Music Media Helper (Tools for Multichannel Audio & Music Videos)

[SeeMoreDigital]

Yes. M4A is simply a container.

Indeed... And is it re-muxed from .mkv to .mp4/.m4a using FFmpeg or a different .mp4 muxer?

 

[HomerJAU]

MMH uses ffmpeg

I use MMH Extract Audio from MKV feature. Yes, FFmpeg.

Version 8.0.9 Beta 4 (November 10 2024) - changelog below is all changes since official MMH 8.0.8 release
-------------
New:
Channel Layout Remix tool: User Defined Channel mappings can now be saved and restored - new
Channel Layout Remix tool: Added support for .w64 files
*Join and Split files tool: Added support for .w64 files
*Join and Split files tool: A Cue file is now auto created on completion of file join ('Merge' command).

Fixes:
*Join and Split files tool: Tags from .m4a files were not read into grid when adding files - fixed
*Join and Split files tool: Cue files did not contain correct media file name - fixed (path was included)

Changes:
Multiple tools: Add new auto file name preference to support Track Number separator: ' - ' Example: '01 - Title.flac' (default remains '. ' '01. Title.flac')
Channel Layout Remix tool: Added new User Defined '4.0.4' layout for Output only - new
Channel Layout Remix tool: Added new User Defined 'Quad(side)' layout for Output only - new
Channel Layout Remix tool: Add support for copying ffmpeg command line (users must still select Input and Output layouts but no need to remap - new
MMH Atmos Helper: Decoder added support for a user defined DRP install folder (MMH looks for default install location, if not there new button allows selection)
*Join and Split files tool: General code cleanup and maintenance
*Updated PDF docs (to reflect recent updates in Preferences dialog, Channel Layout Remix tool, Join and Split files tool and Launcher dialog

Just a casual reminder... what HomerJAU is doing for us all here is legendary and, dare I say, life changing for our enjoyment of multi channel music. Cheers!

I haven't kept up for awhile, so sorry if its answered; I did scan the latest pdf but didn't see an answer.

I know that MMH can fix inversions and delays, but can it detect them in multichannel files?

No detection. Only manual fixing. I’m not sure how auto detection could be done.

 

[ssully]

Me neither. Of the two, I'd think 100% phase inversion of a track versus others would be easier to detect. But don't ask me how.

...phase inversion...

You mean *polarity inversion?

Apologies if I missed this but when decoding Atmos, I'd previously compensate for the DialNorm values manually (usually by adding 13dB gain, depending on the DN value).

Doing this with the latest Atmos helper release seems to clip the files. Am I right in thinking MMH now compensates for DN values automatically?

A change in 8.0.6 (November 3):

Changes:
MMH Atmos Helper: Decoder: Decoding EAC3 Atmos (Dolby Digital Plus) now has louder decodes (previous DRP command line argument was ignored)

Thanks!
Is the volume boost tied to the DN values? I tried decoding two files, one with DN -18 and one -31, and neither seemed louder than the other after decode, which seems to point that way?

 

[HomerJAU]

The 8.0.6 release changed a decoder setting from one that suppressed Dialnorm (that actually did nothing) to a new setting that changes Dialnorm to 0 during the decode (to make output louder). A fellow QQ member did some detailed comparisons and the new setting makes the EAC3 decodes about 10db louder. My tests shows the increased volume varied by encoded DialNorm setting. (Measured not by listening).

I don’t have Dolby docs on these settings, this MMH Atmos decoding change is based on experimental results. The previous Dialnorm suppression option for EAC3 did not work (probably a bug in DRP). Edited for clarity.

If you run decodes using current MMH Atmos Helper vs MMH 8.0.5 or earlier you can compare the results yourself.

Great, thanks!
Compensating for DialNorm automatically is a big time saver.

Does this affect if we are extracting 24/48 TrueHD to wav, or just EAC3?

 

[HomerJAU]

Just decoding EAC3. And only if you don’t apply any Gain options during the MMH Helper decode (those Gain options apply gain to the decoded wav immediately after the DRP decode).
