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.
Decimation - this allows you to "down-sample" the wave data prior to exporting.
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.
Output Sample Values:
8 bit WAV data: 0...255
16 bit WAV data: -32767...+32767
24 bit WAV data: -8388607...+8388607
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 view 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.
