Note The Consonant Speed(β) in (8) is a feature added in Ver0.2.61. Please note also that Ver0.2.61 and after don't work unless you use the provided resampler.exe. (The old generic version resample5 and the development versions resample7 and 8 are ignored.)


Number Function name Feature Description
1 Lyrics Display lyrics. (Can be changed manually in the text box)
2 Key Show the pitch. (Can be changed by the pull-down)
3 Length Displays the length of the note in tick units (quarter note = 480. (Tick units can be set manually)
4 Volume Can be adjusted between 0% .. 200%, manually or by the up and down arrow buttons. (Base value is 100%)
If the P flag is set to 100 in "Flags", 200% is 0dB, 100% is -6dB, 50% is -12dB. (See below for the P flag)
5 Modulation The modulation is a function altering the changes in the pitch (the sound height) of the primary sound. (It is equivalent to setting the depth of the pitch bend in VOCALOID2.)
It can be adjusted between -100%..200%, manually or by the up and down arrow buttons. 10/05/26 Fix: A deleted value, set to a blank, is treated as a 0% value, where no alteration is applied to the primary sound pitch changes, which remain as-is.
When the 0% default value is entered, the pitch stays the most steady. If you use a continuous source sound, always leave it at 0% for the sound coupling to be properly performed. If the sound is alone, however, increasing the value of the modulation can prevent the pitch from being too leveled and sounding too mechanical. (Beware that when raising it up to 100%, most of the primary sounds become pretty off-key.)
6 Preutterance Can be manually set in milliseconds (in micro-seconds after the decimal point).
7 Overlap Can be manually set in milliseconds (in micro-seconds after the decimal point).
8 Consonant Speed (β) This feature scales the pronunciation time of the consonants by changing the playback speed of the section set in Fixed range of the consonant part in Voice settings. (This corresponds to the velocity in VOCALOID2.)
Blank or 100 means no changes. The value can be set between 0 to 200.
A value greater than 100 increases the playback speed, and the consonant pronunciation time is shorter. With the maximum value 200 the playback speed is doubled (the pronunciation time is halved). (By setting this way, you may prevent the articulation of consonants reduced due to STP (17) adjustments from becoming bad, with sounds in which the preutterance is long like e.g. the "sa" or "ha" columns.)
A value smaller than 100 slows down the playback speed, and the consonant pronunciation time is longer. With the minimum value 0 the playback speed is halved (the pronounciation time is doubled). (By setting this way, you may be able to improve the articulation of the short part in consonant sounds like e.g. the "ka" and "ta" columns.)
9 Clear button

Button to clear the value of Preutterance (6) and Overlap (7). (Used mostly when using continuous sound sources.)

10 Reset

Button to enter in Preutterance (6) and Overlap (7) the values of the current lyric primary sound. (Not displayed if more than one note is selected.)

11 OK button

When the settings are finalized, press OK to close the Settings screen.

12 Cancel button

To cancel the setting changes, press Cancel to close the Settings screen.

13 Details/Hide button This button displays or hides the features (14) to (18).
14 BRE (Breathiness) This parameter adds a breath component (a sense of breath) to the voice.
It can be manually set between 0 and 100. If blank, it takes the base value 50. The greater its value, the greater the breath component and the breathing sensation.
※ When using breathing sounds, this can limit the deterioration of sound if set to 100.
15 No Formant Filter If checked, suppress the automatic formant adjustments which are normally performed.
Use this when a sound other than human voice, like e.g. a musical instrument, was used in the primary sound.
16 Flags An input field for flags controlling the type of voice, like e.g. "g", "Y", "H", "h".
For the features of the various flags, please refer to 7-3. Setting the Flags or to UTAU users mutual aid@wiki.
17 STP This feature subtracts milliseconds to the head of the preutterance.
In order for the preutterance not crushing the preceding note, the length of the preutterance is automatically reduced so that at least half of the length of the preceding note is remaining.

18 Others button A button to output in a text screen the current settings of the envelope and portamento.
This too allows changing the settings by directly entering numerical values in the text screen, but this is not generally used.

7-3. Setting the Flags


In UTAU, you can perform a variety of tonal marks by entering various flags like "g-5H30Y0" in the "Flags" text box of "Sound Properties" 「音のプロパティ」.

Note: You must enter half-width uppercase or lowercase letters in Flags. Also please note that the case is significant (uppercase and lowercase are different types of Flags).

In addition, there are Flags that are valid with all the resamplers (singing synthesis engines), and flags that are valid only for the latest generic Resampler version and for the development versions (resampler7, resampler8).

