No. But it's The Girl Who Kicked the Hornet's Nest and the like. It comes in a billion little wavs that get converted to a billion little flacs and them cat'ed into one huge flac (SoX, BTW, has no trouble with a command line with 250+ params). They all have to be cat'ed for the effects to be consistent throughout. > A single instance of SoX will perform the effects in sequence. > You can try running a pipeline of many SoX instances instead: > $ sox input - effect1 | sox - - effect2 | ... | sox - output effectN > Then your operating system could assign each SoX process to a separate CPU.

I'm having no problem at all (well, just a bit at first) with SoX. It's a delightful piece of software. Back in the analog days, I once spent all fall editing and splicing up a project that took all summer to record (Homer's Iliad). Easily a left arm for the likes of SoX/Python back then :-) > I'm not sure you understand: there is no "self sorting". There is if I need to specify the effects in a rational order.

That assumes a little sorting or the command line by me. A mortal. > You still haven't told us what exactly > you want to do with the single input file. I don't know yet. There are a lot of decisions to be made, probably different for every file/user. I want to prepare a sort of menu for the user of various options of some of SoX' effects, then give the list of desired effects to SoX to do, probably overnight. -- Glenn English ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Sox-users mailing list Sox-users@xxxxxxxxxxxxxxxxxxxxx https://lists.sourceforge.net/lists/listinfo/sox-users
