RE-SAMPLING
The re-sampling page (called RATE on the soft key because we didn’t have enough room!)
allows you to re-sample your sounds at different sampling rates. This is to allow you to sample at
anything other than 44.1kHz and 22.050kHz and to save memory. High sampling rates and
bandwidths are all well and good but if the sound doesn’t have a high harmonic content, what’s
the point of wasting valuable memory? For example, you would be justified in using a high
sampling rate for cymbals and hi-hats with their high harmonic content but for bass drums,
toms, amplified electric guitars and the like whose frequencies may not extend beyond 10kHz,
it seems pointless. Of course, this kind of sound can be set to be recorded at 10kHz in the
SAMPLE pages but what if the sound needs a bandwidth of 12 or 14kHz? This is where the re-
sampling or RATE page comes in.
Pressing in the DSP pages calls up this screen:
As usual, the sample name and free memory are displayed on the top line.
This shows the selected sample’s sample rate. This field is not
accessible.
This allows you to set the sample rate of the new sample you wish
to create. This is variable between 22050Hz (22.050kHz) and
65000Hz (65kHz). There may seem little point in re-sampling
upwards but it might come in useful if you need to transfer a
sample via a sample editor to a sampler that uses a higher sample
rate. The default for this field is 22050 (half bandwidth) but can be
set as you like. This field also works in conjunction with the
and which enter three quarters and two thirds the sample’s
original sample rate.
This allows you set the quality of the re-sample. Higher quality
values will analyse the signal more closely thereby producing
better results. Higher quality re-sampling does take longer,
however.
This shows the length of the new sample. As usual, as in all pages
of EDIT SAMPLE, you may view this in milliseconds by pressing
the RATE key again.
This shows the new tuning. When sounds are re-sampled, they
must adopt a new tuning. This is because, when you re-sample at,
say, half bandwidth, you take out half the data making it play at
twice the pitch so it is necessary to offset the tuning. This is done
automatically for you and this field is not accessible.
