Make microphone record system audio output - audio

So, yesterday, i was calling with my friend and i wanted to play him an sound from a game, but i had no idea how, because he couldn't hear mine sound. So, is there a way to direct all the system audio to record on the microphone? And also keep the normal output so i can hear it. Thanks for help!
And also, please make your answer noob-friendly, because i am pretty bad with this, thanks!
Other stuff:
I want to direct the output into the microphone, not just the calling program (it's Skype by the way).
Please don't answer that i should put the output to the speakers and record it like it, because i don't even have speakers... just headphones.

Capture voice from a stream and translate it

I hoped that potentially there is something that will help me do it with just one step, however there might be other steps for it.
The problem is, that there is a game I follow, however all the major informations (devblogs and streams) is passed over mostly in french. Today there is one stream on Twitch that I would love to understand, however French has never crossed my path outside of the game. I was hoping there would be a way for me to launch the stream, capture the text spoken during it and translate it to English.
So far, the best idea that came to my mind would be to open up google translate, turn the volume up and let it speak to itself, however I hoped there would be something that listens to an application/window inside the system without the use of the actual microphone and speaker.
Enjoy your day, all!

How to anonymize (mask) audio (human voice) using javascript

I'm hoping to record the audio of some stories from remote study participants via web browsers. I would like to give them an option of anonymizing their voices before they submit their audio clips. Is there a way to do that in Javascript (or any other library--for example, Python--that I can invoke in the background on the server before serving it back to the participant to verify before they submit?
This youtube video comes really close to what I would like to accomplish. Thanks in advance for your suggestions and advice!
You can use the PitchShifter object of SoundTouchJS to change the 'key' of the input, and even the playback rate if necessary. It might be helpful to run further convolvers against the AudioNode as well, to futher anonamize it.

Audio processing steganography on iOS

For one of our projects, we got a new requirement on our hands but I don't have any idea about how to do it.
We need to process audio captured from the environment and do something in the app (show a message, picture, etc) when a specific pattern is recognized.
The first thing that came to my mind when I heard this requirement was Shazam. I did a little research and found Echo Print library (http://echoprint.me). I think that works on the whole of the songs, what I need to do is constantly listen to environment and act when the patterns are recognized. I don't know anything about audio processing (at least for now) but this sounds more like steganography. Correct me if I'm wrong.
Any help will be greatly appreciated!
EDIT: I think I need to correct some points in my question. Yes, the application will listen to the environment but it will recognize the patterns in a pre-configured audio. A specific song on a radio, a dog bark, etc. So the patterns will be artificially defined in the audio.
Thanks.

Sound Effects? Mixer

Ok right I have a voice recorder which records whatever the user plays, says etc
Is there anyway where i can have effects such as 'slow motion voice' or just like changing the sound effects. Or the 'bass' drops or something
So like a Mixer.
Consider looking into BASS for your audio library. You can use it with many languages. It has sample code for some of the functionality you are looking for, and is a good way to get started.

TI-99 speech effect?

I want to make a program that takes recorded speech and transforms it so it sounds like it's coming from a Texas TI-99. Do you have any good ideas and resources for how to go about that?
Most of those old speech synthesizers were build directly in-chip. Perhaps you could find a synthesizer that sounds like the chip, but if you really want the original sound, you would either have to simulate the chip (I don't know if it's a simple matter, perhaps the chip internals aren't published).
I only know because I burnt out a number of the Radio Shack speech synthesizer ICs before I managed to get a SP0256-AL2 working.
If you're more of a do-it yourself type guy, you need to find out which IC actually drove the speech synthesis in a TI-99, and then build the chip up on a bread board. That's what I was trying to do back then, and I managed to get the chip to speak, but lost patience after I fried my third chip due to a mis-wiring issue when I attempted to attach it to my PC's parallel port. I think this was the book I was using back then, but there's no cover art featured so it's hard to know for sure.
If you are familiar with how to use ROM images, there seems to be a gentleman that has managed to refeverse engineer the ROM image out of a SP0256-AL2. Look here for the image and the incredible granted permission to do the work and distribute the results.
You could start with open source that does something similar: Adding Robotic/Vocoder effect to your song using Audacity
