need help with BeSplit

[zxO]

Hi everyone,

First of all, I want to thank you all for putting so much work in all this, your programms/guides/etc really helped me a lot...

OK, I've got some questions to BeSplit:

1. In the readme of BeSplit0.9b6 is written "for ota's switches, read attached 'ota.txt'", but I couldn't find that file anywhere

2. The line in the audio-faq for normalization of mp2-files
(BeSplit -core( -input infile.mp2 -output outfile.mp2 -type mp2 ) -ota( -G max ))
outputs on my pc an identical copy of the infile without processing. After some testing I found out that it works correctly if you write the "-type mp2" before the "-output..." switch:
BeSplit.exe -core( -input C:\Test\test.mp2 -type mp2 -output C:\Test\out.mp2 ) -ota( -G max )
I also tried BeSliced and when I select "Normalize" than it outputs again an identical copy, but if I select "Normalize+Header" than it does both normalization and adds a Wav-Header. Well, that's not directly a question, just wanted to point that out...

3. Finally, I can't get the fade-in plugin to work. I used the commandline from the readme:
BeSplit.exe -core( -input C:\Test\test.mp2 -type mp2 -output C:\Test\out.mp2 ) -plugin( -name BS_FadeIn.dll -func FadeInNormal )
and again I get an unprocessed copy. What am I doing wrong?


Thanks for all help

First, welcome to the forum zxO.

2. I am quite sure that you used a correct command line to normalize your MP2 file with BeSplit. If the output you get is really identical with the input file I just can guess that your file is already normalized and BeSplit didn't do anything, but:

To be sure what's going on, never forget to post a logfile. Change your command line to the following:

besplit -core( -input infile.mp2 -output outfile.mp2 -type mp2 -logfile BeSplit.log ) -ota( -G max )

Please, post the contents of that logfile here.

3. The fade-in plugin is not meant for use with BeSplit. It is a plugin for BeSweet and in order to fade in your MP2 you have to re-encode the file. While I am sure that you don't want to do that, as you undoubtedly would lose quality, you may do so like this:

besweet -core( -input test.mp2 -output out.mp2 -logfile BeSweet.log ) -mp2enc( -b 224 -m s -e ) -plugin( -name BS_FadeIn.dll -func FadeInNormal )

4. One thing is very important in the usage of BeSweet/BeSplit command line: Always make sure that you have a blank between an opening bracket and the first switch and the last switch and the closing bracket, e.g.

-core( -input in -output out )

Thanks for your reply, tiki4

I tested everything again (always with the same, not normalized mp2), and here are the results:

Both files were correctly normalized, I don't know why it works now, BUT...

As you can see, I tried it again with BeSliced and here I get the same results as in my first post (BTW I use WinXP). Very strange...


While I am sure that you don't want to do that, as you undoubtedly would lose quality, you may do [...]

You're absolutely right, I record digital radio, which is broadcasted in mp2, and it would save time/quality/HD-space if I could fade and normalize my recordings without any decoding/encoding


besweet -core( -input test.mp2 -output out.mp2 -logfile BeSweet.log ) -mp2enc( -b 224 -m s -e ) -plugin( -name BS_FadeIn.dll -func FadeInNormal )

But that does transcoding, right? Doesn't that also degrade the quality?

--edit: some word wrap

Hi,

I'm not sure about BeSpliced, I never used it, but in your third example there is at least a closing bracket after the core section missing. Can you try again to normalize first (as you already did) and then add the RIFF header (omitting the -G max) this time?

You're right, the example command line for BeSweet I gave you does transcoding and you would surely lose some quality. If you can hear that is another question. However, I don't know of a method to fade-in a file without transcoding. What's the bitrate you get from your radio? I think the higher the bitrate, the less pronounced should be transcoding artefacts.

Sorry for the late response, had a lot of stuff to do

Hey, you're right, why didn't I see that...

Do you mean with BeSpliced or with commandlines? Well, I tested both and both worked. So I guess the problem with plain normalization is a bug in BeSpliced.

Digital radio is in 48kHz 192 kbit (real) stereo with CRC.
Is it possible to cut the mp2-file after five seconds or so, then transcode just the "five-second-file" and then join them back together? I know that this is not possible with mp3, but I don't know about mp2

Just read the examples that come with BeSplit. I guess you find out how to cut and join MP2 with this program :)
