How do you pause and resume a sound?

VideogamerMale

Is it possible to pause a sound file and then resume it where it ended like a YouTube video?

Imagine something like this:

play sound [((MY MP3 FILE HERE) + (the specific second I want it to play at)) v] until done

Not possible. Best you can do is split the sound into smaller bits to get more control.

Okay then. Does the pitch block cheat by speeding up the sound instead of actually pitching it up? Then I could create a system that fast fowards to where you previously left off.

change (pitch v) effect by (10)

I don't use sound much so can't answer that but suspect it would take a bit of managing.

With that there will be a chance to skip sounds. I haven't tried doing it, but I think you need to calculate a lot. :)

I just tested this:

set [pitch v] effect to (-999999999) :: sounds

This almost works, but the song would still be playing, just veeeerrry ssslooooowwly.

You could try this suggestion someone made a few months ago?

I haven’t tried it myself, so would be interested in seeing if it works..

Please create your own topic.

Just create a button and set volume to 0 when it is clicked on.

THANKS!!!

Yes, it is possible, however, it may take some time for it to “load” (eg wait for the sound to reach the desired second)

define Play Sound [sound] starting from second [start second]
set volume to (0) %
set [pitch v] effect to (360)
play sound (sound)
wait ((start second)/(8)) secs
set [pitch v] effect to (0)
set volume to (100) %

Why set the pitch to 360? The maximum pitch effect is 360. Any higher values set it to 360 anyway.
Why wait (start second/8) seconds? When the pitch effect is set to 360, the sound is played eight times as fast. For this reason, the program should wait an eighth of the time it starts.

If you have any questions feel free to ask me! I've followed this topic so I'll get notified if anyone does.

For pausing a sound:

define pause
set volume to (0)%
set [pitch v] effect to ((-1) / (0))  :: sound // sets pitch to -Infinity

For resuming a sound:

define resume
set volume to (100)%
set [pitch v] effect to (0) :: sound

It's not perfect, but still useful.

Can't see how that guarantess the sound restarting at the right place - it'll be completely random, won't it?

That is true. I used this method, and pause a song, then I wait for 7 seconds, but then the song wasn't in the same place as when I paused it.

I believe my method works better

Excellent, Boomer001. Your trick for pausing a sound and unpausing it, works pretty well.
Genious idea to use -Infinity.
Setting volume to 0 or 100, is not even necessary.

Actually, you don't need to do -9999999999. you can do this:

set pitch effect to ( ([ log] of (leave this space blank)))
