I'm making a podcast player, and I am looking to change the playback rate without changing the pitch.
I know we can accomplish that via an <audio> element, but that's not ideal.
I tried Howler and the web API with little luck. The playback rate changes the pitch, which makes listening experience unbearable.
How can we increase the playback speed without changing the pitch?
Thank you! :)

I’m trying to collect footage from a game. Is it at all possible to have it play at say, twice the speed?
In the sense that if I run it for an hour, I want to capture multiple hours of in-game time.
i dont really know, what you mean but you can record only every second frame, so the video looks twice as fast

I would like to plot the CPU and memory usage of an application on linux vs time. What is the best way to do this?
Would greping these values out from top every 0.1s and writing them into some file work - or is there a better and easier way?
There is an easier way. All of the information displayed in top can be found in /proc/<pid>/, most of it in /proc/<pid>/stat. man proc describes the content of these files.

I want to make a speaker recognition system. I don’t want to make it using deep learning as perhaps it will require a lot of data. Can I implement it using audio components mentioned above or more?
In all case, you will need data learning if you want to "recognize" speakers. A classical approach is based on MFCC computation and a classification by kMeans (or more elaborate GMMs).
You'll find here an overview of the full system of the LIUM for speaker diarization (which is more sophisticated).

What is another way to play sounds in Win RT instead of using Media Element? I'd like to play some "play-and-forget" sounds.
You can have multiple MediaElements or you can use XAudio2 or WASAPI, but multiple MediaElements is possibly the easiest way. Just track which one is done playing so you can reuse it.

Digging around on youtube and flickr's APIs, I noticed Flickr allows you to poll all recent comments (once per hour). Youtube however only allows pulling all comments for a specific video. I'm curious if anyone has any clever ideas on a way to poll+cache or search site-wide youtube comments. I don't know what the comments per second rate is on youtube but I'm guessing it's insane.
