voice ― 음성 만들기

Syntax

ares  voice       kamp, kfreq, kphoneme, kform, kvibf, kvamp, ifn, ivfn

Initialization

ifn, ivfn — 2개의 table number로 carrier waveform 과  vibrato waveform이 요구된다.   아래의 files인  impuls20.aiff, ahh.aiff, eee.aiff, ooo.aiff 가 carrier로 적합하고 sine wave가 vibrato wave로 사용될 수 있다. 이 파일들은 요기에서 다운로드 가능

Performance

kamp — Amplitude

kfreq — 소리날 음의 Frequency (변화가능)

kphoneme — 0~16의 정수로서 formant를 결정

“eee”, “ihh”, “ehh”, “aaa”,

“ahh”, “aww”, “ohh”, “uhh”,

“uuu”, “ooo”, “rrr”, “lll”,

“mmm”, “nnn”, “nng”, “ngg”.

아래의 것들은 아직 불가능함.

“fff”, “sss”, “thh”, “shh”,

“xxx”, “hee”, “hoo”, “hah”,

“bbb”, “ddd”, “jjj”, “ggg”,

“vvv”, “zzz”, “thz”, “zhh”

kform — Gain(0.0~1.2)

kvibf — vibrato의 frequency  (0~12Hertz가 적당)

kvamp — vibrato의amplitude

Examples

Here is an example of the voice opcode. It uses the files voice.orc, voice.sco, and impuls20.aiff.

Example 417. Example of the voice opcode.

/* voice.orc */
; Initialize the global variables.
sr = 22050
kr = 2205
ksmps = 10
nchnls = 1

; Instrument #1.

  kamp = 3
  kfreq = 0.8
  kphoneme = 6
  kform = 0.488
  kvibf = 0.04
  kvamp = 1
  ifn = 1
  ivfn = 2

  av voice kamp, kfreq, kphoneme, kform, kvibf, kvamp, ifn, ivfn

  ; It tends to get loud, so clip voice’s amplitude at 30,000.
