AudioExplorer Objects and Associated Files
Each of AudioExplorer's objects is associated with a directory and/or a set of files. The table below describes these associations and the types of files generated and maintained by AudioExplorer.
Many of AudioExplorer's files start with a number described below as <source-file hash>. In all cases, "<source-file hash> is a hash-code derived from the filename of the original audio source (e.g., a .wav file). This naming convention assures that AudioExplorer will assign unique names to all of its data files.
| Object Type | Corresponds to... |
|
Main Project |
Directory named "<name>.prj", where
<name> is the main project's name.
The main project directory is a sub-directory of the system directory selected in AudioExplorer's System Project configuration dialog. |
| Project | Directories named "<name>.prj", where
<name> is the project name.
Project directories are sub-directories of the main project directory. |
| Audio File | Files named <source-file hash>_<name>.pxdata.
"pxdata" is shorthand for "presentation data". This file contains statistics derived from the source audio data that allow the WavePanel to rapidly display the waveform at any zoom factor. |
| Note Map | Files named <source-file hash>_<name>.nsp and
<source-file hash>_<name>nsp.bmp.
The .nsp file contains data that AudioExplorer uses to generate dynamic notemaps and to display MIDI and note-region overlays. The .bmp file is the static bitmap associated with the notemap. Envelopes associated with notemaps are stored in "Envelope.xml". |
| Spectral File | Files named <source-file hash>_<name>.spec.
These files, which can be quite huge, contain complete frequency spectra calculated for every sampling interval defined in the Fourier/PSA configuration dialog. |
| Frequency Map | Files named <source-file hash>_<name>.fmhd and
<source-file hash>_<name>.bmp.
The .fmhd file contains header information which describes the source and properties of the frequency map. The .bmp file is the actual bitmap image. |
