\subsection{MP3 Encoder}
|
|
This plugin encodes a \fname{.wav} file to MP3 format. The supported
|
|
input format is uncompressed, linear PCM with 16 bit per sample and a maximum
|
|
of 2 channels. Allowed sample rates are 16, 22.05, 24, 32, 44.1 and 48~kHz.
|
|
The user will be asked to select the desired output bitrate of the compressed
|
|
MP3 file.
|
|
|
|
\begin{description}
|
|
\item[Select Bitrate] The following bitrates can be selected: 64, 80, 96, 112,
|
|
128, 160, 192, 224, 256, 320~kbps.
|
|
|
|
Remark: Bitrates above 160~kbps cannot be used in MPEG~2 Layer~3 bitstreams.
|
|
The encoder plugin automatically limits the output bitrate to 160~kbps for
|
|
input files with a sample rate of 16, 22.05 or 24~kHz. The same limitation is
|
|
valid for mono files.
|
|
\end{description}
|
|
|
|
The output \fname{.mp3} file is written to the same path as the \fname{.wav}
|
|
file using the same filename. To use this plugin, open the \setting{Context Menu}
|
|
(see \reference{ref:Contextmenu}) on a \fname{.wav} file and select
|
|
\setting{Open With\dots $\rightarrow$ mp3\_encoder}.
|
|
|
|
\note{
|
|
The encoder will choose the appropriate bitstream format from the sample rate
|
|
of the input file. The output bitstream format is MPEG~1 Layer~3 for 32, 44.1
|
|
and 48~kHz, and MPEG~2 Layer~3 for 16, 22.05 and 24~kHz. MPEG~2.5 Layer~3 is
|
|
not supported.
