[Fuse] Suck Less Audio File Modifier

[SecondMan]

I do with the picture, it works, with video no

That seems very odd indeed.

When I asked to post your setup, I didn't mean screenshots. In Fusion you can copy nodes from the Flow View and paste them in a text editor, or in a forum.

When you do, post them inbetween [code][/code] tags. Or you can look for Forum Utilities in Reactor to make posting even simpler.

Is there any way to make the modifier smoother/less sensitive?

There sure is. You can chain Modifiers together in Fusion. So once you have your initial (too sharp) motion set up, right click on the parameter again and insert another Modifier, like a filter:



What this does essentially is Suck Less Audio -> Filter -> Parameter. Adjust to your liking and you're all set!

Insert another Modifier, like a filter:

In all these years I've never known about this specific filter. It had a difficult name, so I didn't bother.
This is great, Pieter! Thanks!

Added in 7 minutes 36 seconds:
Ehhh... wait a minute. This filter doesn't show up in my modifiers menu. Do I need to install something for that?

[SecondMan]

Do I need to install something for that?

Ohhh yes indeed. They used to ship with Fusion, so I didn't think of that.

Someone should pack those up for Reactor...

@DimaS I will need the .wav file as well, please.

Oh, I see what's wrong. In Suck Less Audio, set your Sample Start Frame to your comp's Render Start Time. That would be 866 according to your screenshot. You've simply run out of sample

Thank you so much

Well, this is great. I will read the entire thread later this evening, but I wonder if the topic of Davinci Resolve comes up, so that we can pipe the audio from the mixer/bus, vs. a dedicated wav file on the hard drive?

In DaVinci Resolve this would allow me to drop the fusion comp onto the timeline, and link to a mixer/bus. the visual modification in the comp would simply monitor the bus and use this... for one thing the comp would never be out of sync with the audio coming from the timeline...

[SecondMan]

so that we can pipe the audio from the mixer/bus, vs. a dedicated wav file on the hard drive?

No, that's not what the Fuse does at all. It's a WAV reader, plain and simple.

A really great fuse. I did the great tutorial from A Blackbird called Sue and of course caught a PCM file that didn't work. The reason for this is the junk chunk (great tongue twister) in the header. This is also generated by the DR renderer. With a few small changes you can make this possible.

First of all, the header must be larger and adjusted. Then the start of the sample data can be found (data_pos).

Code: [Select all] [Expand/Collapse] [Download] (Untitled.lua)

1. .
2. .
3.     -- create a table containing the header of the file. This will then be used to get file type, sample rate etc. In wave file the header is stored in the first 44 bytes of the file.
4.     local header = getHeader(filedata, 104) -- Org 44 - Junk 104
5.    
6.     --get some vital information out of the header, to do some form of file format checking
7.     if header[3] == header[4] and header[17] == "16" then
8.         format = "WAV"
9.    
10.         bitrate = sampleRead(filedata, 26, 25, 0)
11.         channels = header[23]
12.     else
13.         -- Suche data      
14.         data_pos = string.find(filedata, "data")
15.         data_pos = data_pos + 8                   -- 4 bytes "data" und 4 byte Size
16.        
17.         if header[13] == "74" and data_pos ~= nil then
18.             -- Junk-Format
19.             format = "WAV"
20.             bitrate = sampleRead(filedata, 62, 61, 0)
21.             channels = header[59]
22.            
23.             print ("########JUNK#########")        
24.         else
25.             print ("Unsupported file type.\nPlease only load of type WAV (Microsoft) signed 16-bit PCM.")
26.             return nil
27.         end
28.     end
29. .
30. .

Then adjust the generation of the sample data

Code: [Select all] [Expand/Collapse] [Download] (Untitled.lua)

1. .
2. .
3.     -- create sampledata table for MS WAV (little endian)
4.     if format == "WAV" then
5.         for pos = (data_pos+sampleoffset)+((currenttime-startframe)*spf*samplestep), ((data_pos+sampleoffset)+((currenttime-startframe)+1)*spf*samplestep)-samplestep, samplestep*proxy do
6.             if pos > data_pos-1 then
7.                
8.                 local deb_werte = {}
9. .
10. .

And finally the change for the ModifyChanged

Code: [Select all] [Expand/Collapse] [Download] (Untitled.lua)

1. .
2. .
3.     if inp == InFile then  
4.             local filedata = readAll(param.Value)
5.             if not filedata then
6.                 return
7.             else
8.                 local header = getHeader(filedata, 104)       -- Anpassen
9.                 if header[13] == "74" then
10.                     temp_channel = header[59]                 -- Junk-Format
11.                 else
12.                     temp_channel = header[23]                 -- Wave Format
13.                 end    
14.                    
15.                 if temp_channel == "2" then
16. .
17. .

I haven't tested it extensively, but it works fine.

[SecondMan]

Oh nice, thanks for the pointers! I haven't looked at that code in a very long time. Would you be willing to send me your working version?

Welcome to WSL, by the way. Great first post
