HARMONIZER EXAMPLES
ECMC PVC example file harmonizer1

ECMC PVC example "harmonizer" is a mix of two soundfiles, created by example
scripts "harmonizer1-1" (first note) and then "harmonizer1-2" (which
created the second note).

Example PVC script file >> harmonizer1-1 << : 
A 4 note dominant 7th chord (cc2 / g3/ bf4/e6) is created
from a source violin tone. Each of the 4 "harmoinzed" notes
contains the full frequency spectrum of the source violin tone
(the -1 low and high frequency parameter arguments in the lines below:
Note: Do not include any comments (#) in the lines that create a
harmonizer map file
The following parameter values, written into the scratch file
$SFDIR/harmonizermap, create 3 "harmonizer" notes with transpositions
down 19 semitones (c2), up 15 semitones (bf4) and up 33 semitones (e6)
with gain adjustments of +9 dB, +4dB and -3 dB
echo \
\
-19         -1  -1   9 \
15	    -1  -1   4  \
33	    -1   -1  -3 \
\
> $SFDIR/harmonizermap
HARMONIZER_shift_file=harmonizermap
 
This function creates a master gain that increases linearly from -40 dB to 
-6 dB, and then decreases back to -40 dB, creating an amplitude swell
in all 4 notes:
gen3 -L1000 -40 -6 -40 > $SFDIR/gainfunc
MASTER_gain_in_decibels=$SFDIR/gainfunc  # int,float or FUNC

The "source" tone g3 is reduced in amplitude by 6 dB:
SOURCE_gain_in_dB=-6 # -0  # int,float or FUNC
 -  -  -  -  -  -  -
Example script "harmonizer1-2," which produced the second note in
/sflib/x/soundfile "harmonizer1," is identical to example "harmonizer1-1"
 except that only a portion of the frequency spectrum of the original violin
tone is used for resynthesis of each of the 3 harmonized notes:
echo \
\
-19         -1  9.00   9 \
15	    8.03  10.02   4  \
33	    9.07   -1  -3 \
\
$SFDIR/harmonizermap

HARMONIZER_shift_file=harmonizermap

Harmonized tone c2 is created from frequencies between 0 Hz (-1) and
c5 (9.00) in the source violin tone
Harmonized tone bf4 (15) is created from frequencies between ef3 (8.03)
and d6 (10.02) in the source violin tone.
Harmonized tone e6 (33) uses frequencies from  g5 (9.07) to the Nyquist
