Gilderfluke&Co 8 Bit Digital Audio Systems - Manual (Page 73)

Any of the previously ÔADDedÕ sample files can be highlighted on the
SNDCMP8 main window. The length of the sample will then be displayed
and you can set the Sample and Filter Rate, Silence Threshold and
Rounding for each sample. If more than one sample is selected the
Sample Length will change to show the total length of all the selected sam-
ples. Any changes will effect all the selected samples.
The following settings are available for each sample in a set:
1) Sample Rate: There are seven Sample Rates available for the final
audio files. These are:
15 KHz
10 KHz
7.5 KHz
5 KHz
3.75 KHz
3 KHz
2 KHz
With the exception of when you are recording a Ôsilent spielÕ or sub
woofer rumble, it is rare to use sample rates below the 5 KHz band-
width. The Sample Rate is virtually always equal to or above the
Filter Rate that is set for a sound. Two KHz Sample Rates are occa-
sionally used when you want to convert a sound into a long silence
to be used to generate a delay on a looping AB/DR-50. In this case
you would probably use a 2 KHz Sample Rate and 0 KHz Filter Rate.
2) Filter Rate: There are eight Filter Rates available for the final audio
files. These are:
15 KHz
10 KHz
7.5 KHz
5 KHz
3.75 KHz
3 KHz
2 KHz
0 KHz (absolute silence)
The Filter Rate is virtually always set to be equal to or below the
Sample Rate that is set for a sound.
3) Silence Threshold: Sounds that are going to be programmed into
an AB-100 and AB-Clock can have all the ÔsilentÕ portions of the
sound removed from the final Eprom set. The reason you may want
to do this is to reduce the amount of Eproms the samples will use.
The threshold must be determined by trial and error. With a clean
digitally mastered original sound you can use a threshold of two or
three. If the sound is from a noisy source or analog audio tape you
will need to use a higher threshold. Silence removal can not be used
with AB/DR-50 MiniRepeaters.
4) Silence Threshold On/Off: Sounds that are going to be pro-
grammed into an AB-100 and AB-Clock can have all the ÔsilentÕ por-
tions of the sounds removed from the Eprom set. The reason you may
want to do this is to reduce the amount of Eproms the audio will use.
This checkbox is used to turn the Silence Removal feature on and off.
Silence removal can not be used with AB/DR-50 MiniRepeaters.
5) Round Sample Down: Sample lengths on our eight bit repeaters
must be at an even one KByte boundaries in the Eprom(s). This
checkbox is used to select whether the sample length will be round-
