Basic Sound Processing in Python | SciPy 2015 | Allen Downey

[@mohamedhamza456]

_"I want to make one minor quibble about the idea that there's Mathematics behind anything, there is no math behind anything math is one of the languages that we use to describe the world, computational languages are also languages that we use to describe the world"_ . _Allen Downey_ This is the best thing I've heard in my scientific life. Thank you Mr. Downey.

[@pernu6477]

Unless we live in a simulation, then math IS behind everything.

[@shilohjuelz2478]

instablaster...

[@Yongbangxiang88]

it's not just the technical aspects of the talk, but rather the motivation behind why Allen is doing it (first 1min of talk) and his enthusiasm that impressed me. we need more teachers like him

[@Yongbangxiang88]

fantastic ! passionate presenter + interactive coding + clear explanation.. !

[@MarkJay]

Nice talk. The violin example with convolution reverb was really cool

[@lucaserburu7373]

Thanks Allen for all your contribution for people who are interested and really enjoy working with DSP and Python

[@Digiphex]

This guy is making the leap to Fourier much easier with his work.

[@frab88]

the LTI convolution example was mesmerising.

[@AvantGrade]

[@SuperLucasGuns]

had watched this video a while back, now after taking a systems and signals course I actually understand the violin & gun example. omg this is beautiful

[@NiVofHiR]

You are a GODSEND sir! Thank you for sharing your book and code!

[@user-pw5do6tu7i]

You could probably use that room acoustic transfer in video games quiet effectively. having the same set of base sounds, and then layering on the environment would be a pretty nice system that wouldn't require too much work

[@zetaconvex1987]

Allen Downey always has the most fascinating material.

[@Thekingslayer-ig5se]

Python is a really powerful language

[@laurencelstewart]

If you change the interval of the red alert signal and make a second one with e^-t frequency dependence, and then splice them together, you'll get the Siren sound from Kill Bill.

[@scipyconferencescientificp7936]

Like this talk? See more like it at the SciPy 2016 Conference, to be held July 11-17, 2016 in Austin, Texas. More details at the conference website: scipy2016.scipy.org.

[@JamesTJoseph]

8:57 a black magic using the impulse response of a system.

[@kirankotari]

Awesome, I enjoyed it. I was not getting the basics of DSP before, this is good.

[@jonathannavarrete3744]

Signal processing is time series analysis in the statistical world

[@yaredkassaLegesse]

you are doing a great work keep it up.

[@luxfero9272]

Excellent work sir. Amazing.

[@chaitanyapatil3058]

Amazing! Allen Downey you are a rock star!

[@durgaganesh423]

Hi sir you done awesome job.i have question is it possible find glitch or noise from wav file?

[@kirkwilson6206]

We are implementing the Mamuni project in Kenya and eventually in India and other countries enabling unsophisticated users to make a local phone call on an inexpensive mobile phone and speak any of the indigenous languages of Kenya and listen to Mamuni guide them through steps to enable messaging and a variety of additional Internet-like applications. We need to be able to process single-word user input and compare it to a small number of words recorded by a native speaker of the indigenous language in which the user is speaking. Would you or someone you know be interested in helping us address this issue? Looking forward to hearing from you.

[@markpx]

I had a prof at UC Berkeley who said that everything in the world could be expressed by a Fourier series.

[@TurkishLoserInc]

Not only is it a possibility, but it is a inevitability. Analyzing a continuous environment using discrete particles rather than a continuum is a silly constrain due to lack of ingenuity in fluids education. In the next 10-15 years we will be transitioning from using finitebody simulations to fft based simulations which will both be less computationally expensive, along with being more accurate.

[@bilboswaggins7629]

This is awesome!! Thanks for this knowledge!

[@alexeykokh8240]

Where I could read open Audio processing journals?

[@priyanshipal9077]

brilliant way of explaining things.

[@KendallFrimodig]

i reallly enjoyed this but think you could have increased the volume of the questions being asked, ironic given the topic

[@michaelnimmer222]

Awesome stuff thanks!

[@sandymlgenai]

Given a flute music file, how can we convert the music to notes and decompress the file back to audio blocks using literally any method( trained spectograms, any ML algorithm..)

[@xiaoming7503]

Why there's a Squirt label ?

[@TheRandomDayz1]

you must be a creative person who always looks the out-of-the-box stuff. Here it is literally. :)

[@SuperRichson]

I was looking if anyone else noticed!lol..

[@RichardvanBemmelen]

Wonderful! Science IS fun!

[@daromc01]

how can you install thinkdsp ?

[@AvantGrade]

use sound booster for windows 10 to amplify the sound coming out because the audio in this video is kinda low.

[@kendrakvnhvn10]

Where can I find the notes that he is going over?

[@prasadsonar7316]

I love you enthougt , for valuable content

[@henrifischer1119]

in 2015 they unfortunately were not able to record the questions, only the answers.

[@atharvaathalye]

Sir any tutorials on MFCC creation

[@richtigungod6275]

"Wah! This is 'clever'!"

[@richtigungod6275]

anybody who knows what I'm referring to is invited to join my secret club

[@richtigungod6275]

{1 person will realize it in n time, 2 persons will realize it in (n+n/2) time, 3 persons will realize it in (n+n/2+n/3) time... By the end of KZbin, we are all mathematical retards}

[@AvantGrade]

the "What's up with the noises" video he referred to went from basics to wth is going on I can't understand a single word XD

[@aidangomez9852]

ironic that audio is so poor

[@malekbika9471]

How Can l installation thinkx package in python3

[@maskedredstonerproz]

pip install thinkx??

[@finfamous2546]

7:00 I don't think that A would sound flat, it's insanely close to the point where I think you'd get away with it.

[@mrmkkryt6485]

what were the questions asked by students?

[@milahu]

audio too silent .... sounds like the uploader failed in audio processing : P the magic word is "audio normalization" .... and "dynamic range compression"

[@seeking9145]

Horrible idea to make the screen fancy perspective instead of straight. Makes it hard not to get headache

[@qzorn4440]

Supercalifragilisticexpialidocious, I would like to set this up on the Raspberry pi 2. Thanks. 8*) .

[@annaoaulinovna]

is python programs working as c and c++ ? i think its not

[@secularph8424]

The architecture is different, But the python interpreter is made of C only

[@srinithmadapathi7093]

how do i read .au files throu this module?

[@shando_tube]

Can anyone here recommend the thinkdsp python module for 3D audio?

[@TK390]

I see 9gag. i upvote.

[@amarrajghimire1065]

saw_wave.make_spectrogram(seg_length=512 slice indices must be integers or None or have an __index__ method what is the problem plz suggest me

[@jamesberesford7310]

Did you manage to find a fix? I get the same problem

[@FPS-wv9dk]

subscribed

[@thulitha]

This is the link for the video he referred here . kzbin.info/www/bejne/n5CTdYuug8qUh5I

[@socratesfernandez7667]

This is just as useless as showing colourful CFD results to stakeholders. It's some fancy stuff but absolutely zero fundamentals, playing audios is not teaching.

[@MohakNarang07]

Sounds like a sine wave... lol

[@msadekmarwa5934]

Can you send me the code please!!

[@506jeff]

can't hear shit, audio is way too low for my crap speakers

[@506jeff]

nvm i can hear it fine on my phone

[@alexanderevans8524]

God that's boring. 1 of 2 videos to show this. No idea what I really need.

[@SF-dy6hn]

Show your code
