.SH NAME
saunterbrowse \- read and listen to what a bandsaunter scan collected
.SH SYNOPSIS
.B saunterbrowse
.RI [ DIRECTORY ]
.RB [ \-\-sort
.IR ORDER ]
.RB [ \-\-filter
.IR TEXT ]
.RB [ \-\-player
.IR CMD ]
.RB [ \-\-list ]
.SH DESCRIPTION
A scan leaves a directory of recordings. Beside each one is a JSON file
holding what the classifier made of it, and for speech a transcript of what
was said. Reading that by hand means opening files one at a time and guessing
which are worth playing.
.PP
.B saunterbrowse
shows them as a list you move through with the arrow keys. The transcript of
whichever recording is highlighted fills the top of the screen, because that
is the part you actually want to read; underneath it are the identification,
the bands the frequency falls in, and the list itself. Pressing Enter plays
the recording.
.PP
With no
.I DIRECTORY
it opens the one the scanner writes to, taken from your saved settings, so it
normally needs no arguments at all.
.PP
It only ever reads. Nothing in the recordings directory is renamed, moved or
deleted.
.SH KEYS
.TP
.B "Up Down k j"
Move through the recordings.
.TP
.B "PgUp PgDn"
A screenful at a time.
.TP
.B "Home End"
The first and the last.
.TP
.B Enter
Play the highlighted recording. Playing a second one stops the first: two
players talking over each other is worse than either alone.
.TP
.B Space
Stop playing. With nothing playing, it starts, like Enter.
.TP
.B t
Read the whole transcript full screen, scrolling with the arrow keys. Useful
for a long net, where the panel at the top can only show the first few lines
\[em] it says so when there is more.
.TP
.B /
Filter. What you type is matched against the frequency, the filename, the
identification and
.I everything that was said,
so "was the repeater mentioned" is a question you can ask directly. Enter
accepts, Escape clears.
.TP
.B s
Cycle the order: time, frequency, duration.
.TP
.B r
Re-read the directory. A scan running in another window is still writing to
it, and this picks up what has arrived since.
.TP
.B o
Print the highlighted recording's path and quit, for piping into something
else.
.TP
.B "? h"
The list of keys, and which audio player was found.
.TP
.B q
Quit. With a filter in force, Escape clears the filter first.
.SH OPTIONS
.TP
.BI DIRECTORY
Where the recordings are. Defaults to the scanner's output directory, or to
.B $BANDSAUNTER_OUTPUT
when that is set.
.TP
.BI \-\-sort " ORDER"
Start in this order: time, frequency, duration. Time is newest first; duration is longest
first.
.TP
.BI \-\-filter " TEXT"
Start with only the recordings matching this, exactly as if it had been typed
at the
.B /
prompt.
.TP
.BI \-\-player " CMD"
The command used to play a recording. The path is appended as its last
argument. By default the first of these that is installed is used:
pw-play, paplay, aplay, play, ffplay, mpv.
.TP
.B \-\-list
Print one line per recording and exit, without drawing anything. This is what
to use over a pipe, in a script, or anywhere there is no terminal.
.TP
.B \-V ", " \-\-version
Print the version and exit.
.SH SOUND
Playback is handed to whichever player is installed rather than done in the
program: the recordings are ordinary WAV files, every desktop already has
something that plays them, and a browser that cannot start is worse than one
that cannot play. If none is found, everything else still works and the
message says which packages would fix it.
.PP
Over ssh there is usually no sound server at the far end. The browser and its
transcripts work regardless; only Enter has nothing to do.
.SH TRANSCRIPTS
A transcript appears only where a recogniser produced one, which means the
capture was judged to be speech and
.B bandsaunter\-transcribe
was installed at the time. Where there is none, the panel says which of the
several reasons applies \[em] Morse, data, a bare carrier, or speech that was
never offered to a recogniser \[em] because those want different things done
about them.
.PP
Two places can hold the text: the JSON sidecar records what was recognised
during the scan, and the
.I _transcription.txt
beside the recording is what a later re\-run wrote. The file wins, being the
more recent of the two.
.SH FILES
.TP
.I ~/bandsaunter/
Where recordings are written, unless the saved settings say otherwise.
.TP
.IR frequency \-\- date _ time \- modulation .wav
A recording.
.TP
.IR ... .json
Its measurements and identification.
.TP
.IR ... _transcription.txt
What was said, where a recogniser heard speech.
.SH ENVIRONMENT
.TP
.B BANDSAUNTER_OUTPUT
The directory to open, overriding the saved settings.
