one or several applicable conversion options, affecting the resulting ringtone. Options are space-separated. The list of applicable options for each format follows:

FIND-CYCLES – Ringtone Creator tries to locate cycles in the ringtone and potentially increase the amount of music information stored in the given number of bytes.
Applicable to: RTTTL, NOKIA, NOKIATXT, IMELODY

SCALE-ALWAYS – put scale numbers for each note; don't assume that the scale once being set remains in effect for the subsequent notes. For IMELODY formats default notes(4th octave) have not sclae numbers.
Applicable to: IMELODY, IMELODY 10, NOKIA, NOKIATXT

PERSISTENT-SCALE – put scale number for note if there is changing between octaves;
Applicable to: IMELODY, IMELODY 10

SCALE-ALWAYS+PERSISTENT-SCALE – put scale numbers for each note besides default notes(4th octave). In changing to 4th octave it puts scale number to first 4th octave note. Using both option is default.
Applicable to: IMELODY, IMELODY 10

COMPACT – Ringtone Creator tries to compact a ringtone by dropping out all the extra information (not affecting the sound quality, though). For certain ringtones, the compact ratio reaches up to 40%.
Applicable to: IMELODY, MIDI 0, MIDI 1, MIDI SP, EMELODY

FORBID-SAVE – Disallow saving a ringtone once it's being downloaded to the client's mobile phone (Preview Mode).
Applicable to: SMAF MA1, SMAF MA2, SMAF MA3

MONO, STEREO – Set number of channels in the produced wave. MONO can be used in conjunction with mixing mode settings (see below).
Applicable to: WAVE, MP3

LEFT-CHANNEL, RIGHT-CHANNEL, MIX-CHANNELS – mixing mode for STEREO to MONO conversions.
Applicable to: WAVE

SAVE-TRIPLETS – saves triplets in output iMelody file. Some terminals recognize “;" character and other don't.

Options can be mixed, for example, you can choose to set the SCALE-ALWAYS option for your IMelody ringtone, but at the same time to reduce it's size using COMPACT and FIND-CYCLES option. Options are separated with a single space:
SCALE-ALWAYS COMPACT FIND-CYCLES

this parameter is very important as it allows performing modifications to the ringtones and retrieving extra information. The list of modifying actions follows:

TP – truncate maximum instant polyphony of a ringtone. For example, you may get a 16-channel file with instant polyphony of 4.
Example: TP4

TC truncate the number of channels in a polyphonic ringtone. For example, if a recipient's phone supports only 4 channels and the source ringtone contains 14 channels, you will have to perform this operation.
Example: TC4
TC1 produces a monophonic ringtone.

Truncate Channels and Truncate Polyphony should always come in pair and in the following order: TC first and then TP.

SN – set the song name. Long names are allowed, but be aware that some phones have certain limitations on the length of the song name. For example, it's a really bad practice to give a monophonic song a name longer than 15 characters.
Example: SNMy Muzikk

LT – limit the duration of a ringtone to fit or to get as close as possible to the given number of milliseconds. For polyphonic ringtones, it affects all channels.
Example: LT30000
This instruction sets a limit of 30 seconds.
It is also possible to extract middle part of the melody. In this case you need to specify start point and end point in milliseconds delimited by the colon. You can also omit any of the points. If start point is omitted the melody is extracted from the beginning. If end point is omitted the melody is extracted up to the end.
Examples: LT10000:20000 extracts melody from 10th to 20th second, LT10000: extracts melody from 10th second up to the end

LI – limit the number of notes in a ringtone. With polyphonic ringtones, it first modifies the leading track and then all other tracks accordingly.
Example: LI20
set the number of notes to 20.

LS – set the maximum file size of a resulting ringtone. Extremely useful when you deal with ringtones transmitted over SMS.
Example: LS128
ensure that the output ringtone size will not exceed 128 bytes.

VO – adjust the relative volume of a ringtone. Byte. Takes a value in a range of -127 to +127. -127 means silence and +127 – maximum loudness.
Example: VO30
increase the volume by 30 volume units (100% is 127 units)

GD0 – get duration of a ringtone. The important thing to know is that this method returns just the result code + status code + duration of a ringtone (in ms). All other processing parameters are ignored if this parameter is specified.
Example: GD0

FT – adds fade out effect to silence during last milliseconds
Example: FT1000
Explanation: Output ringtone will have fade out effect to silence during last 1 second

FI – adds fade in effect to volume of ringtone in time specified as parameter during first milliseconds
Example: FI2000
Explanation: Output ringtone will have fade in effect to volume of ringtone in 2nd second during first 2 seconds

Actions can be combined using a pipe sign like this: TC4|TP4|LS16384
