Recorder Mode

This mode allows you to record one or more input channels to individual mono WAV files.  The analyzer will also display the spectrum of the signal while recording is in progress.  

When using the RAM file access mode, the program will attempt to allocate enough memory  for the recording and will reduce the recording length if not enough memory is available.  The recording length is specified in the File Options dialog box.

When using the Hard Disk file access mode, the program will record directly from your hard disk.  Temporary files are created during hard disk recording.  Use the <File><Set Paths> menu command to specify the directory to be used for these temporary files.  All temporary files are removed when the application closes.  

When a .WAV file is opened, the original sampling rate and format are read from the file.  The current sampling rate is always displayed in the status bar along the bottom of the application for the channel corresponding to the plot which has the "focus" (its title bar is highlighted).

Continuous Recording Capability
Wave files can store up to 2 GB of data in a single file (the corresponding time depends upon the sampling format).  When this limit is reached, the program will momentarily stop recording, save the file and then start recording again in a new file.  If the file is does not yet have a name, the program will give it a name using the computer date and time.  The file will be stored in the \wave folder as specified in the <File><Set Paths> dialog.  This feature applies to the hard disk recording mode only.

Example: c:\spectra\wave\recording_2010_11_26_102011.wav                     
(in this example the date and time were 10:20:11 Nov, 26 2010 when the file was saved)

Important:
During hard disk recording sessions, do not perform other disk intensive operations (such as opening a major application).  Although Windows is a multitasking operating system, it relies on the cooperation of individual applications and cannot guarantee immediate access to system resources.
