Resampler Flags

resampler.exe is the default resampler made by Ameya that comes with UTAU.

- Taken directly from https://utau-bowl.tumblr.com/post/647016314853097472/utau-flag-guide .
- Need to check how accurate this is (range values for t?) and word better (explain filters).
- Also find whatever names people use most for each flag to explain what they are.
Flag Name Range Default Description
a 100 Stretches or compresses the consonant part of a sample.
b [0-100] 0 Applies breathiness after synthesis. Is not affected by other flags (such as F)
B [0-100] 50 Applies breathiness before synthesis, and is affected by other flags.
c [0-100] 50 Sets value of C flag before formant filter adaptation.
C [0-100] 0 High pass filter
D [0-100] 0 Mid pass filter
E [0-100] 0 Low pass filter
F Formant strength 3 I think it can go up to 5 or so, beyond that it all starts to give similar results
g Gender [-100-100] 0 Positive values will deepen the voice, while negative ones will make it higher.
G Forces resampler to render .frq files before playing. This makes the synthesis process slower, but gives you new frqs.
H [0-99] 0 Emphasizes low tones, and cuts higher ones.
h [0-99] 0 Emphasizes higher tones, and cuts low ones.
L Sets a fixed frequency for F flag. Has no default value. Probably has the same limits as F flag.
N Formant on/off Turns the formant filter off.
P Peak compressor [0-100] 86 Compresses the voice to make the volume more consistent.
t Pitch 0 Shifts the pitch by a number of cents. 1 cent = 1/100th of a semitone.
W Produces a sharper and more metallic sounding voice. Flag is used by itself without a number added.
x [-100-100] 0 Affects a note depending on how the sample it takes from was recorded. Higher notes make the voice brighter, while low notes make the voice more muffled. Negative values affect the formant.
Y [0-100] 100 Controls the breathiness for the “vowel” part of a note.
