W561XXX DESIGN GUIDE

(II) Timbre note must be G1/G2/G3/G4/....
(III) Because the Loop is played recursively, the junction between 'Loop's must be smooth.
Otherwise, the discontinuity of 'Loop's will causes a high frequency noise.
The Make-Timbre utility of Winbond Speech Wave Editor generates a timbre sample
from a *.src or *.wav file. According to the characteristics of different instruments, users may
adjust the following parameters to get a preferable timbre.
Timbre name
Users could enter less than 15 characters as the name of the timbre. Note that the timbre name
must not include the space character.
Timbre size
(1K, 2K, 3K, 4K, 6K, 8K, 10K, 12K, 16K samples)
It defines the total length of the timbre. If the size is larger, the synthetic sound is more similar
to the real instrument. Limited by the timbre table, the maximum size of a timbre is 16K
samples.
Loop size
(128, 256, 512, 1024, 2048, 4096 samples)
Users can select the loop size under the condition that the loop size is not greater than 1/4 of the
timbre size. When the timbre size is fixed, larger loop size provides more similar and colorful
synthetic sound than that of small loop size. However, large sized loop is not always good.
For some timbres, a tremolo effect occurs when large sized loops are used. Under such
circumstances, users should choose small sized loops to generate more stable synthetic
sound.
Note sustainment (1/4, 1/2, 1, 4/3, 2, 4 seconds)
It defines the period during which the note sustains. A short note sustainment means the
envelope of output sound decays fast. Users should select the note sustainment parameter
according to the characteristics of the instrument. For example, the note sustainment of a
piano timbre may be 2 seconds while that of a violin timbre may be 4 seconds.
Fundamental period
(4, 8, 16, 32, 64, 128, 256, 512 samples)
It indicates the fundamental period of the waveform. The default value is computed by software.
If needed, user can modify it.
Pitch
(G1, G2, G3, G4, G5, G6)
It denotes the position on the keyboard of the recorded timbre. Winbond provides timbre libraries
of 3 pitches, G3, G4 and G5. (Middle C is denoted as C4.)
Effect type setting (None, Effect1, Effect2, Effect3, Effect4)
It denotes the envelope effect of the synthetic sound of this timbre sample. The following is the
description of each selection.
None
-- No envelope effect added on the synthetic note.
Effect 1
-- An 1.5 Hz, 40% of depth, sine shaped envelope effect is added on the synthetic note.
Effect 2
-- A 3 Hz, 60% of depth, sine shaped envelope effect is added on the synthetic note.
Effect 3
-- A 4.5 Hz, 80% of depth, sine shaped envelope effect is added on the synthetic note.
Effect 4
-- A 6 Hz, 100% of depth (in full swing), sine shaped envelope effect is added on the
synthetic note.
Note that the sine waveforms of the 4 envelope effects are also stored in the timbre table as well
as the timbre samples. If any timbres with envelope effect are used in a *.out program, the
last 1 Kbytes of the 16 Kbytes timbre table will be filled out by the sine waveform. Therefore,
only 15 Kbytes are available to store the timbre samples. On the contrary, if no effect-added
timbre is used in the *.out program, 16 Kbytes are available for storing the timbre samples.
