@an-npt17 Which options did you use to build with waf? (You can share the complete waf log is located in `build/config.log`). You can check with `ldd /usr/local/lib/python3.8/dist-packages/essentia/_essentia.cpython-38-x86_64-linux-gnu.so` to see missing...

Yes, this is in the wishlist. We can use ffmpeg-3.4.8 which is in Ubuntu 18.04 LTS. We should be careful though as our build scripts for ffmpeg can break due...

Cannot reproduce this error in my local build from source, the file loads fine. Therefore, this error is related to the FFMpeg dependencies in Python wheels. We'll update the way...

Not stale.

Not stale.

+1 on that!

any updates on this? looking forward to use this functionality

Hi @flckv. Do you have specific analysis task in mind? Algorithms such as LPC, MFCC compute features commonly used in speech analysis. Also [pitch detection algorthims](https://essentia.upf.edu/algorithms_reference.html#pitch) can be relevant.

For onsets detection, Essentia provides various detection methods that might be useful: https://essentia.upf.edu/tutorial_rhythm_onsetdetection.html https://essentia.upf.edu/reference/std_OnsetDetection.html https://essentia.upf.edu/reference/std_OnsetDetectionGlobal.html https://essentia.upf.edu/reference/std_SuperFluxExtractor.html

This happens we you a trying to normalize a descriptors which value is always constant across dataset. I've improved the error message in the last commit. Make sure the "cleaner"...
