I've heard so many people say: "Python can't do...", "Python shouldn't really do...", and "Python isn't..." Throughout all my learning up to this point I'm seeing now that Python can do just about anything and I don't understand this half-aversion to Python a lot of developers seem to have when talking about anything that isn't reading tables and manipulating data. Thanks for making this - everyone I had talked to about this topic kept pointing me back to learning C++ and I thought that was a lame answer.

[@robmulla]

Love this feedback. Glad to hear this helps you start your python journey. It’s such an awesome language. The others are good too!

[@twinblade02]

So the reason why devs say things like this is because Python is rarely used to actually put out a full fledged application that's essentially IOT compatible; then there's the speed. C++ is apparently faster so everyone wants you to learn that.

[@milesmann03]

C++ is a lot more safe to use than python IF you know how to allocate the memory, but it’s a risk if you don’t. Relating to this video, as someone who goes to a C++-focused comp sci department, I’ve never been taught how to audio process in C++ but it may be possible

[@pywidem5823]

Working in both audio and IT, this sample rate display in your files feel like they're halved. To be able to display a frequency accurate, you'd need 2xfrequency as the sample rate, therefore it would be 44.1khz (which is much more common and I have never seen the option to record witch 22050hz). With 22050 you would have data representing only up to roughly 10khz when accounting for the inquest filter.

[@joefagan9335]

22050 is used all over the place where full CD quality (44100) isn’t required. For speech 8000Hz is the max needed and 22050 can sample as you pointed out up to 11KHz

[@nixboaski]

This is so interesting. A few days ago I wanted to produce a digital reproduction of a particular musical note, using the note as the basis and its harmonics (I was analysing A=440Hz, but I wrote the script in such a way I could alter that). So I had basically two aspects to take into account: the frequencies and its amplitudes. I recorded a note from the piano, cleaned it of noise as much as I could and extracted the amplitudes from it for each frequency that forms an A note. It was terrible! The final result sounded ghastly. Your video will help me understand how I must proceed to make a digital sound that makes more sense. I totally would like to learn how to use machine learning on audio processing too.

[@robmulla]

Great question. In this part of the video I am just zooming into part of the audio to show how it looks visually in the plot. Each datapoint has a relatioship to time by the "sample rate" - this audio file has a sample rate of 22050 Hz (22050 samples / second). so 1 sample is 1/ 22050 of a second. This slice of 500 samples equates to ~0.0227 seconds. Hope that helps!

[@robmulla]

Great question OrangUtan - the y-axis values in that plot is in decibels (dB). Decibels are not an absolute measure of sound energy but a comparison with a reference value. In the librosa function "power_to_db" you can see it takes a reference value, which we provide as the max value. Since dBs are in log scale all negative numbers are less than this max value. Hope that helps! Check this out for more info: www.scienceabc.com/pure-sciences/why-negative-decibels-are-a-thing.html

Hello! Thank you for the excellent video! I have a question though: What is the difference in use cases between STFT and Melspectrogram? Both methods appear to extract features for the model, but in distinct ways. I am interested in understanding when one is more advantageous than the other. For example for sentiment analysis, I think melspec seems more appropriate but it's nothing more than a guess with a bit of intuion, and feels like if we feel with a speech its better to use melspec and any other sound stft

[@space_aware7846]

Awesome video! Is there a way to use the Melspectrogram to determine programmatically if a file contains human speech?

[@robmulla]

Thanks. That’s a great question. It would depend on how accurate you would need the system to be and the volume of the voice. You could setup a heuristic to determine if there is voice based on the frequencies. You could also train a machine learning model as a classification problem. This would require a lot of labeled examples. There also may be some pre-trained models you could use.

[@bradydyson65]

Why does it seem like the frequency values in the spectrograms are much higher than they should be?

Hey, thanks for the comment. This sounds like an interesting project. I'd be a bit concerned with using something like this for such a serious medical condition like sleep apnea.

if you want to increase the resolution on the x axis you can increase the sr. But how do you increase the resolution of the frequency on the y axis? Edit: It seems quite hard to use this code to shift the frequencies as the frequencies are coded in the iteration of the db matrix ... that was my actual aim because it seemed other software kind of compressed alot of data which mostly seems to be accounted to the mel or log scale... i think. If you want to simple shift 1000 hz to 100 hz you lose a lot of frequencies, which could be compensated with higher y-resolution... but i guess there are more clever methods?

I want to mimick others voice with my voice. In short i will give a small audio sample as a input (for example my voice) and the code will get the various charateristics of my voice so that i can manipulate it with audio of some other person's voice. Is it possible to do it in python?

[@sporttyt]

You can create me product?
