apower(1) apower(1) NAME apower - Measure signal power of stdin SYNOPSIS apower [-bs blocksize] [-e encoding] [-ccitt] DESCRIPTION apower measures the power of a signal on stdin, printing the power level on stdout every blocksize. arecord(1) | apower is a useful command pipeline. OPTIONS [-bs] Specifies the blocksize. Defaults to 8000 (one second). [-ccitt] Calculates the signal power relative to the official CCITT digital milliwatt. Otherwise calculates the power relative to a sine wave 3.16 dB below digital clipping level. [-e] Specifies the encoding of the data. Valid arguments given by giving a random value to -e. ENVIRONMENT none BUG Probably. If you encounter a reproducible bug, please submit a problem report to (af-bugs@crl.dec.com).
