So I need to record 2 mics on separate audio files using the tascam dr-40x just wondering if this is possible? So we're recording a stage play but I need one mic to the left of the stage and one to the right but all recording the same time.

According to page 29 of the reference manual, this is not possible.

There are two mono modes: INT MONO (which records a mono file using the two internal microphones) or EXT IN 1 (which records the left external input in mono).

All of the other options are stereo, presumably saved to one interleaved stereo file (I don't own this recorder, I simply downloaded the reference manual from Tascam's site). I don't see any way to get two mono files, one for the left input and one for the right input.

Record as normal and then in post split the files into mono files. Pan as needed.

Would Sound Devices Wave Agent help you? You can use this app to break interleaved files into separate wav files.

Free Audacity also does this, with a couple of clicks.

Click the down arrow next to the name of the track, then select "Split Stereo Track":

REC MODE: Stereo
SOURCE: EXT INDEP.

Yes Wave Agent can do this. It’s free and can do this as a batch process. It also has a simple audio file player-where any or all audio tracks contained within a single mono, stereo or polywave file can be played, with L or C or R panning/Mute/Solo and fader for each track within a stereo/polywave. It’s much easier to use than having to open a DAW and split into mono files to check out
which track is which, audition a quickie mix, and is very helpful in guiding the splitting decisions for a polwave.
(eg when I need to split out a quad B-format file plus various stereo and mono files from a single polywave).

What's happened to the OP - not so urgent after all?

Guess he got his information and went on about his day. We deliver answers with a smile, no?
