Playing several sounds together or one after another

[chikitin]

Hi,

Assume we have three sound define in a node as follows;

local sound1= sound '.../sound1.ogg"
local sound2= sound '.../sound2.ogg"
local sound3= sound '.../sound3.ogg"


1. How is that possible to play all the sounds: sound1, sound2, and sound 3 together?

sound {sound1,sound2,sound3}.


sound1:play()
sound2:play()
sound3:play()


Is this code right?

2. How can I play one sound after another, like a play list? should we use the pipmak schedule to trigger say sound2 after sound 1 is played? and if so, how do you define the interval for the pipmak.schedule? do we do trial and error or there is a way to calculate accuratly when pipmak must tringer sound 2!!!

I tried to give the exact length ( in miliseconds) in the interval schedule, but it plays sound2 very early and it overlaps with sound1.

Any hlep would be grealty appreciated.

Yes, that should work. It might not be accurate enough if you require
the sounds to overlap exactly, but I'd expect the differences to be on
the order of microseconds.

Yes, exactly. Unfortunately, this is not accurate enough for seamless
concatenation of the sounds - you'll have an unpredictable gap of
several milliseconds. Seamless concatenation is just not possible at the
moment.

In the current development version of Pipmak, sounds have a duration()
method that you can use for that purpose. In Pipmak 0.2.7, your only
option is determining the duration of your sounds beforehand and
hardcoding it in your script.

pipmak.schedule() takes seconds, not milliseconds.
