I am not sure what you mean by "the screen share" - do you mean /usr/bin/screen? I doubt it has anything to do with SoX stopping. > It stopped after 5 minutes. > minion-2-recording:~ minion$ ~/sox/rec -V5 -c 8 -b 16 -r 48k /Volumes/CAF3/test77.aif > /Users/minion/sox/rec: SoX v14.4.2 > time: Feb 22 2015 14:58:07 You SoX is nine years old. The first thing to try is to use the current version. How did you install your SoX? Is that a pre-built OSX binary? The last published version of that is indeed 14.4.2 Build and install from https://sourceforge.net/p/sox/code/ci/master/tree/ and see if the problem persists. I vaguely remember there were problems in the past with sox finishing prematurely. > uname: Darwin minion-2-recording 22.6.0 Darwin Kernel Version 22.6.0: Wed Jul 5 22:17:35 PDT 2023; root:xnu-8796.141.3~6/RELEASE_ARM64_T8112 x86_64 > compiler: gcc 4.2.1 Compatible Apple LLVM 6.0 (clang-600.0.56) Uff. > /Users/minion/sox/rec DBUG coreaudio: audio device did not accept 2 channels.

This seems stramge too, as you did not tell sox to use two channels, or to use a 44100 sample rate. > /Users/minion/sox/rec WARN formats: can't set 8 channels; using 18 This is understandable. > Input File : 'default' (coreaudio) > Channels : 18 > Sample Rate : 48000 > Precision : 32-bit > Sample Encoding: 32-bit Signed Integer PCM > Endian Type : little > Reverse Nibbles: no > Reverse Bits : no > > /Users/minion/sox/rec DBUG aiff: converted 48000 to 100 16 37777777673 37777777600 0 0 0 0 0 0 Looking at the write_ieee_extended() function is src/aif.c, this seems to be some cleverty of saving an integer, viewed as a double, in a buffer of ten chars and storing that instead, reporting the ten bytes as octals: lsx_debug_more("converted %g to %o %o %o %o %o %o %o %o %o %o", It seems that AIF stores the sample rate in this way. Looking around srcc/aiff.c, there are also "Machine-independent I/O routines for IEEE floating-point numbers", (c) Apple 1991. Apparently, SoX needs a maintainer. > Output File : '/Volumes/CAF3/test77.aif' > Channels : 8 > Sample Rate : 48000 > Precision : 16-bit > Sample Encoding: 16-bit Signed Integer PCM > Endian Type : big > Reverse Nibbles: no > Reverse Bits : no > Comment : 'Processed by SoX' > > /Users/minion/sox/rec DBUG effects: sox_add_effect: extending effects table, new size = 8 > /Users/minion/sox/rec DBUG remix: 0: > /Users/minion/sox/rec DBUG remix: 0 0.333333 > /Users/minion/sox/rec DBUG remix: 8 0.333333 > /Users/minion/sox/rec DBUG remix: 16 0.333333 > /Users/minion/sox/rec DBUG remix: 1: > /Users/minion/sox/rec DBUG remix: 1 0.333333 > /Users/minion/sox/rec DBUG remix: 9 0.333333 > /Users/minion/sox/rec DBUG remix: 17 0.333333 > /Users/minion/sox/rec DBUG remix: 2: > /Users/minion/sox/rec DBUG remix: 2 0.5 > /Users/minion/sox/rec DBUG remix: 10 0.5 > /Users/minion/sox/rec DBUG remix: 3: > /Users/minion/sox/rec DBUG remix: 3 0.5 > /Users/minion/sox/rec DBUG remix: 11 0.5 > /Users/minion/sox/rec DBUG remix: 4: > /Users/minion/sox/rec DBUG remix: 4 0.5 > /Users/minion/sox/rec DBUG remix: 12 0.5 > /Users/minion/sox/rec DBUG remix: 5: > /Users/minion/sox/rec DBUG remix: 5 0.5 > /Users/minion/sox/rec DBUG remix: 13 0.5 > /Users/minion/sox/rec DBUG remix: 6: > /Users/minion/sox/rec DBUG remix: 6 0.5 > /Users/minion/sox/rec DBUG remix: 14 0.5 > /Users/minion/sox/rec DBUG remix: 7: > /Users/minion/sox/rec DBUG remix: 7 0.5 > /Users/minion/sox/rec DBUG remix: 15 0.5 This must be how the 18 input channels contribute to the 8 output channels, in a round-robin fashion, apparently. Which is probably not what you want: 0 to 15 contribute as the two channels into 0-8 each, and then 16 and 17, respectively, are the third contributor to 0 and 1, respectively; the fractions are most probably the relative volumes.

Still no idea why Sox stops here. At any rate, try with the recent version.

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'.
