  • Hey there!

    Can one LERP master volume from -99db to 0 db in a second or two? In that case whats the formula?

    Or is there a better idea for this?

    Thanks! ^_^

  • Hi.. I think there is fade volume action added in Audio plugin since R122 (C3 Runtime)

    Which is more convenience than lerp.. IMHO

    i am no LERP master volume but atleast this one thing i know ^_^...

    lerp(a to b in ticks/s) or lerp(a,b,x) lerp(0,-99,dt) lerp(-99,0,dt) fade out , fade in ... young obi kenobi.

    however i prefer the variable way, lerp sometimes snaps towards the end and i don't like that.

    also not sure if the volume has changed on decibels, but i think in Construct volume muted is -35db or nothing can be heard at that point, doing -99 is kinda pointless. unless again if that changed and you can actually hear stuff at -90db then -99db is a good value call.

    Edited: also above me there is a post ... with the new feature in C3 ... that might solve it for you, if you don't want any custom fade in fade out.

    Hey there! That option isnt there in C2.

  • Try Construct 3

    It wouldn't have been suggested if you had posted in the C2 section. ;)

    You can try rexrainbow's plugin, rex_audio_helper.

  • You can definitely hear -35db. It all depends on the quality of your headphones/speakers and what the volume of the imported sound file is. You can probably hear -50 to -60db with decent headphones, so I would go as far as -90db before considering it silent.

    oh that's new, i remember in C2 around -35 /-45 i couldn't hear nothing, maybe cause i had shitty headphones back then xD but the audio analyser wouldn't pick anything from ~-45 and above either so... weird ... anyway the lerp works with what ever number u want :D i just tested the audio thing in C3 volume can be heard at -100 also, so i guess do for fade in lerp(-infinity,0,dt) and for fade out lerp(0,-infinity,dt) that should fix it for sure ^_^ lmao...

  • I usually fade to -90 then stop the sound. That seems to work well.
