Title: Is there any software for real-time DTS encoding?
Post by: Masza on 2013-01-09 17:02:25
I would like to encode all of the stuff (music, videos, movies, games etc.) I listen through PC at least to DTS 2.1. Is there any software that could do this?
I have only the motherboard soundcard, motherboard is Asus P5Q PRO and the audio chipset in it is Realtek ALC1200.

Or is there or could there be a plugin for example for foobar2000 that could encode DTS sound real-time with variable channel mapping?

I've also tried AC3Filter with Media Player Classic and it can encode Dolby Digital from any music or video file but I have one problem with it. When it encodes on the fly the audio drops out when the volume level of the music/video file is low enough. I listen all the stuff through Onkyo PR-SC5508 av-preamplifier. When I hear the DD played and encoded on PC I can check from the display option the audio stream that is coming in. It shows "DD 2.1 / fs: 44100 Hz" for example. But when the sound disappears (when the volume level in the music file is low enough) it just shows "Unknown". Where is the problem? The Onkyo doesn't have any problems with any DVD or Blu-Ray players.

using foobar2000 with foo_record ( http://www.saunalahti.fi/~cse/foobar2000/foo_record.zip (http://www.saunalahti.fi/~cse/foobar2000/foo_record.zip) ) and dcaenc.exe ( https://github.com/lordmulder/LameXP/blob/m...nc.exe?raw=true (https://github.com/lordmulder/LameXP/blob/master/res/tools/dcaenc.exe?raw=true) ) you can record to dts in real-time...

Assuming that Masza has a 'Stereo mix' input then that would work.

If your soundcard driver doesn't have a 'Stereo mix' input and you use Windows Vista/7/8 then you can still capture audio in WASAPI loopback mode:

Some interesting links on WASAPI audio capture:

It won't work on DRM protected content:

WASAPI does not permit loopback recording of digital streams that contain DRM-protected content. Similarly, a trusted audio driver does not permit a loopback device to capture digital streams that contain protected content. Windows Vista allows only trusted drivers to play protected content. For more information about trusted drivers and DRM, see the Windows DDK documentation.
