## Editing a Recording

To edit a recording, select a file in the recordings table and select "Edit Recordings..." from the Recordings menu. All changes are finalized if and only if the window is dismissed using the OK button. Several different methods of editing and viweing the file are presented.

### Changing the file format

The "Choose possible format" button allows one to select a sampling rate along with several other features. These settings are not applied, however, until this window is dismissed using the "ok" button and the "Change to Possible Format" button is clicked. This can be undone with the "Restore" button

### Applying Gain

The "Apply Gain" button takes a float value from the text dialog box immediately to its right and interprets it as a double. All samples in the file are multiplied by this value as soon as the "Gain" button is pressed. This can be undone with the "Restore" button.

### Normalizing file

This immediately scales the file such that the maximum value is 1.0 by applying the appropriate gain. This can be undone with the "Restore" button.

### Mix Down to One Channel

This mixes any stereo or higher recording into a mono recording. This can undone with the "Restore" button.

### Play

This button plays the file to the default sound output device

### Stop

Stops any playback that may be taking place.

### Restore

Restores the file to its original state.

### View Samples

This provides a mechanism for viewing all the samples of a recording. Note This takes a very long time to produce for all but the shortest files. The system is unresponsive in the meanwhile.

### Plot Samples

This provides a mechanism for viewing the samples in a graph. Note This takes a significant amount of time. Large recordings will cause the system to appear to hang while preparing the display.

### Plot Spectrum

This provides a mechanism for viewing the harmonic spectrum of the entire recording. Note This takes a significant amount of time to produce. Large files will cause the system to appear to hang while preparing the display.
