problems persist, reset to 128 and try a different remedy.
Also, if you are playing a large file, and using maximum latency, a too-small I/O buffer size may
cause dropouts or crashes. Try increasing the buffer size by blocks of 128.
Record Latency Adjustment (samples)
If you loop an audio output back into an audio input, and re-record a track this way, the audio doesn’t
line up. For some sound cards, it is off quite significantly. This record latency adjustment is a
compensation for that delay.
You can do an approximate measurement of the delay by turning on samples as the resolution unit
in the Time Ruler, and comparing the original track with the re-recorded track. Then you can enter a
value in the Manual Offset field to compensate.
If you use ASIO mode, enter 0 in the Manual Offset field and leave the Reported Input Latency
check box checked (this check box only appears in ASIO mode). This will line up audio in most
cases. If you think you can tweak it closer, use the Manual Offset field.
In ASIO mode, the current active ASIO device (remember ASIO can only have one active at a time)
reports its “Input Latency.” You can't edit this value. This supposedly accounts for buffer size, A/D
Conversion latency, etc. The check box allows you to use this reported value. It is checked by
default. In any case, the amount entered into the Manual Offset field will be combined (added to)
the reported value if you have it checked.
