Проблема задержки (latency) в Pro Tools LE

[Steph]

Известная проблема Pro Tools LE.

Я прикрепил PDF файл (на английском), в котором подробно описано как решить эту проблему c помощью плагина DigiRack Time Adjuster. Можно сразу начать читать со второй страницы, а так же некоторые советы по recording/monitoring latency можно найти на proaudiosupport.com и soundonsound.com

Корректирование задержки плагином DigiRack Time Adjuster:

Once you’ve found out the number of samples
of delay on a track, you can manually
compensate for this delay by using the
DigiRack Time Adjuster plug-in (see figure 2)
on the other tracks in the session to regain the
time alignment between all tracks.
Alternatively, instead of using the Time
Adjuster plug-in on other tracks in Pro Tools to
compensate for latency on a single track, one
can simply move or “nudge” the track in
question backwards the same number of
samples as reported by the track’s Delay view

Корректирование задержки с помощью Grabber Tool:

When you record into Pro Tools there is a latency of 164 samples. All tracks recorded into Pro Tools have 164 samples of latency, but you will not notice this with the first track unless you have a MIDI click, or a recorded click to play along with. Thus, when you record the second track/pass, you will hear latency when the two tracks are played together.

Explains how to deal with this issue.

1) After recording your second track/pass into Pro Tools, adjust the newly recorded audio track to compensate for the 164 samples of latency.
2) Select the second pass of audio with the Grabber Tool. Edit Menu > Shift. Click "Earlier" and type in 164 in the "Samples" field. Click "OK". Now, Pro Tools will locate the audio 164 samples earlier.
3) "Shift" each track or recorded pass back by 164 samples immediately after recording. If you are stacking up tracks, you definitely want them all to be in sync as each new one is recorded.
4) If you recorded your audio at the very start of the session, you will have to trim in the audio before the waveform starts to allow space for the audio to be shifted 164 samples ahead.
