I'm performing some motion capture and audio analyses, and want to collect the data (from the jit.matrix) as a text file for later statistical analyses.

To do this I am using the 'capture' object, however, the enormous amount of data I'm collecting has slowed the computer latency to 1.5 - 2 seconds.

Is their another way (not using coll) to collect the data as a .txt file, that will reduce CPU etc?

Maybe undertake the overall process in two parts?

First: capture and save the matrix data in its native format (.jxf). Second: Load the matrix data and export/render it to a text file after the actual capture as an offline process - then you don't need to worry so much about the time it will take...
