The LEAD AAC Encoder is a DirectShow filter for compressing audio data using the AAC compression standard (ISO/IEC 13818-7). The AAC standard delivers high quality audio at lower bitrate compared to other audio encoding standards like ISO/MPEG Audio Layer-3; MP3.
This encoder offers both variable bitrate and constant bitrate. However, due to a limitation in the AVI multiplexer , the encoder offers constant bit rate only if it is connected to the AVI multiplexer.
Technical details for the filter are provided in the following table:
