#X text 22 172 Boundary conditions are handled "reasonably". 100 db is assigned an RMS of 1 \, and [dbtorms~] and [dbtopow~] output true zero for 0 dB and less. See the help file for acoustic conversions of control data for more details on the conversions and boundary conditions., f 68;
#X text 22 84 These objects convert MIDI pitch to frequency and back \, and dB to and from RMS and power. The input and output are audio signals (and the conversion works sample by sample.) Since they call library math functions \, they may be much more expensive than other workaday tilde objects such as [*~] and [osc~] \, depending on your hardware and math library., f 74;
