MPEG 1 Layer 3 files
MPEG 1 Layer 3 files have the extension “.mp3”. By use of
advanced audio compression algorithms, MP3 files can
be made very small, yet maintaining good audio quality.
In the File Format section, the following options are avail-
able for MPEG 1 Layer 3 files:
Ogg Vorbis files
Ogg Vorbis is an open source, patent-free audio encoding
and streaming technology, offering compressed audio
files (extension “.ogg”) of small size, but with compara-
tively high audio quality.
In the File Format section you will find only one setting: the
Quality fader. The Ogg Vorbis encoder uses variable bit
rate encoding, and the Quality setting determines be
-
tween which limits the bit rate will vary. Generally speak-
ing, the higher the Quality setting, the higher the sound
quality but also the larger the files.
Windows Media Audio Pro files
(Windows only)
This is a continuation of the Windows Media Audio format
developed by Microsoft Inc. Due to the advanced audio co-
decs and lossless compression used, WMA Pro files can
be decreased in size with no loss of audio quality. Further-
more, WMA Pro features the possibility of mixing down to
5.1 surround sound. The files have the extension “.wma”.
When you select “Windows Media Audio File” as the file
format, you can click the “Codec Settings…” button to
open the “Windows Media Audio File Settings” window.
Note that the configuration options may vary, depending
on the chosen output channels.
General tab
In the Input Stream section, you set the sample rate (44.1,
48 or 96 kHz) and the bit resolution (16 bit or 24 bit) of the
encoded file. Set these to match the sample rate and bit
resolution of the source material. If no value matches that
of your source material, use the closest available value
that is higher than the actual value. For example, if you are
using 20
bit source material, set the bit resolution to 24 bit
rather than 16
bit.
Ö The setting in the Channels field depends on the cho-
sen output and cannot be changed manually.
The settings in the Encoding Scheme section are used for
defining the desired output from the encoder. Make set
-
tings appropriate for the intended use of the file. If the file
will be downloaded or streamed on the Internet, you might
not want too high bit rates, for example. See below for de
-
scriptions of the options.
Option Description
Bit Rate fader By moving this fader, you can select a bit rate for the
MP3 file. As a rule, the higher the bit rate, the better the
audio quality and the larger the file. For stereo audio,
128
kBit/s is often considered to result in “good” audio
quality.
Sample Rate
pop-up menu
On this pop-up menu you can select a Sample Rate for
the MP3 file.
High Quality
Mode option
When this is activated, the encoder will use a different
resampling mode, which can give better results de
-
pending on your settings. In this mode, you cannot
specify the Sample Rate, but only the Bit Rate for the
MP3 file.
Insert ID3 Tag
option
This allows you to include ID3 Tag information in the
exported file.
Edit ID3 Tag
button
When you click this, the ID3 Tag dialog opens, in which
you can enter information about the file. This additional
information will be embedded as text strings in the file,
and can be displayed by most mp3 playback applica
-
tions.
