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

[@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

[@frab88]

the LTI convolution example was mesmerising.

[@Digiphex]

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

[@NiVofHiR]

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

[@kirankotari]

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

[@bilboswaggins7629]

This is awesome!! Thanks for this knowledge!

[@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

[@luxfero9272]

Excellent work sir. Amazing.

[@yaredkassaLegesse]

you are doing a great work keep it up.

[@chaitanyapatil3058]

Amazing! Allen Downey you are a rock star!

[@zetaconvex1987]

Allen Downey always has the most fascinating material.

[@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.

[@INeedAttentionEXE]

I had no idea that this had such a big impact on my life. Simply amazing. I am a “musician” (a terrible one) that uses impulse responses to simulate reverbs and vintage guitar cabinets. Really engaging concept. :)

[@RichardvanBemmelen]

Wonderful! Science IS fun!

[@michaelnimmer222]

Awesome stuff thanks!

[@alexeykokh8240]

Where I could read open Audio processing journals?

[@jonathannavarrete3744]

Signal processing is time series analysis in the statistical world

[@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.

[@durgaganesh423]

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

[@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..)

[@Thekingslayer-ig5se]

Python is a really powerful language

[@priyanshipal9077]

brilliant way of explaining things.

[@JamesTJoseph]

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

[@kendrakvnhvn10]

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

[@prasadsonar7316]

I love you enthougt , for valuable content

[@daromc01]

how can you install thinkdsp ?

[@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.

[@richtigungod6275]

"Wah! This is 'clever'!"

[@richtigungod6275]

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

[@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..

[@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.

[@KendallFrimodig]

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

[@atharvaathalye]

Sir any tutorials on MFCC creation

[@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

[@mrmkkryt6485]

what were the questions asked by students?

[@AvantGrade]

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

[@qzorn4440]

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

[@malekbika9471]

How Can l installation thinkx package in python3

[@maskedredstonerproz]

pip install thinkx??

[@henrifischer1119]

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

[@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?

[@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]

[@shando_tube]

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

[@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.

[@msadekmarwa5934]

Can you send me the code please!!

[@MohakNarang07]

Sounds like a sine wave... lol

[@aidangomez9852]

ironic that audio is so poor

[@kellydeanbishopatgmaildotc9774]

I have a patent for sound recognition that matches a prerecorded audio template of either vocalized sounds or speech with a live audio template. If the live audio sounds like the prerecorded audio template then there is notification. Speech recognition, such as "Alexa" or "Siri" are manufactured by established companies such as Google or Apple, but the sound recognition technology is still in it's infancy and there aren't many sound recognition manufactures. I'm looking for a manufacturing company that will purchase part or all of my patent. If anyone has any suggestions as to how to find such manufacturing companies with the capability to manufacture the device as a Bluetooth device, device as a cellular a host, GPS capability, and sound recognition manufacturing capability. Please let me know if there are any manufacturing companies that might be interested. Thank you.

[@milahu]

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

[@SF-dy6hn]

Show your code

[@thulitha]

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

[@cking9145]

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

[@506jeff]

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

[@506jeff]

nvm i can hear it fine on my phone

[@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.

[@alexanderevans8524]

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