This is cool. But the name is a bit misleading. I have the same 0.25x - 2x speed range on Youtube anyhow. What it adds is the looping capability. So this is rather LoopTube then SlowTube.

By the way: It would be nice if something like this would be available with better sound quality for slow speeds. I am now half way through listening to this at 0.25:

With better sound quality this would be pretty epic ...

I built a similar web thing a while back, except it allowed real-time arbitrary slowing down, and at high quality. The issue was that it was a copyright lawsuit waiting to happen, given that it ripped the audio from youtube. It works well and is all web based, but I'm too scared to release it to beyond just my friends and myself.

The options that won't make lawyers get involved are limited, which is possibly why op did it this way.

Why not just make it into a chrome plugin then?

Because many people don't use chrome.

Imo, not everyone knows they can slow things down on youtube, and "slowtube" transmit the idea they're trying to build much better than "looptube" despite it being slightly inaccurate.

Yeah I was hoping it had some kind of aesthetically advanced interpolation on the audio.

You can loop on YouTube, at least in the browser. Just right click on the player and select "Loop".

You can loop the entire video, not sections of it

In my experience VLC is pretty good at slowing sound down. It can also play videos straight from Youtube.

Trying it now. At 0.3x it also has these weird ripples in the sound as if it just loops very short sequences.

There must be a better way!

There are very specialized filters for extreme stretching, e.g. ‘PaulStretch’ is popular among the ‘800%’ stretch-meme crowd. But it adds a distinct ethereal quality. Audacity seems to have this filter, and might be alright at stretching in general.

Command-line `sox` also does slowing down better than ffmpeg at speeds like 0.7, but dunno about 0.3.

Interesting. Just tried PaulStretch.

While it sounds more "logical" without the strange micro-repeats, it takes all of the punch out of the music.

On youtube, at x0.25 a drum hit goes from KABOUM! to something like:

KAKAKABOBOBOBUMUMUM

While with PaulStretch, it goes to something like:

FFHHAHAHCHCHOHUHMHH

No kick, no pressure behind the lower frequencies anymore.

It sounds like it is far far in the distance.

Sounds about right, that's why PaulStretch is typically used to create otherworldly ‘ambient’ soundscapes.

Something like Brian Eno turned back into proper Eno: https://www.youtube.com/watch?v=BnoX3E2WFcc

The looping feature is a nice addition
