i need PA delay line , adjustable

[tonitonitoni]

i have been reading , and i think that this should be fairly simple using lets say behringer uca202 for adc and dac ,and laptop for memory and control, only thing is i cant find any software for doing this ,what can i do ,its cheap diy PA so i want this to be cheap solution too


basicaly i will conect fill speakers at distance around 20 meters , could all pass filter work in this case? becouse i need adjustable

thank you for help.

Well if you have a basic PC left you can attach it to Behringer/speakers but controll it with your laptop from your 20 meter via RemoteDesktopProtocol or any soft doing this job !

Free if you have the PC already ! via wifi or with a 20 meter category 5 wire and a basic switch/router (20 euros)

no problem with getting signal 20 meters away, have both balanced and regular option. have problem of how to get signal in computer memory wait for adjusted ammount of time, then play it back, only need pc software (what works on windows) that can do that. i cant find if that kind of software exist, only found some software with minimum delay of 0.1s what is too much for 20 meters.

Hello,
I think foobar has a plugin in the DSP manager that allows for this 'Channel Mixer' in the Delays tab. You can specify for 5.1 sources too iirc.
If you need a pre-configured foobar2000 in useable state let me know and I can upload my install

 

[tonitonitoni]

wait what, using foobar for this is possible ?? woow, thank you i will try it myself and when i fail i will contact for help , only need stereo input and output but if there is 5.1 option that will be useful one day too, thank you very very much

yep cant find that addon with that same window,please send ,thank you....EDIT , no need i found it was third party addon,thank you very much EDIT2, it works fine but cant use it as realtime processor of input sound

Try foo_record with it.

 

[tonitonitoni]

hm it works but it seems foo record has its own delay of 2 seconds

Hi,
Uh foobar has a buffer, default its set high at around 1500ms IIRC. Try lowering that.

 

[tonitonitoni]

will try to use free vst, with some delay plugins which have adjustable 0-500msec delay, with dry signal turned off i think it should work with asio drivers, if not then i will try foobar with asio and foo record. will post here later if i find solution

DaanSystems - Radiodelay
That utility has 100ms minimum setting - try contacting developer perhaps can reduce it.
You may need a virtual cable, virtual jack looks good - not tried it.

 

[tonitonitoni]

there is no reliable way of doing this with pc. all programs made for this are completly useless as that programs just add more software buffers, maybe it is useful in minimum 200ms delay.

Hi. I found more possible ways to try:

#1 Voicemeter, in the settings you can specify delay in ms. It accepts hardware line-level inputs > delay > output and operates at Kernel / WASAPI Level to minimize extra OS delays/interference. This is the better free solution.

#2 matrix_mixer, a directshow filter (.ax) filter.
You need a directshow based program which accepts line-into with this method.
Try this plugin for WMP in conjunction to allow line-in recording.
MatrixMixer has control panel in start menu after install..
Options to look for are delay on second tab and 'Autoload with directshow' on the third tab. Delay can even be specified in meters. Not sure if direct show adds a delay, it probably does. Option #1 is better option.
