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:

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

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?
