I am new to linux and want to use it as my daily driver however, I want noise cancellation for my mic and after some googling, I found out that you can edit the pulseaudio config file to load the specific module for it as shown in this :-

https://wiki.archlinux.org/index.php/PulseAudio/Troubleshooting#Enable_Echo/Noise-Cancellation

So I opened terminal, typed

sudo nano /etc/pulse/default.pa 

 ### Enable Echo/Noise-Cancellation load-module module-echo-cancel use_master_format=1 aec_method=webrtc aec_args="analog_gain_control=0 digital_gain_control=1" source_name=echoCancel_source sink_name=echoCancel_sink set-default-source echoCancel_source set-default-sink echoCancel_sink 

after that, I rebooted my computer but everytime I did something related to voice recording made my computer freeze for about a second (like going to Settings->Sound, starting a voice recording in Counter Strike Global Offensive, testing microphone in steam etc…).

Then I opened pavucontrol and saw this :-

Does anyone have a clue as to what I am doing wrong?

## Local Cancellation in Real Hardy Space

I want to show the following asymtotic estimate in Hardy space over $$\mathbb{R}^n$$: Let $$a\in \mathbb{R}$$. I want to show the function $$f(x)=\mathbb{1}_{B(0,1)}-\mathbb{1}_{B(a,1)}$$ is asymtotic to $$\ln|a|$$; that is, $$||f||_{\mathcal{H}^1}\sim \ln|a|$$ The definitions we use here is the following: If $$\varphi\in C_c^\infty(B(0,1))$$, then there is a maximal operator $$M_\varphi(f)(x)=\sup_t |\varphi_t*f| = \sup \frac{1}{t^n}\int_{\mathbb{R}^n}\varphi\left(\frac{x-y}{t}\right) f(y)dy$$ where $$\varphi_t:=\varphi(x/t)/t^n$$ and $$\varphi$$ satisfies $$\int_{B(0,1)}\varphi = 1, \varphi\geq 0,\mbox{ and }\varphi = 1/\mathcal{L}(B(0,1))\;\forall x\in B(0,1/2)$$ The Hardy norm of $$f$$ is defined to be the $$L^1$$-norm of this maximal operator evaluated at $$f$$.

It can be shown that $$||f||_{\mathcal{H}^1}/\ln|a|$$ is certainly bounded by showing $$M_\varphi(f)(x)\geq c|x|^{-n}$$, however the upper bound is the difficulty.

## Can not obtain proof of ticket cancellation from Wizz Air

I have cancelled my tickets for a Wizz Air flight. The refund is not the issue as “cancellation fees were higher than ticker price” and all that, but I need to have a cancellation confirmation in order to get some of that money via a travel insurance that I had made.

The thing is, I have received no such confirmation and a call center rep said that it “might arrive” in a week- – that has also passed, and none arrived.

What else could I do to obtain said cancellation confirmation ?

## Will my F1 visa cancellation affect my application for a B1 visa?

In the past, my F1 visa was canceled upon arrival by the US Department of Homeland Security. They had stated”Insufficient Funds” in the cancellation description, failing to give the bank statements on arrival. Now I have to apply for a B1 visa as part of company travel. Does my F1 visa cancellation affect this B1 application?

## Noise cancelling headphones you can turn the noise cancellation on/off in

I’m not sure if this question is really applicable for this stack so apologies in advance, I’m not sure where else to put it.

I am looking for a pair of overhead earphones that are noise cancelling but have the ability to have the noise cancellation turned on or off. The person I am getting them for travels a lot so it would be handy to have the noise cancellation while on a plane or bus, but they also spend a lot of their time in busy city environments so it would be handy to be able to turn the noise cancelling off too so they are more aware of their surroundings. Thanks in advance and apologies again if this is the wrong place for this question, if anyone knows a better/proper place for it please let me know and I’ll move it there!
