Re: [PD] playing long audio files
Dear List ! I made this patch to play long stereo audio file. You can load audiofile and play, but before - reset the sizes of tables. BUT, it plays only one stereo file in my Vanilla. So when i played one file and try to load another: i push the RESET-bang .. and PD crushes totally.. I can't understand the logic of it at all.. When the same algorithm is done with one table (mono play) - resetting works.. when it is two tables - it crushes. Please somebody look into the patch and try yourself - it is simple and commented inside. What can i do ? Thanks !

Re: [PD] playing long audio files
Hi IOhannes ! Thanks for very particular answer and looking through the patch ! The only puprose with wich i do this complex resizing is that i need to play large audio files. The -resize tag somehow doesn't allow the samples longer then one-two minutes.. That was my initial issue, when starting this thread. The useful answer i found was: http://puredata.hurleur.com/sujet-4301-pausing-resuming-playback-multiple-large-audio-files For those who don't know, you can resize a table with a message like so: [; table_name resize 15876;( I like to set a max-size with a message like this, load a file into the table with [soundfiler], and then send the total samples output of [soundfiler] to another resize message to be sure there isn't any empty space after the loaded file. Later i found the example patch made by the guy (in attach). And it works well. You can reload files of different lenght into it. But it is only for mono. My attempt was to make the same thing for stereo, which is just doubling everything. My system has 6 GB of OM and 4 is available (Win7), but i'm agree that it is not elegant solution to resize tables like that.. anyway in my code they are resized one after another.. so in my logic that should have been working. But it doesn't. Did you try to play long stereo files in PD and reload them ? What can be the way ? thanks !
