Audio stitcher from pool of labelled recordings. You put WAV recordings with
audacity style labels marking lexical symbols along side with same name as audio
but txt extension. Then do something like the following:
(setf *resources* (mapcar #'audio-resource-from-label-file
(list "./audios/alpha.txt"
"./audios/num.txt"
"./audios/rubbish.txt")))
;; input is the sequence we want to generate
(let ((input (list "b" "b" "1" "d" "c" "2" "2" "4"))
(out "out.wav"))
(uiop:delete-file-if-exists out)
(stitch-plan (find-plan input *resources*) out))On command line, you can do the following:
# json maps output filename to the sequence
# {
# "abc.wav": ["a", "b", "c"],
# "numbers.wav": ["1", "2", "3"]
# }
# audio-dir contains labels and wav files
./roswell/stitch.ros --input-json ./test.json --audio-dir ./audios/ --output-dir ./generated-audios- [ ] Planner handling contiguous segments.
- [ ] Support for positional bias for symbols.
- [ ] Minor WAV reading optimizations.
