Before you start
encoding your files you might want to know how big the resulting
.MP3 fill is probably going to be. For the encoding you can
select various frequency's and bitrates, resulting in various
sizes of the MP3's. If a .WAV-file is compressed,
the compression rate will be something between 10:1 and 14:1. To determine the real filesize for
every minute of .WAV file,
you can use this table:
| Encoding Bitrate: |
Mono / Stereo: |
Filesize [Mb]: |
| 256 kb/sec x 44,100 Hz |
Stereo (([-X-])) |
1.941 |
| 192 kb/sec x 44,100 Hz |
Stereo (([-X-])) |
1.455 |
| 160 kb/sec x 44,100 Hz |
Stereo (([-X-])) |
1.214 |
| 128 kb/sec x 44,100 Hz |
Stereo (([-X-])) |
.970 |
| 112 kb/sec x 44,100 Hz |

And now how to start encoding your .WAV files to .MP3's.
Step 1:
Open the MPEG Layer-3 Producer, and select your input file [*.WAV] and specify the output file [*.MP3]
Step 2:
Set the encoding frequency and bitrate by selecting one of the three preset encoding quality's or select one
yourself. If needed, you can use the above table to determine the filesize of the resulting MP3.
Step 3:
If you want to you can 'preview' the quality of the result. This means you can listen to the quality from
the resulting MP3 before you really start encoding it. This can be really usefull if you're not sure which quality
you'll need / prefer.
