It does not support 32-bit floating point input. The encoder supports only 16-bit integer PCM input. Set the following attributes on the input media type. This attribute contains the 12 bytes of the MPEGLAYER3WAVEFORMAT structure that follow the wfx member of that structure.Īlternatively, you can fill in an MPEGLAYER3WAVEFORMAT structure and call MFInitMediaTypeFromWaveFormatEx to convert the structure to a Media Foundation media type. Use this attribute to specify the encoded bit rate. Next, click on Import Settings From here you can set the file type (ie: MP3) and overall quality of your conversion (Good Quality 128 kbps).

The default bit rates are 128 Kbps for mono and 320 Kbps for stereo. First, click on Preferences (PC users will find this under the Edit menu / Mac users find it under iTunes in the menu bar). Attributeīit rate of the encoded MP3 stream, in bytes per second. Set the following attributes on the output media type. The output type must be set before the input type.
