Sox and Avisynth+ r2772 issues [Archive]

Hi there,
I've been using sox for quite some time in the past, however it's been a while since the last time I used it.
Today I needed it in order to upmix the audio of a 6 seconds bumper to append it at the very beginning of a Dolby 5.1 movie.
As always, I tried to use UpSoundOnSound() however Avisynth+ crashes with an error.

This is what it happens when I try to use it with the simplest script possible:

ColorBars(1920, 1080, pixel_type="YV24")

This happens both on my Windows XP x86 machine and on my Windows 7 Enterprise x64 machine, both running the same version of Avisynth+ x86.
Is it only me that it's facing this problem or is it an Avisynth+ bug/incompatibility with sox?

I see lots of plugins, maybe try to rename existing plugin folder away and try with only necessary plugins.
Then I would try Assumefps().

Then I would try upmixing using internal AviSynth functions.

Or Jenyok's function itself: this is the old version, you may have to adapt "GetLeft.../GetRight" to channel numbers 1 and 2

# STEREO to 5.1 audio convertion
#
function UpSoundOnSound(clip clp)
{
# Sound On Sound Profile
# SOS approach Profile with 20ms delay and some attenuation on surround

a = KillVideo(clp)
back = a.soxfilter("filter 100-7000")
fl = a.GetLeftChannel()
fr = a.GetRightChannel()
cc = mixaudio(a.GetRightChannel(), a.GetLeftChannel(), 0.5, 0.5)
lfe = ConvertToMono(a).SoxFilter("lowpass 120", "vol -0.5")
sl = mixaudio(back.GetLeftChannel(), back.GetRightChannel(), 0.668, -0.668)
sr = mixaudio(back.GetRightChannel(), back.GetLeftChannel(), 0.668, -0.668)
sl = DelayAudio(sl, 0.02)
sr = DelayAudio(sr, 0.02)

return (MergeChannels(fl, fr, cc, lfe, sl, sr))
}

I found only an old stereo4.avsi where the location of sox is hardcoded "C:\PROGRAM FILES\AVISYNTH 2.5\PLUGINS\SOXFILTER_11\soxfilter.dll")
and I don't have that folder anymore since I am switching AviSynth versions anyway with Groucho's tool.

...and I don't have that folder anymore...

SoxFilter can be downloaded here: https://forum.doom9.org/showthread.php?p=761154#post761154

EDIT:
Seems than SoxFilter don't work with Avs+, this script:
ColorBars(1920, 1080, pixel_type="YV24").Assumefps(25).Trim(0,9999)
a = KillVideo()
fl = a.GetLeftChannel()
fr = a.GetRightChannel()
cc = mixaudio(fl, fr, 0.5, 0.5)
lfe = ConvertToMono(a).SoxFilter("lowpass 120", "vol -0.5")
back = a.SoxFilter("filter 100-7000")
#lfe = ConvertToMono(a).Amplify(0.5)
#back = a.Amplify(0.7)
sl = mixaudio(back.GetLeftChannel(), back.GetRightChannel(), 0.668, -0.668)
sr = mixaudio(back.GetRightChannel(), back.GetLeftChannel(), 0.668, -0.668)
sl = DelayAudio(sl, 0.02)
sr = DelayAudio(sr, 0.02)
MergeChannels(fl, fr, cc, lfe, sl, sr)
SoundOut()
Crash with Avs+ 32bits but work with AviSynth 2.60.
Without SoxFilter (the commented lines) work fine.

Has there been any progress on getting SoxFilter working in the new Avisynth+?
'cause in the current version of Avisynth+ it's still broken.
I have to upmix some stuff that I have to send to a cinema and I don't really feel like using ConverttoMono().Amplify() for LFE, 'cause that would honestly create A LOT of basses.

As result, I've temporarily killed LFE.
It's better not to send anything than to send non low pass filtered frequencies...

a = last
fl = a.GetLeftChannel()
fr = a.GetRightChannel()
cc = mixaudio(fl, fr, 0.5, 0.5)
lfe = ConvertToMono(a).Normalize(0.00)
back = a.Amplify(0.7)
sl = mixaudio(back.GetLeftChannel(), back.GetRightChannel(), 0.668, -0.668)
sr = mixaudio(back.GetRightChannel(), back.GetLeftChannel(), 0.668, -0.668)
sl = DelayAudio(sl, 0.02)
sr = DelayAudio(sr, 0.02)
MergeChannels(fl, fr, cc, lfe, sl, sr)

Have you tried the x64 version: https://forum.doom9.org/showthread.php?t=181566 ? tebasuna51 says it works.

With soxfilter.dll v64 bits the same error hapen:

SoxFilter: (filter) Could not restart filter:

filter: Unable to make high filter

But there are a workaround. The original code in function:

back = a.soxfilter("filter 100-7000")
fl = a.GetLeftChannel()
fr = a.GetRightChannel()
cc = mixaudio(a.GetRightChannel(), a.GetLeftChannel(), 0.5, 0.5)
lfe = ConvertToMono(a).SoxFilter("lowpass 120", "vol -0.5")
sl = mixaudio(back.GetLeftChannel(), back.GetRightChannel(), 0.668, -0.668)
sr = mixaudio(back.GetRightChannel(), back.GetLeftChannel(), 0.668, -0.668)
sl = DelayAudio(sl, 0.02)
sr = DelayAudio(sr, 0.02)

return (MergeChannels(fl, fr, cc, lfe, sl, sr))

replaced with:
back = a#.soxfilter("filter 100-7000")
fl = a.GetLeftChannel()
fr = a.GetRightChannel()
cc = mixaudio(a.GetRightChannel(), a.GetLeftChannel(), 0.5, 0.5)
lfe = ConvertToMono(a).SoxFilter("lowpass 120", "vol -0.5")
sl = mixaudio(back.GetLeftChannel(), back.GetRightChannel(), 0.668, -0.668)
sr = mixaudio(back.GetRightChannel(), back.GetLeftChannel(), 0.668, -0.668)
sl = DelayAudio(sl, 0.02).soxfilter("filter 100-7000")
sr = DelayAudio(sr, 0.02).soxfilter("filter 100-7000")

return (MergeChannels(fl, fr, cc, lfe, sl, sr))
work fine.

Seems the sox high filter does not support multichannel audio (with avs+) maybe because the know issue (https://forum.doom9.org/showthread.php?p=758905#post758905):
* If one filter doesn't support multichannel audio the entire chain is converted to mono filters, this might affect some filters like "earwax". Use multiple filter instaces instead.

Of course I recommend send a empty lfe, for instance:

lfe = fl.Amplify(0.0)

Also never use Normalize() with sox filters, it need 2 pass and restart the filters can cause troubles.

Use the ffmpeg filters instead avisynth for the upmix. I can recommed:

ffmpeg.exe" -i "input 2.0" -af "surround=lfe_out=0" -acodec pcm_f32le "output 5.1"

Ahh thanks for the info. I saw in the x64 thread that you linked back to this thread and said it worked with the sample here so I assumed it was fine.
