 .SH DESCRIPTION
 
-dahdi_monitor monitors a DAHDI channel. It gives you a visual
-representation of the sound strengths and makes it easy to see if
-the received or transmitted signals are too high or out of
-balance
+dahdi_monitor monitors a Dahdi channel. It can record the output to a
+file, play it to the speaker, or visualize the audio levels on the
+terminal.
+
+Recorded audio files are by default raw signed linear PCM. If the file
+name ends with ".wav", the recorded file will be a WAV file.
+
+The visual display shows the current audio level at both the Rx
+(audio Received by Asterisk) and
+Tx (audio Transmitted by Asterisk) 
+
+To exit the program, press Ctrl-C.
 
 .SH OPTIONS
 The first (mandatory) parameter is the number of the channel
 to monitor.
 
+.B \-m
+.RS
+Multiple channels. Don't multiplex both Rx and Tx in a single channel.
+Normally there's a different option that you need that implies it.
+.RE
+
+.B \-o
+.RS
+Plays the output to OSS (/dev/dsp). Requires -m not to be used.
+.RE
+
 .B \-v
 .RS
-Display visual audio levels.
+Display Visual audio levels. With two v-s, Verbose mode is enabled, that
+shows the actual levels as numbers. Note that this requires a terminal
+wider than 80 columns to be properly displayed.
+
+Implies -m.
 .RE
 
 .B \-f \fIFILE
 .RS
-Write output to FILE
+Record the content of the channel (Tx + Rx) to a file.
+.RE
+
+.B \-F \fIFILE
+.RS
+Record the content of the channel (Tx + Rx) before the echo canceler
+to a file.
+.RE
+
+.B \-r \fIFILE
+.RS
+Record the content of the Rx channel to a file.
+
+Implies -m.
+.RE
+
+.B \-R \fIFILE
+.RS
+Record the content of the R channel before the echo canceler to a file.
+
+Implies -m.
+.RE
+
+.B \-s \fIFILE
+.RS
+Record the content of the Tx and Rx of the channel to a file.
+.RE
+
+.B \-S \fIFILE
+.RS
+Records a stereo of both Tx and Rx of the channel before the echo
+canceler to a file.
 .RE
 
-Some extra, yet undocumented, options.
+.B \-t \fIFILE
+.RS
+Record the content of the Tx channel to a file.
+
+Implies -m.
+.RE
+
+.B \-T \fIFILE
+.RS
+Record the content of the Tx channel before the echo canceler to a file.
+
+Implies -m.
+.RE
+
+.SH EXAMPLES
+
+Visualize audio levels on DAHDI channel 2:
+
+  dahdi_monitor 2 -v
+
+
+Record channel 3 to a file:
+
+  dahdi_monitor 3 -f output.raw
+
+This will create a raw PCM file (signed-linear, 8kHz, mono, 16 bits per
+sample). Both the Tx and Rx will be multiplexed in a single channel.
+It can be converted to a WAV file using e.g.:
+
+  sox -s -c1 -2 -r8000 output.raw output.wav
+
+
+Record Tx and Rx of channel 5 to separate files. This time directly to
+WAV files:
+
+  dahdi_monitor 5 -r output_rx.wav -t output_tx.wav
+
+
+Record channel 8 to a stereo file (Tx and Rx on its two channels):
+
+  dahdi_monitor 8 -s output.raw
+
+Converting it to a WAV file:
+
+  sox -s -c2 -2 -r8000 output.raw output.wav
+
