#X text 23 245 Finally \, dbtopow and powtodb convert decibels to and
from power units \, equal to the square of the "RMS" amplitude.;
#X text 304 448 updated for pd version 0.40.;
#X text 21 53 The mtof object transposes a midi value into a frequency
in Hertz \, so that "69" goes to "440". You can specify microtonal
pitches as in "69.5" (a quarter tone higher than 69). Ftom does the
reverse. A frequency of zero Hertz is given a MIDI value of -1500 (strictly
speaking \, it is negative infinity.);
#X text 22 149 The dbtorms and rmstodb objects convert from decibels
to linear ("RMS") amplitude \, so that 100 dB corresponds to an "RMS"
of 1 Zero amplitude (strictly speaking \, minus infinity dB) is clipped
to zero dB \, and zero dB \, which should correspond to 1e-04 in "RMS"
\, is instead rounded down to zero.;
