NetAudio also includes a program which can be used to interpret the side infor-
mation transferred from the RD1x5T, such as the real time, channel conguration,
input levels, and the voice memo channel. This program,
teacin
, is described in
detail in Appendix G. Atypical use of this program is to separate the data stream
from the RD1x5T into three parts: actual data, the voice memo, and the time co de
and control info. If the command:
narecord | teacin -o test
is run, then the data is stored in les named
test.d01
,
test.d02
,
:::
, with the side
information stripp ed, the voice annotation is stored in
test.s01
,
test.s02
,
:::
and
the time code and other side information is stored in
test.ctl
. A new data and
speech le are started each time a break in the timeco de is detected. Thus, once
the ab ove command is started it can be left running while dierent tap es or passages
are played on the RD1x5T. Each new passage will be stored in a separate le.
The
test.ctl
le will contain a single line eachtimeachange in side information or
a discontinuity in the time co de is detected. Atypical output is shown below, with
the line numbers at the left added for reference:

In this example the TEACwas playing a recorded tap e when the host program was
begun. Line 1 indicates that
teacin
locked onto the signal at byte number69of
its input and started storing data in
test.d01
(and the speech trackin
test.s01
)
The tap e was recorded at 13:12:29 on 94/02/03. Recording was done in 4 channel
mode with normal speed (1x). All 4 input channels were set for 2V maximum. For
the next 11 seconds a line was output each time the seconds were advanced in the
