Re: merging mono files

    I have already alluded to the audio software
        I use, in previous posts. However there is one other I have not
        mentioned.

    I create markers using iZotope RX3
            Advanced. It allows me also to clean up samples from
        noise, cut pieces out, and do all sort of editing, like
        eliminating artefacts, change frequency of a good sample to say
        create missing/ unplayable or discordant notes when sampling a
        real instrument like an old pipe organ. 

    Loops are then generated. I use LoopAuditioneer
        (https://sourceforge.net/projects/loopauditioneer/) created by
        Lars Palo, a small but marvellous piece of software. It also
        sports other features eg generating pitch information to wav
        files vital when selecting to play the virtual instrument set to
        a different temperament to that which it was created from.

    Some software if used may not show
      the loops/ markers and if I recall may even ignore and delete them
      upon saving any changes. I think, but I may be wrong, Audacity
      would do that but Sony Soundforge doesn't. I stand
      to be corrected. I don't use Audacity that much.
    Just for those who are interested, I have a website about my
      project in creating digital samplesets of instruments from
      recorded samples of real instruments: 

      http://maltesepipeorgans.webs.com

    One may listen to these virtual instruments, as they are played
      by remote musicians in their homes, in my other website: 

      http://maltesepipeorgans2.webs.com

    I cannot add more than this since I am in no way technically minded
    to be able to answer certain questions. I am capable of using some
    pieces of software in so far as what I have been taught to do by
    others in the know and, like a monkey, I just copy the steps I was
    shown to accomplish specific, routine and repetitive tasks in the
    process of creating digital wav files. Some processes are carried
    out by others eg noise reduction which can prove quite challenging
    at times considering that recording are made in churches where
    chairs are dragged across, doors banged, people talk in the
    background, cars, buses, trucks and motor bikes zooming past and
    hooting their horn in the busy streets outside, church bells ringing
    half way through a session, birds chirping, etc etc etc. Most
    frustrating. But the end results of hundreds or even thousands of
    hours of hard work are the clear and crisp wav files that can do
    justice to the instrument being replicated digitally.

    The task I am now performing is basically reversing part of the
    process that was done to these files after loops and markers were
    created.... that of recombining the L and R channels back into
    single stereo samples preserving the processing done before the
    separation. Loops and markers are created in positions that apply to
    both channels in a stereo file so they are bound to match exactly
    when recombining them again.

They are created using audio software.

      Well, what software?

        Apologies for any inconvenience caused.

      I'm sure no-one thinks you've caused any inconvenience.  We're all here
because we want to process audio files, and like the approach that sox
offers.

In my case, I use sox for things because it's easy to keep notes 
describing
what sox command I used to do something or other, whereas documenting 
how I
may have used a GUI-based application is far more difficult.  And, I 
worked
as a computer programmer so have little difficulty using sox (& other 
tools)
to find things out about portions of a set of audio files, and then use 
my
own programs to generate sox commands to manipulate those files.

        At least I got as far as
merging two files using a bat process. Re-creating loops and markers
and checking each is as much of a task as the process at hand so might
as well just get on with it.

      Does the audio tool within which you created these markers offer any 
options
for exporting marker definitions separate from audio data?
