Delete
Delete the currently playing file. The file will be deleted but the playback of the file will
not stop immediately. Instead, the part of the file that has already been buffered (i.e.
read into the player’s memory) will be played. This may even be the whole track.
Pitch
The
Pitch Screen
allows you to change the rate of playback (i.e. the playback speed
and at the same time the pitch) of your player. The rate value can be adjusted between
50% and 200%. 50% means half the normal playback speed and a pitch that is an octave
lower than the normal pitch. 200% means double playback speed and a pitch that is an
octave higher than the normal pitch.
The rate can be changed in two modes: procentual and semitone. Initially, procentual
mode is active.
If you’ve enabled the
Timestretch
option in
Sound Settings
and have since re-
booted, you can also use timestretch mode. This allows you to change the playback
speed without affecting the pitch, and vice versa.
In timestretch mode there are separate displays for pitch and speed, and each can be
altered independently. Due to the limitations of the algorithm, speed is limited to be
between 35% and 250% of the current pitch value. Pitch must maintain the same ratio
as well as remain between 50% and 200%.
The value of the rate, pitch and speed is not persistent, i.e. after the player is turned
on it will always be set to 100%. However, the rate, pitch and speed information will be
stored in any bookmarks you may create (see section
(page
)) and will be restored
upon playing back those bookmarks.
