WAV to MP3 /BeSweet

[castellanos]

Hi there!
I am really new on audio encoding using BeSweet, nice tool seems to be... I wanted to make a few tests, for instance, a Wave to Mp3 convertion. Everything was possible, but I didn't see the possiblity to change the Bitrates.
After I made a few mp3, I realize that the selection of bitrates was, may be, by default :confused:
Very curious... I played the final mp3 on Win Media Player and showed 324 Kb/s... and the same file with Nero Media Player showed 174 Kb/s :confused: :confused: :confused:
Please help!
Greetings!

Please post your besweet logfile. You can definitely specify a bitrate or quality setting with the lame encoder through besweet.

Hi and thank you for your quick reply!
I investigated a little more, and I've made my own presets (I didn't know I've supposed to do that) and now I can create any mp3 with any bitrates. My preset look like this (for mp3 44.1 khz at 192 Kb/s):

MP3(192Kb/s) 44.1=-azid( -c normal -L -3db ) -ota( -hybridgain ) -ssrc( --rate 44100 ) -lame( -b 192 )

It works!
It is ok or you think the preset should be different?
Please help!
Greetings!

Well, when MP3 is your destination format, there is no reason to resample to 44.1 khz, there should be no problems with keeping the source sample rate - meaning you can eliminate the -ssrc section.

The hybridgain and azid sections look good.

If you want a constant bitrate (CBR) encode, your lame section looks good - if you want a higher quality VBR MP3, change your lame section to -lame ( --alt-preset 192 ), or even higher quality, -lame ( --alt-preset standard).

I got it! Nice to know!
One thing more and in order to know more about audio encoding, this time with mp4.
I got the Command line program for AAC encoding by PSYTEL RESEARCH and I would like to know (if you know or somebody in this forum) how to create a comand line to make it work with this program.
Plaese help!

Psytel's AACenc does not work directly with BeSweet. The most highly recommended/popular methods for transcoding AC3 to MP4 are:

Transcode directly from AC3 to Nero's MP4 codec using bsn.dll (included with besweet). This requires a purchased or trial version of Nero.

(freeware): Transcode from AC3 to FAAC's AAC codec directly using foobar2000, or decode to wav with BeSweet, then encode with FAAC.

Use the search function, and check the AAC FAQ for more information.

Hi, and thanks a lot for all the information.
I have an original version of NERO, so it is no problem to encode audio files into mp4, but I just wanted to know a little bit more with other programs... and considering that they are all freeware...:D

First of all, I was trying to convert a wave into (mp4/aac) with BeSweet, but I get this error message:

And I don't know why, the bsn.dll is there! :(

Second: I know that Psytel AAC Encoder does not work together with BeSweet, but anyway, Could you explain me how to make a comand line for that program?
Thanks! :)

[castellanos]

Nobody want to answer that question? :(

Pystel AAC is an old crappy AAC encoder. So don't use it. Nero will give you better quality for the same bitrate.

Windows Media Player is a very crappy player, it can't even show the bitrate right, so don't use it.
Try Winamp (www.winamp.com) or Foobar (www.foobar2000.com) or any other player for audio. And Media Player Classic (http://sourceforge.net/projects/guliverkli) for video.

[castellanos]

I apreciate very much your advice, but can "please" somebody tell me how to make a comand line for that program :angry: I am just curious.
Greetings! :D

[castellanos]

Well, I think nobody know the answer to that one :(
Pitty.

Hi castellanos,

Note that psytel's AAC encoder shouldn't be used for 5.1 streams due to a channel mapping bug. AACMachine is a gui for going from AC3 to AAC using psytel, you may want to look into it. Otherwise, check the helpfile included with the psytel encoder package.

Maybe you shouldn't ask AAC related questions in a thread about WAV to MP3... ;)

http://faac.sourceforge.net/oldsite/wiki/index.php?page=PsyTEL

And if you start PsyTEL AACEnc in the console by simply typing "aacenc", it should give you the help screen with all options.
