a)Test for BandWidthFilter
Using a test wav 6 chan 48000 Samples/sec. (24 seconds tone test from 0 Hz to 24 KHz)
Encoded at 448 kbps (Nominal BandWidth = 20.3 KHz)
BandWidthFilter = On -> Progressive cut from 19.4 to 19.8 KHz
BandWidthFilter = Off -> Irregular cut from 20.3 to 20.4 KHz
Encoded at 320 kbps (Nominal BandWidth = 15.8 KHz)
BandWidthFilter = On -> Progressive cut from 15.0 to 15.5 KHz
BandWidthFilter = Off -> Irregular cut from 15.8 to 15.9 KHz
Then the switch work, another question is recommend it.
Before the test I think not see so clearly the differences.
b) Just like other switch you must invert On -> Off
This switch is ignored when you check TimeStamp. In Soft Encode Help:
"Time stamped frames are automatically not stored in Intel byte order."
Soft Encode uses 3 frame types:
-Non-Intel, First byte 0x0B -> run Ok in all soft. Default or with:
Add Time Stamp = Unchecked
Save frame in Intel byte order = Unchecked
-SMPTE, First byte 0x01, byte 17 0x0B (rest of frame like Non-Intel) -> Are played ok (ignoring the first 16 bytes), rejected from GraphEdit and DVD Authoring software. Activated with:
Add Time Stamp = Checked
-Intel, First byte 0x77 -> Only know the proper Soft Encode to open it. Activated with:
Save frame in Intel byte order = Checked
Add Time Stamp = Unchecked
I don't know the use of Time Stamp or Intel byte order.
c) Switches with ? aren't inverted by the switch in cb Configure, then don't work properly.
All switches must be inverted. And the Dialog Norm must be the same value than selected, now is value - 1.
EDIT: (ignoring the first 16 bit) must be (ignoring the first 16 bytes),
