Subject[Csnd] live diskin2 dropouts
I'm using csound live to trigger samples and having dropouts quite often. Usually some seconds after the file started. The samples are 44.1kHz/16Bit and I'm running csound with these flags: -odac3 -iadc4  -d -A -m0 -b256 -B1024 -R

Is there something one can do to avoid the dropouts? Probably it would be better to use a table so that the files are previously loaded in the RAM.

I would be interested in hearing what are your experineces with live samples.

Thanks in advance,

luis

Hi Mr. Luis,
i'm not expert but in my system (and i'm on windows) i need to well set the
size of buffer (-b and -B), and on windows often -B is 4096 at least.
But You can also use gen 1 to load a sample and then read it via loscil (or
other opcodes that read table like poscil). In this latter case (poscil et
sim) there is only to make attention to set right frequency dependent if the
sample is mono or stereo. But there are other way like flooper and flooper2
that allow loop  on sample.

mini help,
ciao,
fran.

Hi Luis -

as francibal said, I'd try to increase the buffer size first. And the  
ksmps?!? I'd try:
ksmps = 128
-b 1024
-B 4096

And diskin2 has an optional ibufsize argument.

But in my experience, playing sounds from the hard disk (regardless  
whether Csound or Max or pd) in a live situation is often a kind of  
vabanque. So if the files are not too large, playing by a buffer might  
be the best. If you like, you can try Useful -> SF play from buffer 2  
in the QuteCsound examples menu.

Ciao -

I fully agree, playing from RAM (buffer, table) is much safer in a
performance situation. Unless you use a RAM disk of course ;-)

Talking about playing from table,
I was looking for a way to play a soundfile with optional skiptime today,
and could only figure out how to do it if I used diskin or soundin.
Anyone know a way to do it when playing from a table ?
(assuming we want support for non-power-of-two table size, otherwise I
could do lphasor+table).

Subject[Csnd] Re: Re: live diskin2 dropouts
If you do insist to read from disk then I think it's better if the  
sound files are read from a separate partition (or external HD) that  
is smallish in size, and NOT the partition on which the OS is  
installed. In addition to other things this ensures that the sound- 
file data doesn't get too fragmented: the fragmentation is kept within  
the small space of the disk partition and so the header doesn't need  
to jump around too much to read the sound-file from disk. Some correct  
me if I'm wrong!

Yes, poscil works. But only for mono files, though.
But your tip got me looking once more, and I found loscilx (somewhat
undocumented) to do the trick.
Thanks ;-)

The reason why I do not want to read from disk during live performance
is not relly related to latency or dropouts,
it's just that reading from disk is a physical operation, and that's
just one more thing that can go wrong. It will seldom actually go
wrong, but it just might.
It happened once to me, maybe 10 years ago, I was reading (with
diskin) a track from a sturdy SCSI disk used only for audio, midway
thru the very last chorus of an uptempo song played as an encore, it
hiccuped and created a short stuttering loop (that happened to be
quite close to 16ths in the current song tempo, luckily...). We sort
of got thru the ending of the song, and I spent the better part of the
day after recovering the disk with Norton.

ah, yes, flooper2 would also work for mono samples.
I was actually browsing the manual earlier today and looked at
flooper/flooper2, but I did not read thoroughly enough to notice the
optional parameters for flooper2. The flooper crossfading loops are
very useful.
