I know it should be in the /bin/, but I get a new machine every year and keep forgetting how to move it and get the correct path (~/.bash_profile?) and don’t want to pester our tech staff to do it, so in the command line I just have to type the extra ~/sox/rec. The path can be whatever - as long as it is in your $PATH you can just call 'sox'. You can also specify the PATH at the beginning you your crontab. (This has nothing to do with sox.) > Second, in this example I don’t understand where the file is > being written to. Exactly where the command says: /tmp/file-`date +\%s`.wav Look under /tmp, see the files named file-whatever. > Last, it didn’t create a new file, but just stopped after 1 minute. Yes - it creates a new one at the beginning of the next minute. Jan PS: Please quote the emails you are replying to properly and don't top-post. It is customary in tech mailing list to quote the relevant portion verbatim and comment inline. Also, please wrap your lines - some pople (me included) read this in a text terminal. Long lines make it unnecessarily difficult to quote a bit from one "line" which is in fact a whole paragraph. > > > 5/13/24, 08:47, "Jan Stary" <hans@xxxxxxxx>: > > On May 13 09:26:10, hans@xxxxxxxx wrote: > > On May 12 22:56:45, D.Cottle@xxxxxxxx wrote: > > > If someone needs files from 1:35 to 3:15 we just give them 1 to 4. > > > They combine them (with no seam at 2pm) [...] We routinely combine files > > > into larger segments and we need them to be seamless. > > > > Ah, right, that's what you mean by "sample perfect".
