Bw and Fs – Bit width Resolution and Sampling Frequency of Audio Channels
All audio files entered for any channel layout must have the same bit-width resolution (Bw) and sampling
frequency (Fs).
Note: If the sample rate of the input material does not match the selected sample rate in the
Sample Rates drop-down menu, when the ‘Encode” button is selected, an error message will be
displayed indicating that there is a mismatch. Unless the error is corrected, the user will not be
able to create an encoded file.
Clear All
Located below the Input Files section of the GUI, the
button will unload all active input
files from their related channel inputs when clicked.
7.2.9 Dialog Normalization
Located in the upper right side of the Audio panel, the Dialog Normalization menu allows a value to be
selected for the specified encode (as shown in Figure 7-7). These values range from -1 to -31 dBFS
LeqA. The default value is -31 dBFS LeqA, which corresponds to no attenuation, in effect turning dialog
normalization OFF. At current, all 6.x Discrete channel layouts require a -31 dBFS Dialog Normalization
setting. Dialog Normalization is a post-process operation performed by the DTS decoder. DTS
recommends leaving the Dialog Normalization setting at -31.
