MMC drives usually activate their own idea of speed and take MMC drives usually activate their own idea of speed and take the speed value
the speed value given by the burn program only as hint given by the burn program only as hint for their own decision. Friendly drives
for their own decision. 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
