resample_annots not implemented yet #237

Closed Hywel-Stoakes closed 3 years ago

Hywel-Stoakes commented 3 years ago

When running the function emuR::resample_annots() there is a warning message:

not implemented yet!!!

Is there a relatively simple way to change the sample rate within annotations in an emuDB? The database I am working on currently, has annotations at 22050 Hz and audio files at 44100 Hz. Thanks

My solution was to resample the audio files back to 22050 Hz and then export to TextGrid usingemuR::export_TextGridCollection(). I was then able to upsample the audio files to 44100 Hz and reconvert to an Emu database using emuR::convert_TextGridCollection. In the process the hierarchy had to be regenerated, but otherwise there was no data loss. The reason for upsampling, is so that the database can be viewed in a Safari-based browser (macOS, iOS) all phonetic analysis is performed on the original database.

I am currently working on the next release of emuR and will either not export that function (no idea why I did it originally) or implement something like an external sox call to perform the audio resampling. So just watch the release notes/change log of the upcoming CRAN release.
