NAME

sbrec − obtain sound data from the audio interface and outputs the data to files

SYNOPSIS

sbrec [ −d device ] [ −i level ] [ −inch channel ] [ −insel input ] [ options ] file

DESCRIPTION

sbrec reads sound data from the audio interface in the format specified by any options and stores the data in a file under a Sony Multimedia data format. 

OPTIONS

−d device
specifies the audio interface being used. If the −d option is not specified, /dev/sbe0 will be opened.  If this fails, the device file /dev/sb0 will be opened. 

−i inputlevel
specifies the input level. This value (∗1) can be from −32.0 dB to 0.0 dB in 0.5 dB increments. If not specified, the previous setting is used.

∗1This value can be from −16.0 dB to +16.0 in 0.5 dB increments on NWS-5000 series.  NWS-3100 series does not support this option.  The value can be from −10.0 dB to +7.5 dB in 2.5 dB increments when line inputfrom the board is used with /dev/sbe0. 

−inch channel
specifies the setting parameter which defines whether the data is input only to the left channel or to both channels when the LINE SELECTOR output is mono data. ∗3

mono Specifies the setting is to both channels. 

stereo Specifies the setting is only to the left channel. 

−insel input
specifies the input select. The following options input are available. ∗2

box Specifies microphone/speaker box as input (for /dev/sbe0.) 

line Specifies the board’s LINE IN (RCA pin jack) as input (for /dev/sbe0.) 

mic Specifies mic as input (for NWS-5000.) 

line Specifies LINE-IN as input (for NWS-5000.) 

cdrom Specifies CD-ROM drive as input (for NWS-5000.) 

da output of this interface as input (for NWS-5000.) 

slot Specifies SLOT as input (for NWS-5000.) 

The following options can be specified when using this command. 

Specifying the Cording
