MPEG-1 Layer 2 Encoding Dialog
On saving an MPEG-1 Layer 2 (MP2) audio file, you can adjust the encoding settings.
You can open the MPEG-1 Layer 2 Encoding dialog from most places where you can select an output file format.
Example
Open an audio file. Select . Click in the Format field, and select Edit. In the Audio File Format dialog, set MPEG Layer-2 as the type. Click in the Encoding field, and select Edit.
- Bit Rate
-
Determines the bit rate. The bit rate is related to the quantity of data that is used to encode the audio signal. The higher the value, the better the quality, but the larger the output file.
- Stereo Encoding
-
In Standard mode, the encoder does not use the correlation between channels. However, the encoder can take space from a channel that is easy to encode and use it for a complicated channel.
In Joint Stereo mode, the encoder uses the existing correlations between the two channels to increase the ratio quality/space.
In Dual Mono mode, both channels are independently encoded. We recommend to use this mode for signals with independent channels.
- Specify as Original Recording
-
Marks the encoded file as the original recording.
- Write Private Bit
-
A custom flag.
- Write Copyright Flag
-
Marks the encoded file as copyright-protected.
- Write Check-Sum
-
Allows other applications to check the integrity of the file.
- Encode Peaks (Ancillary Data)
-
Must be activated for compatibility with specific systems, such as DIGAS.
