12.3.8. MP3 Encoder
This plugin encodes a .wav file to MP3 format. The supported input format is uncom-
pressed, 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.
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.
The output .mp3 file is written to the same path as the .wav file using the same
filename. To use this plugin, open the Context Menu (see section 4.1.2 (page 24)) on
a .wav file and select Open With. . . → mp3_encoder.
Note: The encoder will choose the appropriate bitstream format from the sample rate of
b
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.