All the valid resampler Flags:

Flag Base value Setting range Feature - How to it set up effectively
g 0 -100 .. +100

A flag to control the effect offered by the formant (the voice quality determined by the structure of the throat or mouth). (Strictly speaking, this is different from VOCALOID2's gender factor, but it has the same effect.)
Make sure to set this flag value with the + or - symbols appended, like e.g. g+10, g-10.
When setting positive values, the voice becomes deeper, more mature and masculine (with +20 or more, a female voice can become male.)
When setting negative values, the voice becomes thinner, more childlike and feminine (with -20 or less, a male voice can become female.)

t 0 -9 .. +9

Flag to adjust the pitch in 10 cents (1/10th of semitone) units. Make sure to set values with the + or - symbols appended, like e.g. t+5, t-5.

Y 100 0 .. 100

The part outside of the fixed range in consonants is called breathiness. (Details are omitted.)
By specifying a small value like e.g. Y0, the breathiness part of consonnants becomes relatively stronger, and the articulation is considered to be better. (As a side effect, noise appears that makes high notes sounding metallic, thus increase the flag value, or adjust simultaneously the H low-pass filter described below.)
Note: If you use a continuous sound source, specifying a small value like e.g. Y0 causes noise, so please leave it to the default value Y100. Reference -> About UTAU: Improving the articulation by just adding the magic option "Y0"

H 0 0 .. 99

A low-pass filter to emphasize the bass and cut the treble. (When using together the C, D, E low-pass filters described below, they produce the same effect.)
It has the effect of mitigating the metallic noise on high notes, but as a side effect the sound becomes muffled.

h 0 0 .. 99

A low-pass filter operating outside of the breath component of consonant (breathiness). As it emphasizes the high frequencies of consonant components, it is unsuitable to sound sources where the consonant component is unstable.
Note: If set too strong, voices becomes hoarse even with sound sources in which the consonant component is stable, and you need to reduce the value of the Y flag.
Reference -> About UTAU: Development version 7.1

F 3 0 .. unspecified

This adjusts the stength of the formant filter. The formant filter depends on the frequency defined by "source frequency * specified value".
It is generally better not to touch it, but when noise appears in low tones, you can suppress it by specifying values around F4 .. F7.
This flag is valid for Resampler development versions too, but changes are not as big as in the default generic Resampler version.

L None 0 .. unspecified

A fixed frequency for the "F" flag above. The formant filter depends then on the frequency defined by "170Hz * specified value".
When used simultaneously with F, this value takes precedence.

Flags that are valid only for the latest generic and the development Resampler versions:

Flag Base value Setting range Feature - How to it set up effectively
b 0 0 .. 100

BRE adjustment after the formant filter.
BRE changes are loosened when its pitch is very different from the pitch of the primary sound, and the voice becomes unpleasantly rough.
In addition, because it is not influenced by the low-pass type filters (C, D, E, H and h), the sound coming from BRE is bad and muffled.

C 0 0 .. 100

A low-pass filter especially reducing the high-frequencies.
When set to 100, the volume is 100% at 0kHz, 50% at 11kHz, and 0% at 22kHz.

D 0 0 .. 100

A low-pass filter cutting the midrange.
When set to 100, the volume is 100% at 0kHz, 0% at 11kHz, and 100% at 22kHz.

E 0 0 .. 100

A low-pass filter cutting the bass and treble.
When set to 100, the volume is 100% at 0kHz, 0% at 7.1kHz, 100% at 11kHz, and 0% at 22kHz.

c 50 0 .. 100 The value of the C flag before the formant filter adaptation.
P 86 0 .. 100

Peak compressor. Align the peak volume of the primary sound. (The volume setting and the envelope changes are applied separately.)
There is zero variation with a value of 100. When set to 99 or less, the variation produced is proportional to the volume of the primary sound and to the parameter value.
Because only the peak volume of the primary sound is aligned, a sense of instability in the volume will remain in sound sources with unstable volume changes, even if it is set to 100.

W unspecified unspecified Produces a robotic voice. This flag is highly experimental, and is generally not used.

7-4. Setting default values for "Note Properties"


A base value is set in "Note Properties" and Flags, but the default value of the Properties and Flags that are set when entering notes can be changed in the "Note default settings" screen. However please note that the Properties and Flags of the notes that were already entered before changing the settings in the screen, are not modified.

How to open the "Note default settings" screen: open "Note Default" 「音符のデフォルト」 from the "Tools" 「ツール」 menu, then select "General" 「基本設定」.

7-5. Setting flags in the "Project Settings" screen


Click "Project Properties" 「プロジェクトのプロパティ」 from the "Project" 「プロジェクト」 menu to open the "Project Settings" 「プロジェクトの設定」 screen, and directly input the Flags value, like e.g. "g-5H30Y0", in the "Rendering Options" 「生成時オプション」 field. When pressing "OK" to close, the Flags apply to all the notes of the whole project.

※ Please note that even after applying "Rendering Options" 「生成時オプション」, the Flags input field in the "Sound properties" 「音のプロパティ」 screen remains blank. In addition, if a value is entered in the Flags input field of the "Sound properties" 「音のプロパティ」 screen, this latter value takes precedence.
