A/B player Extension

With this extension, you can loop sections of audio on supported services. This is a really useful tool if you are a musician and want to play along songs you found on your favorite music/video streaming service.

With keyboard shortcuts, it is easy to mark in and out audio. Two markers (A and B) can be placed at current playhead position when you need. You can also change the playback speed down to 0.2x and up to 5x. This is not available for example on YouTube.

Also it is generally not possible to download music from streaming sevices directly to your computer but with the help of web players of these services, it is possible to do music training using the browser.

Currently supported pages;

youtube.com

musi.sh (Apple Music)

vimeo.com

tidal.com

These services will be covered later on upon request;

open.spotify.com

soundcloud.com

HW Park (ID: 000000160e554e54) Voted 5 ★ - Updated 06/21/2022 It's a good program. I am using it for language learning. I just wish I could select the A and B buttons with keyboard shortcuts. Now, I select the beginning and the end of a sentence through several mouse clicks, but it is very inconvenient because this part is repeated over and over again.
