+ .SH SYNOPSIS
+@@ -6,41 +6,72 @@
+ .RI [ options ]
+ .I captureDevice
+ .SH DESCRIPTION
+-\fBtuneit\fP plays Vorbis and MPEG audio files while allowing the user
+-to choose a new tempo without changing the pitch.
++Tune\-It is a very simple command-line based instrument tuner for Linux.
+ .PP
+-The tempo can be interactively controlled by pressing '+' or '-', incrementing
+-and decrementing the playback tempo by 1 percent respectively.
+-Use "q" to stop playback.
++It uses two different algorithms for pitch detection.  By default,
++a simple and fast Schmitt Trigger based algorithm is used to detect
++the fundamental frequency of an instrument.  For better and more reliable
++results, there is an alternative FFT based algorithm which is much more CPU
++intensive.
++.PP
++As audio capture backends, ALSA and JACK are supported.  By default, \fBtuneit\fR
++will try to use the hw:0,0 ALSA device.
++.PP
++\fBtuneit\fR captures audio from an audio device and determines the note
++being played, including the distance in cents from the nearest note in
++standard (well\-tempered) tuning. Example display:
++.PP
++Note E  ( 329.628Hz):  +8 cents ( 331.106Hz)
++.PP
++The example was made by connecting an electric guitar to the sound
++card's mic input and playing the high E string (which was tuned slightly
++sharp). The first Hz value is the standard frequency of the E note, and
++the second is the actual frequency being sampled from the audio device.
++In the example, we need to tune the high E string down slightly. When it
++is correct, \fI+0 cents\fR will be displayed.
++.PP
++To exit, interrupt the program (usually control\-C).
++.PP
++If \fBtuneit\fR's output seems to jump around and never settle on a note,
++try one or more of:
++.PP
++\- Run \fBtuneit\fR with the \fB\-f\fR option.
++.PP
++\- Adjust the volume and/or tone controls of your instrument.
++.PP
++\- If your instrument has more than one pickup (such as an electric
++guitar or bass), try the other pickup.
++.PP
++\- For stringed instruments, try the center harmonic of each string
++(for guitar or bass, this would be the harmonic at the 12th fret).
++.PP
++\- For miked acoustic instruments, try a different microphone, or different
++mic placement.
+ .SH OPTIONS
+-\fByatm\fP accepts the following options:
+-.TP
+-.BR  -b
+-Begin playing at
+-.IR time ,
+-given as an offset from the beginning of the file
+-.RB ( 0:00:00 ).
++\fBtuneit\fR accepts the following options:
+ .TP
+-.BR  -e
+-Stop after
+-.IR duration
+-seconds of audio have been decoded.
++\-f
++Use the more CPU intensive FFT based algorithm. This is highly recommended,
++unless your system is too slow to support it.
+ .TP
+-.BR  -t
+-Specify initial tempo as a floating point value, 1.0 is the default.
++\-i
++List available input ports and exit.
+ .TP
+-.BR  -q
+-Inhibit usual output.
++\-j
++Use JACK as the audio transport system (default is to use ALSA).
+ .TP
+-.B  -v, --verbose
+-Print more information.
++.B \-l \fILATENCY\fR
++Measurement window size in 1/N seconds (default is 10).
+ .TP
