BeHappy - AviSynth based audio transcoding tool (UPD 19-07-2006) - Page 52

No problem, it's not urgent or anything.

But uh,...another question:
I wanted to see if the foo_input_avs-issues I face on my WinXP machine, would also bring me headaches on a Win7 laptop (of a friend), but I just can't get BassAudio to work.

Code:

LoadPlugin: unable to load: "<path>\BassAudio.dll", error=0x7e

Now, the only related post I could find it this one:

make sure you have the Visual Studio 2010 runtime installed, as the plugin requires it.

Installing that one, nor the 1st servicepack made a difference. .NET Framework 2, 3 and 3.5 are not compatible with Win7, but installing .NET Framework 4 wasn't rewarding either.
Do you have any idea what I'm doing wrong and how to get BassAudio.dll working on Win7?

tebasuna51 · 12th August 2012, 19:10

BassAudio.dll (v2.4 2008) was compiled with Visual C++ Express 2005.

I make a new compile with Visual C++ Express 2010, with a more recent version of AviSynth.h and the last Bass.h (with Bass.dll 2.4.9).
Work for me (XP SP3) with Bass.dll 2.4.8 but still not work with 2.4.9

I can't test W 7. Please see if there are any difference with previous version.

Thanks. Once I get a hold of my friend's laptop I'll let you know.

Reino · 18th August 2012, 16:49

Okay, earlier this week I've used a family member's Win7 laptop and everything went fine with MPC-HC and Foobar.
Yesterday I had the chance to test BassAudio on my friends Win7 laptop again, but surprisingly everything went fine too. I guess I made some mistakes last time. The old BassAudio.dll as well as the new one worked fine. After that I even quickly installed Avisynth and Foobar on my mother's old WinXP laptop, but even that one could play it all.
Now that was really frustrating! Eventually I even monitored Foobar's every single move on my computer with Sysinternals Process Monitor, in the hope I could find an answer for the issue I faced. But then I suddenly realized; I had been using Foobar 1.1.14-b3 to test BassAudio on the other computers while my own computer still had 1.1.10 installed. And what'd you know, after updating to 1.1.14 yesterday I could suddenly open all bass_xx.dll audio formats in Foobar! Not my computer, not BassAudio and neither foo_input_avs is to blame, but me still using an old version of Foobar...

Everything is fine now. Sorry for the trouble, tebasuna51.

Compression curves based in Anex C from Dolby Digital Professional Encoding Guidelines. There are a link for this document and graphs in:
http://forum.doom9.org/showthread.php?t=56020

This is a test release for discussion about the following problems:

1) The DSP function, outside the ac3 decoder, can't know the original ac3 Dialog Normalization and DRC method, then must be supplied by the user.
The DRC method can be selected in DSP configure, but the DialNorm can be set with:
- Another DSP multioption (31) to use before DynRanComp.
- With the 'Tweak' Amplify, but don't work with negative values (? to Dimzon).
- Editing DynRanComp.extension before run BeHappy. Method selected in this test release.

2) The Normalize() function don't work after Sox compand, maybe because:
"compand is very hard to control, and doesn't support restarts (crash)"
(in "Sox Audio Effect Filter for AviSynth" doc.)
Then maybe we need another set of 'normalized' curves to avoid the low volume problem.

3) The compand function don't work fine with segments 20:1.
For segment (-21,-21)-(0,-20) I obtain a output (-21,-21)-(0,-18)

4) The compand parameters (attack1,decay1,...,delay) may need optimization.

Sorry to quote this whole thing, from a long time ago. But I had a look at the Sox compand function for your Film Standard DRC, and it seems to me that it doesn't produce the expected DRC curve from Dolby. I did a plot of it with gnuplot, from Sox.

I tried to modify it to make it look like the expected curve, and this one did seemed to do the trick.

Film Standard:

compand 0.1,0.3 -90,-84,-43,-37,-31,-31,-26,-26,-16,-21,0,-20.25 0 0 0.1

I don't know why Dolby mentions the final cut range to go from 16dB... to +4dB in their documents, since 0 dBFS is our limit to work with. Also, the dial norm of -31dB doesn't seem to be symmetric in the the null band for this DRC profile, while for Film Light it is. That's something I also don't understand.

