than 52xCD, 24xDVD, or 20xBD, depending on the medium type.
MMC drives usually activate their own idea of speed and take the
speed value given by the burn program only as hint for their own
decision.
decision. Friendly drives adjust their constant angular velocity
so that the desired speed is reached at the outer rim of the
medium. But often there is only the choice between very slow and
very loud.
Sometimes no speed setting is obeyed at all, but speed is adjusted
to the demand frequency of the reading program. So xorriso offers
to set an additional software enforced limit by prefix
"soft_force:". The program will take care not to read faster than
the soft_force speed. This may be combined with setting the drive
speed to a higher value. Setting "soft_force:0" disables this
feature.
"soft_force:" tries to correct in subsequent waiting periods lost
or surplus time of up to 0.25 seconds. This smoothens the overall
data stream but also enables short times of higher speed to
compensate short times of low speed. Prefix "soft_corr:" sets this
hindsight span by giving a number of microseconds. Not more than 1
billion = 1000 seconds. Very short times can cause speed
deviations, because systematic inaccuracies of the waiting function
cannot be compensated.
Examples (combinable):
-read_speed 6xBD
-read_speed soft_force:4xBD -read_speed soft_corr:100000
