Hi I want to stop the audio in all channels {audio.stop ( ) } but one channel , It is posible to leave playing only one channel and stop the rest ?
For example, is this code right:
audio.stop( )—Stop all channels
audio.stop(1)—stop only channel 1
audio.stop(-1) —stop all channels and leave only channel 1 playing ?
if not right how you do it?
Some help please
local function stopAllButOne( keep ) for i = 1, audio.totalChannels do if( i ~= keep ) then audio.stop(i) end end end
Then
stopAllButOne( 5 ) -- stop all known channels but 5Hi @hec2rin,
I see this is a duplicate post (please resist doing so in the future, so we can more easily track issues and help you solve them).
I responded with my suggestion in the post linked below, which is similar to @roaminggamer’s, but I added in a check for “audio.isChannelActive()” so that the audio engine doesn’t attempt to stop a channel which isn’t being used. If you combine my code with @roaminggamer’s function-based code here, you have a winning solution.

I’m going to copy Brent’s answer here and get rid of the other thread.

Hi @hec2rin,
If you know that channel 1 is the only channel you want to keep playing, I suggest just looping through the remaining channels and stopping them:
for c = 2,audio.totalChannels do if ( audio.isChannelActive( c ) ) then audio.stop( c ) end end
Hope this helps,
Brent
Please post any follow ups on this thread.

Very good, Thanks for your help and quick responses! works great!
Hi, my app is base on 2 or more objets everyone has a mp3
local nota1 = audio.loadSound(“M1.mp3”)
local nota2 = audio.loadSound(“M2.mp3”)
–when you began or moved event.phase
local object = display.newImage ( “bStop.png” )
object.x = 200
object.y = 200
object.id = “ball object”
local function stopAllButOne( keep )
for i = 1, audio.totalChannels do
if( i ~= keep ) then
audio.stop(i)
end
end
end
function object:touch( event )
if event.phase == “began” or event.phase == “moved” then
if(event.target == object) then
stopAllButOne( 1 )
audio.play(nota1, {channel=1})
end
elseif event.phase == “ended” or event.phase == “cancelled” then
audio.stop(1)
end
end
object:addEventListener(“touch”, object)
Runtime:addEventListener(“touch”, object)
–and the same for the second object
Everything works fine when i move my finger and touch the objects turns on and off the audio as programed it but,
I need a multi touch activated it and when i do that (system.activate…)
and i touch both objects only one sound…What else do i need to do? any help?
Hi @hec2rin,
Well in that case, it seems that you actually want two audio channels playing, correct? So you can’t stop all channels except the first…
Hi Brent,
Yes you are right 2 or more at the same time its all depends how many objects we touch at the same time at first I thought that will work the same on multitouch, but now make sense to me, absolutely my app is going to have like 20 objects doing the same-thing,
any idea? Thanks for replay
Hi @hec2rin,
Out of curiosity, why is it necessary to stop all other audio channels when you start playing? Normally, I just let the audio engine pick a free channel and play on that channel. Please explain why you need to stop audio before playing new audio. What kind of app is this? What does it basically do?
Of course, if you let the audio engine auto-manage itself, and your app allows more that 32 consecutive sounds, then you’ll have a problem because that’s the limit on available consecutive channels.

Thanks for everything. Just would like to know why I can not use Multitouch with this code.
Everything works fine, just the way I need it. But when I use Multitouch, it gives me problems

I would like to help you more, but multitouch is a very specific process that must be crafted according to your app. Corona provides you with the ability to get a unique “touch ID” for each touch on the screen, along with the ability to set the “focus” of each touch on a particular object. From there, you need to figure out how to handle it in your project, and what should happen on each phase of each touch, along with what happens when a touch loses focus on the object it started on. We (staff) can’t really know what your project is supposed to do and how it’s supposed to behave with multitouch.
I can suggest that you look here for details on setting touch focus:

Best regards,
