DTS to Stereo Dolby Digital 2.0 (AC3)
(back)

Works for Stereo tracks only.
Else the channel order is wrong!

Foobar2000 Method (special installer) with DTS-Plugin

Foobar2000 is able to convert DTS into all formats for which an encoding plugin exits.

If a specific sampling frequency is needed (KHz) set up Foobar's Resampler (SSRC) DSP filter.
If the source is multichannel the "Convert 5.1 to stereo" filter has to be added (see Foobar's DSP options)
Don't use the "Convert 5.1 to stereo" filter if you've got a stereo (2.0) DTS-track.

The conversion is done through Foobar's Diskwriter. All format specific options are adjusted in the diskwriter settings tab.
