M4A problem

----------------------------------------------------------------------------------------------
Converting from m4a to mp3 causes major distortion.

Has been happening in all builds of v.12
Finally got good samples to offer.

Original M4A
Distorted MP3

Tools>Options>Encoding>Encoding for File Conversion
Encoder = MP3 Encoder
Advanced:   Target Quality=Extreme or High


I can not reproduce this. Conversion works fine on my machine. It obviously did not work on your machine as your mp3 file linked above could not be played (not just distorted, but not playable).

What audio decoder filter do you use for m4a/aac?

Hmmm.... not entirely sure.  Tell me where I can see that info on my system and I'll check it out.

Play an m4a file. Look for entries like the following in the log file
(Filter [4aff47c]  'ffdshow Audio Decoder' is what is used on my machine).

Your log file is missing a lot of information. You should uninstall MC, and then reinstall it.

Ok, I uninstalled (left the registry entries and library).
Reinstalled.

The only unchecked box under logging is SDK.
Here's the results:

Doesn't seem to be anything new.
I then installed a newer version of ffdshow (2006-08-21).
Started MC and played the m4a file again.

Still not right. Please try uninstall, removing all registry entries (you can leave your library).

By the way, when you play a m4a file, do you see the spectrum analyzer in the "Current File" window or visualization?

Could it be that all logging types aren't enabled?  Or maybe it's using QT vs Direct Show?

Playback logging should have been enabled. zxsix said so:

Regardless whether using DirectShow or QT, the following line should have appeared in the log:

0005250: Playback: CPlaybackEngImpl::Play: Start

A while back some one had similar problem while trying to play dts files. Uninstall and reinstall solved it.

Yes, I see the spectrum analyzer in the playing status window.

Uninstalled and removed registry entries this time.

Here's the resulting log (no SDK):

I then had a look under Tools > Options > Playback > Directshow audio/video settings
M4A is in the "use directshow" column.
I highlighted it and clicked the Select Filters button.
Under the "currently selected" area, there was nothing showing.
I checked the box for ffdshow audio decoder.


Here's the log after that:

This is nutty.

You log file still is missing logging entries from PlaybackEng. But the playback behavior seems to be correct. What are the "File version" and "Date Created" of the file PlaybackEng.dll in MC12 installation folder?

Try regsiter that file (regsrv32 "C:\......\PlaybackEng.dll").

Does "Creative AC3 Source" filter handle AAC files? It does not sound right. Can you try "MP4 Source filter" instead?

This is nutty.

You log file still is missing logging entries from PlaybackEng. But the playback behavior seems to be correct. What are the "File version" and "Date Created" of the file PlaybackEng.dll in MC12 installation folder?
File version = 12.0.238.0
date created = today 7:56 am
date modified = 9/5/06 5:08 pm

Try regsiter that file (regsrv32 "C:\......\PlaybackEng.dll").
Done. Succeeded.

Does "Creative AC3 Source" filter handle AAC files? It does not sound right. Can you try "MP4 Source filter" instead?

Change made.

Here's the new log:

With MP4 Source filter selected, have you tried doing a conversion to mp3?

Here's the new log:

The new log still is not right.

Please do a search of your registry for "PlaybackEng", and make sure the following values are correct:

HKEY_CLASSES_ROOT\CLSID\{1751DFAB-3A82-4F5C-9CF7-AFB312B80268}\InprocServer32

HKEY_CLASSES_ROOT\CLSID\{59118AF7-8730-4EE9-BE0D-62CB454DD799}\InprocServer32

HKEY_CLASSES_ROOT\CLSID\{AEEB55EF-CC39-48F5-B4D1-A8DEDEAF7C7A}\InprocServer32

The "(Default)" value under these keys should be the path of PlaybackEng.dll in the MC12 install folder.

All present and accounted for.  Paths are correct.

When you're not using DirectShow filters to play M4A, MC will use the Quicktime engine.  In that case, no conversion would be possible.

You may have found a problem with a Directshow filter.

Would you like me to install a different version of ffdshow?

I couldn't say, but I'm just saying that you might take a closer look at the Directshow filters you're using.

Some progress.
I cleared all of the filters showing for .m4a in the directshow settings.
Played the track again.
Now I see the stuff you wanted in the log  :D

Finally, whew!

continued log....

Code: [Select]
0007031: Playback: DumpGraph: Start
0007031: Playback: DumpGraph: DumpGraph [6c4bdf0]
0007031: Playback: DumpGraph:     Filter [19cc1fc]  'MJ WaveBin Filter'
0007031: Playback: DumpGraph:           Pin [1a46db4]  'In' [Input]  Connected to pin [91c63c4]
0007031: Playback: DumpGraph:     Filter [15894484]  'ffdshow Audio Decoder'
0007031: Playback: DumpGraph:           Pin [91c63c4]  'Out' [Output]  Connected to pin [1a46db4]
0007031: Playback: DisplayTypeEx: Connection type  M type MEDIATYPE_Audio  S type MEDIASUBTYPE_IEEE_FLOAT

This may be the problem. I expect PCM format here for MEDIASUBTYPE, like this:

Code: [Select]
0060922: Playback: DumpGraph:     Filter [4ad147c]  'ffdshow Audio Decoder'
0060922: Playback: DumpGraph:           Pin [4ae6c24]  'Out' [Output]  Connected to pin [178a604]
0060922: Playback: DisplayTypeEx: Connection type  M type MEDIATYPE_Audio  S type MEDIASUBTYPE_PCM

Did you configure FFDShow decoder to do some other processing? If so, try turning them off.

I updated to a newer build of ffdshow (dated 9/1/06).
Plays and converts to mp3 properly without the distortion now.
I'll consider it case closed.  Thanks for the help.
If you'd like me to do any more testing on this let me know, otherwise I'll drop it.
Thanks for the troubleshooting.

I think I found a possible cause:

You may have checked "32 bit floating point" as supported output sample format on FFDShow audio decoder configuration.

When that is checked, the output is in MEDIASUBTYPE_IEEE_FLOAT format (if the sound card supports it, I guess). Our converter needs PCM format. So you need to make sure "32 bit floating point" is not checked. To access FFDShow configuration, you can either do a Start -> All Programs -> FFDShow -> Audio decoder configuration, or you can right-click the FFDShow icon in the notification tray when you play something, and choose "FFDShow audio decoder".

As an aside, I found out "32 bit integer" for output format is not good on my machine. Extremely distorted sound comes out of my speakers. So one should only check "16 bit integer" and "24 bit integer" normally (unless you know that your computer can handle other formats).

Upon reinstalling the newer version of ffdshow, I checked a box that said "reset all ffdshow settings". 
32-bit floating point is currently not checked.

Again, all seems to be working now since reinstalling ffdshow.
Don't know if it was a setting that was reset or a bug in that particular earlier build.  Either case, me happy!
