NAME
Audio - audio tools available through HP VUE (OBSOLETED)
DESCRIPTION
This manpage describes the audio tools available through HP VUE for playing, recording, and editing
sound. These include Audio Setup, Audio Security, Audio Editor, Audio Control Panel, Audio File and
Data Formats, and Audio Library. Audio(5) also provides information on using other audio tools from the
HP-UX command line.
Audio Setup Requirements
To use the audio tools, you need access to both audio client and server software. This software is part of
HP-UX. The server requires a workstation or X station with Audio hardware.
Audio hardware is built into all Series 700 computers except the 720, 730, and 750; you can upgrade these
models to become the 725, 735, or 755, which do have audio hardware. Note, older 705s (that is, 705s
with the 8MB HP-UX) do not include audio software.
To use audio on an X station, you need either an HP ENVIZEX or ENTRIA X station that includes an
audio accessory kit.
In most cases, you use the audio client and server software on one system. However, if you need the
audio server running on a remote workstation or X station, see aserver (1M). The audio data files can
reside on either system or a third system.
Audio Security
Audio is secured to allow access only to the user on the local workstation. If you need to allow remote sys-
tems to access audio on a workstation, see asecure (1M).
The Audio Editor
The Audio Editor is an OSF/Motif-based tool with play, record, and edit functions. The Editor displays a
waveform that makes it easy to edit and play audio segments.
You can open an audio file, play it, look at its waveform, and use the waveform controls to edit the file.
To set an output device, use the Audio Control Panel.
To record audio, first connect a microphone or other audio equipment that your system supports; perhaps
a CD or tape player. To make the connections, see the Audio Editor online help ("Audio Editor Tasks" sec-
tion) or your system owner’s manual.
You can use the Editor to create and record an audio file.
To start the Editor from the General Toolbox, open the Media Toolbox and drop an audio file on the
Audio Editor control or double-click the control.
To start the Editor in a terminal window, type the following:
/opt/audio/bin/audio_editor
[pathname]
Online help is available through the
Help menu in the upper-right hand corner of the Editor.
The Audio Control Panel
The Audio Control Panel is an OSF/Motif-based tool that you use to set the audio volume and choose the
audio device for playback.
The volume control affects the play volume for any client system of this workstation or X station. The
Audio Control Panel also includes a Stop button to stop the current play operation.
You can also use the Audio Control Panel to choose the device for playback, (headphones, built-in
speaker, or device connected to Line Out, such as external speakers). This choice controls where audio is
played when you double-click an audio file or use the Audio Editor to play a file. The default output dev-
ice is the internal (built-in) speaker.
To start the Audio Control Panel from HP VUE, click on the Audio control in HP VUE Front Panel.
To start the Audio Control Panel in a terminal window, type the following:
/opt/audio/bin/AudioCP
If your system has Audio applications that were developed using an earlier version of Audio software,
those applications may use the SPEAKER environment variable to determine their output devices. You
can set the SPEAKER variable for all applications started by HP VUE by modifying the
