Hey! Long time no post here on DEV. I've been dealing with my mental health issue for a while. I was diagnosed with Bipolar-mixed with Depression and Anxiety a while back after a village hacking group played with me(they're still on the run but are currently under surveillance).
Anyway, here's a quick post to check on how to display the tempo of an audio using librosa. You can check the ipython notebook in google colab if you wish to.
I'm using our song We are Monsters. Check it out if you like it.
You can follow the installation process in their documentation or follow this article 😉
Install and import librosa
python -m pip install librosa
import librosa
Upload and load the audio file in the notebook as a waveform in y and store the sample rate as sr
audio_file = librosa.load('We Are Monsters.wav')
y, sr = audio_file
Then load the tempo tracker to get the estimated tempo of the track
tempo, beat_frames = librosa.beat.beat_track(y=y, sr=sr)
print('Estimated tempo: {:.2f} beats per minute'.format(tempo))
Estimated tempo: 161.50 beats per minute
We then convert the beat frames into timings and get the estimated tempo of the track
beat_times = librosa.frames_to_time(beat_frames, sr=sr)
beat_times
Output:

Conclusion
There's a lot you can do with librosa like Feature Exraction, displaying an audio's spectogram, add effects to songs, check the beat and tempo of a song, and many more. Anyway, I'm still learning this library, any advice or challenge on anything about this library can be very helpful. 👍

Hey Vicente! It's awesome seeing a fresh post from ya. Been a long while!
I'm so sorry for all the mess that you've gone through with those hackers. I'll be thinking about you dealing with your diagnosis. I have a history of bipolarism in my family and I know it's really difficult thing to go through.
Anywho, really appreciate ya coming back to post here again and share your learnings with us!
Appreciate this man! It's a whole group that has a program that can read my thoughts, hear my inner voice, have a remote neural monitor and voice2skull on me. I have been researching on how they can read my thoughts and hear my inner voice but couldn't find one.
If I may ask, how'd you deal with the bipolarism in your family?
Apologies if I haven't checked messages on discord yet! Will reply when I feel better!
Wow, that sounds extreme! I really hope that all that stops for ya.
Dealing with bipolarism in my family kinda differed depending on the situation. Both my grandmother, my uncle, and some of my cousins have been diagnosed. I have always just done my best to be kind and understanding to these folks because I know it's gotta be a tough thing to go through. I know they take medications, but I honestly couldn't tell you what they are. My grandmother (mom's mom) passed many years ago in a car crash, and I know she was diagnosed later in life... I was pretty young when she left us, but I know that she was fighting it. I wish I had some good advice for ya, but I am definitely not a professional and only really know the littlest bit from interacting with others.
On another note, don't ya worry about missing any Discord messages. It's great to speak with ya here.
