High frequencies get cut? about spleeter HOT 8 CLOSED

It looks like all models only output up to 11 kHz. Would be nice to know if this is part of the model or stems from the original training data

from spleeter.

We've just updated the FAQ for making clearer how you can actually perform separation above 11kHz.
Notably we pushed alternate configuration files (spleeter:2stems-16kHz, spleeter:4stems-16kHz and spleeter:5stems-16kHz) that perform separation up to 16kHz and explained how you can set upper separation frequency in the config file if you need another value.

Try using this cmd :: python3 -m spleeter separate -i audio_example.mp3 -o output -p spleeter:2stems-16kHz

Hey Aarni,

Thanks for your feedback. Indeed the default behavior is to cut frequencies above 11Khz but it can be changed in the settings. Read this comment for details.

@mmoussallam but this still means that the models do not predict masks above 11khz, right? is this hardcoded in a training config?

from spleeter.

@faroit, yes, you're right: models are only trained until 11kHz and don't predict anything above.
This is set in the training config through the F parameter (see the wiki).
This is just a design choice that we made, when training the models we provide.

@mmoussallam Thank you for the clarification!

Just a quick follow up,
I've been trying to incorporate the alternate 16kHz configuration using
spleeter separate -i audio_example.mp3 -o audio_output -p spleeter:4stems-16kHz
which raises the following error:
ERROR:spleeter:No embedded configuration 2stems-16kHz found
And
spleeter separate -i my_audio_file.mp3 -c spleeter:4stems-16kHz -o /output/path
which raises the following error:
spleeter separate: error: argument -c/--codec: invalid choice:

I'm currently running a Mac OSX, Python 3.7.3, I also attempted to reinstall spleeter with the same results. Any idea whats going on here?

Thanks,
