This document describes how to use audio wave files as the source for audio processing functions.
Preparing an Audio File
This option looks in the SPL Graph public folder for its files. All audio wave files that are stored from the SPL Graph module will be available.Dropbox
Dropbox is not currently supported for external wave files.Selecting a File
Files are selected
from the Input Sources page, which is accessed on the Setup page for the
individual function, or from the Input button on the SPL Pro main page.
Tap the "Select Input File" button to bring up a list of available files. Any wave files saved from SPL Graph, and any wave files that you have manually placed into that folder will also be shown in the list.
Tap the row that
shows the file that you wish to use, to highlight it. Then tap the
"Select File" button to open the file and make it available to the
function, such as FFT.
Audio File Navigation
On the main module screen, you will see a moving slider. This represents the relative current position in the audio file that is being processed. The file will be processed from the beginning to the end, and then the position will loop back to the beginning.
You can use the slider to change the current position in the file.
To return to
normal real-time audio processing, go back to the Input Sources page,
and tap the Clear button in the toolbar. The functions will return to
live audio processing.
