I am trying to transpose a sample across several octaves so I have a sample library of, in this case, someone singing "doo".
I recorded a sample in the middle of the range, and bulk transposed this to all the other relevant pitches using the sox pitch command.
However, the results are not very good. In the high register, for instance, listen to the front of the sound: https://adaptiveeartraining.com/magmaGold/js/samples/voice_doo/A5.wav. I can confirm the sample rate is the same as the original file.
(original audio for comparison: https://adaptiveeartraining.com/magmaGold/js/samples/voice_doo/D4.wav)
Using AudioFinder, I got much better results; all the "doos" sound great. However, I was not able to find how I can save each transposed sample to a new file and that's what I need to end up with.
Could someone advise a (free/cheap) workflow for ending up with my sample transposed do the different pitches that sounds decent? As AudioFinder shows, it seems possible without recording multiple samples. So perhaps adding some other commands to sox can help here?
