11.3.8. 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
(page
)) 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.
11.3.9. Search
This plugin can be used on playlists. It searches through the playlist that it opened on
looking for any occurrences of the string entered by the user. The results of this search
are saved to a new playlist,
search_results.m3u
, within the same directory as the
original playlist.
11.3.10. Shopper
Shopper is a plugin which allows you to maintain reusable shopping lists. To create a
list, use a text editor to write down a list of items (one per line; note that the line length
should not exceed 40 characters) and save the file as
<name>.shopper
. If you want to
separate the items you can do so by creating categories, which are prepended with ‘#’.
To open a
.shopper
file just “play” it from the file browser.
Example
#groceries
bananas
cucumber
4 apples
6 apples
#dairy
milk
