2024-09-21 Firefox user 15843365 Love it! Now I can finally sing karaoke in lower keys!
2024-09-18 zabinga This addon is pretty much as good as it gets when it comes to Speed/Pitch Changers, on ANY browser. This addon absolutely TRASHES on the largest one on Chrome (transpose.video), with the latter having to thank it after. Obviously nothing even remotely compares on Firefox or anything else. Excellent work easily one of the best addons a web browser can have, and a genuine W for Firefox. I strongly agree with the other review on this being very worth porting to Chrome though.
2024-07-08 Kol Heikkinen I'd really love if the creator could make a version of this extension for Chrome.
2024-06-10 ilikebigjuicybooties worked better than i would have thought, very good
2024-04-04 LimoWreck This was exactly what I was looking for, and has served me well for over a year. I can change the speed and pitch independently and easily.
2024-03-12 Pahheb A great Firefox alternative to the Chrome-only https://transpose.video, which does what it says on the box. The pitch-shifting algorithm does produce slight artifacting at certain pitches, but overall works well enough to be able to sing along. *However, keep in mind that for it to work well, the (preserved pitch) option has to be turned off.
2024-03-01 HyperK The key change distorts the audio into an insane mess. The very well hidden "Pitch presevation" does nothing to fix this. The speed shift seems to work on that (lots of artifacts though), pitch preservation works on that. It's doing really interesting things, just not what I'm looking for in a pitch shift extension. Think it needs a rework. Or... reskin and call it The Sataniser? :P
2024-03-01 Firefox user 18309097 Love it! Best add-on to be able to 'Nightcore' your music wherever you listen to it. Small issue, though: Doesn't currently seem to work in Spotify, though. It will change the song for a few seconds before it goes back to normal.
2024-02-27 Codey yes i actually like this speed pitch changer update it works better it does and i did not like the other one i did not you know the old update i did not just the new one i do but one thing though i knowest somebody's gotta fix the high pitched voice because it sounds like when you go upper it sounds like the voice goes back to the original it does at the end when you tune the pitch upper the low pitch sounds fine but the high pitched does not and i knowest once in great while too it keeps loading too sometimes like the youtube videos does and do you guys think you can change the quality to high quality too or no because sometimes it sounds like a robot quality it does can you guys change it to the original quality or no you know the high quality or no
