ampdbfs — Returns the amplitude equivalent of the decibel value x, which is relative to full scale amplitude.
Returns the amplitude equivalent of the decibel value x, which is relative to full scale amplitude. Full scale is assumed to be 16 bit. New is Csound version 4.10.
Here is an example of the ampdbfs opcode. It uses the files ampdbfs.orc and ampdbfs.sco.
Example 31. Example of the ampdbfs opcode.
/* ampdbfs.orc */ ; Initialize the global variables. sr = 44100 kr = 4410 ksmps = 10 nchnls = 1 ; Instrument #1. instr 1 idb = -1 iamp = ampdbfs(idb) print iamp endin /* ampdbfs.orc */
/* ampdbfs.sco */ ; Play Instrument #1 for one second. i 1 0 1 e /* ampdbfs.sco */
Its output should include lines like:
instr 1: iamp = 29203.621
