Operation 3
When the Play button is clicked, the yellow cursor begins moving across
the waveform display, while a red cursor marks the original starting point.
Clicking the Stop button once will halt playback at its current position,
while clicking Stop a second time will move it back to the starting point. The
starting point is changed whenever the cursor is forcibly moved, either by
clicking within the waveform window, using the up/down controls on the
time display or dragging the ruler bar.
Playback can also be started and stopped by pressing the spacebar on the
keyboard. Each press toggles between Play and Stop.
If the playback starting point is within the most recent minute recorded,
playback is disabled until such time as it will be safe to start playing without
running into the end of the log. The danger zone is shown with a darker
green on the waveform display, and moving into this zone while playing
will cause playback to pause until such time as it’s safe to resume. A similar
mechanism operates at the beginning of the log to prevent playback of
audio that’s about to be overwritten.
The slider control below the transport buttons sets the playback volume.
This affects only the audio level from Flashback and doesn’t interfere with
other applications or change the sound card mixer settings.
When playing from a Flashlog 7 or Flashlog 8 fitted with DAB capture, the
transmitted DLS text information is displayed in the box at the bottom left
of the window, while transmitted images appear in the box at the bottom
right. Where multiple image types are broadcast, the image type can be
selected using the radio buttons below the calendar panel. Both the DLS
text and image display are cleared whenever the playback starting point is
moved, and won’t update until the next complete text frame or image is
played.
For internet streams, the static metadata from the stream’s header is
displayed in the slideshow box, with Title and Artist metadata, if present,
being shown in the DLS box.
Live monitoring of DAB services from Flashback is now supported, but be
aware that this will consume network resources while running. Clicking on
the “Live” button toggles live playback on and off.
When a DAB service is selected, leaving the mouse pointer hovering on that
channel button for more than five seconds will display a tool tip balloon
showing the full service name, service identifier (SId), sub-channel number
(SubChId), audio sampling rate and type of encoding, the stream bit-rate
and the PAD bit-rate.
