Type: Int32
Sets the compression level
The compression level is roughly proportional to the amount of effort the encoder expends to compress the file. A higher level usually means more computation but higher compression. The default level is suitable for most applications.
Currently the levels range from 0 (fastest, least compression) to 8 (slowest, most compression). A value larger than 8 will be treated as 8.

Type: Four
True if the filter is using hardware acceleration.
Note: This property is read only.
Type: Bool
Number of audio frames introduced or removed by the audio compressor.
A positive value indicates frames have been added, a negative value indicates frames have been removed. This property may be found on the audio compressor after Begin has been called.
Note: Read-only property.
Type: Int32
Loudness measurement mode.
The DTS:X audio output may containe an embedded loudness value from -40.0 LKFS to 0.0 LKFS. For some of the loudness modes (Input, Target), the LKFS property will be used. For other modes, the LKFS member will be ignored.
Type: LoudnessMeasurementType
Target bitrate for the encode.
The supported bitrate must be one of 160000, 192000, 224000, 256000, 288000, 320000, 384000, or 448000. Any other values will result in the SDK rejecting the configuration.
Type: Int64
SMPTE Start Timecode
The encoded audio generated contains an SMPTE Timecode. The Timecode may be set to a valid drop (00:00:01;00) or non-drop SMPTE Timecode (00:00:01:00).
Note: By default the timecode is ‘00:00:00:00’.
Type: String
Loudness, K-weighted, relative to full scale.
The value in LKFS may range from -40.0 to 0.0. Depending on the setting for the LoudnessMeasurement, the LKFS value may be ignored, stored directly as the embedded loudness value in the output DTS:X audio bitstream, or the output DTS:X audio may have its loudness adjusted to have the loudess specified in LKFS.
Type: Float
Sync internval in seconds.
DTS:X Profile 2 audio contains periodic synchronization frames, separated by some number of non-synchronization frames. When SyncInterval is set to a value greater than zero, synchronization frames will be generated as close to that number of seconds as possible, dithering where necessary. A value of 1 in SyncInterval will generate a synchronization frame in the output DTS:X Profile 2 audio every second.
Note: Valid values for SyncInterval are 0 to 10, inclusive. SyncInterval will not be used if it is zero or if SyncIntervalFrames is non-zero. Should both SyncIntervalFrames and SyncInterval be zero, a default synchronization frame interval of 47 will be used.
Type: Int32
Sync interval in DTS:X Profile 2 frames.
DTS:X Profile 2 audio contains periodic synchronization frames, separated by some number of non-synchronization frames. If a specific synchronization interval is required, set SyncIntervalFrames to that interval. Setting SyncIntervalFrames to 47 will generate a synchronization frame in the output DTS:X Profile 2 audio every 47 frames.
Note: Valid values for SyncIntervalFrames are: 0, 47, 94, 141, 188, 235, 282, 329, 376, 423, and 470 SyncIntervalFrames will not be used if it is zero. Should both SyncIntervalFrames and SyncInterval be zero, a default synchronization frame interval of 47 will be used.
Type: Int32
Embed T1CC flag in encoded bitstream.
When non-zero, the Type One Certified Content (T1CC) flag will be set in the encoded audio.
Note: Defaults to false.
