A long scan leaves hundreds of recordings, each with a JSON sidecar of measurements and, where a recogniser heard speech, a transcript. Reading that meant opening files one at a time and guessing which were worth playing. saunterbrowse is a second executable in the same package. Arrow keys move through the recordings; the transcript of whichever is highlighted fills the top of the screen, because that is the part anyone actually wants to read. Enter plays it, handing the file to whichever player is installed -- the recordings are ordinary WAVs, every desktop already has something that plays them, and a browser that cannot start would be worse than one that cannot play. t opens the whole transcript full screen when it is longer than the panel, and says so rather than cutting the end off silently. / filters on the frequency, the name, the identification, or anything that was said, which is the point of it: "was the repeater mentioned" is a question about content. Sidecars are read only for the rows on screen, so a directory of ten thousand recordings opens instantly. Where there is no transcript the panel says which of the reasons applies -- Morse (decoded, and shown), data, a bare carrier, or speech never offered to a recogniser -- because those want different things done about them. It only ever reads. Two things were only found by driving it through a real terminal. sys.stdin.read(1) goes through a buffered text wrapper, which in cbreak mode waits for more bytes than one keypress provides: the program drew its first frame and then hung, while tests against a stand-in stream object passed. It reads the file descriptor now, and the tests drive a pty. And stopping playback signalled only the direct child, so a player that is a wrapper script kept the sound going with nothing on screen to stop it; the whole process group is signalled instead, which is what start_new_session was there for. man saunterbrowse ships beside man bandsaunter, and the two point at each other.

.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
