> both Christof's and Jack's solution still create audio drops.

did you actually tweek the parameter?? there *must* be a setting where you don't get dropouts but the question is rather if this setting is acceptable for you.

Okay, update with all the solutions everyone has chipped in. (THANKS AGAIN)
 
both Christof's and Jack's solution still create audio drops. Now I am testing Jean-Yves's patch and seems to do the trick. 
 
again, thank you all. If anyone has another idea, I will be interested in looking at other solutions (just for the heck of it).
 
ps. Thanks Jack, I will try changing the [block] 
 
cheers

I know why it happens but it doesn't really matter. Despite its flashy read appearance it's just a warning which can be safely ignored.

The patch itself should work. Tweek the amount of samples per DSP block to find a setting which works for you without dropouts.

Thanks, I am opening them up just now. Christof, your patch gives me these errors when I try it out:

soundfiler_read: truncated to 44100 elements -> this one is repeated by the amount of blocks it will take to completely load the sound file
resize failed

any idea why?? (before I start dismantling it?)

Cheers Guys, much appreciated.

    José, I think I have a solution which might work for you. see my
    attached patch. it's not a clean abstraction but rather
    demonstrates the principle.

    basically, I spread the loading of the soundfile over several DSP
    blocks and you can adjust how many samples to load in one block.
    44100 samples, for example, works fine for me (no dropouts), which
    means I can load 1 second of audio in 1.5 ms or 10 minutes in 900 ms!

    note that it needs soundfile_info from iemlib.

    [soundfiler] will vomit at you in the Pd console but you can
    simply ignore it by setting the log level to 0.

    Anyway, I'm really thinking of turning it into an external because
    there some inefficiencies I could get rid off. Most notably, I
    have to use an intermediate buffer plus |read -resize -maxsize
    ...( to prevent [soundfiler] from reading the file always till the
    end because it doesn't have -nframes as an read option (which is
    unfortunate).

    Hope that helps!

    Thank you all..

    but I am developing patches that are handed to performers and

    machines and RAM-DISK settings because I can not tell my
    performers - you need to do all of this and invest in your
    computer first before you play my music. Why? because this is
    something I am doing for my PhD. Yes..saying "buy a fancy computer

    places of the world and that is not my aim. I am trying to squeeze
    the best solutions on any type of machine and to provide people
    that are not necessary computer music users with the friendliest
    setup I can think of.

    the computer I am programming this is a iMac from 2007 with 4 gb
    of RAM. I have many processes including FFT, but thanks to switch~
    I am able to optimize the patch. I just have this problem that
    causes audio drops when loading each sample. So not really wanna

    Actually, the average Windows user will have more 32-bit apps than
    64-bit apps running on their 64-bit OS ;-).
    And most Pd users on 64-bit Windows will have a 32-bit Pd  because
    Miller doesn't offer 64-bit binaries yet and building from source
    is still impossible (at least with MinGW).

    on 32-bit Windows you usually get 2 GB per process - or 3 GB with
    some tricks*. on 64-bit Windows it's 2 GB for 32-bit processes
    unless you compile with IMAGE_FILE_LARGE_ADDRESS_AWARE set, then
    you get 4 GB.

    I actually I didn't know about IMAGE_FILE_LARGE_ADDRESS_AWARE
    until now. Miller could actually use it in his 32-bit Windows
    builds, which currently only allow 2 GB**. It won't do any harm on
    32-bit systems and doubles the available memory on 64-bit systems.

    :-o. time to finally get my dual boot. I weren't so lazy...


    Christof


    * IMAGE_FILE_LARGE_ADDRESS_AWARE set + 4GT enabled (risky)
    ** I tested this with latest vanilla 32-bit binaries on Windows 7
    64-bit (with 16 GB of RAM installed). I get a warning when I try
    to exceed 2 GB.

    In reality, it's even less, usually 2 GB, which is a bit more than
    1,5 hours of stereo audio @44100 Hz. Pd will give you a warning
    when you try to exceed this limit ("pd: resizebytes() failed - out
    of memory").
