MPEG-1 Layer 2 Encoding Dialog

You can open the MPEG-1 Layer 2 Encoding dialog from most places where you can select an output file format. For example, open an audio file, select File > Save As, click in the Format field, and select Edit. In the Audio File Format dialog, select MPEG-1 Layer 2 as type, click 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 mode, the encoder uses the existing correlations between the two channels to increase the ratio quality/space.

In Dual mode, both channels are independently encoded. This mode is recommended for signals with independent channels.

Specify as Original Recording

Marks the encoded file as the original recording.

Write Private Bit

This is 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)

This must be activated for compatibility with specific systems, for example, DIGAS.
