oss_digi96 - RME Digi96 professional audio driver.
DESCRIPTION
Audio driver for the RME Digi96 family of profressional audio controllers.
o Only 16 and 24/32 bit audio formats are supported.
o All Digi96 family members support 32kHz, 44.1kHz, 48kHz, 64kHz, 88.2kHz and 96kHz. sampling rates.
MIXER PANEL
Note! For recording you need to set digi96.sync to INTERNAL and the values of digi96.mode and digi96.input to match your studio setup. Oth-
erwise recordings will fail with I/O error.
There are several settings that can be changed using the ossmix program shipped with OSS. Note that some features don't work with all
Digi96 family members. For example ADAT mode is not supported by the base model.
o digi96.mode <SPDIF|AESEBU|ADAT>: This setting controls the output mode which can be S/PDIF (consumer), AES/EBU (professional) or ADAT.
The input mode is detected automatically. If ADAT input is detected the output mode will be switched to ADAT automatically (this
doesn't work in the other direction).
o digi96.sync <EXTERNAL|INTERNAL>: This setting tells if the playback sampling rate is based on the internal oscillator or the sample rate
detected in the input port. See also the definition of the digi96.worldclk setting.
o digi96.input <OPTICAL|COAXIAL|INTERNAL|XLR>: Selects the active input.
o digi96.sel <BYPASS|NORMAL>: When set to BYPASS the input signal will be routed directly to the output (also sets digi96.sync automati-
cally to EXTERNAL). In this mode audio data written to /dev/dsp will be muted.
o digi96.worldclk ON|OFF: Setting this control to ON will enable the optional worldclock input as the sample rate source (overrides the
digi96.sync setting).
o digi96.emph ON|OFF: Enables/disables the de-emphasis option on the analog (monitor) output connector.
o digi96.data <AUDIO|AC3>: Specifies if the output signal is audio or AC3 data (sets the non-audio bit in the channel status data).

/dev/volume
DESCRIPTION
The audio device serves a one-level directory, giving access to the stereo audio ports. Audio is the data file, which can be read or writ-
ten to use the port. Audio data is a sequence of stereo samples, left sample first. Each sample is a 16 bit little-endian two's comple-
ment integer; the default sampling rate is 44.1 kHz. Some implementations only support audio output and return a zero length when read.
Volume is the control file associated with the audio port. Each input and output source has an associated stereo volume control, ranging
from 0 (quiet) to 100 (loud). In addition, there are controls for the sampling rate of the D/A and A/D converters and for any tone con-
trols. Reads return lines of the form
source in left value right value out left value right value
possibly abbreviated if the values are shared or non-existent. For example, if all of the values are shared, the form degenerates to
`source value'. Valid sources depend on the particular audio device, though all devices have a audio stereo source, which controls the
output volume from the D/A converter connected to audio.
Writes accept the same format with same abbreviations. Writing the string reset sets all of the attributes to their default value, and if
no attribute is supplied, audio is assumed.
The Sound Blaster 16 (or MCD) is half-duplex and has the following controls.
audio out
Data written to audio.
synth in out
MIDI synthesizer.
cd in out
CD player.
line in out
Line-level input.
mic in out
Monaural microphone input.
speaker in out
Monaural internal speaker connection.
treb out
Stereo treble tone control. Values less than 50 decrease the treble, those greater increase it.
bass out
Stereo bass tone control.
speed in out
Sampling rate for the D/A and A/D converters, expressed in Hz. Defaults to 44100.
Indigo audio is full-duplex and has the following controls.
audio out
Data written to audio.
line in out
Line-level input.
mic in out
Microphone input.
aes in out
Digital input.
Nextstation audio is output only and has the following controls.
audio Data written to audio.
deemp A value of zero turns off the stereo de-emphasis filter, any other value turns it on.
