When clicking on one of the samples of a .sf2 file in the tree, the page of the sample edition appears.

This page is divided into several parts:

The graph

The graph allows the visualization of the sound wave. It is possible to zoom vertically and horizontally by holding a mouse right click:

A green vertical bar indicates the start position of the loop (changeable by left click), a red bar indicates the position of the end of the loop (changeable by right click). A dotted line representing a wave portion is associated with each vertical bar, allowing us to visualize the superposition of the beginning and the end of the loop.
During playback, a white vertical bar runs the graph and indicates the playback position in real time.

Information

This section allows the edition of the following information:

In addition, the sample size in samples (number of values) and seconds is shown.

Note: any change on a stereo sample may be applied on the linked sample if the option is ticked in the preferences.

Frequencies

The Fourier transform is displayed as well as the list of dominant peaks (intensity relative to the maximum frequency, corresponding key number and correction). From these data, an estimate of the sound pitch is made. This estimate can be used as a basis for tuning.

Equalizer

The equalizer makes it possible to increases or decreases certain frequencies, from -15 to 15 dB. The effect is applied after pressing the "Apply" button. Pressing "reset" resets all the buttons to 0 dB (but does not remove the effect on the sound: for that use the "redo" button).

Note: any change on a stereo sample may be applied on the linked sample if the option is ticked in the preferences.

Player

The player plays the sound. During playback, a white cursor traverses the graph to indicate the playback position. Playback options are:
