There seems to be a weird little bug in the latest Winamp plug-ins, concerning filenames.

I noticed that if an MPC file doesn't have any tags, the plugin tries to fill in the fields by itself. It can 'guess' the album name/year, song artist/title and number from the foldername and filename.

Works pretty good, but today i played an album where the songs had these names:

01 Notorious B.I.G. - Notorious Thugs.mpc
02 Notorious B.I.G. - Miss U.mpc
03 Notorious B.I.G. - Another.mpc
...

The plugin failed in retrieving the tag info, displaying this playlist:

1. Mpc 2 - - Notorious Thugs
2. Mpc 2 - - Miss U
3. Mpc 2 - - Another


In the "Info" tab of Winamp, it was all mixed up, for instance: Track #: "03 Notorious B.I.G", Title: "- Another", Artist: "Mpc 2".

I reckon this is because of the extra dots in the filename... but what can i do, that's what the guy is (was) called.

Thanks for reporting, I had included one naming scheme in the middle of the old ones and that caused the problem. It should be fixed in this version.

[gdougherty]

Is it possible to directly convert older files into the new version to pick up the space savings?

Ah yes, the bug is fixed. Thanks!

Chemical Brothers "Dig Your Own Hole" - Electronica, Trip-Hop:

mppenc 1.02 --xtreme (no tweaks): 86.0 MB; 190 kbps ave
mppenc 1.04 --xtreme (no tweaks): 74.8 MB; 164 kbps ave

What have you done, Frank, to reduce the encoded file sizes?
Great work.

Addendum:

Richard Thompson "Mock Tudor" - British Folk/Rock:

mppenc 1.02 --xtreme (no tweaks): 80.3 MB; 204 kbps ave
mppenc 1.04 --xtreme (no tweaks): 78.3 MB; 198 kbps ave

Apparently the aggressive bitrate savings are to be had in electronica, not folk/rock.

[macdaddy]

My mileage is a little less impressive, but I use a command-line with more overkill:

--insane --nmt 16 --tmn 32 --verbose --verbose

I encoded a live show that was an hour duration. With 1.02, the file size was 136MB; with 1.04 the file size is 134MB. It would appear then, that the new encoder makes more of a difference shaving the bitrate with less aggressive settings...

The sound quality is superb, as always. Case, the 24-bit decoder works fine, too. Many thanks.

Now thats a significant reduction. These bitrates (164) more or less fall into the 'standard' category. Now if there's no difference in sound quality, thats a really good achievement. But is so ?

Or is Frank trying to prove that the 'standard' bitrates are indeed 'no different' than the 'xtreme' bitrates as far as quality is concerned ?

Anyone checked out the bitrate differences for 'standard' ?

Not a bad idea of Garf's!

Trouble is in this instance, the --xtreme setting --verbose comments confirm that --xtreme is still nmt 8, tmn 20, and other parameters appear unchanged: so what has happened?

Verbose was fux0red to give you the impression it's encoding with those parameters.

Another electronic album... not quite as much of a savings either so the bit reduction here don't seem to quite be universal, but it's still not bad.

I haven't really had a chance to scrutinze the quality or encode much else though so I'll have to give that a shot and see how it works out.

It can not only do MP3 analyzing, but also basic MPC analyzing. It shows the average bitrate for a folder in the lower left corner of it's window.

Invalid MP3 framesizes... list.exe needs some accuracy tunings.

[Gecko]

Is mppenc 1.04 based on one of the four versions of mppenc, that were posted recently?

Just for the record, I encoded two trance compilations (eye trance 3 and 4 without the turntablemix) at --standard --nmt 8.
v1.02: 414mb
v1.04: 383mb
That's a saving of 31mb or ~7.5%. If quality doesn't suffer, this is quite impressive imo.

I'm still a little sceptical though, but I guess I've been brainwashed to just compare bitrates without actually listening. Everything sounds ok to me, but then again, I'm not the one to ask these things.

This is the exact bitrate of the file.

Filesize * 8 bit/byte / playtime

The program shows the really needed bitrate.
A MP3 stream with 3 MByte ID3V2 tags can have
700...800 kbps (it is not difficult to find such
nonsense in the internet, 15 MP3 files with
96 kbps, Xing encoded + cover images, the same
images in every MP3 file)

[NickSD]

No one ever answered the question asked before... What is the reason for the bitrate drops in --xtreme and --standard in the new version of the encoder?

Also, I'm confused by your analysis of this site, Frank. I've never had a single problem with this site, let alone be confused by it. But...to each their own. For the record, I'd much rather use this site than use a newsgroup.

[JohnV]

The primary question raised again by NickSD was still not answered. :ponder:

[experttech]

I think this is deviating too much from the main topic. And the things behind he 'bitrate reduction' have not been addressed at all.

Appreciate if Frank (or someone else) could throw some light on whats behind this whole thingy of the significant birate reduction...

Or whether the MPC developers really felt what Garf said (and what I believe too) is correct and made the 1.04 versions

Cheers!
