NAME

decsound − utility for recording and playback of audio messages. 
 
 

SYNOPSIS

decsound [-file filespec] [-play filespec] [-file -] [-play -] [-file - -play] [-play - -file] [-device number] [-help]
 
 

DESCRIPTION

DECsound is a software application that you can use to record and play audio messages. DECsound functions are similar to those of a tape recorder -- you can play, record, fast-forward, and rewind recordings. You can also edit your recordings using the on-screen waveform display. 

With DECsound, you record messages using a microphone that you connect to your workstation. You can use any other source connected to the selected port of your audio device. Audio port selection can be accomplished using Audio Control. You can play back messages on your workstation’s built-in speaker or on headphones connected to your workstation. You can also use a headset that combines a microphone and headphones. 
 
 
 

You can perform basic editing tasks on your recordings. For example, you can use cut-and-paste operations on a DECsound recording in the same way as you would use them on a piece of text. DECsound also provides a library of sound effects that you can use separately or with your own recordings. 
 
 

OPTIONS

DECsound accepts the following command line options:

−file filespec
Specifies the file name to use for the DECsound session.  If the file exists, the DECsound window displays the recording. If the file does not exist, DECsound creates a new recording. DECsound uses Sun AU as the default file type.
 
 

−play filespec
Plays the specified file without displaying the DECsound window.
 
 

−file - Outputs a recording to UNIX stdout.  Data written to stdout is in mono 8kHz mulaw raw audio format only.  When you make a recording and choose Save from either the main screen or the File menu, the recording is written to stdout in raw audio format. There are some restrictions on functions that can be performed when DECsound is run in this mode, and the corresponding buttons and menu entries will be dimmed. 

−play - Plays audio data from UNIX stdin without bringing up the user interface.  Data read from stdin must be in mono 8kHz mulaw raw audio format only.  For example, if an .aud-formatted file is read from stdin, the file header will be played as data, causing additional noise when data is played as audio. 

−file - -play, -play - -file
Brings up the DECsound user interface, and loads audio data from UNIX stdin (instead of from a file). This audio data can then be played back, edited, or written to a file as usual. Data read from stdin must be in mono 8kHz mulaw raw audio format only. For example, if an .aud-formatted file is read from stdin, the file header will be played as data, causing additional noise when data is played as audio. There are some restrictions on the functions that can be performed when DECsound is run in this mode.

−device number
Specifies the number of the audio device on your system to be used for playback and recording. Use audiodevices to determine the audio device numbers.

−help Displays help information.
