Introduction

Storage Folders and Files

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

Sounds

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.

Accepted File Formats

Operations

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.

Analysis

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[1].

Directory Name

Analysis Type

File Type

Fft (Fast Fourier Transform)

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

Fundamental frequency analysis

.f0.sdif, can be converted into text file.

Chord Seqs

Chord sequence analysis

.cs.sdif

Vuv

Voiced/unvoiced analysis

.vuv.sdif, idem

Partials

Partial tracking

-trc.sdif, idem

Markers

Spectral segmentation or manual markers

.mrk.sdif

Spectral Estimates

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 Generate Markers menu, or used as simple marks in a sound files with a manual operation.

Treatments

Treatments: .trt files, such as filters, transposition, time stretch... Treatments are listed in the Treatments menu, or represented in the tools bar of the sonogram window.

Treatments : BPFs

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 .trt file in the Treatment directory.

  • They can also be saved as a SDIF or text files in any desired location of the computer.

More about BPFs
Annotations

Annotations: .mid files, referring to MIDI annotations, notes or comments added in the sonogram.

Annotation Files and AudioSculpt

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...

Communication with Other Programs

Settings and Temporary Files

These files shouldn't be modified.

Settings Files

Settings: . txt and sometimes. xml files. The Settings folder of the AudioSculpt application folder already contains a number of setting files, which refer to the factory settings of the application. Other setting files are created if new Expert Settings have been defined, when executing specific analysis or treatment for instance, and saved. Remember AS won't ask you if you wish to save your settings.

Temporary Files
The temporary file of a surface filter.
The temporary file of a surface filter.

Temp: Temporary files are often .sdif files used for operations like copy/paste, noise zones, or sound files. They mustn't be manipulated, at the risk of making the application unstable. They are deleted from the directory once the session is over. These files can possibly be edited once they have been moved to another dirctory.

  1. SDIF Sound Description Interchange Format

    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.
