Exporting Files

This feature allows you to export a .WAV file to a variety of file formats.  These files can then be used with a spreadsheet, mathematical processing program, or you custom application.

Destination File Formats:
  • ASCII Integer - File is readable with any text editor.   For mono files, each line contains a single sample value.  For stereo files, each line contains both the left and right sample values separated by a comma.  
  • ASCII Float - File is readable with any text editor but the values are converted to floating point format (e.g. 21.034).   For mono files, each line contains a single sample value.  For stereo files, each line contains both the left and right sample values separated by a comma.
  • Binary 8 bit - 8 bit integer values.
  • Binary 16 bit - 16 bit integer values.
  • Binary 32 bit - 32 bit integer values.
  • Binary floating point - 32 bit floating point values.
  • Universal File Format - type 58 ascii
  • Universal File Format - type 58 binary

    Output Sample Values:
  • 8 bit WAV data:  0...255
  • 16 bit WAV data: -32767...+32767
  • 24 bit WAV data: -8388607...+8388607

    Notes:
  • When exporting stereo files, the channels are interleaved starting with the left channel.  
  • Binary files are much more efficient than text files; ASCII text format is not recommended for large files. 
  • If you wish to export a small time segment from within a large .WAV file, use the time series plot to specify the selected segment and then use the <Edit> <Copy> menu item to place the segment on the clipboard.  Next, close the file and create a new file by pasting in the selected time segment using the <Edit> <Paste Insert> menu command.  Then export this smaller WAV file.
  • Exporting a 16 bit WAV file to either a ASCII or Binary 8 bit file will rescale the data to fit within the 8 bit sample range.
  • The Universal File Format allows you to export multiple wave files to a single UFF file
