good method for wav to ac3 for a dvd-video?

[loki03]

hy!
does anybody of you know of a simple guide for transcoding stereo wav to 2.0 ac3 without any change in dynamics etc? thx

[loki03]

well, i tried twolame with 384kbps, sound was fine, playback was fine in powerdvd, but my philips-dvd-player refuses to detect a soundtrack...

just load the wav into belight and select as output AC3 Stereo and the desired bitrate.
Twolame is for mp2 (that´s why two(2)lame), not ac3.

just trying this, but its difficult to get a setting that preserves the volume

HeadAC3he v0.24-a13 by Dark Avenger 15.12.2004 with Gain 6 dB to obtain near 100% volume output.

How encode wav to ac3 using HeadAC3he v0.24-a13
Left panel:
- Select Source file and Destination Format AC3, rest unchecked.
- Warning: encode to ac3 5.1 require a 6 channel wav mapped FL_C_FR_SL_SR_LFE (Use WaveWizard with the preset "ac3 order for SoftEncode or ac3enc" to remap a wav with standard order FL_FR_C_LFE_SL_SR)

Right panel:
- Downmix Type desired (without effect for stereo input, select 6 ch for ac3 5.1)
- Individual input/output channels to 0 dB, No DRC (DRC always without effect)
- Global Gain 6 dB
- Low pass filter for surround (without effect for 2 ch output, for 5.1: checked or unchecked always do the low pass filter)

Second Right panel (click in Options button):
- Bitrate desired (192 recommended for 2 ch, 448 for 5.1).
