1) Where can I find the "WAV dest filter"? It's not in my list.
2) In the procedure it says: connect audio decoder to intervideo audio processor, but there is no audio decoder.
3) How do I give the "file writer filter" an output name?
Procedure:
- In GraphEdit go to File > Render Media File... > Open your 2-channel audio file
- Delete the Default DirectSound Device filter
- Go to Graph > Insert Filters... > DirectShow Filters > InterVideo Audio Processor Fx > Insert Filter
- Also insert the WAV Dest filter and File writer filter with an output filename e.g. output.wav
- Connect the audio decoder to InterVideo Audio Processor Fx, then WAV Dest, then the File writer filter
- Right click the InterVideo Audio Processor Fx filter > Filter Properties... > 6 SPEAKER
- Go to InterVideo Container DMO > InterVideo EXP DMO > Append <---
- Click Play and then immediately click Stop to 'initialise' the filter
- Go back to Filter Properties > InterVideo EXP DMO tab > ProLogic2
- Click Play and wait until the button reactivates
- The output file has an incorrect 2-channel WaveFormatEx header!
- Use a hex editor to change:
- nChannels at 16 from 02 to 06
- nAvgBytesPerSec at 1C from 00 EE 02 to 00 CA 08 if your audio is 48 KHz, or from 10 B1 02 to 30 13 08 if it is 44.1 KHz
- nBlockAlign at 20 from 04 to 0C
- You now have a Dolby Pro Logic II upmixed 6-channel WAV file! (empty .1 channel)
