Hi,

a new verison of the enc_aacPlus command-line encoder is available!

You all know, that "BASSenc" can be used with any external command-line tool to encode sample data, if that tool supports STDIN to receive sample data and STDOUT, to receive back the encoded data.
So far there was no command-line tool available, which supported AACplus V2 encoding like this.
Now there is ;-)

Here is the download link: http://www.un4seen.com/filez/4/enc_aacPlus.zip

The trick is, that this tool uses the AACplus v2 encoder provided with Winamp 5.33 or above!
So if you install Winamp, you get this legally for free.

enc_aacPlus.exe was originally provided by Dmirty Alexandrov.
I just made a few adjustments (see below)...

NOTE!
"enc_aacplus.dll" and "nscrt.dll" must be copied into the directory of enc_aacPlus.exe!
Get these two dll's from your Winamp 5.33 or above plugins directory!

Usage:
        enc_aacPlus.exe <wav_file> <bitstream_file> [options]

Input/Output:
        <wav_file>       : WAV input file (use - to read from STDIN)
                           (must be PCM 8 or 16 bit, 32000, 44100 or 48000 Hz)
        <bitstream_file> : Bitstream output file (use - to write to STDOUT)
                           (mp4box not possible, if STDOUT is selected)

Options:
        --br <bitrate>   : Set bitrate (CBR) in bps. Default is 128000
        --ps             : Enable Parametric Stereo (bitrates up to 56000, only with HE-AAC)
        --is             : Prefer Independed Stereo (disables Joint Stereo M/S coding)
        --mono           : Encode as Mono
        --mpeg2aac       : Force MPEG2 AAC (instead of let the encoder choose)
        --mpeg4aac       : Force MPEG4 AAC (instead of let the encoder choose)

        --high           : Encode as HE-AAC+ with hight bitrates (bitrate up to 256000, multichannel not supported)
        --mp4box         : Wrap result into MPEG4 container (MP4BOX.EXE must be in the same directory)
        --mp4mux         : Output MPEG4 ISO compilant file .mp4 instead of raw .aac (MP4MUX.EXE must be in the same directory)
        --silent         : Set silent mode, no progress and other output
        --rawpcm <r c b> : Signal RAW PCM input intead of WAV
                 <r>     : Samplerate in Hz (32000, 44100 or 48000)
                 <c>     : Channels count (1 or 2 or above)

enc_aacPlus.exe input.wav out.m4a --br 32000 --he --mp4box
enc_aacPlus.exe - - --br 128000 --high --silent --rawpcm 44100 2 16

I have no idea if the Nero encoder supports StdOut, but it certainly supports StdIn which should be enough if one only needs to encode data.

[radio42]

Yepp, that's true.
The nero Encoder tool only supports STDIN, which is sufficient for creating AACplus files.
But it does not support STDOUT, which is needed, if you want to get the encoded data back - e.g. if you want to stream the data to a SHOUTcast server ;-)

[Intimidated]

I would just like to say THANK YOU.

i've just spent hours trying to find an encoder with this functionality, and I should've looked on the BASS forums in the first place.

Thanks to BASS, I have now created a stream transcoder which has the capability of reading MP3, AAC/HE-AAC, Ogg Vorbis,  WMA and Ogg Flac, and can transcode into MP3 OGG and AAC Plus.

I cant thank you guys enough.

[radio42]

You're welcome

[KtoY]

Hi radio42, i want to know, how use enc_aacplus.dll without enc_aacplus.exe?

[radio42]

Since it is a regular Winamp plugin it must use the Winamp PlugIN API as documented by Winamp...

So each encoder implements an interface class called "AudioCoder".
You just need to query for the "CreateAudio3" process address in the dll, create an "AudioCoder" instance of that one and then call the "Encode" method for each chunk of data you are processing...

All the rest is (more or less) documented on the Winamp pages ;-)

[KtoY]

Thanks

I am using as a basic source of example to mp3 and ogg. Let me a hint to make use of encryption to MP4 (aacp). Does anyone know what I say a command line?

///VEJA >> SEE

  // setup encoder command-line (raw PCM data to avoid length limit)
  if chk_Mp3.Checked then
  begin
    Content := BASS_ENCODE_TYPE_MP3;
    Comline := PChar(Format('lame -r -x -s 44100 -b %d -', [bitrate]));
  end
  else
  begin
 Content := BASS_ENCODE_TYPE_OGG;
     Comline := PChar(Format('oggenc -r -R 44100 -b %d -m %d -', [bitrate, 16]));
      // for better Quality on ogg just use -q (-2.0 - 10.0}

  end;

[Bert]

Dear Bernd,
i'm sorry, but what is new now?
I evaluate this for a long time now, my problem is that the encoder produces always a loud haerable click at the start of the recording.
Is this better now?

Best, Bert.

[radio42]

Hi Bert,

I might not fully understand your question?
a) "What is new now"?
-> To what are you referring - v2.4? enc_aacPlus.exe is there for quite some time and hasn't changed since then! It was just constantly adapted to always work with the latest BASS version.

b) "Lound hearable click"
-> I never noticed something like this - in all my tests there is absolutly no click. So I guess this is not related to enc_aacPlus.exe - but might be related to something else in your environment.
Do you have some code on how you use it?

  end

[radio42]

Have you copied the required Winamp files as well?
These are: "enc_aacplus.dll" and "nscrt.dll" from a Winamp 5.2 installation.

[Mickael]

Whooops.. no! It's ok :-)
Thank you!

[Mickael]

and MP2 ? (Mpeg 1 layer 2)

[radio42]

You should ommit the "-x" flag, as twolame already uses little-endian.
Also you need to either specify the "--samplesize" or the "--samplefloat" flag depending on your input format as well as the "-N" flag.
E.g.:
"'twolame -r -s 44100 --samplesize 16 -N 2 -b..."

Hello radio42,

I'm tested the config on command line:

C:\>twolame -r -s 44100 --samplesize 16 -N 2 -b 128 -
Missing output filename.

Try "twolame --help" for more information.

Missing output filename ?

[radio42]

Yes sure, that's why I placed the "..." in my above comment, as I thought you know the rest of the command-line, as it it listed in the twolame help ;-)

[Mickael]

   
Hello radio42.
Sorry I did not understand very well your answer. (I'm French)

This line does not work:

Comline := PChar(Format('twolame -r -s 44100 --samplesize 16 -N 2 -b %d -', [bitrate]));

Do you have any idea why?
Thank you
