neither will it preserve pitch information I
noticed. :-( Ok.... if I were to carry on with sox, what syntax would I need to use so that all the 61 files in a folder are matched up with the corresponding ones to output files with the same name in a different folder? The files are called by notes on a scale preceded by a number eg 036-C.wav, 037-C#.wav, 038-D.wav, and so on. I therefore need to match the 036-C.wav in the left folder with the 036-C.wav in the right folder. Mark On 09/12/2016 18:48, Erich Eckner

Hi, I just had a brief look at your example files and it looks like the mono files are actually stereo, but with one channel muted (in retrospect I think, you mentioned that). So the correct sox comman to combine these would be sox -M left.wav right.wav stereo.wav remix 1 4 this imports all 4 channels (actual left channel, silent right channel in left file, silent left channel in right file, actual right channel) to sox and exports only the actual left and right in one file (a.k.a. stereo). However, this will still not preserve the markers. regards, Erich On 09.12.2016 15:10, Dr. Mark Bugeja MD wrote:The mega links works - just tried it myself.

The release marker is placed in the point where the note is released in the actual recorded sample and where the sounds starts to fade away. The software needs to know that moment especially if there are multiple releases available for that note that would represent "staccato", "portato" and longer held notes. This exercise renders more realism when recorded samples are played from a "sampleset" loaded in software like jOrgan, GrandOrgue and Hauptwerk.This would be a perfect beginning of your original post. Now I understand why you need to preserve them: you are building and actual sample library to be used with MIDI. Indeed, attack and sustain and release and decay are indisposable.Picture (42kB): https://mega.nz/#!dQIwkDKI!QlrmlYHywFqpG9ujJfJLBm_1skxaYz88AJJJy4Euxs0An error occurred while loading MEGA.

We apologize for the inconvenienceIn the example demonstated there is no release marker as the "tail" of the waveform was removed and saved as a separate file. So the end of a loops would be the release marker in such instances. Clearly from this picture loops and markers were not retained in the merger using sox though the exercise was purely a simple exercise without any frills of extra codes.
