Even though 2× speed followed by 0.5× brings timing back to normal, the audio has already been resampled and interpolated twice, introducing quantisation error, phase distortion, and lossy compression artefacts. Because these transformations aren’t perfectly reversible, the signal degrades and sounds warped even at the original speed.

When you double the speed of the video you’re basically deleting half of the frames in your video, and when you try to slow it back down, you can’t just add those frames back in, instead, you show each frame for more time (double), which effects how you’re video looks and sounds

normal should be 1x not .05x??? unless i’m insane???

You lost data when you sped it up

If you just leave it at 1x speed, it will sound normal like how you want it to sound. Hope that helps 😁

It’s called aliasing. it’s a phenomenon known from digital signal processing. Basically when you 2x the video, you throw away half of the audio samples, when you now do 0.5x you need to stretch the audio samples that are left, this creates a overlap that sounds like a second voice. Hope that helps

The .5x speed did sound back to normal to me

It’s called compression, when you put 2x you throw away 1 frame out of 2.

To go 2x speed you have to remove half of the “frames” of audio. Then slowing it back down, you’re still missing that audio you already removed, which makes it sound different

moazrofl :
speeding a video up/slowing it down works by removing/adding frames to it. when you sped your video up it removed half your frames and when you played it again the original frames werent there thats why its sounds so choppy/doubled

Because the audio is compressed and changed so it’s inherently a different audio to the original. Like how if you increase a number by 10%, then decrease that number by 10% it isn’t the same as the original

Speeding something up tosses half the data (because you only need half as much to fill the time, think about it). But then slowing it back down, you can't just get the data back, so it's kinda gotta guess to make it sound even halfway decent. It's trying to make something from nothing.

Imagine it like this. You build a Lego car, someone takes it apart and tries to build it really fast, they would probably miss out on a couple things or add things somewhere. It’s like that if you think about it. When you speed up the video and slow it down, the computer needs to try rebuild the original voice and can add things or miss out on a couple things.

Imagine taking every other pixel out of an image, cutting the images length in half. Then you stretch the image back to its original length. You don’t now have the same image because there was data lost when you cut the length in half

Same reason if you take a photo, compress it, and then try to make it full res again

i think because putting it in 2x is cuts out some frames to speed it up, then in 0.5 to expand it out there is less content so it plays each frame for twice the time. and doing this to the audio will have the same effect. maybe?

omri rehav :
I think its because of how the speeding up and slowing down works, cuz I tiktok for example when you put it in 2x it modifies the sound so it wont get pitched up, and I assume that is causing problems

Label Me Not :
1x to 2x to 0.5x is the same speed but you’ve distorted the video so much that it’s essentially missing a portion of the audio that it originally had.
