Introduction

Settings

Settings are persistent files located in the Settings folder of the User Home Folder. They consist of a number of basic and expert settings. There is no ideal solution to get an optimal analysis or synthesis, but these settings may be a goog start before refining you own parameters.

Available Settings

Factory Settings

These are the standard "average" default settings of AS.

Instrumental Settings

The parameters of the instrumental settings are designed for an optimal analysis, corresponding to the instrument's behaviour. Some settings, like the clarineet, use transients preservation for instance, whereas other like the flute, don't.The expert settings of these categories have been especially specified to get a good F0 estimation.

Monophonic and Polyphonic Settings

Polyphonic settings have a higher FFT window size than polyphonic settings. They are designed to be used with signal containing several sources.

Monophonic settings are especially efficient with signals containing a single source, but resonances or reverbaration may alter this monophonic quality, from the analysis point of view. In this case, the window size should be increased. A compromise should be found to get a good time and frequency resolution though.

Managing Settings

New settings can be saved and loaded for a subsequent use.

Save Settings As...

This command allows to save your current settings as new settings. They can then be loaded again for a subsequent use.

  1. Choose Save Settings As... in the Setting menu.

  2. By default, you will be offered to save the settings in the Settings directory of the User Home folder.

  3. Choose a name and a possible location for the new settings

  4. Press OK to validate.

Some settings have been modified and saved, and are represented as text files.

Save Settings

This command allows to save modifications of existing settings.

  1. Choose Save Settings in the menu.

  2. No dialogue window will appear.

Note that modifications of the AS settings can also be saved, which cannot be undone once you have quit AS.

Load Settings

This command allows to load settings that were saved as a persistent file.

  1. Select Load Settings

  2. The same dialogue window will open, displaying the contents of the Settings directory

  3. Select a file and press OK.
