AC3Filter / Re: AC3 Filter does not upmix 2 ch Wave Pack ".wv" format to 5.1
« Last post by eascart on April 20, 2017, 01:12:22 AM »
What's the use of a forum where nobody replies? I realized that mono songs turned into stereo have two channels exactly the same, so upmixing using matrix 1 and -1 results in 0, so no surround exists. Saddly Ac3Filter does not upmix Monkey's Audio too! Yes, a lossless format like FLAC itself. And there's no equal channel but still no surround. I wish I could solve the problem and contribute with this forum, but I don't have the knowledge, sorry. I holpe someday someone could help me and maybe make some changes in future AC3FILTER versions in order to to correct this issue. I have AIMP to play these songs in 6 channels, but I really prefere using MPC-HC.

AC3filter Properties has changed to Gibberish in any language... Any suggestions?


Tried to uninstall & install AC3filter other versions, Change Windows language settings, but nothing so far...

Well, it happened right after some Windows update, so all good after re-installing Windows...

AC3Filter / Missing SR and SL Channels Upmixing 2 channel mono songs
« Last post by eascart on December 27, 2016, 12:23:47 AM »
I noticed that AC3Filter creates SR and SL Channels in auto matrix by adding 0.5 and -0.5 from L/R channels so in case of original mono files recorded as stereo (2 channels mono) the two waves are the same as the result returns zero. Is there any workaround insted of turning off auto matrix and setting both values positive? Could the creatores of AC3Filter make it recognize the null channels correcting and creating the rear channels? One soluction I tried was using Musereo to create a fake stereo so L and R would become different waves, but I want to preserve the original recording sound.

Здравствуйте, наконец я смог запустить на своей машине AC3Фильтр с ПотПлеером. ОС - Вин 7/64 бит.
AC3Фильтр настроен на передачу многоканального звука на SPDIF выход карты точнее на TOSlink output (карта ESI Julia).

Столкнулся со следующими проблемами:
1. во время проигрывания фильма во вкладке Каналы АС3Фильтра НЕ отображаются данные об уровнях громкости у каналов.
2. настройка уровней громкости у каналов в тойже вкладке не дает никакого эффекта.

Подскажите что нужно сделать чтобы суметь настраивать каналы - нужно увеличить громкость центрального канала.

AC3Filter / AC3 Filter does not upmix 2 ch Wave Pack ".wv" format to 5.1
« Last post by eascart on August 12, 2016, 09:39:13 PM »
Got me a compressed wave pack format audio cd and AC3 Filter does not upmix to 5.1, center channel and surround are missing. Audio is lossless 2 channel stereo 44.100 16 bit. I have seen this with some mono files but never with stereo ones. Every other formats played upmixed to 5.1. Maybe converting to another format should solve the problem but I'd like to play as it is. Thanks for any help. Sorry about my english, actually I speak brazilian portuguese.

AC3Filter / Channels mixed up.
« Last post by Fred2486 on July 10, 2016, 12:06:31 PM »
Hello
Could someone help me please?

I'm trying to get 5.1 sound on my home cinema from PC through SPDIF form my sound card, to do so I use Virtual cable to send sound to AC3filter so i can encode it and send it to my Xonar U7.
It works i get better sound with better bass and all channels work BUT then i downloaded few surrond tests ( http://www.demo-world.eu/dolby-dts-thx-wmv-distributor-trailers-sd/ ) and I have noticed some issues:

When center plays, left and right plays too.
When left surround (back) plays, left plays loud too and surround only quietly.
When right surround (back) plays, right plays loud too and surround only quietly.
And the subwoofer doesn't play at all (only in the tests).

I'm not sure where the problem is, I tried a few things like tunning the mixing matrix or trying the amplification, didn't help at all (maybe I have done it wrong?)

Setup:
Home cinema: Samsung HT-C5550 + wireless transmitter for surround speakers.
Sound card: Asus Xonar U7 (external via USB)
Virtual Cable 4.13
AC3 filter 2.6.0b
GrapStudio 0.3.2.0b
Windows 8.1 64bit

I'm attaching some screenshots of my settings. (On GDrive)

I'll be thankful for any advice  :)

AC3Filter / AC3Filter silent after 1 second when downsampling to 48K
« Last post by Dogmaps on March 07, 2016, 02:38:29 AM »
I’m using latest version of AC3Filter on Windows 10 with MPC-HC.  I’m using it to play DTS encoded audio on my hardware which only accepts AC3.  It works well when the input rate is 48K, but I have problems when the input rate is 96K and AC3Filter must downsample to 48K.  When input rate is 96K, it plays audio sounding good for 1 second and then becomes silent.  I can see from AC3Filter GUI it continues to process audio after silence, but I hear nothing.  If I pause MPC and play again, I hear output again for 1 second, and then it becomes silent again.

I’ve tried changing different settings of AC3Filter, but I can’t get it to work when input rate is 96K.

Does anyone know what the problem could be, or how I could solve it?

Thanks much!
