URGENT - Focusrite Scarlett 2i2 "latency" issues -

I am fairly new to the whole recording side of music
I am using a Scarlett Focusrite 2i2.
(I had recorded an overdub for a client who had delivered me a WAV - everything worked fine.)

I have a piece of work I have to deliver tomorrow - a 3 track piece. My problem is I am getting a terrible lag - I guess it is latency.
I have played around with all the settings and but I'm still getting the delay

Any help or advice to get me out this hole asap would be really appreciated

See this page in the manual: https://manual.audacityteam.org/man/latency_test.html

And this tutorial set may be useful too: https://manual.audacityteam.org/man/tut ... rdubs.html

I did the latency test - it seems the click track through my mic was around 20ms BEFORE the generated click track.
Adjusting the latency setting by +2- and -20 ms had no effect

I already performed the latency test - the playback click through my mic was appeared AHEAD of the generated click track??????

If the newly recorded track plays earlier than the original track, then the "Track shift after record" is too much (too negative).

What are your current settings for "Buffer length" and "Track shift after record"?

Machine latency. You should plug your headphones into the Scarlett, not the computer. The computer headphone system is always going to have "one computer late" delay and echo and you can't stop it.

The Audacity latency setting is Recording Latency. That's the one you set to make your new track match the timing of your old ones.

Yup - did all that, and latency is still a massive issue - messed with direct monitor setting on the 2i2.

missed the project deadline, now resorting to timeshifting 4 recorded lines for each of 3 pieces.

This program with the 2i2 has been a nightmare!

How did you set the recording latency? If your latency is far enough off, you can chase your tail for a very long time. I recommend using Generate > Click Track at the default values except maybe slower than normal. Set up for overdubbing and use that as the backing track. Play that into your headphones (plugged into the 2i2) and jam the headphones against the microphone.

The latency correction will be the time difference between the two tracks.

I always get the (+) and (-) correction wrong the first time.