Maybe you have a comment on this, after all these years?

We need remain with 2.4.8 version.

What about BASS 2.4.10?

Could you let the next BassAudio version accept original BASS add-on filenames? At the moment it seems BassAudio only accepts BASS add-ons with an underscore in their filename (bass_xxx.dll, like the 3th-party add-ons). BASS' own add-ons; basswma, basscd, bassflac, basswv and bassopus, don't have an underscore in their original filename. You'd have to add one manualy for BassAudio to work.

Where could I find algorithm "A real time audio upmixing method from stereo to 7.1 channel audio" ?
Discription of this algorithm.

Thanks.

Maybe in next version. But is really easy, or not?

Sorry I don't know.
Maybe is better use receivers DSP's to do this job.

One more question to you.
.
What string parameters in SoxFilter(...) function for AVISynth could I use to achive following result "Concert Hall Light, No combine sourse Left аnd Right" ?
.
Thanks.
.

tebasuna51 · 8th April 2013, 12:58

What is "Concert Hall Light, No combine sourse Left аnd Right"?
A DSP function of a receiver?

Sorry but I can't help you with your questions.

@ tebasuna51:

"Concert Hall" is probably a reverb model. There is a brief explanation in a webpage about a Lexicon reverb filter. I don't know if there is any kind of parametrical implementation; modern reverb filters will probably use "convolution" impulse response models (applying the recorded echo of a sharp impulse in a real sample room to the input sound).

See my opinion about 2.0 -> 5.1 conversions in this post.

One of the greatest tool ever..

Any chance of the opus support?

LigH · 24th May 2013, 07:26

Yes, there is an Opus plugin supported in BASS. Getting it supported in the AviSynth BassAudio plugin has been discussed already, I am just not sure if here or in the HydrogenAudio forum...

tebasuna51 · 24th May 2013, 15:55

Yes, to decode a opus file you need download bassopus.dll from http://www.un4seen.com/ , rename it to bass_opus.dll and put it with BassAudio.dll and Bass.dll suplied with BeHappy at the default AviSynth-plugin folder.

Behappy appears unable to downmix AC-3 4.0 to 2.0 with NicAC3Source(). It attempts to downmix it as if were a six-channel mix and uses GetChannel() on non-existent channels.

tebasuna51 · 8th November 2013, 00:26

BeHappy have only a few pre-definned downmix functions, see DownMix.extension.

The users can modify DownMix.extension or load the .avs than make the correct downmix.

Reino Registered User Join Date: Nov 2005 Posts: 693	Okay, earlier this week I've used a family member's Win7 laptop and everything went fine with MPC-HC and Foobar. Yesterday I had the chance to test BassAudio on my friends Win7 laptop again, but surprisingly everything went fine too. I guess I made some mistakes last time. The old BassAudio.dll as well as the new one worked fine. After that I even quickly installed Avisynth and Foobar on my mother's old WinXP laptop, but even that one could play it all. Now that was really frustrating! Eventually I even monitored Foobar's every single move on my computer with Sysinternals Process Monitor, in the hope I could find an answer for the issue I faced. But then I suddenly realized; I had been using Foobar 1.1.14-b3 to test BassAudio on the other computers while my own computer still had 1.1.10 installed. And what'd you know, after updating to 1.1.14 yesterday I could suddenly open all bass_xx.dll audio formats in Foobar! Not my computer, not BassAudio and neither foo_input_avs is to blame, but me still using an old version of Foobar... Everything is fine now. Sorry for the trouble, tebasuna51. __________________ My hobby website

Thanks. . __________________ Warm and fuzzy (white and fluffy)

LigH German doom9/Gleitz SuMo Join Date: Oct 2001 Location: Germany, rural Altmark Posts: 6,784	@ tebasuna51: "Concert Hall" is probably a reverb model. There is a brief explanation in a webpage about a Lexicon reverb filter. I don't know if there is any kind of parametrical implementation; modern reverb filters will probably use "convolution" impulse response models (applying the recorded echo of a sharp impulse in a real sample room to the input sound). __________________ New German Gleitz board MediaFire: x264 \| x265 \| VPx \| AOM \| Xvid Last edited by LigH; 9th April 2013 at 07:53.
