Audio External FFT issue with R6

Post by Foxid »

Hello,
I've recently purchase the new resolume arena 6 and I'm trying to get my previous configuration (of R5) working.
I've got an issue with the external audio. I configurate my mic input as "Audio Input Device" and set the "left" channel in the External Audio set up. (Btw why I can't select "Left&Right" like in R5 ?)

And the problem is, even with my fft gain at +24dB, my signal as a shitty dynamic range.
The bass are quit good but I've got no middle or high signal (It barely crank up to ~5%)
I tried my configuration with the same song in R5 and it's good, it also work well in Adobe Audition. I've got a nice waveform, with middle and high, the bass is not loud all the time like in R6.

Do you know what's wrong with the R6 ? Or if it's me and my configuration ?

Thanks.

Could you tell us more about your configuration, system specs, which Resolume 6 version are you using etc?

Can you confirm that you've got full dynamic range in your external FFT animation settings?

This is not about what range I'm choosing for my effect to react. Before selecting the part of the spectre that I want to make my effect to react, I'm trying to get a audio input with all the spectre available in my original song. The easier way to explain is to show you.

This is what I've got with a song in R6 (built in mic set as input device, channel Left) Gain at max level

And the same part of the song in R5 (built in mic set as input device, channel Left&Right) Gain at max level

Maybe it's only a matter of gain ?

The gain is not turned up in your R6 screenshot.

Oh snap ! due to its grey tint and since I'm using the main "FFT Gain" knob I tought it was locked. I haven't tried to turn it... Sorry for my mistake.
Plus I've test with a external mic and it's reduce the amount of base (probably the fan in my laptop with the built in mic).

I still have much more bass than middle and high but with the main fft gain plus the gain per effect I can make it works like I want. Thanks :)

Just increase your range.

If I increase the range it will result as an effect who will react to all the spectre, and not just a part of it.
In my example my range was on the bass but I also want effects that react to the high or the medium.

My issue was to get enough informations in the input signal, to be able to select the range that fit the effect.
Anyway, I've make it works by combining the main fft gain and the gain on each effect.

A better solution will be to get an equalizer before the audio signal get into resolume.

Up today I have the exact same problem and I dont know how to solve it.
To bring an graphic EQ before my interface isnt the right way for me.

In R5 the signal was defnitely much better.
In R6 its like an High Cut Filter at about 630Hz.

I only become a good mid/high signal when i really really amplify a lot.

Is there any solution?

Looks like in R5 the response curve of the FFT spectrum was weighted towards the highs.
In R6 it's flat, which is the accurate representation of the spectrum. You can check that by sending a white noise signal to your FFT input.
