1 \subsection{MP3 Encoder}
2 This plugin encodes a \fname{.wav} file to MP3 format. The supported
3 input format is uncompressed, linear PCM with 16 bit per sample and a maximum
4 of 2 channels. Allowed sample rates are 16, 22.05, 24, 32, 44.1 and 48~kHz.
5 The user will be asked to select the desired output bitrate of the compressed
6 MP3 file.
8 \begin{description}
9 \item[Select Bitrate] The following bitrates can be selected: 64, 80, 96, 112,
10 128, 160, 192, 224, 256, 320~kbps.
12 Remark: Bitrates above 160~kbps cannot be used in MPEG~2 Layer~3 bitstreams.
13 The encoder plugin automatically limits the output bitrate to 160~kbps for
14 input files with a sample rate of 16, 22.05 or 24~kHz. The same limitation is
15 valid for mono files.
16 \end{description}
18 The output \fname{.mp3} file is written to the same path as the \fname{.wav}
19 file using the same filename. To use this plugin, open the \setting{Context Menu}
20 (see \reference{ref:Contextmenu}) on a \fname{.wav} file and select
21 \setting{Open With\dots $\rightarrow$ mp3\_encoder}.
23 \note{
24 The encoder will choose the appropriate bitstream format from the sample rate
25 of the input file. The output bitstream format is MPEG~1 Layer~3 for 32, 44.1
26 and 48~kHz, and MPEG~2 Layer~3 for 16, 22.05 and 24~kHz. MPEG~2.5 Layer~3 is
27 not supported.
