Re: [Musicpd-dev-team] S24_3LE output?
Is S24_3LE packed 24-bit? Yes. I apologize if this is the same question, but would the current Redbook-mpd-ALSA-DAC conversions present the exact same bytes to the DAC as Redbook-mpd-DAC if mpd were outputting S24_3LE? Red book? That's a CD standard and it is 16 bit by definition. MPD can not play CDs. I should have been more clear about what I meant. Would a 16-bit file converted to 32-bit by mpd and then converted to S24_3LE by ALSA be bit-for-bit identical to a 16-bit file converted to S24_3LE by mpd if mpd it were able to do so? - Grant -- This SF.Net email is sponsored by the Verizon Developer Community Take advantage of Verizon's best-in-class app development support A streamlined, 14 day to market process makes app distribution fast and easy Join now and get one step closer to millions of Verizon customers http://p.sf.net/sfu/verizon-dev2dev ___ Musicpd-dev-team mailing list Musicpd-dev-team@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/musicpd-dev-team

Re: [Musicpd-dev-team] S24_3LE output?
Can mpd be made to output S24_3LE? No, not without a patch. What format does mpd output? - Grant Demian mentioned that mpd outputs in a 32-bit format. I'm wondering if 16-bit audio converted to 32-bit by mpd, and then converted to S24_3LE by ALSA would end up adding noise? I brought this up on the ALSA list and they basically said it depends on how mpd converts to 32-bit. It depends on how the bits are added. Usually the bits added are low order bits-- this is to ensure that roundoff error does not keep adding noise to the system, and to use a common calculational track no matter wha the input, and so they use a size that is bigger then any possible. On the other hand they may want extra headroom and add the padding at the high end instead. Can anyone here shed any light on how mpd does this, and whether or not 16-32-24 would add noise in this case? - Grant -- This SF.Net email is sponsored by the Verizon Developer Community Take advantage of Verizon's best-in-class app development support A streamlined, 14 day to market process makes app distribution fast and easy Join now and get one step closer to millions of Verizon customers http://p.sf.net/sfu/verizon-dev2dev ___ Musicpd-dev-team mailing list Musicpd-dev-team@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/musicpd-dev-team
