Chapter 6: Recording 69
To play back a recorded track:
1 Disable recording on the track by clicking the Record button for the track again. The
button should no longer be highlighted.
2 Click Play in the Transport window or press the Spacebar to play the track.
3 Click Stop in the Transport window or press the Spacebar to stop playback.
Monitoring Latency and Recording
Because Pro Tools LE uses the host processor in your computer for audio processing,
playback, and recording, there is a small amount of audio delay, or latency, when
monitoring audio through the system. You can set the latency shorter when you are
recording and monitoring through Digi 001, and longer when you are trying to achieve
higher track counts with more plug-ins.
Set latency in the Hardware Setup dialog box. Latency is controlled by the Hardware Buffer
Size setting, and is displayed in samples. The recommended setting for listening back to
audio is 512–1024 samples. For recording, when monitoring through Digi 001, the
recommended setting is 128–256 samples.
▲ If have a SampleCell II Plus card, a buffer size of 128 should not be used when
running the SampleCell Editor at the same time as Pro Tools LE. Use a larger
buffer setting to avoid performance errors.
