Statistics
The Statistics function on the Audio menu analyzes the
selected audio (events, clips or range selections) and dis-
plays a window with the following information:
About time stretch and pitch shift
algorithms
The Standard algorithm is optimized for CPU efficient re-
altime processing. The following presets are available:
If you select the “Standard – Custom” option, a dialog
opens where you can manually adjust the three parame
-
ters that govern the sound quality of the time stretching:
Item Description
Min. Sample
Value
The lowest sample value in the selection, as a value be-
tween -1 and 1 and in dB.
Max. Sample
Value
The highest sample value in the selection, as a value be-
tween -1 and 1 and in dB.
Peak
Amplitude
The largest sample value (in absolute numbers) in the se-
lection, in dB.
DC Offset The amount of DC Offset (see “Remove DC Offset” on
page 169) in the selection, as a percentage and in dB.
Estimated
Resolution
Even though an audio file is in 16 or 24 bits, it may have
been converted from a lower resolution. The Estimated
Resolution value makes an educated guess about the ac
-
tual audio resolution, by computing the smallest level dif-
ference between two samples.
Estimated
Pitch
The estimated pitch of the audio selection.
Sample Rate The sample rate of the audio selection.
Min. RMS
Power
The lowest loudness (RMS) measured in the selection.
Max. RMS
Power
The highest loudness (RMS) measured in the selection.
Average The average loudness over the whole selection.
Option Description
Standard –
Drums
This mode is best for percussive sounds, because it does
not change the timing of your audio. Using this option with
certain tuned percussion instruments may lead to audible
artifacts. In this case, try the Mix mode as an alternative.
Standard –
Plucked
Use this mode for audio with transients and a relatively sta-
ble spectral sound character (e. g. plucked instruments).
Standard –
Pads
Use this mode for pitched audio with slower rhythm and a
stable spectral sound character. This minimizes sound ar
-
tifacts, but the rhythmic accuracy is not preserved.
Standard –
Vocals
This mode is suitable for slower signals with transients
and a prominent tonal character (e.
g. vocals).
Standard –
Mix
This mode preserves the rhythm and minimizes the arti-
facts for pitched material that does not meet the above
criteria (i.
e. with a less homogenous sound character).
This preset is selected by default for audio that is not cat-
egorized.
Standard –
Custom
This preset allows you to manually tweak the time stretch-
ing parameters (see below). By default, the settings that
are shown when you open the dialog are those of the last
preset used (except if the Solo preset has been selected,
see below).
Standard –
Solo (Cubase
Elements only)
This mode preserves the timbre of the audio. Only use it
for monophonic material (solo woodwind/brass instru
-
ments or solo vocals, monophonic synths or string instru-
ments that do not play harmonies).
Parameter Description
Grain size The standard time-stretching algorithm splits the audio
into small pieces called “grains”. This parameter deter
-
mines the size of the grains. For material with many tran-
sients, use low grain size values for best results.
Overlap Overlap is the percentage of the whole grain that will
overlap with other grains. Use higher values for material
with a stable sound character.
Variance Variance is also a percentage of the whole length of the
grains, and sets a variation in positioning so that the over
-
lapping area sounds smooth. A Variance setting of 0 will
produce a sound akin to time stretching used in early
samplers, whereas higher settings produce more (rhyth
-
mic) “smearing” effects but less audio artifacts.
