hello everybody !
i found this message on alsa-user today, and it's exactly a problem
i was trying to solve myself:
<rene writes:>
Hi.
I need to play several sounds (wav or mp3) at one time, but I need
to control
the starting of every single sound manually, so a
multitrack-recording is not a
solution (I need this for a play of our laity-theater).
We could use a keyboard and assign the sounds to the keys but we
havn't such a
keyboard. And one of the sounds is about 1 minute - I don't know if
that is
possible with a keyboard.
So I tried to solve this with my PC by playing 2 or 3 sounds at one
time but
this didn't work (can using /dev/dsp only once a time).
Is there a way to do this with alsa and a soundblaster 64 PCI??
Any other soulution?
Thanks in anticipation.
Bye Rene
PS: did anyone know where to find a soundfile of a crying baby?

has anyone used a linux box for theater sound effects ?
i think this might be a very useful thing. it should feature
"instant play", i.e. buffer the beginnings (ok, i know some shithead
has patents on that) and mix an arbitrary number of samples of
arbitrary length. latency is not the key issue here - if it's under
50ms, it's fast enough for cues :)
can the linuxsampler folks comment on this ?
the problem here might be sample length (which might easily be many
minutes, let's say for an atmo).
plus the baby must be staaaaaaable.
looping and other sampler-typical features are nice but not
essential.
does such a program exist yet ?
if not, could you sampler folks maybe include this usage into your
specs ?
there might even be a market for this. i know what i'm talking
about, i've been mixing more than a few theater events, and i've
been doing effects on cue with a pile of audio cassettes... :)
when the software is there, we could cook up a good hardware
suggestion (a laptop with good sound, an external symmetric output
stage) and maybe some day the Linux-Audio-Distro and put up a
website to promote linux as a fx engine and more for theater uses.
regards,
jörn
ps: i'd suggest to cc: answers that might be of use to rene to
alsa-user and keep the rest of the discussion on LAD.
