That is a bit annoying, yes, but right before the usage test, it should have printed an error message saying what it didn't like about your commandline. > on my ubuntu system, sox failed completely complaining that that it wasn't > set for "auto" .....

Yes, but that was during the wav->raw conversion. The sample rate wasn't stored in the raw file, because raw files are just that: raw audio data, with no headers indicating sampling rate for encoding format. For the play command to be able to handle a raw file, it needs to be told the rate and format when it's run. > play FAIL formats: bad input format for file `myfile.raw': sampling rate was > not specified -- Dan Nelson dnel...@allantgroup.com _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
