NAME

sbset − set parameters to the audio interface

SYNOPSIS

sbset [ −d device ] [ −i inputlevel ] [ −o outputlevel ] [ −set mode ] [ −inch channel ] [ −insel input ] [ −outsel output ] [ options ]

DESCRIPTION

sbset sets parameters about input level, output level,  cording, sampling frequency, number of channels, number of data bits, monitor function, input select to the audio interface. 

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. 

−o outputlevel
specifies the output level. This value (∗2) can be from −32.0 dB to 0.0 dB in 0.5 dB increments. If not specified, the previous setting is used.

∗2This value can be from −8.0 dB to +8.0 dB in 2.0 dB increments on NWS-3100 series.  The value 0.0 dB is always used when line output from the board is used with /dev/sbe0. 

−set mode
specifies whether the setting is onto input, output or both. The following options mode are available. ∗3

in Specifies the setting is onto input. 

out Specifies the setting is onto output. 

inout Specifies the setting is onto both input and output. 

−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. ∗4
 

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,) or LINE-IN as input (for NWS-5000.) 

mic Specifies mic 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.) 

−outsel output
specifies the output select. The following options output are available. ∗3
 

sp Specifies built-in speaker as output. 

kb Specifies keyboard speaker as output. 

The following options are available for [ options ].

−16 Specifies 16 as the number of data bits. 

Specifying the Sampling Frequency

−8000 Specifies the sampling frequency of 8000 Hz. 

−16000 Specifies the sampling frequency of 16000 Hz. ∗3 ∗5

−32000 Specifies the sampling frequency of 32000 Hz. ∗3 ∗5

−9450 Specifies the sampling frequency of 9450 Hz. ∗5

−18900 Specifies the sampling frequency of 18900 Hz. ∗5

−37800 Specifies the sampling frequency of 37800 Hz. ∗5

−11025 Specifies the sampling frequency of 11025 Hz. ∗3 ∗5

−22050 Specifies the sampling frequency of 22050 Hz. ∗3 ∗5

−44100 Specifies the sampling frequency of 44100 Hz. ∗3 ∗5

−12000 Specifies the sampling frequency of 12000 Hz. ∗3 ∗5

−24000 Specifies the sampling frequency of 24000 Hz. ∗3 ∗5

−48000 Specifies the sampling frequency of 48000 Hz. ∗3 ∗5

−44056 Specifies the sampling frequency of 44056 Hz. ∗3 ∗5

Specifying the File Format for ADPCM ∗5

−sony Specifies the Sony format. 

−cdrom Specifies CD-ROM mode 2, user data format. 

Specifying the Emphasis for ADPCM ∗5

+emphasis Specifies emphasis is on. 

−emphasis Specifies emphasis is off. 

Specifying the Mute Function
