The User Home Folder allows to store sound files, files dealing with operations performed on sounds (analysis, treatments...), and files related to the application's behaviour (temporary files) and parameters (settings).
Sounds : AIFF, AIFC, Wav, SDII, 32 bit floating AIFC and WAV mono or multichannel files. Sound files resulting from a treatment in AS must always be named and saved in order to process the treatment, which will not affect the original file.
The data of the operations performed at a session can be saved in the directories of the User Home. There are four types of files: analysis (.sdif), treatments (.trt), and annotations (.mid). These files can be used again and modified.
There are many types of sound analysis, which address various characteristics of the signal. These can be accessed via the
Analysis menu. The corresponding analysis files are stored in spectific directories. The data of each analysis is stored in SDIF files.
Sonogram analysis including Fft, LPC, discrete cepstrum, reassigned spectrum, true envelope. These analysis lead to a visual representation of the spectrum.
.sdif binary file, can only be represented, not read in a text editor.
Fundamental frequency analysis
.f0.sdif, can be converted into text file.
Chord sequence analysis
Spectral segmentation or manual markers
Peak detection, formant analysis, masking effects
-formant.sdif, -mask.sdif, -peak.sdif
Files with no visual representation. Open with a text editor directly.
Markers can be created with the various analysis methods of AS, via the
files, such as filters, transposition, time stretch... Treatments are listed in the
Treatments menu, or represented in the tools bar of the sonogram window.
Some treatments, such as time stretch or transposition, are programmed with a BPF in the BPF editor.
Hence, BPFs can be saved as any treatments as

files, referring to MIDI annotations, notes or comments added in the sonogram.
Annotations cannot be open again in AS, but can be open and edited with a score editor, a sequencer, or a player, or assisted composition programs like OpenMusic...
These files shouldn't be modified.
A format for sound description data storage, including representations of the signal for analysis-synthesis like spectral, sinusoidal, time-domain, or higher-level models, sound descriptors like loudness or fundamental frequency, markers, labels, and statistical models.
his format allows to store unspecified sound descriptions or analysis with a strict and normalized structure.
