You can also move the selection cursor with the arrow keys or with the keys Home and End.

  • Samplerate: States with how many samples per second the sound was recorded.
  • Duration: Tells the duration in the format m:ss +SSS (minutes:seconds +milliseconds).
  • Channels: Files may have different channels, like mono, stereo or 6 channels, when it is a 5.1 recording. Only the first channel is displayed in the visualization canvas. The edited sound is always converted to stereo on saving.
  • Volume: The volume level of the original sound file before editing.

3.5.1 Peculiarities

Limitation

Soundpad is not designed to edit audio files, which are longer than 10 minutes. You may still do so, but you will see a warning message, which you have to confirm to begin editing.
The main reason for this is the huge memory consumption while working with uncompressed audio data.

It is acutally not a big deal, but you'll probably be more satisfied using another audio editor to edit big files.

File format

The preselected file format, when saving an edited sound, is the one, that is configured in the recorder preferences at File ▷ Preferences ▷ Recorder ▷ Save as. (See also: Recorder preferences).
