually the buffer fills up and recording is stopped with a buffer overrun warning. During playback the bar represents audio read from the media and queued for playback. Depending on the sample rate, the HD-P2 fills 1/4 to 1/2 of the buffer. If the buffer becomes empty this can be a good indication that the media is having a hard time keeping up with the audio rate. Should the buffer become empty, playback is stopped and a buffer underrun warning is shown. Max File Size This setting, under the Project Settings menu, allows the user to determine the maximum file size of a take (an individual audio file). The range of this setting is 512MB - 2GB and the default setting is 1.5GB. There may be times when smaller audio files are desired to exist within one project. For example, when individual takes may need to be burned to CD media as data. As always, the record/playback of audio file (take) transitions is seamless regardless of the setting of this menu. Auto Markers In addition to dropping markers on audio overs and timecode dropouts, the HD-P2 can drop markers in time increments from 1 minute to 5 minutes. Settings for all three Auto Markers modes are under the Auto Markers menu under the Project menu. No Fault Recording The HD-P2 transparently closes & re-opens audio files every 1.5 seconds while recording. This ensures data safety in the event of power loss or other unpredictable occurrence during recording.

Pre-Record Bar
Following is further explanation of the use of the pre-record bar in addition to what is
already documented:
This bar represents the internal buffering between the media and the HD-P2's audio
engine.
As the buffer fills up, the bar is filled in from left to right.
While recording (or in pre-record) this bar shows how much data, if any, is waiting to be
written to the media.
Typically the bar will be at or near empty as incoming audio is
continually written to the media.
It is possible to know when the media is having a hard
time keeping up if this bar continues to fill up over time and never goes down.
Eventually the buffer fills up and recording is stopped with a buffer overrun warning.
During playback the bar represents audio read from the media and queued for playback.
Depending on the sample rate, the HD-P2 fills 1/4 to 1/2 of the buffer.
If the buffer
becomes empty this can be a good indication that the media is having a hard time keeping
up with the audio rate.
Should the buffer become empty, playback is stopped and a
buffer underrun warning is shown.
Max File Size
This setting, under the Project Settings menu, allows the user to determine the maximum
file size of a take (an individual audio file).
The range of this setting is 512MB – 2GB
and the default setting is 1.5GB.
There may be times when smaller audio files are desired to exist within one project.
For
example, when individual takes may need to be burned to CD media as data.
As always, the record/playback of audio file (take) transitions is seamless regardless of
the setting of this menu.
Auto Markers
In addition to dropping markers on audio overs and timecode dropouts, the HD-P2 can
drop markers in time increments from 1 minute to 5 minutes.
Settings for all three Auto
Markers modes are under the
Auto Markers
menu under the
Project
menu.
No Fault Recording
The HD-P2 transparently closes & re-opens audio files every 1.5 seconds while
recording.
This ensures data safety in the event of power loss or other unpredictable
occurrence during recording.
