Reduced duration of converted mp3

[Ries]

Hello there!

I have converted a mp3 file to a lesser bitrate in order to reduce its file size...this is working fine but unfortunately the duration of the file has also been reduced :( . It's original length of 78 minutes has been reduced to 43 minutes...apart from this everything goes well...I've listened to the converted and the original mp3, and the converted mp3 just stops after 43 minutes, whereas the original just goes on.

I've been using no presets, channels and frequency are set to as source and encoding is set to CBR...

Who knows what's going wrong????

Thanks in advance!!!

No DSP Effects? they could reduce the length.

Nope...none at all...

Is the original file duration shown when you hover over that file name?

No Christina...I've just noticed something peculair.

The conversion suddenly jumps to 100% and claims it's finished when it's only at 55%...55% of 78 = 43 so that's what's going wrong... :smile2:

Any clues on how come???

Re: Reduced duration of converted mp3

Some possibilities:
-Bad or unsupported tag information (such as album art, unicode characters, overly long comments field), this should resolve if you turn of the option to preserve ID Tags;
-too big a conversion-might try converting to wave and then to mp3 of reduced size;
-too funky an output setting (try some different bitrates);
-selecting option to delete source file after conversion (although if this was your problem, you would know it since you would no longer have your source file);
-sometimes having the converted file get stored in a different folder might help;
-or you might have a corrupted source file (in which case a test conversion would probably fail).
EDIT: You might also want to try setting Conversion Priority to Below Normal (this is set in the window that displays the progress of your conversion). This would help if the problem is the size of the conversion overtaxing your system.

Just some ideas. Keep us posted on what you find.

Best wishes,

Could also be a corrupt mp3 file (if the stream goes bad and it cannot resync an mp3 frame header it will end decoding).

Have you tried proxy-converting?

Basically, what I mean is: have you tried converting that mp3 to WAVE first, or some other lossless codec, and then convert it back to a bitrate you want on your final output mp3?

The file has no duration, so there's a problem with the source.

If it can be played, then dMC Auxiliary Input would be the better choice, though it's a long file.

Thanx for your replies!

Unfortunatly nothing seems to work...fiddling around with the mp3 settings, saving to another folder or deleting source file...everytime the same result: after 55% the conversions stops....

The same goes for a conversion to wav...it stops at 55%

So I'm truly starting to believe the mp3 file might be corrupted in some way...allthough it plays fine, as long as I don't try to convert it :(

Re: Reduced duration of converted mp3

So it's Auxiliary Input for you. Record to wav as you play. Then convert to whatever.

As long as this problem doesn't repeat itself in the future, yes, take ChristinaS's advice.

There might be a 4 GB recording limit. If you don't know what I'm talking about, don't worry about it unless you find that Auxiliary Input is giving you problems.

Good luck!

The most space a 78 minute audio file recorded in 16-bit 44.1KHz 2-channel stereo PCM wav will occupy is 800MB - that's less than 1GB.

Re: Reduced duration of converted mp3

It finally worked!!!

All I did was download the latest version from this site and it was working fine...so there was probably a problem with the older version I was running...

Thanx for all your replies!
