Basic easy use of WLAME.
WLAME is very simple to use when using the default and standard usage. All you have to do is drag the .wav file on to the WLAME icon, and away you go! The animation below demonstrates this.

In the above demonstration, we see the test.wav file being dragged on to the WLAME icon. This will result in a file called test.mp3, with a 192kbps Joint Stereo MP3 format.

The resultant window looks like this:

Now that you can use the basic features of WLAME, you may want to learn how to use the advanced settings and operations. These have been described in the section below.

 

Advanced usage:
WLAME may seem quite simple when using the basic operation mode, but when using the advanced mode, you can see just how powerful WLAME really is.

To use WLAME in advanced mode, you need to understand how to use switches. This can be done from the MS-Dos command line. 

To start click start->Run and type command, then click ok. If you have installed WLAME into c:\wlame, then type "cd wlame" and press enter.
Now your ready to begin, the most basic operation could be typed in like this:

"wlame test.wav"

This is the same as the basic operation mode. However, if you want a different filename as the output, to the input file then you'd type:

"wlame test.wav newname.mp3"

That is really the basic use of the WLAME advanced usage! Now you may want to use switches to set different parameters for the MP3 file. For example to change the bitrate, you'd simply type:

"wlame -b 128 test.wav newmane.mp3"

So all command line entries should be typed as follows:

wlame <switches> <in filename> <out filename>

Now that you understand how commands are given to WLAME, here is a table of all the switches and their usage.

Switch What it does Usage

--ABR

Turns on ABR mode. wlame --ABR infile.wav outfile.mp3

-b<rate>

Sets the CBR/minimum bitrate. wlame -b<rate> infile.wav outfile.mp3. Valid bitrates are: 32/40/48/56/64/80/96/112/128/160/192/224
/256/320

E.g/
"wlame -b224 infile.wav outfile.mp3"

-B<rate>

Sets the VBR maximum bitrate. wlame -b<rate> -B<rate> infile.wav outfile.mp3

-c

Marks the MP3 as copyrighted. wlame -c infile.wav

-GUI

Emulates the LAME screen output for LAME GUI's. wlame -GUI infile.wav outfile.mp3
This is only required when being used with a LAME front-end like razor lame. The usage of which has been described in the frontend.txt file.
-m<s|j|m|d> Sets the output/input sound mode. wlame -mj infile.wav outfile.mp3
If your input is stereo, then -ms and -mj simply set the output mode. Files cannot be converted to mono at the moment, so -md simply accepts the input as a mono file. The output will not be correct if used with a stereo input file.

-md sets dual-channel. It is not stereo! It can be used to provide sound in two different languages down two separate channels, in mono.

-o Marks file as a copy. (Not orignal) wlame -o infile.wav outfile.mp3
-p adds CRC protection data to the file. Quality will be reduced slightly, it used for streaming MP3's. wlame -p inflie.wav outfile.mp3
-private Marks the output file as private. wlame -private infile.wav outfile.mp3
-PROG<1|2> Sets the progress display. wlame -PROG1 infile.wav outfile.mp3

-PROG1 is the standard progress indicator.
-PROG2 is the statistics indicator.

--resample <rate> Sets the output sample rate. wlame --resample 32000 infile.wav outfile.mp3

 

-r Specifies that the file is RAW. wlame -r infile.raw outfile.mp3

This overides all default settings, so you must specify the files' sample rate, and sound mode. That is if the file is not 44.1Khz Stereo.

-s<frequency> Sets the samplerate of the input file. wlame -s44100 infile.wav outfile.mp3

Valid samplerates for input are:
32000/44100/48000.

See right --strictly-enforce-ISO Enforces strict encoding to the ISO specifications. Sound quality will be reduced slightly.
-vbr Turns variable bitrate on, using -b as the minimum rate, and -B as the maximum rate. wlame -vbr -b80 -B320
-V<0-9> Sets the variable bitrate quality. Will also turn on VBR too. wlame -V0 -b80 -B320

-V0 is the highest quality, and -V9 is the lowest.

As new switches are developed, they shall be added to the online manual.

Basic Notes

When dragging on Windows9x, the output filename might be in capital letters. This is an issue we are seeking to resolve.

 

 

 

 

 

 

The output screen may vary from this in future versions, so don't worry if the screen you get isn't quite like this one.

 

 

 

 

 

 

 

 

Advanced Notes

Advanced usage is not necessary for everyday use. If you just want to make MP3's for your MP3 player, then just use the basic operation as described above.

 

 

 

 

 

 

 

 

 

 

 

This table describes all the current switches, remember, that these switches are subject to slight change due to technical reasons. So watch out for any information given in the WARNING.TXT file, which can be found in the folder of this distribution.

All these switches, except for --ABR, -GUI and -PROG, are compatible with LAME.

 

 

 

 

 

 

 

 

 

 

 

Note: -GUI is also a progress indicator, it make WLAME look like LAME. It is not available under the -PROG switch.

Valid re-sample rates are:
8000/11025/12000/16000/22050/
24000/32000/44100/48000

 

 

 

 


This is overridden by the auto detect feature, unless the -r switch is found.
