EASY BATCH FILES FOR USERS under WINDOWS:


1) PURPOSE:

These example batch files are intended to do easy mass conversion of files present
in one same folder, without needing to enter the command line console.


2) INSTALLATION

Copy the .BAT files in a working folder that you've created on your disk.
Copy also from the present archive to your working folder or to a location with declared path:

- NORCOM.EXE
- FFMPEG.EXE that you've downloaded from http://ffmpeg.zeranoe.com/builds/win32/static/


3) USE:

To extract audio from .FLV files present in the folder, then "norqualize" it, and
finally encode it to MP3, simply launch ALLFLVEQ (from the desktop file explorer).

To "norqualize" already existing MP3 files present in the folder, launch
ALLMP3EQ (from the desktop file explorer). New equalized files will be appended with ".WAV_eq.MP3".

Tips: You will see by editing the BAT files (right click + modify) that you just have to change the
extension name written in the first line to adapt the script to other types of multimedia files:
Example: "for %%X in (*.mp3)" can be replaced by: "for %%X in (*.avi)" for creating a new command.
Always for example, save it as ALLAVIEQ.BAT.

NOTE: Before launching any process in the working folder, ensure that source file names does not
include any space or "weird" character. Replace spaces by underscores '_'


4) FILE STORAGE:

After you've checked that the result is satisfying, do as follows to prevent useless and
confusing multiple conversions during the next use:

- Move your converted files to your usual MP3 collection folder(s).
- Delete the source files that you don't need anymore.


5) Using NORCOM.EXE alone and directly from the command line:

Common syntax is:  NORCOM [input file] <options>

[input file] must be a WAV file.
The use of the included BAT file MP3EQUAL plus the installation of FFMPEG are required for processing other files.
(Note that MP3EQUAL can be used for audio extraction from other files than MP3, as soon as the formats are handled by FFMPEG)

The supported options in the NORCOM command line are:

-R : When present, this flag makes norqualizer encode / re-encode the final result to MP3.
     Anyway at least a WAV file will be generated (to be prefered for audio CD burning).
     Note: This option will have a real effect only if NORQUAL is called from the MP3EQUAL.BAT file
     (See next part: non-WAV multimedia files)

-B : Reduces bass profile. To be used only for tracks having no bass line nor beats at all.

-F : Forces the loading of WAV files where the format and data header were not identified correctly.
     (In this case, assumes that the stream is at 44100 spl/s, stereo, big endian)

-V : Activates the click and pop discriminator in case where soundtracks have been extracted from vinyl records.
     (In this case clicks and pops are not taken into account for normalization because they can be clamped.
     Note that clips and pops are not removed. This is not the purpose of NorQualizer.)


NB: For MP3 re-encoding FFMPEG must also be installed.

Generally, when extracting audio from various other multimedia files (avi, mpg, flv, ogg...) before
processing and/or audio CD burning, prefer the use of temporary WAV files at 44100Hz, stereo.

Example with FFMPEG:  ffmpeg -i my_multimedia_file -f wav -ar 44100 -ac 2 my_extracted_file.wav
Then launch: norcom my_extracted_file.wav -R

The less conversions are done, the better final quality will be. Therefore if the audio track has to
be extracted for example from a video file, directly convert video to WAV and then call norqualizer.
(This way of proceeding is what MP3EQUAL.BAT does automatically if it is called with the source
multimedia file as input).


For the same reasons, when burning an audio CD use the "norqualized" WAV file instead of using the
MP3 one. (Else it will be discretely converted back to WAV-like format by the burning software).
