The Advanced FLAC and Ogg Vorbis Actions are new in Myriad. If you want to convert files to FLAC or Ogg Vorbis using the default settings for those encoders, use the standard Actions. However, if you want to configure additional options for these formats, the Advanced Actions are for you.


Convert To FLAC (Advanced)

Bit Depth: Options are 8, 16, 24 and 32-bit.

Mid Side Encoding: This is only for stereo files and tends to increase compression by a few percent on average. Options are Enabled or Disabled.

QLP: We won't get in to what QLP means here. Suffice it to say, don't change this unless you fully understand QLP. Options are Default or Consider neighboring values.

Order Models: See QLP. Options are Estimate and Evaluate All.

Max Order: See QLP and Order Models. The center detente on the slider is the default.


Convert To Ogg Vorbis (Advanced)

Bit: Options are Constant, Variable and Average.

Target: Tells the encoder to attempt to encode at approximately this bitrate. Options range from 48 to 500 kbps.

Minimum: Sets the minimum bit rate. Options range from 48 to 500 kbps.

Maximum: Sets the maximum bit rate. Options range from 48 to 500 kbps.

Lowpass Filter: Sets the lowpass frequency. The range is from 2 kHz to 99 kHz.

Impulse Bias: A negative bias tells the encoder to pay particular attention to the crispness of transients in the encoded audio. The range is from -15 to 0.
