#X text 11 23 linear amplitude to dB for audio signals;
#X text 99 281 The [rmstodb~] object converts from linear ("RMS") amplitude
to decibels \, so that an "RMS" of 1 corresponds to 100 dB. Zero amplitude
(strictly speaking \, minus infinity dB) is clipped to zero dB.;
#X text 99 518 This object takes an audio signal as input and output
(and works sample by sample). Since it calls a library math function
\, it may be much more expensive than other workaday tilde objects
such as [*~] and [osc~] \, depending on your hardware and math library.
