Hi guys!

This plugin (foo_input_sacd_hq) is patched version of Super Audio CD Decoder plugin v0.5.11 with added high-quality DSD->PCM 88.2/96 kHz conversion.

http://dl.dropbox.com/u/18475891/foo_input_sacd_hq.zip

Technical details of patched version:

- single-pass double precision processing;
- 24-bit dithering;
- SSE2 required;
- 88.2 kHz sample rate support (32x downsampling);
- 96 kHz sample rate support (5/147 polyphase filter);
- 2.8 mHz DSD stream support;
- filters were selected by ear.

Removed functionality in patched version:

- DSD stream output (PCM only);
- 44.1 kHz support (doesn't make sense);
- 176.4 kHz support (my audio interface doesn't support it);
- 5.6 mHz DSD stream support (didn't find any to check);
- all another DSD->PCM algorithms (BTW, only double precision multistage
one sounded good for me).

Conclusion:

New filters added depth and feel of SACD in PCM output. I can't say that sound of converted PCM stream is better then native SACD player one but results are really comparable.

PS. Also this plugin capable to play 5.1 with 55%/61% load on my CPU (Athlon 7750 2.7 GHz).

PPS. Also single-precision version with lower CPU load available in "bonus\single-precision-version" directory of archive.
