INHARMONATOR EXAMPLES

ECMC notes by A. S. on using the
 PVC program "inharmonator" :

IMPORTANT NOTE: Currently the Linux version of the  inharmonator
program  is BROKEN, and inharmonator can only be used on the
ECMC SGI systems. However, many (though not all) of the sound
modification resources of inharmonator can also be achieved by
using "chordmapper," which is available on the ECMC  Linux as
well as SGI systems. For example, compare ECMC PVC example
"inharm1", and its 4 sources, "inharm1-1, inharm1-2, inharm1-3"
and "inharm1-4" with "example "chordmapper3" and its 4
sources ("chordmapper3-1" through "chordmapper3-4").


Frankly, I do not understand completely how a couple of the important
parameters in this program work, so there is an element of
heuristic trial-and-error in using "inharmonator."

The program allows one to alter the frequency and amplitude of any
number of partials within the source sound. Partials to be altered
are called the TARGETS, and the remaining (unaltered) partials
are called the NON_TARGETS in several of the parameter names.

However, the amount by which a partial is shifted in frequency (pitch)
results from a combination of two parameter arguments, leading to
complication and, often, difficulty in determining the exact amount
of the frequency shift.

(1) The first argument you may want to adjust is
   INHARMONATOR_fundamental_frequency=500  # int, float or FUNC
for which the inharmonator.tp template provides these comments:

 #  IMPORTANT: If possible change the default value of 500 above
  #  to the fundamental frequency, in herz, of the input soundfile
  #  Use the "midinote" command, or else consult the help file "herz"
  #  to determine this frequuency
  #  For inharmonic sounds, try changing the 500 default to various other
  #  values, and choose the value that provides the best result

(2) Next, determine the method to be used to specify frequency shifts.
Three alternative methods are available. The method to be used is
determined by the
  SHIFT_METHOD_multiplier_0_or_frequency_map_1_or_pitch_map_2=0
parameter:
   (1) If set to 0, the default, frequency shifts will be specified
       as multipliers. A value of .5 would shift the partial down
       an octave, a value of 1.5 up a perfect 5th, and so on.
   (2) If the SHIFT_METHOD argument is set to 1, the shifts are specified
       in herz
   (3) If the SHIFT_METHOD argument is set to 2, the shifts are specified
       in octave pitch class notation (e.g. 8.00 = middle C = 261.6 hz.
However, whichever of these 3 methods is used, the frequency shifts
also will be affected by the
     INHARMONATOR_fundamental_frequency
value discussed in step (1) above.

(3) Next, create a TARGETS SHIFT file by editing the template provided
in the following portion of the inharmonator.tp script:

   #*****TARGETS SHIFT FILE: DATA FORMAT
   # Edit the template table below, changing the 3 values for each partial
   # and adding or deleting lines to specify more or less than 10 target# partials. Do not include any comments within this function definition.
   # 1) partial number
   # 2) shift
   # 3) decibels

   echo \
   \
   1       1           -0 \
   2       1           -0 \
   3       1           0 \
   4       1           -0 \
   5       1           -0 \
   \
   6       1           -0 \
   7       1           -0 \
   8       1           0 \
   9       1           0 \
   10      1           0 \
   \
   > $SFDIR/inharmonatorfile ;

This template-within-a-template specifies 10 TARGET partials -- partial
numbers 1 through 10, the lowest 10 partials of the source sound,
beginning, I think, with the
     INHARMONATOR_fundamental_frequency
frequency.
frequency.
If you want to specify fewer than 10 target partials, delete some
of these  lines.
Then, for each of the target partials, edit one of these lines, changing
the default values (which will produce no alteration in the source
spectrum) to the 1) partial number, 2) the amount of frequency shift,
and 3) any change in the amplitude of this partial, expressed in dB

(4) Another importtant parameter is 
NON_TARGETS_gain_in_dB=-96
   # Range 0 to -96 (the default)
   # -96 provides the maximum possible suppresion of non-target partials
   # but does not provide complete suppression
   # 0 causes no attenuation in the amplitude of the non-target partials

(5) Although the parameters discussed above provide more than enough 
complication for most users, several additional parameters provide
further modification options that can be applied independently to
the target and and non-target groups of partials, or to the output
sound as a whole.

