20- and 24-bit files use one-and-a-half times the disk space of comparable 16-bit files.
Note: Turning on this parameter only makes sense if you are using a 20- or 24-bit
interface.
• Software Monitoring checkbox: This option allows you to turn Software Monitoring
(listening to the actual input signal) on or off. In most situations, you should leave it
on.
Note: When Software Monitoring is on, the audio signal is processed via software, and
a certain amount of audible delay (commonly referred to as latency) is inevitable.
If you are listening to the recorded signal through your mixing console, or your audio
interface supports hardware monitoring, you should turn this option off.
• Independent Monitoring Level (for Record Enabled Channel Strips) checkbox: Select this
checkbox to allow the use of an independent monitoring level for record-enabled audio
channel strips. After record-enabling a track, you can adjust the fader to the level you
want. The original level will be restored when you turn off the record-enable button.
Note: Adjustments to the fader do not affect the recording level; they only affect the
monitoring level.
• Process Buffer Range pop-up menu: This parameter determines the size of the buffer
used to compute mixes and effects. You can choose between Small, Medium, and Large
buffer sizes.
Note: Larger buffer sizes increase latency. Depending on the speed of the processor,
buffer sizes that are too small might compromise real-time audio processing.
• ReWire Behavior pop-up menu: Use this pop-up menu to configure the ReWire behavior
when sending MIDI data to a ReWire-compatible software instrument:
• Playback mode: Use when playing back MIDI tracks via ReWire. This setting requires
less processing power.
• Live mode: Use when playing a ReWire instrument live. This setting uses more
processing resources, but has lower latency.
• Maximum Scrub Speed pop-up menu: This pop-up menu allows you to set the maximum
scrubbing speed. You can choose between the following options:
• Normal: The normal playback speed is used for scrubbing.
• Double: The scrubbing playback speed is twice as fast.
• Scrub Response pop-up menu: The options in this pop-up menu let you set the reaction
time for audio scrubbing. Choose the value that works best for your system
configuration. Options are Slow, Normal, Fast, and Faster.
