tone() function set level in dB

[hanfrunz]

Hello,

today i needed a -9db sinus-wave-tone. But the tone() function needs a value between 0 and 1. Here's a small function to calculate this value:


function dB2value(float dB) {
return Pow(10.0, dB/20.0)
}


you can then use it in a script like this:


function dB2value(float dB) {
return Pow(10.0, dB/20.0)
}

video=blankclip().converttoyv12()
audio=Tone(120.0, 1000, 48000, 2, "sine", dB2value(-9.0) )
audiodub(video,audio)
histogram("AudioLevels")


should'nt that be implemented to the source code of the filter?
In real life you use dB-values for sound.