ECMC PVC example file inharm1

ECMC PVC and /sflib/x example "inharm1" is a linear mix of 4 source
examples:  inharm1-1, inharm1-2 inharm1-3 and inharm1-4
In all three examples the duration of the source violin tone is
cut in half and the output gain is reduced slightly to prevent
clipping in some of the examples.
The PVC program "chordmapper" provides many (but not all) of the same
sound modification resources available with "inharmonator." ECMC
PVC example "chordmapper3" is very similar to "inharm1," creating
the same modifications with somewhat different procedures. The
sources for these 2 examples also are very similar: inharm1-1 corresponds
to chordmapper3-1, inharm1-2 to chordmapper3-2, inharm1-3 to chordmapper3-3
and inharm1-4 to chordmapper3-4.

  -  -  -  -  -
"inharm1-1" creates straight resynthesis (no timbral alterations) of
the source violin tone.
The inharmonator frequency is set to 196, matching the fundamental
frequency of the source violin tone.

  -  -  -  -  -
In example "inharm1-2", the second tone, only partial one is altered.
This partial is shifted down a major seventh in frequency and its
amplitude is boosted by 12 dB. All other partials are attenuated (by
a specified value of 9 dB, although actually there is less attentuation
than this).

  -  -  -  -  -
In example "inharm1-3" the frequencies of partials 1 through 5 are
raised by increasing amounts (partial 1 is raised a minor ninth, partial
2 a major ninth, partial 5 an eleventh. The gain of these 5 target
partials by about 3 dB, while the gain of all other partials is attenuated
slightly.

  -  -  -  -  -
In example "inharm1-4" the inharmonator frequency is changed and
set to 392, double the frequency of the fundamental of the violin tone.
Odd numbered partial  frequencies are altered by ratios alternating
between a major 2nd lower and a major second higher than the original.

See the 4 source files ("inharm1-1" through "inharm1-4") for details.

ECMC PVC example file inharm2 ECMC PVC and /sflib/x example "inharm2" is a linear mix of 4 source examples: inharm2-1, inharm2-2 inharm2-3 and inharm2-4 In each of the 4 resynthesized tones 1) the duration of the original bassoon tone is reduced by 25 % 2) the INHARMONATOR_fundamental_frequency argument is set to 110, matching the fundamental frequency of input soundfile sflib/wind/bssn.a2 3) Even numbered partials 2 through 20 are defned as the target partials, but no frequency or amplitude alterations are specified for these target partials. Instead, a frequency SHIFT of +45 herz is applied to the 10 target partials TARGETS_frequency_shift=45 (shifting the frequency of each of these partials up by 45 herz) while a different frequency shift of -95 herz is applied to the remaining (non-target) partials NON_TARGETS_frequency_shift=-95 - - - - - - - - - Differences between the 4 resynthesized tones in /sflib/x/inharm2: In example file "inharm2-1" (which produced the first note in /sflib/x soundfile example "inharm2") no attenuation is applied to the non-target partials: NON_TARGETS_gain_in_dB=-0 - - - - - - - - - In example file "inharm2-2" (which produced the second note in /sflib/x soundfile example "inharm2") maximum possible suppression is applied to the non-target partials, resulting in a simpler timbre than in example "inharm2-1" NON_TARGETS_gain_in_dB=-96 # int, float or FUNC - - - - - - - - - In "inharm2-3" 2 out-of-phase functions, each with 3 peaks and 3 nulls, are created and applied to the gains of the target and non-target partials: gen5 -L100 3 1 0 | reshape -b-96 -B3 > $SFDIR/tremolo1 gen5 -L100 3 1 180 | reshape -b-96 -B3 > $SFDIR/tremolo2 NON_TARGETS_frequency_shift=-95 NON_TARGETS_gain_in_dB=$SFDIR/tremolo1 # int, float or FUNC TARGETS_frequency_shift=45 TARGETS_gain_in_dB=$SFDIR/tremolo2 # int, float or FUNC This results in 3 "cross-fades" between the 2 detunings of the bassoon tone. However, for reasons that are not clear to me, much of the original, unaltered bassoon spectrum remains. - - - - - - - - - In example file "inharm2-4" no frequency shifts are applied to either the target or non-target partials. Instead the target partials begin at the original pitch level, but then glissando up in pitch a half step. gen1 -L1000 0 0 .1 0 .9 1. 1. 1 > $SFDIR/rampup TARGETS_pitch_transposition_in_semitones=$SFDIR/rampup - - - - - - - - - Example file "inharm2-5" is similar to "inharm2-4," except that here a descending one octave glissando, beginning a major 7th above the original pitch level, is applied to the target partials and an ascending one octave glissando is applied to the non-target partials:
