how do you handle your audio (soundmanager)?

MoKaLux

how are you all doing ?
I know the basics stuff for sound and sound channel but I wonder how to handle all the audio files?
https://wiki.gideros.rocks/index.php/Playing_Sound_and_Music

Is it good to declare every audio files in init or main?
Is it good to declare them as global?
...

I would also like to control the volume of all the sounds at once (via the option menu).

I have seen this class written in 2012!!! but I am not sure how to handle the management of audio files. Any tips for a sound manager please ?

Thanks!

to add to my question: I have different levels, in each level I have various monsters with various sound... how do I do?

EDIT: I ended up using the class in the previous post for the main scenes (menu, options, ...) and vanilla Sound and SoundChannel for the various monsters. It is a bit messy to be honest, I need to rethink how to organise my sounds

MoKaLux

is this the correct way to avoid "accumulating" sounds and having a crissy sound in the speakers?

self.sndnmeshoot = Sound.new("audio/sfx/sfx_wpn_laser4.wav") self.channel = self.sndplayer1hurt:play(0, false, true) self.channel2 = self.sndcoin:play(0, false, true) self.volume = 0.5 -- 0.01 ... local function dosound(xchannelid, xsound) if xchannelid == 1 then if not self.channel:isPlaying() then self.channel = xsound:play() end self.channel:setVolume(self.volume) elseif xchannelid == 2 then if not self.channel2:isPlaying() then self.channel2 = xsound:play() end self.channel2:setVolume(self.volume) end end ... --self.channel = self.sndplayer1hurt:play() dosound(1, self.sndplayer1hurt)

The problem with this approach is that only one sound will be played at a time by channels (or I can add more channels though)
Thank you

PS: bonus question, how do you initialize a channel without playing the sound, is self.channel2 = self.sndcoin:play(0, false, true) the only way (also channel:setPause(true)?

I am not sure this will still work, but if you want to take a chance I managed to put this thing together years ago from the credited sources, and it WAS working at the time hope this helps

cool thank you pie, I may use a mix of fadeIn, fadeOut for bgm but for short wav sounds like shoot, hurt, ... ? When multiple shooting sounds occur they "accumulate" and make my speakers scream

I think I need to arrange/distribute them in a couple of Channels to avoid the screamings.

@MoKaLux you can't stop the screaming if multiple audio sources overlap: their volume is never handled and can only increase until the screaming occurs.
The only way would be to have different sounds with different spans of the audio spectre, so that you won't ever overlap the same frequencies (ie the first sound happens between 80 and 500mhz, the second one spans through 501 to 750, the third from 751 to 1000.. but you can't have the same sound played twice because the problem would rise again as soon as the same frequencies overlap and reach the speaker limit).

But you can trick the listener as you can read here:
https://www.reddit.com/r/gamedev/comments/dq4k3q/how_do_you_handle_a_bunch_of_sound_effects/

A slight mod to the provided audio class (assuming it still works) should make it able to check if the sound is already playing and restart it, or do it only if there are already (guessing) 2 instances of the same sfx, or it could lower each sfx volume for the time needed (but I think this option would sound awkward )
