Error: write EPIPE on use of trim effect

[hillct]

Sox seems to be exiting, or at least, the stdin stream is closing prematurely, whenever the following sox Options are used:

var soxOptions={ input: {type: 'mp3' }, output: {type: 'wav'}, effects: ['trim',10] };

Trimming any amount yields the same result. Bumping up the verbosity to -V3 yields no useful data with regard to a failing of the sox command line, but it's unclear whether this is an issue of Node's internal streams handling, something within Duplexer or sox-stream itself. The issue appears 100% reproducible on Linux and Mac though primary testing was done on Mac. Any guidance would be helpful. Thanks.
